    Description: The invention relates to a power supply device for supplying several consumers with direct current, the consumers being connectable to a first direct current source via a bus line of a first energy bus. The invention also relates to a method for operating the power supply device.
    [0002] Such a power supply device is known, for example, from DE 10 2013 225 815 A1.
    Consumers of railway signal systems are usually supplied with power via a central point (signal box). The field elements are powered by switching on the systems in the signal box.
    [0004] DE 10 2013 225 815 A1 discloses a power supply device with which the power supply takes place via a bus line of an energy bus.
    The energy distribution thus shifts along the energy bus. In this way, cost-effective power distribution over long distances (here: distances of 20-50 km) can take place, since bus systems can handle material fluctuations statistically distributed over a given route more efficiently with a given use of metallic conductors (especially copper or aluminum). However, errors in power distribution can no longer occur in the signal box, but are handled by active elements of the power bus system.
    Overall availability is challenging because many consumers (field elements) are connected to a bus line. Due to the large number of consumers, an extremely high inrush current arises when switching on (starting up the distributed power supply of the consumers (field elements)).
    [0007] The material-efficient use of metallic conductors means that the bus line has a higher resistance than conventional energy distribution systems, so that power fluctuations cause larger voltage fluctuations.
    It is an object of the invention to propose a power supply device in which, on the one hand, the loads can be reliably supplied with power via a bus line, in particular also in the event of a fault, and on the other hand, the inrush current and thus the voltage drop can also be kept under control for many consumers.
    This object is achieved by a power supply device according to claim 1 and a method according to claim 12.
    An "energy bus" denotes a successive arrangement of several consumers along a (2-pin) bus line with a common feed. According to the present invention, in addition to the bus line, the power bus also comprises consumer bus coupling elements which are arranged along the bus line, that is to say one behind the other, and which divides the bus line into bus segments, and, depending on the number of feeds (DC sources), feed-in bus coupling elements via the current can be fed into the bus line from the direct current source (s). An energy bus can have a linear (open bus line) or a ring-shaped (closed bus line) topology. The current flow within the energy bus is bidirectional.
    According to the invention, the bus line is divided into bus segments by consumer bus coupling elements such that each consumer bus coupling element comprises switching elements for electrical isolation of the bus line, so that the bus coupling elements each have a basic state and / or a first operating state in which the bus line is electrically interrupted by the corresponding consumer bus coupling element, and can be brought into a second operating state in which the bus segments are electrically connected by the corresponding consumer bus coupling element, and that at least one of the consumers is connected to one of the consumer bus coupling elements and thus supplies this consumer. Any number of consumer bus coupling elements can be arranged within a bus line.
    A consumer is connected to at least one consumer bus coupling element, so that this is supplied by the consumer bus coupling element, the consumer bus coupling elements generally. are functionally independent of the respective consumers. However, there can also be bus coupling elements that do not supply any consumers.
    According to the consumer bus coupling elements form interruption points at which the bus line can be interrupted. The disconnection / interruption of the bus line is the lack of an electrically conductive connection between adjacent bus segments. This achieves electrical insulation in the voltage potential range of the operating voltage.
    The inventive separation of the bus line into several bus line sections (bus segments) by the consumer bus coupling elements (electrical interruption of the bus line at interruption points) enables the consumers to be switched on sequentially and thus to reduce the current peaks that occur when the consumers are switched on.
    As switching elements e.g. electromechanical relays or electronic switching elements such as thyristor, transistors and FETs are used.
    The consumer bus coupling elements preferably each include the aforementioned switching elements, a small processor for operating these switching elements, electronics for line diagnostics, and filters and protective devices. At the interface to the consumer, the small processor operates and monitors the wide-range power supply of the consumer as the actual payload.
    In a particularly preferred embodiment, the consumers are components of the control and security technology, in particular field elements, the consumers each comprising a logic or a processor.
    The power supply device according to the invention is therefore preferably used in railway technology, in particular in control and security technology.
    [0019] Field elements are elements which are arranged along a rail transport route, in particular switches, signals, etc. The field elements preferably each comprise a wide-range power supply (in particular 450 VDC - 900 VDC; approx. 500 W - 1 kW), diverse electronics Processors and a connection to the data communication network.
    In a first preferred embodiment, the power bus has a linear topology and the first DC power source is the only DC power source of the first power bus. In this case, for example, only the first consumer bus coupling element can be directly connected to the first direct current source (that is, without the interposition of a further consumer bus coupling element equipped with a consumer). The other consumer bus coupling elements then each connect to the preceding consumer bus coupling element (entry point at one of the two ends of the power bus. The current is fed in here only at a single point. In the event of a fault, the entire bus or parts of the However, it is also possible to arrange the first direct current source at any point on the power bus, for example between two consumer bus coupling elements, and the current is then fed into the bus line from the single direct current source in two directions.
    A second embodiment of the power supply device according to the invention provides that the first and the nth consumer bus coupling element are connected directly to the first direct current source, so that the power bus has an annular topology. This embodiment enables current to be fed in on both sides by means of only one direct current source. In this way, despite the occurrence of an error in a segment of the bus line, all consumers can be supplied with power (first stage troubleshooting).
    The bus line is preferably electrically connected to a further (that is to say a second, possibly also a third, fourth, etc.) direct current source (third and fifth embodiment).
    In the third advantageous embodiment, one of the consumer bus coupling elements, preferably the nth consumer bus coupling element, is connected directly to the further (in particular the second) direct current source.
    In this embodiment, the power bus has a linear topology with a two-sided supply of current by means of two direct current sources.
    For the purpose of increased availability, it is advantageous if more than one further direct current source (ie a total of more than two direct current sources) are electrically connected to the bus line (third and fifth embodiment).
    From this variant, troubleshooting of the first and occasionally second stage can be implemented.
    It is particularly advantageous if a bus coupling unit is present which couples the first energy bus to a second energy bus. A bus coupling unit has at least four connections (coupling two energy buses) and can assume any electrically permissible positions (in particular, short-circuit-free pair-wise coupling of the two-pole bus lines), including multiple positions.
    [0028] More than two energy buses can also be coupled to one another via the same coupling unit. In addition, a power supply device can also comprise a plurality of coupling units, which each couple at least two energy buses to one another.
    In the case of an annular topology of the energy bus (s), the bus coupling unit divides the annular bus line (s) of adjacent energy buses into a first line section and a second line section. If an error occurs both in the first line section and in the second line section of an energy bus, the consumers that can no longer be supplied by the bus-own direct current source can then be supplied by the direct current source of the second bus (second stage fault rectification). For this purpose, the bus coupling unit comprises, for example, further switching elements for electrically connecting the line section of the first energy bus that can no longer be supplied to the second energy bus.
    A fourth embodiment provides that the first and the second power bus (preferably all power buses of the power supply device) have an annular topology. This embodiment is particularly advantageous when large distances have to be covered with high availability, for example for connecting two railway networks.
    A fifth and sixth embodiment provides that the first and the second power bus (preferably all power buses of the power supply device) each have a linear topology. This embodiment can advantageously be used to connect large track fields.
    In a seventh embodiment, an energy bus with an annular topology and an energy bus with a linear topology are coupled to one another by the bus coupling unit.
    Preferably, the consumer bus coupling element on both the negative and on the positive potential side of the bus line each have a first switching element for electrical isolation of the bus line and a second switching element for connecting the consumer to the power bus, the first switching elements being part of the bus line and the second switching elements are part of a supply line integrated in the consumer bus coupling element and leading from the bus line to the consumer.
    In the following, a method for operating a power supply device described above is described, in particular for use in railway technology. According to the invention, the consumer bus coupling elements are brought sequentially from the basic state into the second operating state, so that the consumer bus coupling elements are switched on sequentially by being supplied with current from the direct current source.
    Preferably, the current from the direct current source is fed into the bus line on both sides.
    At least one further direct current source can be used for the supply on both sides. This enables the linear topology of the energy bus to be used. Preferably more than two DC sources are used. By controlling the voltage of the DC sources, the energy supply can be balanced in the bus under resistance.
    As an alternative to this, an energy bus with an annular topology and a single direct current source can be used for the two-sided supply.
    [0038] The direct current sources feed current into the energy bus by means of a feed-in bus coupling element in each case. Any number of direct current sources can be provided within an energy bus. The number of infeed bus coupling elements depends on the number of direct current sources.
    Preferably, the feed bus coupling elements comprise a series of switching elements and diodes. The switching elements separate the bus at the segment boundaries and allow controlled, independent feeding of the current into the adjacent bus lines. The diodes or controlled switches decouple the supply (DC sources) in the event of reverse energy input (e.g. by using additional DC sources with short lines and different voltages).
    All the power supply devices described can be designed as potential-free IT (Isole Terre) power supply networks. This network standard is preferably used in rail technology, especially in control and safety technology.
    In the event of a defective segment of the bus line (e.g. in the event of an interruption or short circuit), the consumer bus coupling elements adjacent to the defective segment are preferably set to the first operating state. The bus line is then interrupted at the defective point. Due to the feed-in on both sides, all consumers can still be supplied with electricity. In the event of a short circuit in a bus segment, the affected bus segment is isolated by the neighboring consumer bus coupling elements.

Likewise, according to the invention, the features mentioned above and those which have been elaborated further can be used individually or in combination in any combination.

    1 shows an energy bus according to the prior art with two direct current sources PS1, PS2, which are electrically connected to a plurality of consumers (field elements FE) via a bus line L. For this purpose, the bus line L has branch lines A, which lead to the field elements FE. If a fault, for example a short circuit, occurs in such an arrangement, this affects the entire power bus, so that none of the field elements FE can continue to be operated. Due to the large number of field elements FE, a high switching current also occurs.
    2a, 2b show two variants of a first embodiment of the power supply device SV1, SVT, each with an energy bus that has a linear topology. The power bus comprises a bus line L3, a first direct-current source PS1 which feeds in on one side and a feed-in bus coupling element SBA1 by means of which current is fed into the bus line L3. Interruption points U1 ... Un, US1 ... USm (here: m = 1) are provided in the bus line L3, at which n consumer bus coupling elements VBA1 ... VBAn and the infeed bus coupling element SBA1 divide the bus line L3 into bus segments BS , The number s of bus segments is dependent on the number n of consumer bus coupling elements and the number m of feed bus coupling elements. The number s of bus segments in an energy bus with a linear topology is s = m + n-1. The consumers FE1 ... FEn are each connected to a consumer bus coupling element VBA1 ... VBAn. Using the consumer and the infeed bus coupling elements VBA1 ... VBAn (at interruption points U1 ... Un), and the infeed bus coupling elements SBA1 ... SBAm (at interruption points US1 ... USm), electrical isolation can be made at the corresponding
    Interrupt points are caused (basic state or first operating state - see Fig. 3a, 3b; or disconnection of the feed see Fig. 4). In the examples shown, the fourth consumer bus coupling element VBA4 is not followed by a consumer. Consumer bus coupling elements VBA4 without downstream consumers FE can serve as a reserve for consumers to be connected in the future.
    In Fig. 2a, the first DC power source PS1 is only directly connected to the first consumer bus coupling element VBA1 and thus form the limit of the energy bus (one-sided supply).
    2b, the first direct current source PS1 is arranged between two consumer bus coupling elements VBA2, VBA3. The energy bus thus has a two-part linear topology. The feed bus coupling element SBA1 can operate the power bus on both sides. This property is also used in the ring-shaped topologies described later.
    A preferred construction of a consumer bus coupling element VBA installed in a bus line L is shown in FIGS. 3a, 3b and 3c. The consumer bus coupling element VBA comprises switching elements S1, S2, diodes D and a small processor KP. The diodes are used to connect the small processor KP and the consumer FE to the bus line L. Via the switching elements S1, the bus line L is interrupted, in other words segmented into bus segments. The switching elements S2 are used to connect the consumer. The switching elements S1, S2 are preferably designed as relays or electronic switching elements.
    The consumer bus coupling element VBA has the following operating states: In the basic state shown in FIG. 3a, the small processor KP is fed on one or two sides by the bus line L via the diodes. All switching elements S1 and S2 are open. In the first operating state shown in FIG. 3b, the consumer FE is switched on by means of the second switching elements S2. After a time delay, the bus line is connected through to the first switching elements S1, as shown in FIG. 3c (second operating state).
    The power supply device according to the invention, as shown, for example, in FIG. 2a, is operated according to the invention in such a way that initially all consumer bus coupling elements VBA1 ... VBAn are in the basic state, so that the bus line L3 through each of the consumer bus coupling elements VBA1 ... VBAn is interrupted electrically. By switching on the current of the direct current source PS1, therefore, only the consumer bus coupling element (first consumer bus coupling element VBA1) closest to the direct current source PS1 is initially supplied with current, so that the first consumer bus coupling element VBA1 itself and the consumer FE1 connected downstream of the first consumer bus coupling element VBA1 can be switched on. The functionality of the consumer bus coupling element VBA1 switches itself on when the supply SP1 is present. In the course of this connection process, the consumer power supply is switched on by closing the second switching elements S2. The consumer bus coupling element VBA1 is then in the first operating state. If these voltages are stable, the electronics of the consumer FE1 are switched on. After the consumer FE1 of the first consumer bus coupling element VBA1 is ready for operation (switched on / started up), the first consumer bus coupling element VBA1 is brought into the second operating state, i.e. the bus is switched through to the next (second) consumer bus coupling element VBA2 by means of the switching elements S1, as a result of which the next consumer bus coupling element (second consumer bus coupling element VBA2) is supplied with current, etc. The consumers FE1 ... FEn are therefore switched on one after the other , so that even when using a large number of consumers FE1 ... FEn, only the low starting current of a single consumer FE1 ... FEn occurs.
    FIG. 4 shows the basic form of the construction of a feed-in bus coupling element SBA, a direct current source PS being connected to the bus line L via the feed-in bus coupling element SBA. The feed coupling takes place here via diodes D1. These decouple the PS supply in the case of reverse energy input (e.g. by a second supply (see e.g. Fig. 6a) for short cables and different voltages). The diodes D1 can also be implemented as controlled switches. The diodes D2 serve to decouple the power supply of the small processor KP. Switching elements S3 and S4 serve to separate the potential-free feed PS from the bus line L. By staggering the connection by means of the switching elements S3 and S4, two-part linear energy buses, as shown in FIG. 2b, can also be started up sequentially.
    5 shows a second embodiment of the power supply device SV2 according to the invention. In contrast to the power supply device SV1 shown in FIG. 2, the power bus of the power supply device SV2 according to FIG. 5 has an annular topology. For this purpose, the direct current source PS1 is connected via the feed bus coupling element SBA1 both to the first consumer bus coupling element VBA1 and to the nth consumer bus coupling element VBAn, so that current can be fed in from both sides. The bus line L1 is divided into n + m bus segments BS by the bus coupling elements SBA1, VBA1 ... VBAn.
    A further possibility of how a power supply on both sides can be realized is shown in FIGS. 6a-c. The third embodiments of the power supply device SV3, SV3 'according to the invention shown there include an energy bus with a linear topology. 6a shows an embodiment SV3 with three direct current sources PS1, PS2, PS3. 6b, c show an embodiment SV3 'with two direct current sources PS1, PS2. In both cases, each consumer bus coupling element VBA1 ... VBAn can be fed from two sides. The sequential startup then preferably takes place starting from the two direct current sources PS1, PS2 simultaneously from both sides of the energy bus. For this purpose, the first consumer bus coupling element VBA1 is connected to the first direct current source PS1 via the infeed bus coupling element SBA1 and the nth consumer bus coupling element VBAn is connected to the further direct current sources PS2 via a further infeed bus coupling element SBA2. In the event of an error (short circuit KS) in the bus segment BS '(FIG. 6c), the relevant bus segment BS' can be isolated by the adjacent consumer bus coupling elements (here: consumer bus coupling elements VBA2, VBA3) by opening the switching elements S1 are brought into the first operating state, as shown in FIG. 6c. The consumers FE1, FE2 can then be supplied via the first direct current source PS1, the consumers FE3 ... FEn via the further direct current source PS2 (first stage troubleshooting).
    7a-c show a fourth embodiment of the power supply device SV4 according to the invention, in which a first power bus B2 with a bus line L1 with a second power bus B2 'with a bus line L2 are electrically coupled by means of a bus coupling unit K. The bus lines L1, L2 are each by the bus coupling unit K in a main line section L1a, L2a, in which at least two consumer bus coupling elements VBA1 ..... VBA5 are arranged, and a return line section L1b, L2b, in which consumers are not necessarily -Busan coupling elements are arranged, divided. Consumer FE1, ..., FE5 are connected to the consumer bus coupling elements VBA1, ..., VBA5. Both energy buses B2, B2 'have an annular topology according to FIG. 5. FIG. 7b shows the case in which a segment of the main line section L1a has been isolated due to an error that has occurred (first stage troubleshooting). Due to the coupling by means of the bus coupling unit K, the consumer bus coupling elements VBA1, ..., VBA5 and the consumers FE1, ..., FE5 connected to this can also in the main line section L1a in the event of an error additionally occurring in the return line section L1b, as in FIG. 7c shown, continue to operate. For this purpose, the consumer bus coupling elements VBA4, VBA5 of the first energy bus B2, which cannot be supplied via the first direct current source PS1 due to the fault in the main line section L1a and return line section L1b, are electrically connected to the second energy bus B2 ′ by means of the bus coupling unit K (second stage troubleshooting).
    8 shows a fifth embodiment of the power supply device SV5 according to the invention, in which two energy buses B1, BT with linear topology and in each case two direct current sources PS1, PS2, PST, PS2 'are electrically coupled by means of the bus coupling unit K.
    Five consumer bus coupling elements VBA1 ... VBA5 are connected to the first energy bus B1, the first direct current source PS1 being only electrically connected directly to the first consumer bus coupling element VBA1) and thus feeding current in only one direction. The further DC power source PS2 is arranged between the third consumer bus coupling element VBA3 and the fourth consumer bus coupling element VBA4 (that is, both electrically connected to the third consumer bus coupling element VBA3 and to the fourth consumer bus coupling element VBA4), so that an infeed done in two directions. The second power bus BT comprises two direct current sources PST, PS2 'and three consumer bus coupling elements VBAT ... VBA3', to each of which a consumer FET ... FE3 'is connected. In this embodiment as well, due to the coupling by means of the bus coupling unit K, the consumer bus coupling elements VBA1 ... VBA5, VBAT ... VBA3 'and the consumers connected to them can continue to be operated if an error occurs. In particular, the consumer bus coupling elements VBA4, VBA5, VBAT can be supplied with current from the current source PS2, PS2 'of the respective other energy bus B1, BT (first stage troubleshooting).
    [0074] This embodiment of the power supply device also masters additional errors (higher-level troubleshooting). The failure of the DC power source PS2 in the first power bus B1 is described as an example. If the voltage is lost, diodes in the infeed bus coupling element SBA2 (corresponding to the diodes D1 in the infeed bus coupling element SBA in FIG. 4) isolate the voltage source PS2 from the bus line. The switching elements S3 and S4, controlled by the small processor KP (see FIG. 4), remain closed. Even when the coupler K of the infeed bus coupling element SBA2 is open, the consumer bus coupling elements VBA4 and VBA5 are thus supplied by the first direct current source PS1.
    9 shows a sixth embodiment of the power supply device SV6 according to the invention, in which, for example, four power buses with a linear topology and in each case one direct current source PS1, PST, PS1 ", PST" are electrically connected in a star shape by the coupling unit K. Such a “star-shaped” coupling is generally possible with n energy buses, with n> 2, it being possible for a power supply device coupled in a star-shaped manner to comprise both energy buses with a linear and with a ring-shaped topology. The coupling unit K must have a sufficient number of connections in accordance with the number and topology of the energy buses to be coupled.
    10 shows a seventh embodiment of the power supply device SV7 according to the invention, in which an energy bus B1 with a linear topology (analogous to FIG. 2) is coupled to an energy bus B2 with an annular topology (analogous to FIG. 5) by means of the bus coupling unit K. Both energy buses B1, B2 each include a direct current source PS1, PST. Five consumer bus coupling elements VBA1, ..., VBA5 are connected to the bus line L3 of the first power bus B1. Four consumer bus coupling elements VBAT,..., VBA4 'are arranged in the second power bus B2, the consumer bus coupling element VBA4' not being located in the main line section L2a but in the return line section L2b of the bus line L2. With this embodiment, first and second stage bug fixes are possible. The bus coupling unit K can assume all possible combinatorial positions (between the connections used).
    All embodiments include a segmented power bus, the segmentation being implemented by consumer bus coupling elements and feed-in bus coupling elements, which are brought from a basic state in which the segments of the bus line adjoining the respective bus coupling element are electrically separated from one another into a second operating state can be in which these segments are electrically connected. The switchable segmentation is an essential performance feature for localizing line faults (diagnostic function).
