    The invention relates to a device for the controlled combustion of a hydrogen-air mixture, which is part of the gas mixture of a nuclear installation, mainly as part of a plant with a nuclear reactor, with at least one ignition source, to which one spark ignition device is connected.
    The present invention is based on the task of creating a device of the aforementioned type in which the formation of large volumes of flammable mixtures of hydrogen with air is prevented with a high degree of reliability. The next task is to show the chassis and housing design, which is reliable in operation and durable with respect to overpressure, for a device in which the ignition source, including energy storage, triggering elements and connecting parts, can be placed reliably with respect to overpressure and high voltage electrical and mechanical wiring.
    A device is known for the controlled combustion of a flammable hydrogen-air mixture in a nuclear installation, containing a spark igniter connected to the converter and an ignition source.
    According to the invention, the task is solved using a device of the above type with the following features; a) the ignition source is equipped with an autonomous energy storage device, b) at least one temperature-dependent triggering element and at least one second one are provided for initiating the ignition process.
    triggered depending on the pressure value, the initiation element, and the first initiation element is in a heat-conducting contact, and the second initiation element is in contact with the gas mixture capable of transmitting the pressure force, c) both initiation elements are switched on in such a way that when only one initiating element is triggered, a signal for discharging an energy storage device into a spark igniter, and during an emergency that may last for a long period of time, n and spark ignition sparks arise, which are repeated during this time at certain intervals. Preferred other forms of execution are indicated in paragraphs 2-14 of the claims.
    By autonomous, it should be understood that the energy storage device does not need supply lines, be it cables or other lines for supplying energy, so that there is no dependence on one or the other located at a distance from the energy storage device or energy source. This or these are rather directly subordinate to the source of ignition.
    In a preferred embodiment, the energy storage device is a dry battery or a dry battery installation of a high voltage ignition unit with a spring or electronic switch in the current circuit of a dry battery, as well as a high voltage module, a charging capacitor and a spark igniter. This electronic or spring switch is hereinafter referred to as the initiating switch, it has at least two. contact sections arranged parallel to one another, wherein one contact section is actuated by a sensor of at least one first initiating element and a second contact section is sensed by at least one second initiating element. One initiating element includes at least one contact portion and at least one sensor that controls this portion. Particularly favorable is such a design when the initiating switch has another, parallel-connected contact portion, which may be a reed contact portion, which is simultaneously a magnetic field dependent sensor. Thanks to the control magnet brought in from the outside of the device, this reed contact area can be closed and thus a jump of the sparks on the spark igniter is artificially created, with the help of which, in addition, evidence of the correct operation of the ignition source or sufficient battery power is obtained. As a battery or battery installation according to a preferred embodiment, a lithium-rechargeable battery is used, which at satisfactory temperatures of about 200 ° C works satisfactorily, that is, flawlessly for a period of time from 4 to 5 days.
    The advantages achieved by the invention should be seen in the fact that the redundancy and reliability of operation of the device is significantly higher. If a flammable hydrogen-air mixture is formed, then it can be used to prevent a rise in temperature, • increase in pressure, or both. Due to the fact that the device according to the invention has at least two triggering elements, namely, triggering elements depending on temperature and pressure, which provide a position in which at least one signal causes the device to trip. Such a signal may be a temperature signal or a pressure signal. In addition, reliability increases with the failure of one initiating element.
    The reliability of the device according to the invention can be improved if at least two sensors with corresponding contact areas are provided for each initiating element, so that at least two sensors respond to one physical quantity (in particular, temperature) and at least two others
    sensor of another initiating element - to another physical quantity (in particular, pressure). This conditions one of four triggering conditions. (If there is a reed contact area), the fourth type of initiating element could include at least one gas analyzer that responds to the concentration of hydrogen in the hydrogen-air mixture analyzed by the device, so that another physical quantity is available as a criterion for initiating the ignition process .
    Below, on the basis of the drawings, exemplary embodiments of the invention and other advantages are described. The principle of the subject of the invention is explained in more detail below. The simplified drawings show:
    FIG. 1 is a schematic diagram of a simplified view of a device according to the invention with an ignition source, including a dry battery, a high voltage module and a spark section, the device having three initiating elements independent of each other.
    FIG. 2 is an example of the device of FIG. 1, and the electrical circuit is presented in more detail, with a clock generator, a protective diode and a high-voltage ignition transformer,

    FIG. 6 - sectional view along the section plane
    VI to VI according to FIG. 3 and
    FIG. 7 is a bottom view of the device of FIG. 3.
    According to FIG. 1, the positive line 1.1 and the negative line 1.2 are dry, the batteries 1 are connected to the input terminals 4.1,4.2 of the high voltage module 4, and the negative terminal 1.2 includes a multi-pole switch 2, which in the case shown has three contact sections 2.1.2.2 parallel to each other and 2.3. Using the arrows F1, F2 and F3 it is shown that the contact areas shown in the position are open due to external factors acting on them, if they exceed the set value, they can be put into the closed position. In the example, F1 means an analogue value with respect to temperature T of the controlled gas mixture of a nuclear reactor installation, F2 is an analog value with respect to pressure P of this gas mixture, and F3 is an analog value with respect to the magnetic field of the test magnet. Using the magnetic field H, the contact section 2.3 made in the form of a reed contact can be closed at any time for testing purposes, for example, to check the charging status of the dry battery 1 and the operability of spark igniter 6. The contact sections 2.1-2.3 have both fixed contacts K a , but movable contacts K c . In this case, we can talk about electronic-mechanical switches, which in the opening direction are under the load of the spring and if the acting values of F1-F2 exceed the mentioned limit value, they can be triggered to close. Contact areas 2.1-2.3 can also be formed using electronic switches. Sensors 3.1 (temperature sensor), 3.2 (pressure sensor) and 3.3 (reed-contact area), which are shown schematically as temperature-dependent, pressure-sensitive, and magnetic-field-sensitive sensors, are used for which the dashed lines show that when the above limit values are exceeded values are formed analog, causing the contact closure signal ^ F1 or F2 or F3. The first initiating element AE1 includes a temperature sensor
    3.1 and contact section 2.1, in the “composition of the second initiating” element AE2, a pressure sensor 3.2 and contact section 2.2 and in the composition of the third initiating element AEZ, a sensor 3.3 depending on the magnitude of the magnetic field and contact section 2.3.
    To the output terminals plus ”and minus 4.3 and 4.4 of the high voltage module 4, the spark section 6a and 6b of the electric spark fuse 6 is connected using high voltage electric lines
    6.1 and 6.2. Charging resistance 8 is located on line 6.1, and between charging resistance 8 and spark section 6 and both lines 6.2, 6.2 are connected to each other using a charging capacitor 5. Spark ignition 6 is equipped with a gas-tight device for protection against splashes. As you can see, all the nodes of this ignition source, indicated generally by Z1, with the exception of spark ignition 6, are protected from moisture, pressure and temperature and placed inside the metal housing 9 and connected in it by cable wiring Through the wall of the metal housing 9 pass only the electrical wiring spark igniter 6 and the wiring device for measuring pressure (in Fig. 1 shown, but will be explained later using Fig. 3).
    In case of operation, for example, when the temperature in the controlled gas mixture is exceeded, the set temperature limit value is exceeded. In this case, according to arrow F1, the temperature-dependent initiating element AE1 is triggered. In this case, in accordance with a preferred embodiment, we are talking about a thermal switch (not shown in Fig. 1), the Contact section 2.1, which can be serviced from the side of the thermal switch, closes and direct current is supplied to the high voltage module 4 from the side of dry battery 1. The high voltage generated in this module 4 is output to its terminals 4.3,4.4, it creates due to the resistive-capacitive combination 8-5, which has a sawtooth shape. high ignition voltage 6a, 6v. The time interval of ignition pulses (cycle time) can be several minutes, because after appropriate periodically repeating flare or hydrogen flaring operations, a certain time elapses until a newly flammable mixture forms. Battery 1 has a capacity in which ignition processes carried out at regular intervals or periodically repeating can take several days. High voltage module 4 is most preferably an electronic unit that converts the direct voltage of a low voltage dry battery to the desired high voltage or spark discharge voltage. At the same time, it converts direct current to pulse current. In principle, in the ignition source Z1 according to FIG. 1 instead of an electronic switch or chopper (for example, a transistor), one could ’provide a mechanical chopper, although electronic design should be preferred.
    At the ignition source Z2 according to FIG. 2 some switching elements of the high voltage module are presented in more detail. The clock generator 13 in the event of the closure of one of the contact areas 2.1-2.3 of the switch 2 generates a sequence of pulses to the base additional sequentially on
    10 · valuable high voltage transistor
    11. A protective diode 10 is connected in parallel to its base-collector section. Its emitter is connected to the negative line 1.2. A charging capacitor 5 is connected between the emitter and the collector. On the path between the positive line 1.1 of the dry battery 1 and the collector, the primary winding 12a of the ignition transformer 12a of the ignition transformer 12 is turned on. Through it, in the case of a conductive transistor 11, tk battery flows through the emitter-collector section. In this case, it accumulates inductive energy. In the event that the transistor 11 is closed due to the corresponding biasing voltage of the base, then in this case a high voltage or ignition voltage is induced in the secondary winding 12v. It leads to a discharge in the form of igniting sparks in the spark section. The transistor 11 operates like a transistor of a transistor ignition circuit in a car.
    The ignition sources Ζ1 (Fig. 1) and Ζ2 (Fig. 2) described above are used for the controlled combustion of combustible hydrogen-air mixtures in nuclear installations. First of all, they should be understood as installations with a water-cooled nuclear reactor, that is, installations of nuclear reactors cooled by water under pressure, installations with a boiling reactor or installations with reactors on heavy water, which within the Steel and / or concrete shell have a capacity, in which in the event of an accident a flammable hydrogen-air mixture may form. The latter, with the use of ignition sources Ζ1 and / or расположены2, which are located inside the vessel • at a distance from each other, can be deliberately burned. In FIG. 1 and FIG. 2 presents the basic concept;
    a) the ignition source is equipped with an autonomous, checked at regular intervals in relation to the state of charge of the energy storage device 1. The latter is most preferably a dry battery, which operates reliably to a temperature of approximately 200 ° C. Especially suitable for this purpose are the so-called lithium batteries;
    b) to initiate the ignition process, in addition to at least one first, temperature-triggering initiating element AE1, at least a second pressure-triggering initiating element AE2 is provided, the first initiating element AE1 with its temperature sensor 3.1 is in heat-conducting contact with the controlled gas mixture, and the second initiating element AE2 with its pressure sensor 3.2 is in contact with the controlled gas mixture, transmitting the pressure force, as It is further explained with reference to FIG. 3-7. In the case of the third initiating element AEZ, which includes a sensor 3.3 depending on the magnitude of the magnetic field, contact section 2.3, arrow F3, we are talking about a device for checking operability, which is explained below. As already mentioned above, it would be possible to provide another initiating element that would respond to a different physical quantity, for example, to the concentration of hydrogen in a “controlled gas mixture (not shown in FIG.);
    c) at least two initiating elements AE1 and AE2 are turned on in such a way that when only one initiating element AE1 or AE2 is triggered, the energy storage device 1 will be discharged to spark ignition 6, and in case of an emergency that may last for a long time, for example, 3-5 days, ignition sparks appear on the spark ignition 6, which during these periods of time will be repeated at certain intervals. · The initiating elements AE1, AE2 are connected to each other according to the principle of the OR condition, that is, their contact sections 2.1 and 2.2 are connected in parallel руг Friend to friend. The cycle time can be, as indicated above, mainly several minutes, because after burning a certain amount of hydrogen, some time must pass before a flammable mixture forms.
    In FIG. 3-7 show the mechanical-electrical embodiment of the ignition sources according to FIG. 1 and 2. The pressure-resistant capsule for the metal casing 9 is formed by a pressure-resistant steel casing 9.1, which has an annular flange 9.2 in the region of the lower opening of the casing. A massive lower plate 9.3, which, like parts 9.1 and 9.2, is made of corrosion-resistant steel, is connected to this ring flange 9.2 by means of a flange, ensuring pressure tightness. At least one O-ring 14 is located between the annular flange 9.2 and the lower plate 9.3, which is placed in the corresponding annular groove 15 and, in the shown combined state of parts 9.2 and 9.3, is compressed by the principle of elastic deformation. The flange bolts are marked as 16, their heads as 16.1, their threaded rod as 16.2, the corresponding threaded holes in the bottom plate 9.3 are indicated as 16.3 and the through holes in the annular flange
    9.2 as 16.4. And only one flange bolt 16 is shown in more detail, on the opposite side of the flange connection 9.2-9.3, the flange bolt 16 is shown in the form of an axial line.
    From the inside of the massive lower plate 9.3, a triggering element AE1, depending on the temperature, is integrated. This initiating element is in the form of a capsule and is in heat-conducting contact with the massive bottom plate 9.3. In this case, we are mainly talking about a thermocouple in the design of the so-called thermal switch, both of which protrude in the upward direction of the contact sensors which are designated as 17.1 and 17.2. The electrical connection between this thermal switch and the assembly 18 of the electronic ignition system filled in with gas-tight execution (shown in the form of a box shown by a dashed-dotted line) is provided with a cable with a plug connection (not shown for simplicity). The named thermal switch combines a temperature sensor and a contact area.
    The second initiating element AE2 (see FIGS. 1 and 2) is a pressure switch AE2, which ^ is attached to the upper metal cover of the table 20.1 of system 20 using the retaining jumper 19 (see FIG. 4). This system 20 is a component fixed on the inside the lower plate 9.3 of the carrier T, on which the elements of the electric and electronic circuits of the electronic ignition system 18 are fixed, including a long-acting battery system 100 and at least one pressure switch DE2. The carrier T has the aforementioned system 20, which is held by spacer bolts 2.3 on the lower plate 9.3 at a certain distance from it, while the bottom cover of the table 20.2 consists of insulating material and the electronic ignition system assembly 18 is located on its lower side, the last mounted on a metal sheet 20.4, which is screwed using discs 21 to provide a clearance to a plate made of insulating material, one of the bolts is shown on the assembly 22. Above the spacers 20.5, the top cover of the table Metal retained by spacers 20.3 parallel or plane-parallel to the bottom cover of the table, on top of the spacer bolts are screwed projecting from the top cover section 20.1 of the ends of the thread fastening nuts 23 Using shims 24 (see. FIG. 6).
    Using the holding bolts 25, the U-shaped holding bar 19 for pressure switch AE2 is mounted on the top cover of the table 20.1 (Figs. 4 and 6). The line of the pressure measurement system 26. passed through to ensure pressure tightness through the massive bottom plate 9.3, is also associated with ensuring pressure tightness with pressure switch AE2 using connecting fittings 27. This fitting 27 includes a flange nut 27.1, with which (not shown in Fig.) the conical mouthpiece is connected to the counter-mouthpiece of the connecting line 27.2 of the pressure switch AE2, respectively also conical in shape. The corresponding (standard) connection node is located outside the bottom plate 9.3 on the extension of the measuring line 26 and is indicated by the number 28. Like the connecting end 27.2 of the valve 27, the connecting end 28.2 is fixedly located on the body and is made in the form of a polyhedron so that it can be tightened with a wrench, and the other connecting end with a conical connecting mouthpiece (invisible in FIG.) using a union nut 28.1 is connected to the connecting end 28.2 to ensure tightness pressure. The latter is made in the form of a small fitting, which is hermetically welded from the outside of the lower plate 9.3. And surrounds the passage opening 29. The latter at the place where the measuring line 26 is introduced by its end 26a is slightly expanded and this end 26a is also welded to the bottom plate 9.3 (ring welds 30 and 31).
    The outwardly extending assembly 26b of the pressure measuring line 26 ends in a pressure measuring head, not shown in FIG., At a place where a suitable pressure measuring place is located.
    The head for measuring pressure can be located at a distance of several tens of centimeters to several meters from the housing 9. As mentioned above, the battery system 100 is also mounted on the top cover of the table. Square 101 with
    14 · one shoulder 101a is screwed to the top cover of the table 20.1, and both fastening jaws 102a and 102b are attached to the shoulder 101 protruding from the top with a screw bolt 103 with two battery cases 100a and 10OV inserted. A screw with a threaded thread 103. which is attached to the shoulder 101b at one end (see welded fastening nut 104) is fitted with one fastening cheek 102b and is screwed to the 101th shoulder using a nut and washer 105 and 106. After installing the batteries of the threaded screw 103, after installing the batteries of the 100th SO, a second fastening cheek 102a is pushed on and tightened with the wing nut 107 and the spring washer 107a. The mounting jaws 102a and 102b are provided with grooved recesses 108 along the perimeter of the retained batteries 100a and 10OW. (The electrical wiring from the side of the battery 100 and pressure switch AE2 towards the electronic ignition system assembly 18 is not shown in Fig., As well as the connecting the cable from this electronic ignition system 18 to the massive pin 32, on the outer end of which is located one of the ignition electrodes 6a from among the two ignition electrodes 6a and 6b).
    The lower plate 9.3 is provided with a centrally located high voltage passage HS for the high potential electrode 6a. The latter is located against the potential electrode of the counter electrode 6v. Both ignition electrodes 6a and 6b can be adjusted in relation to their breakdown gap and are mounted on the holding elements 32 and 33 at a certain distance with respect to the lower plate 9.3. A row of these holding elements is the previously mentioned massive pin 32, which extends through the inserted into the lower plate 9.3 to ensure tightness and is located in the center of the high voltage insulating body 34 and has an adjustable mount 32.1 for its free downward protruding end shaped pin or needle elek. ignition cable 6a. The insulating body 34 has a throat portion 34.1 with an O-ring seal 35. which, through tightness, passes through the hole 9.31 located centrally in the bottom plate 9.3 and is attached to the inside of the bottom plate 9.3 using the nut 34.2, also made from mechanical stability of the insulating material, For the passage of the massive pin 32 through the insulating housing 34, so-called metal-ceramic compounds are available which are characterized by a sufficiently high stability with respect to erature. In order to increase the creep areas, the insulating body 34 is provided with ledges 34.3 and ribs 34.4. The counter electrode 6b is mounted on the side of the free end screwed into the lower plate 9.3 of the spacer bolt 33 - also within the adjustable mount 33.1. Both adjustable mounts 32.1 and 33.1 have one inclined hole 36 into which the needle-shaped ignition electrodes 6a and 6b are inserted, precisely in such a way that they are their own, located at a minimum distance a1 to the opposite ends of the electrodes with respect to their other ends, if you look relative to the horizontal are located obliquely, due to which such a position is ensured that the possible condensate immediately drains down and that the ignition parameter cannot be affected by the breakdown gap a1 vie. Adjustable fasteners 32.1 and 33.1 include centrally located openings 37 at the ends of a pin 32 or bolt 33 that intersect with slanted openings 36. Clamping bolts 38 that are also not shown in FIG. inclined holes and through them pass the pin-shaped ignition electrodes 6a and 6b. If the clamping bolts are tightened after installing the ignition electrodes 6a and 6b and after adjusting the distance between them, then the ignition electrodes will be in a fixed state, and at the free end of the clamping bolts 38 not shown in FIG. locknuts, which serve as a safety measure against twisting.
    For protection against wind and spray water, a protective space 39 is located immediately around the ignition electrodes 6a and 6b, surrounded by a protective casing 40 within the lower plate 9.3 (compare also with FIG. 7). This protective casing * 40 can be made in principle and in the form of a sieve, that is, perforated, so that the gas mixture in the protective space 39 corresponds, as far as possible, to the gas mixture in the installation in sector 40a (Fig. 7) for reasons wind protection for electric spark fuse 6 perforation is not provided. In order to protect against contact, it further makes sense to close the opening of the protective casing 40 located at the bottom with a grill 42 made of heat-resistant insulating material (shown in FIG. 7 in a cutout).
    In FIG. 5 shows a top view of a glass tube of a reed contact portion
    2.3. This contact portion is also shown in FIG. 1 and 2, it is the third initiating element AEZ. It is triggered manually with the help of a test magnet and in accordance with this, the arrows F3 mean the value analogous to the magnetic force, which locks the reed contact section 2.3 in case if using the control magnet approach the reed contact area from the outside. Due to this, it is possible, without opening the pressure-tight housing 9, to check the operability of the dry battery 1 or 100 and the electronic and electrical circuits of the electronic ignition system. Such checks are carried out at regular intervals, for example daily or weekly, and if the test shows that the charge level of the battery system 1 or 100 is insufficient, the batteries are replaced. In this case, we can also talk about recharging batteries.
    The electrical wiring of the reed contact portion in FIG. not shown ,, translated using the magnet to the closed position, the tongues of the contacts are shown by the numbers 2.3a and 2.Sv. On Fig, 5 also shows the outline of the case of the thermal switch AE1, which is made by analogy with the base of the radio tube and is screwed to the bottom plate using mounting bolts 41
