    The subject invention relates to a system for supplying at least one electrical load or an energy storage device with direct current by means of a plurality of rollers, in particular rollers or idlers, a cable car system located electrical generators.
    It is known to design a cableway of a cable car or a support roller for a hoisting rope or for a pull rope with an electric generator in cable car installations. Reference is made to EP-1992539 Bl, EP-2623389 A1 and WO 2008/12019 A1.
    As a result, the movement of a cable car along a suspension cable of the cable car installation by means of this roller generates the electrical energy required in the vehicle, through which e.g. a heater is operated. Inasmuch as supporting pillars or hold-down rollers located on supports of ropeway installations are affected, the required electrical energy for the electric or electronic equipment located on the pillars can be generated thereby. As a result, there is no need to lay electrical lines to the supports.
    In general, the electrical energy generated by such a generator is fed into a battery, from which electrical or electronic devices are supplied with the required power. For the supply of the battery, the alternating current generated by the generator is converted into direct current by means of a rectifier. As a result, the voltage of this direct current is brought by means of a voltage converter to a predetermined constant voltage at which the battery is powered.
    The supply of electrical or electronic devices with power can also be done directly from the voltage converter ago.
    The wheels of trolleys of cable cars or located on supports carrying rollers and hold-down rollers over which hoisting ropes or ropes are carried by cableway systems, for manufacturing reasons or due to wear different diameters and due to different running characteristics different rotational speeds, causing the Outputs provided in this or coupled with these entrainment electrical
    Generators in terms of frequency and voltage different electrical values occur. If the electrical energy generated by these generators is delivered to an associated electrical consumer or to a battery, therefore, there is a need to provide for this purpose a control circuit, which ensures that the electrical load or the battery from the generators forth with power is supplied, which has a predetermined voltage.
    According to the invention, this control circuit is that the output of each of the generators is guided to a respective AC / DC converter, wherein all AC / DC converters are controlled or regulated by means of a control unit so that at least approximately the same constant voltages occur at their outputs , And wherein the outputs of all AC / DC converters are connected to each other and placed on at least one consumer or to an energy storage.
    Preferably, each of the AC / DC converters includes a rectifier whose output is connected to a DC / DC voltage converter. Furthermore, an output of each of the AC / DC converters is preferably applied to the control unit via a common bidirectional control line. In addition, an output of the control unit can be connected to the AC / DC converters via a measuring or output line.
    Preferably, the control unit is formed with an input or output line. Furthermore, a frequency transducer can be applied to the output of the generators. In addition, a current transmitter and a voltage transmitter can each be applied to the output of the DC / DC voltage converter. Furthermore, a temperature sensor can be connected to the generators in each case. Preferably, the outputs of the voltage and frequency transmitters, the current transmitter, the voltage transmitter and the temperature sensors are applied to a control circuit and an output of the control circuit is connected to the voltage converter.
    The object of the invention is explained below with reference to an embodiment shown in the drawing. In the drawings: FIG. 1 a vehicle in a cable car installation, in side view, FIG. 2 shows a circuit arrangement with AC / DC converters for feeding a consumer by means of a multiplicity of generators located on rollers, FIG. 3 shows a circuit arrangement for controlling the voltage of the electrical generated by the individual generators Stromes, FIG.4 a unit with multiple AC / DC converter, in plan view, and FIG.4A is a view according to the section along the line IV-IV of FIG.4. FIG.l shows a section of a cable car system with a support cable -1, on which by means of a traction cable 2, a vehicle 3 is moved. The vehicle 3 is formed with a chassis 31 on which there are two rockers 32, on which eight rollers 33 are mounted. The chassis 31 is moved by means of the pull cable 2, wherein the rollers 33 roll on the support cable 1. To the chassis 31, a support rod 34 is articulated, at the lower end of which is a cable car cabin 35.
    Some or all rollers 33 are formed with electric generators, through which electrical current is generated by the movement of the chassis 31 along the support cable 1. The voltage and the frequency of the electrical current generated thereby by the individual generators depend on the design of the generators and on the rotational speeds of the rollers 33. The outer diameter of the rollers 33 may be different in size due to manufacturing tolerances and due to different wear.
    Due to different outer diameters, through which different rotational speeds occur and due to different running properties of the rollers 33 is thus generated by the electric generators current with different voltages and different frequencies.
    To the generators located in the rollers 33 lines 36 are connected, which are guided along the support rod 34 to a distribution box 37. The outputs of the storage box 37 are connected to an AC / DC converter circuit 4 located in the cable car cabin 35 in which the current generated by the individual generators is rectified and converted to a predetermined voltage. The output of the AC / DC converter circuit 4 is placed in a distribution circuit 5, by which the supply of located in the cable car cabin 35 electrical consumers, such as a lighting system, a sound system, screens, heaters and telecommunications equipment or a battery with electrical Energy is controlled. The cable car cabin 35 is further formed with a transmitting or receiving antenna 38.
    As will be explained below with reference to FIG. 2, the AC / DC converter circuit 4 includes a plurality of AC / DC converters 41, 42, 43... 4n to which the outputs of the rollers 33 are located Generators Gl, G2, G3 ... Gn are guided. The AC / DC converters 41, 42, 43... 4n are each formed with two outputs, which are laid via a common bidirectional control line 47 and via a common measuring line 48 to a control unit 40 through which the AC / DC converters 41, 42, 43... 4n are controlled so that the DC electric current supplied from the individual AC / DC converters 41, 42, 43... 4n has the same predetermined voltage. The controller 40 is formed with an input and output line 40a. The current delivered by the AC / DC converter circuit 4 via the measuring line 48 to an output line 49 is conducted to the electrical consumers or to a battery.
    The design of the AC / DC converters 41, 42, 43... 4n is explained below with reference to FIGS.
    The three phases of the current generated by one of the generators G are applied via a line 51 to a rectifier 52, by which the AC output from the generator G is converted into a corrugated DC. The direct current output by the rectifier 52 is delivered via a line 52a to a DC / DC voltage converter 53, in which the voltage of this direct current is converted to a constant predetermined value. The DC power supplied from the DC / DC voltage converter 53 is supplied to the loads via the output line 53a.
    To the output line 51 of the generator G, a voltage and frequency transmitter 54 is connected, by which the voltage and the frequency of the output current from the generator G are determined. To the output line 53a, a current transmitter 55 and a voltage transmitter 56 are connected. Furthermore, the stator winding of the generator G is assigned a temperature sensor 57.
    In addition, a control circuit 58 is provided, to which the outputs of the voltage and Frequenzmesswertgebers 54, the current transmitter 55, the Spannungsmesswertgebers 56 and the temperature sensor 57 are applied. By means of this control circuit 58, the DC / DC voltage converter 53 connected via a control line 58a is monitored or controlled in such a way that the current delivered via the output line 53a has the predetermined constant voltage. The output lines 53a are connected to the output line 49 shown in FIG. The control circuit 58 is formed with a further line 59, which connects to the bidirectional control line 47 shown in FIG.
    As shown in FIGS. 4 and 4A, the AC / DC converter circuit 4 is constructed as a unit 6 having a frame 60 in which modules 61, 62, 63... 6n are inserted, on which the AG / DC converters 41, 42, 43 ... 4n are located. The modules 61, 62, 63 ... 6n are formed with gripping strips 61a, 62a, 63a ... 6n. The connection of the unit 6 to the distributor circuit 5 by means of a multi-pole line 39, via which the rectified and the predetermined constant voltage having current is delivered to the consumer or to at least one energy storage.
    The assembly 6 is further formed with contact strips 7, which are the modules 61, 62, 63 ... 6n assigned. In addition, the assembly 6 is provided with LED lights 8. Furthermore, the assembly 6 is formed with the transmitting or receiving antenna 38.
