This invention relates to electrical circuit control devices and is intended to automatically troubleshoot electrical, locomotive circuits.

The purpose of the invention is to increase the speed of fault detection.

The drawing shows a schematic diagram of a device for monitoring electrical circuits of a locomotive.

The device contains control relays 1 with contacts 1.1, 1.2, 2 with contacts 2.1,2.2, 3 with contacts 3.1, 4 with contacts 4.1, 4.2, 4.3, relays 5 with contacts 5.1, 5.2, relays 6 with contacts 6.1, relays 7 s contacts 7.1, 7.2 and relay 8 with contact 8.1. The control relays are connected to the device 9, the device 10c by the contact 10.1, the device 11 with the contact 11.1 and the contacts 12-17, included in the controlled electric circuits.

The device contains decoders .18-26 for the number of devices of controlled circuits, the outputs of which are connected to the indicator 27, and the inputs through the corresponding contacts of the controlling relays to the power supply 28.

The device works as follows.

The open circuit of the device 9 by the contact 10.1 may occur as a result of failure in the chains of the devices 10 or 11. In this case, it is necessary to automatically interrogate the control terminals a, b, c and d, e, g, g, 3 with the subsequent presentation of information about break (malfunction) of that part of the chain, which served as the initial cause of the break of the subsequent chains.

If contact 14 does not close and the monitored device 11 does not receive power. E, then contacts 11.1 in the power supply circuit of the monitored device 10 turn out to be open without receiving power this device is about 84432

Opens the contact 10.1 in the circuit of the controlled apparatus 9, as a result of which the latter is not switched on. Then, through the closed (operable) pin 15, the control relay 1 is supplied with the supply voltage. The control relay 1 turns on and switches its contacts. Since contact 10.1 is open, the control relay 2 does not receive power, and its contacts remain in their original state. Through the closed (operable) pin 16 and pin 1.2 receives power to the control relay A and switches its

5 contacts. Due to the fact that contact 11.1 is open, the control relay 5 does not receive power and remains in the off position. Through a closed (good) pin 17 and contact

0 4.3, the control relay 7 receives power and switches its contacts, while relay 8 remains in the off position, since contact 14 is open. As a result, power supply 28

5 through pins 1.1, 2.2, 4.2, 5.2, 7.2 and 8.1 receives power to the decoder 25. The signal from the decoder 25 is fed to the input of the indicator 27, which highlights the designation of the faulty device in this case, the designation of the contact 14.

In the case when the circuit of apparatus 9 does not work out due to the non-contact 10.1J belonging to the controlled apparatus 10, but the contacts 16, 11.1 and 13 are working (closed), the decoder 23 receives power from the source 28. In this case the indicator 27 lights up designation of the relay 6, which indicates its non-destruction (coil or contact).

The number of chains and control

5 clamps can be unlimited. A similar search method and fault information provided is convenient and practical.
