Description

The invention relates to railway transport, in particular, to devices for monitoring electric circuits controlling subway cars. The purpose of the invention is to increase the safety of the service. The drawing shows a schematic circuit diagram of a device for monitoring circuits controlling an electric rolling stock of direct current. The device contains on each car a blocking relay, the coil 1 of which is connected by me y1; for an additional train wire 2. and the minus terminal of the on-board power source, the supply contactor to the car 3 control circuit of the traction drive of the car, one terminal of coil 4 of which is connected to the minus terminal the on-board source and the voltage control relay in the contact network, the coil 5 of which is connected through the current collectors 6 to the contact network, which through the disconnector 7 is connected to the power circuit 8 of the car. Additional train wire 2 through closure contacts of 9 buttons, located. The jack on the head cars is connected to the train wire 10 connected via pin 11 to the positive terminal of the on-board power source. Another output of the coil 4 of the power supply contactor to the control circuits 3 through the following: mykulyatsiya contact 12 voltage control relays in the contact network, shunt-close contact 13 of the blocking relay, is connected to the train propod 10, to which the control circuits 3 are connected via the closing pin 14 . The device works as follows. When checking the electrical control circuits in the depot with a traction drive of an electric rolling stock 82, the driver is installed (not shown) in the driver's position, and the closing contact 11 and: train: is frozen: the wire 10 is connected to the positive terminal of the on-board power source. the button of the latching contact 9 and the coil 1 of the blocking relay through an additional train wire 2 is connected to the onboard power source. The closing contacts 13 are closed and blocking the closing contacts 12 of the control relay voltage at this contact seti.Pri 4 contactor coil power supply to the control chains are connected to the positive terminal of the onboard power source 14 and make contacts connect the control circuit 3, the traction drive to the composition; the positive conclusion of the onboard power supply, power supply. The closure of the control circuits is determined by a test lamp (not shown) in the power circuit of which the contacts of the driver controller and the auxiliary contacts (not shown) of the linear contactors used in the power circuits of the 8 cars are included. At the first moment, when voltage is applied to the 3 control circuit of the motor driven control lamp, the lamp lights up, and then when the circuit is properly assembled, it goes out. If the traction drive control circuits 3 are not assembled correctly, the control lamp continues to light, indicating a failure in the operation of the traction drive control circuits 3. The use of the proposed device makes it possible to increase the safety of servicing an electric rolling stock by eliminating the supply of voltage to the car from an auxiliary power source and eliminating the possibility of the rolling stock being set in motion during inspections in the operative depot of electric traction drive control circuits.
