TRAM SWITCH CONTROL DEVICE Russian patent published in 2025 - IPC B61L5/06 B61L7/08 

FIELD: railways.

SUBSTANCE: invention relates to remote control of switches drives of urban rail transport. Device comprises starting and blocking contactors, first, second and third relays, one input and two output shunt air contacts, two switch electric drives with solenoid coils, three resistors, capacitor, sensor of current passage through tram current collector, voltage converter and power supply source. On contact wire by two tram suspended clamps, input control section is selected, divided by third tram clamp into two equal sections, wherein the current passage sensor resistors are connected to the control section wire extreme terminals, and the third terminal and the sensor resistors connection point are connected to the inputs of the threshold element. Input air shunt contact is located at the middle point of the input control section of the contact wire. Voltage converter is connected to contact wire and to negative circuit, and its output is connected to input of power supply unit, output of which is connected to power supply circuits of current passage through current collector threshold element sensor.

EFFECT: high reliability of the device for controlling a tram switch and improved operational properties thereof.
