METHOD FOR CHECKING THE IMPLEMENTATION OF THE SHUNT MODE OF OPERATION OF THE ELECTRIC TRACK CIRCUIT Russian patent published in 2023 - IPC B61L1/02 G01R27/02 

FIELD: railway machinery.

SUBSTANCE: checking the sheet operation of track circuits. Outside the operating conditions, in the absence of a variable obstacle in the form of a track circuits or a break in one place of one rail, within the limits of the operational length of the considered track circuit, a simulation resistance is connected to the input of the line of the cable supply end of the track circuit, equivalent to the imposition of a standard shunt in the limits of the operational length of the track circuit. The voltage at the output of the equipment of the supply end of the track circuit is measured and recorded when the simulation resistance is connected and the voltage at the input of the track receiver when the simulation resistance is connected. Next, the simulation resistance is turned off and during the operation of the electric track circuit, while being within the operational length of the track circuit of a variable obstacle in the form of a railway rolling stock, the voltage at the input of the track receiver is measured and recorded at the actual value of the resistance of the train shunt and the value of the actual supply voltage of the track circuit when in the boundaries of the operational length of the track circuit of a variable obstacle in the form of railway rolling stock. The sensitivity factor to the normative shunt is calculated as the ratio of the voltage at the input of the track receiver when the normative shunt is applied to the voltage at the input of the track receiver at the actual value of the resistance of the train shunt, at which the shunt mode of the track circuit is performed. The implementation of the shunt mode of the track circuit operation is determined in the case when the voltage at the input of the track receiver when the simulation resistance is turned on is greater than the voltage at the input of the track receiver when a variable obstacle in the form of railway rolling stock is within the operational length of the track circuit. Calculate and record the sensitivity factor to the standard shunt as the product of the ratio of voltage at the track receiver when the standard shunt is applied to the voltage at the track receiver when the actual shunt is applied and the ratio of the standard supply voltage at the output of the equipment of the supply end of the track circuit to the actual supply voltage of the track circuit at the output of the equipment supply end of the track circuit.

EFFECT: automation of remote control of the execution of the shunt mode of the electric track circuit.
