Traction return current balancing device and method for railway electrified section

Abstract

The invention discloses a traction return current balancing device and method for a railway electrified section. The traction return current balancing device comprises an unbalance testing module and an impedance adjusting module. The unbalance testing module is connected to two ends of a choke transformer traction ring, and the impedance adjusting module is connected between a steel rail and the choke transformer traction ring. The unbalance testing module collects the traction return current in the steel rail, analyzes the sampled data, and displays the unbalanced degree of the traction return current and impedance adjustment advises. The impedance adjusting module adjusts the impedance according to the impedance adjustment advises to minimize the unbalanced degree. By the aid of the device, balance adjustment of the steel rail traction return current in the railway electrified section can be implemented, on the premise that the smoothness of the steel rail traction return current is free of being influenced, the unbalanced degree of the steel rail traction return current is reduced, and operating stability of a track circuit and vehicular device.

Description

technical field [0001] The invention relates to a traction return balance device used in railway electrification sections, and also relates to a traction return balance method based on the device, which belongs to the technical field of railway signals. Background technique [0002] The railway is the lifeblood of national transportation, and the railway signal system is the system for commanding and controlling the operation of trains, and is the key equipment to ensure the safety and efficient and orderly operation of railway transportation. In the railway signaling system, the track circuit for checking section occupancy / vacancy is the key basic equipment of the entire signaling system, which is directly related to the safe and reliable operation of the signaling system. [0003] The electrified section of the railway is equipped with a traction substation, and the traction return current is sent to the catenary by the traction substation, and the train is connected to th...

AI Technical Summary

Problems solved by technology

In the curve area, because the outer rail wears more seriously than the inner rail, there are more conductive slag from the wear, which will inevitably reduce the resistance to the ground, causing the unbalanced traction return flow

Therefore, it is necessary to frequently clean up ballast and other work, which increases the workload

Second, there is blindness in the imbalance

Disturbances caused by traction return are still present and can even increase the unbalance of rail return
