Traction return balance device and method for railway electrification section

Abstract

The invention discloses a traction return balance device and a method for railway electrification sections. The traction return balance device includes an unbalanced test module and an impedance adjustment module; the unbalanced test module is connected to both ends of the traction coil of the choke transformer, and the impedance adjustment module is connected between the steel rail and the traction coil of the choke transformer; the unbalanced test module collects The traction return in the rail, analyze the sampling data, display the unbalance of the traction return and the impedance adjustment suggestion; the impedance adjustment module adjusts the impedance according to the impedance adjustment suggestion to minimize the unbalance. The invention can realize the balance adjustment of the rail traction return flow in the railway electrification section, reduce the unbalance degree of the rail traction return flow without affecting the smoothness of the rail traction return flow, and improve the working reliability of the track circuit and the vehicle-mounted equipment.

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
