Problems solved by technology

[0006] Processes 1 and 2 require human operation and judgment, and there is no test circuit for the indicating circuit in process 2. If human operation errors and circuit indication errors occur, it may lead to a dangerous situation of live operation, which may cause the electrical equipment of the vehicle to burn out, or cause personal injury.

Abstract

The invention relates to an electric high-voltage conversion circuit for rail transit vehicles with a new electronically controlled structure and the electric operation is simpler than manual operation. A manual disconnector requires a certain amount of force to operate in order to ensure that the position of the disconnector is firm. It is difficult for a user with less strength to operate the manual disconnector. , tThe electrically isolated switch incorporates the state of the load circuit into the control circuit and enables unpowered operation on the control circuit. In the whole practical application, only the knob is operated, and the electric disconnector circuit with high-voltage interlock is provided. The operation of the disconnector circuit must be tested before the operation of the conversion circuit, so that the operation of the disconnector is more labor-saving and safer.

Description

technical field [0001] The invention relates to an electric high-voltage conversion circuit for rail transit vehicles, belonging to the technical field of rail transit. Background technique [0002] Rail transit vehicles are powered by electric boots during normal operation, and sometimes need to be powered by workshop power during workshop maintenance. In previous domestic projects, this process is: [0003] 1. Ground the power grid; [0004] 2. Confirm whether the power is completely cut off through the indicator light on the power supply network; [0005] 3. Switch the power receiving shoe position to the workshop power position by manually turning the switch; [0006] Processes 1 and 2 require human operation and judgment, and there is no test circuit for the indicating circuit in process 2. If human operation errors and circuit indication errors occur, it may lead to a dangerous situation of live operation, which may cause the electrical equipment of the vehicle to bu...
