Abstract

The invention discloses a fault processing method for a traction converter. The fault processing method comprises the following steps: acquiring a semi-intermediate voltage parameter of the traction converter, wherein the semi-intermediate voltage parameter comprises a semi-intermediate voltage amplitude and a semi-intermediate voltage frequency, and the semi-intermediate voltage is one half of the intermediate loop voltage of the traction converter; determining the fault type of the traction converter according to the semi-intermediate voltage parameter; and executing corresponding fault processing operation on the traction converter according to the fault type. According to the invention, the fault type of the traction converter can be accurately judged, and over-protection of faults isavoided. The invention further discloses a fault processing device of the traction converter, a fault processing system of the traction converter, a rail vehicle and a storage medium, which have the above beneficial effects.

Description

technical field [0001] This application relates to the technical field of locomotives, in particular to a traction converter fault handling method, a traction converter fault handling device, a traction converter fault handling system, a rail vehicle and a storage medium. Background technique [0002] The traction converter is one of the key components of the train. Its main function is to convert the electric energy between the DC system and the AC system, and then realize the starting, braking and speed regulation control of the AC traction motor. [0003] When a ground fault occurs in the traction converter, it is necessary to perform corresponding fault handling operations on the traction converter to reduce the impact of the fault. In the related art, no matter what kind of ground fault occurs in the traction converter, the VCB (main circuit breaker, Vacuum Circuit Breaker) is cut off according to the most stringent protection measures, the vehicle is stopped for inspe...
