摘要
Abstract
Aiming at the electromagnetic compatibility(EMC)problem of false triggering in the indirect high-speed release of DC circuit breakers in switchgear,this paper analyzes the operating principle of the indirect release and the mechanism of its EMC-induced false triggering.The research is carried out from three aspects:interference sources,conduction paths,and sensitive components.A comprehensive EMC improvement scheme is proposed,including overvoltage source suppression,optimized wiring layout,shielding and grounding,and filter installation.Field test results show that the scheme can effectively solve the false triggering issue of the indirect release of DC circuit breakers and significantly improve the electromagnetic compatibility performance of DC switchgear.The research results possess good engineering application value for ensuring the safe and stable operation of rail transit power supply systems.关键词
