摘要
Abstract
Due to the absence of a natural zero crossing point for direct current,it is more difficult to break the directt current compared to alternating current when a short circuit occurs.This article introduces a topology scheme of a medium voltage 10kV direct current circuit breaker based on the principle of magnetic coupling current transfer,which can achieve fast breaking of 15kA direct current.Firstly,the principle and control logic of DC circuit breakers are introduced.Then,based on the topology scheme,design ideas for core components such as fast mechanical switches,power electronic switches,and magnetic coupling devices are proposed.Finally,simulation analysis is conducted on the scheme based on the simulation model,and the disconnection conditions under different working conditions are simulated,thereby verifying the effectiveness of the scheme.关键词
