Abstract: The DC circuit breaker controller is developed based on the breaking principle of current transfer DC circuit breaker to meet the control requirement of DC circuit breakers. Detailed the analysis of the function and working principle of DC circuit breaker and controller, the modular design scheme is developed. The test platform build DC circuit breaker proves the feasibility of the scheme through test. The response time of the control equipment is less than 500 μ s, which provides guarantee for the current transfer of the DC circuit breaker and the disconnection of the whole machine.
Key words: DC circuit breaker; controller; modular design scheme; test platform
