直流断路器临界负载电流测试分析

Analysis on the Critical Load Current Test of DC Circuit Breaker

制定了临界负载电流测试方案。通过对直流断路器的临界负载电流测试及其燃弧时间的分析,提出了直流断路器应增加临界负载电流考核,以保证直流电路的安全可靠运行。经改进后测试,均能分断直流电流。

This paper formulated a scheme for critical load current test and analyzed the critical load current test and the arcing time of DC circuit breaker. It put forward that the DC circuit breaker should add the critical load current test in order to ensure the DC circuit work safely.
