电力系统直流断路器短路级差配置研究

摘要

In power system,the requirements of selectivity and reliability on DC circuit breaker in direct power system are very high.On the basis of the short circuit differential configuration of three-sectional DC circuit breaker,this paper do the theory analyses%电力系统用直流电源系统中直流断路器的选择性、可靠性有着极高的要求。文中选取了三段式直流断路器短路级差配合进行理论分析以及试验验证,探索三段式直流断路器在实际电力系统中应用的可行性。
