摘要
配电系统故障防护难以实现是因为防护措施及断路器级间的配合都需要满足连续不等式。简要介绍了故障防护的重要性,分析了自动切断电源的故障防护措施的实施条件。通过实例介绍实施自动切断电源的故障防护的分析过程。
Fault protection in distribution systems is difficult to achieve because the four protection measures and the coordination between circuit breakers need to meet continuous inequalities.This paper briefly introduces the importance to fault protection,focuses on the implementation conditions of the fault protection measures of automatic power cut off,introduces the analysis process of implementing the fault protection of automatic power cut off through examples.
