摘要
阐述了断路器选择性保护的概念和选择性保护的基本条件和具体条件。分析了典型配电系统中各种配电电器之间保护特性的选择性配合以及断路器与电动机过电流保护特性的配合。
In order to upgrade power supply quality and reliability of low voltage power distribution system, based on the selective protection concept of circuit breaker, the foundamental condition and actual condition and the typical protection characteristic of power distribution system were discussed.
