摘要
以中性点不接地供电系统漏电保护作为研究对象,阐述了选择性漏电保护的概念及其重要意义;指出零序方向型选择性漏电保护的理论依据,即故障支路和非故障支路零序电流的大小和方向均不同;给出用单片机实现零序方向型选择性漏电保护的方法。
Take the electricity leaks protection which in the middle point ungrounded electric power system as researched object. explains the concept and the important meaning of alternative electricity leakage protection ; points out the theoretical foundation of zero directional alternative electricity leakage protection ,it means that the trouble branch road and distrouble branch road’s zero sequence current has different size and direction ;while it also gives the method of realize this kind of zero sequence directionaa alternative electricity leakage protection with single-chip computer.
