摘要
在 6 .3kV配供电系统中 ,变压器中性点通过 381Ω电阻接地 ,以限制接地短路电流不超过 10A。该系统的继电保护设计 ,除了过电流保护外 ,每条供电馈线还配置了灵敏角为 0°的零序方向保护。讨论零序方向继电器的动作行为 。
In the 6.3kV power supply and distribution system,neutral point of transformer grounds through 381Ω to limit short circuit current not exceeding 10A. Protection relay system of shajiao B power station was designed by Toshiba JAPAN, except over current relay. Every power supply line has a directional ground relay with the sensitive angle of 0°.This paper discusses operative action of the directional ground relay, and analyzes the problems in the practical operations.
