| 摘 要： | 500kV系统变电站主接线大部分采用一个半断路器接线,一条出线对应两个开关,线路保护CT采用和电流,中间开关同时和两条出线有关联等。一个半断路器接线的复杂性主要体现在开关保护及自动装置的配合上,因此重合闸应用是一个较为复杂的问题。理清楚重合闸的原理和应用对500kV系统安全生产有着十分重要的意义。

| Abstract: | 500kV substation main connection adopts mostly a breaker and a half connection,which a outgoing line corresponds to two breaker,and mid-breaker relates simultaneously to two outgoing line,and current transformator of transmission line protection employs sum current.The complexity of a breaker and a half connection embodies mainly the coordination of breaker protection and automatic equipment,so the application of auto reclosing is a more complicated issue.Clearly understanding of the principles and application of auto reclosing circuit breaker in the 500kv power system has very important significance on safety in production. |
