常规变电站无人值班改造遥控操作事故音响及重合闸的闭锁

Accident signal and recloser's lock in operation of remote control when transforming general substation into an unatfended one

常规方式变电站无人值班改造的一项内容是对所有断路器增加遥控操作功能。断路器遥控操作分闸与保护动作分闸过程的一个重要区别,是前者不允许有事故音响及重合闸启动,本文在此方面作了一些探讨,并提出了解决方案。

A task in transforming a general substation into an unattended one is to add remote control functions to all the circuit-breakers. An important difference between the tripping of CB controlled remotely and the tripping operated by protection is that the operation of the accident signal and recloser are not allowed in the former one.Some problems in this aspect are discussed and solutions are presented at length.
