第二章安全操作 (二十四) 高压隔离开关,为什么不能带负荷操作? 隔离开关只是为了检修时,可靠地起断开电源的作用。它本身没有消弧装置,不能用于切断或闭合负荷电流,否则,将会产生大量电弧,造成弧光短路爆炸事故。这类误操作事故,曾多次发生,要引起严重注意。防止办法一是严格执行操作规程,二是装设断路器与隔离开关之间的机械或电气联锁装置。 (二十五) 母线隔离开关与出口隔离开关有无一定操作顺序?为什么? 有一定操作顺序。送电时,应先合上母
Chapter II Safety Operation (24) High-voltage disconnecting switch, why can not load operation? Isolating switch is only for maintenance, reliable disconnection of the power supply. It does not have arc suppression device itself and can not be used to cut off or close the load current. Otherwise, a large number of arcs will be generated, causing arc short-circuit explosion. Such misoperation accidents have occurred many times and cause serious concern. First, to prevent the implementation of strict operating procedures, the second is installed between the circuit breaker and isolation switch mechanical or electrical interlocking device. (Twenty-five) bus isolation switch and exit isolation switch have a certain order of operation? Why? There is a certain order of operation. When sending electricity, should close the mother first
