SPOL2T-550/3150型隔离开关的检修及维护

Repair and maintenance of SPOL2T-550/3150 isolating switch

高压隔离开关具有明显的分断间隙,因此它主要用来将高压配电装置中需要停电的部分与带电部分可靠地隔离,以保证检修工作的安全。隔离开关用来进行电路的切换操作,以改变系统的运行方式。同时,也可以用来操作一些小电流的电路。隔离开关没有灭弧装置,不能用来切断负荷电流或短路电流,因此它通常与断路器配合使用。

High voltage isolation switch has obvious breaking gap,so it is mainly used to be part of the live parts of high voltage electrical installations blackout reliably isolated to ensure the safety of the maintenance work.The isolation switch is used for circuit switching operation to change the mode of operation of the system.Also be used to operate the small current circuit.The isolation switch None interrupter means can not be used to cut off the load current or short circuit current,so it is usually used in conjunction with the circuit breaker.
