    隔离开关 (Isolating switch)是一种主要用于“隔离电源、倒闸操作、用以连通和切断小电流电路”,无灭弧功能的开关器件。隔离开关在分位置时,触头间有符合规定要求的绝缘距离和明显的断开标志;在合位置时,能承载正常回路条件下的电流及在规定时间内异常条件(例如短路)下的电流的开关设备。一般用作高压隔离开关,即额定电压在1kV以上的隔离开关,它本身的工作原理及结构比较简单,但是由于使用量大,工作可靠性要求高,对变电所、电厂的设计、建立和安全运行的影响均较大。隔离开关的主要特点是无灭弧能力,只能在没有负荷电流的情况下分、合电路。词条介绍了隔离开关的功能、特点、类型、应用、防误改进、维护、常见问题等。
