Load isolation switch for live-line locking and false closing prevention

The invention provides an electrified locking anti-misoperation load isolation switch. An isolation switch operating handle (1) is provided with a handle jack (11) for an anti-misoperation bolt (2) to perform anti-misoperation locking; the action of the anti-misoperation bolt (2) is controlled by the anti-misoperation device control circuit board (5); the anti-error bolt (2) is screwed and fixed on a screw rod of the bolt driving motor (4) and is driven by the bolt driving motor; and the bolt driving motor (4) is connected with an output port of the anti-misoperation device control circuit board (5), and the motor is driven to perform pushing and pulling-back actions by virtue of forward current and reverse current output by the control circuit board, so that locking and unlocking of the isolating switch by the anti-misoperation bolt (2) are realized. 本发明提出一种带电闭锁防误合的负荷隔离开关，隔离开关操作手柄（1）上设有手柄插孔（11）供防误插销（2）进行防误闭锁；所述防误插销（2）的动作由防误装置控制电路板（5）控制；所述防误插销（2）旋紧固定在插销驱动电机（4）的丝杆上，依靠插销驱动电机驱动进行；所述插销驱动电机（4）连接防误装置控制电路板（5）的输出端口，依
