电磁锁

针对电力设备的特点，提出了用信号作电源的想法，解决了某些高压柜内没有二次电源的问题，通过分析试验，能驱动电磁锁等装置。

According to the feature of power equipment , an idea , using signal instead of power source to settle the problem without secondary power source in some HV switchgear cubicles , is put forward . Through experiment analysis , it can drive the appliance of electromagnetic lock .

基于自锁原理的磁悬浮飞轮电磁锁紧机构电动门锁，电动窗+驾驶座自动上/下

Electromagnetic locking device based on self-locking for magnetic suspended flywheel Power door locks and windows with driver side one-touch up / down feature

给出了电磁锁的结构，该锁克服了普通电磁锁没有双向功能的缺点，并可自带电源。

The magnetic lock structure was given , the lock overcame the disadvantage of normal magnetic lock without dual functionality , it is own powered .

只要高压回路带电，电磁锁就处于闭锁状态，从而防止运行人员误操作，误入带电间隔。

Once the high-voltage circuit is in the status of voltage presence , electromagnetic locks are under locked , in order to prevent workers from misoperation or entering into charged spacing .

该高压带电显示装置无需外接电源，不仅可以反映回路的带电状况，而且还能与电磁锁实现有效地配合，实现强制闭锁开关手柄、阀门等电气操作。

This high-voltage presence indicating device without external power supply , not only reflects the charged status of circuit , but also could be coordinated with electromagnetic locks effectively , so that electrical operations , such as mandatory locking switch handles and valves , can be achieved .
