Passive electromagnetic interlocking device
The invention relates to the technical field of electrical equipment, and discloses a passive electromagnetic interlocking device. The anti-theft lock comprises a lock body, a lock head, a microswitch, a limiting part, an electromagnet, a voltage monitoring control module and a state indicator lamp module. When the first end of the limiting part is close to the lock head, the second end of the limiting part is far away from the microswitch, and when the first end of the limiting part is far away from the lock head, the second end of the limiting part is close to the microswitch. The voltage monitoring control module is directly connected with the high-voltage side, a secondary power supply is not needed for work, the cost is reduced, whether the power supply of the high-voltage side is turned off or not can be monitored, and the lock head can be limited to slide in the first direction under the condition that the high-voltage side is electrified in cooperation with the limiting part, the microswitch and the electromagnet; and only under the condition that the high-voltage side is powered off and the electromagnet is not powered on, the lock head can be moved to realize unlocking, so that an operator is prevented from operating under the electrified condition, and the safety and the reliability are effectively improved.
本发明涉及电气设备技术领域，公开了一种无源电磁联锁装置。本发明包括锁体、锁头、微动开关、限位部、电磁铁、电压监测控制模块及状态指示灯模块；限位部的第一端靠近锁头时，限位部的第二端远离微动开关，限位部的第一端远离锁头时，限位部的第二端靠近微动开关。本发明利用电压监测控制模块直接与高压侧相连，无需提供二次电源进行工作，降低成本，而且还能监测高压侧电源是否有关闭，配合限位部、微动开关以及电磁铁，则可以限制锁头在高压侧带电情况下无法沿第一方向滑动，进而无法实现接受，仅在高压侧断电情况下，电磁铁不得电，才能够移动锁头以实现解锁，避免操作人员在带电情况下进行操作，有效地提升安全性和可靠性。
