摘要
为了解决高压交流真空断路器静触头在断路状态因遭到意外情况而发生短路情况出现,设计开发了一种无论断路器处于接通或断开的任何时候,都可以自动断路器静触头加以保护的装置。该装置利用扭簧储存能量后所具有的弹性恢复功能,实现了断路器闭合时保护装置离开静触头,断开时保护装置复位以保护静触头的作用。动作效果良好。
In order to solve the short circuit of the stationary off-state contact of the high-voltage AC vacuum circuit breaker due to un-foreseen events, designing a device to protect the stationary contact of automatic circuit breakers no matter breaker is turned on or off.The device uses the elastic recovery ability of the torsion spring with energy storage.The protection device will remove from stationary contact when contact breaker is closed, and reset when the breaker is turned off. It functions effectively.
