防爆電磁啟動器工作原理

防爆電磁啟動器是馬達的重要裝置, 旨在有效防止電弧引起的火災事故. It’s predominantly utilized for remotely controlling motor operations like start, 停止, 並反轉, 同時還可以防止低電壓和過載情況.

該啟動器包括一個沖壓外殼, 鋼底座, an AC contactor, and associated wiring. When the start button is activated, the coil in the AC contactor within the starter gets energized. This action connects the power supply by moving the contact group into place, maintained by a self-locking auxiliary contact. 反過來, hitting the stop button de-energizes the coil, causing the contacts to disengage and disconnecting the power supply.

Its robust and precise design makes it indispensable in hazardous areas, ensuring safe and controlled motor operations in potentially 霹靂 環境.
