Explosion-proof voltage transformer cabinet
The invention discloses an explosion-proof voltage transformer cabinet, and relates to the technical field of voltage transformer cabinets, the explosion-proof voltage transformer cabinet comprises a switch door, and the switch door is provided with a common coded lock and a reinforced coded lock; an upper pressure relief box is further included, an air bag only communicated with the interior of the PT cabinet is installed in the upper pressure relief box, the air bag is in a contraction state in the initial state, and a pressing switch is further installed in the upper pressure relief box and electrically connected with the reinforced coded lock. When the air pressure in the PT cabinet rises to enable the air bag to expand to a preset position in the upper pressure relief box, the pressing switch is contacted to electrify the reinforced coded lock, and the reinforced coded lock is in a working state at the moment; in the invention, the problem of insufficient door opening and closing stability of the PT cabinet during explosion is solved by using the common coded lock and the reinforced coded lock, the trouble in normal application can also be avoided, and meanwhile, the fire extinguishing can be automatically triggered, so that on one hand, deflagration can be avoided, and on the other hand, the fire can be extinguished as quickly as possible to reduce loss.
本发明公开了一种防爆电压互感器柜，涉及电压互感柜技术领域，包括开关门，所述开关门上安装有常用密码锁和加固密码锁；还包括上部泄压箱，上部泄压箱内安装有仅与PT柜内连通的气囊，初始状态时气囊处于收缩状态，上部泄压箱内还安装有按压开关，按压开关与加固密码锁电连接，当PT柜内部气压上升使气囊在上部泄压箱的内部膨胀至预定位置时接触到按压开关使加固密码锁通电，此时加固密码锁处于工作状态；本发明中，利用常用密码锁和加固密码锁，解决了爆炸时PT柜的开关门稳定性不足的问题，也能够避免正常应用时的麻烦，同时可以自动触发灭火，一方面能够避免爆燃，另一方面能够尽量快速地灭火以减少损失。
