The utility model discloses a new type of explosion-proof device for capacitor, including an explosion-proof plug, an explosion proof sleeve and an elastic seal ring. A pressure relief block with a convex part is arranged in the body of the explosion stopper, and the pressure relief hole in the pressure relief block is connected with a vertical hole in the interior of the protruding part, and a folding cover plate is arranged at the lower end of the vertical hole, and the bottom of the explosion proof sleeve is arranged with a row pressure mouth. The top needle has the vent channel and the exhaust port, and the top needle passes through the sinking platform above the upper surface of the pressure relief cavity. The spring is set in the stroke cavity between the pressure relief block and the explosion proof sleeve. The top is set on the convex part of the pressure relief block through the top, and the bottom ring is supported on the pressure relief block on the opening of the pressure relief cavity and is located in the stroke cavity. A rotating limit block is set on the side wall. Through the above structure, when the pressure in the capacitor reaches or is greater than the maximum allowable pressure, the internal pressure will release the pressure to reduce the internal pressure of the capacitor and eliminate the hidden danger, thus avoiding the accident and improving the safety.

,尤其涉及一种新型电容器防爆装置。
技术介绍
电容器,顾名思义是一种存储电荷的器件,两块金属电极之间夹一层绝缘电介质,当在两金属电极间加上电压时,电极上就会存储电荷,所以电容器是储能元件。电容器在电路中的作用非常广泛,包括耦合、滤波、谐振、积分、微分等等,电力电容器在广泛应用于工厂配电系统、居民小区配电系统、市政商业建筑、交通隧道配电系统、箱变、成套柜、户外配电箱等各种情况下;现有的电容器都是固定封装式的结构,电容器在长时间使用的过程中,很容易产生热能,很容易产生自爆,从而导致在电容器周围的其他电子元器件被其损坏,从而损失大量的资源和成本,甚至使使整个系统瘫痪。
