Explosion-proof capacitor structure

The utility model provides an explosion-proof capacitor structure which resolves a problem that a metalized film capacitor has large loss and heavy heat generation, and causes accidents when being in failure because of incapability of timely cutting off power. The explosion-proof capacitor structure comprises a capacitor body. The capacitor body comprises a housing, a top cover, a core group, and a conductive pole with one end connected with the top cover. The conductive pole is provided with a weak structure. The cross section of the weak structure is less than the cross sections of other parts of the conductive pole and the weak structure is easy to fracture when bearing force. The other end of the conductive pole is connected with the core group. When air pressure in the housing reaches a preset value, the bottom of the top cover is plumped so as to drive the conductive pole to move. Then, the weak structure is fractured and all connection of the core group is in failure. A self-healing metalized polypropy
