ABSTRACT:
A capacitor is electrically disabled to limit internal pressure buildup by attaching its electrical terminals to a first wall portion that bulges in a predetermined direction under internal pressure, providing electrical connections between the terminals and the capacitive element, and associating with a second wall portion (that does not move in the predetermined direction under internal pressure) a disconnect means such that when the first wall portion bulges, the terminals exert a force in the predetermined direction on the connections, which are then severed by a resisting force exerted by the disconnect means.
In another aspect, reconnection is prevented by having each electrical terminal connected by a conductor via a predefined pathway to the capacitive element, and providing means for blocking the pathway following disconnection.
