Abstract

A capacitor assembly which positively disconnects failing capacitors is disclosed. This assembly will disconnect electrical power from a capacitor when internal pressure builds up inside the capacitor as a result of an internal short circuit. One or more capacitors are connected electrically into a circuit. Terminals are fixedly connected at each end of the capacitor. The protruding ends of the terminals slidably couple the capacitor to a source of alternating current (AC) power. The normal failure mode for capacitors is to develop internal short circuits. The failed capacitor then heats up rapidly and generates internal pressure. This pressure deforms the end portion of the capacitor. When the end of the capacitor moves in a longitudinal axis of motion, the slidable connection of the terminal is moved to a non-contacting position and the electrical connection is interrupted.
