Abstract
A protection element for a capacitor with self-healing properties has a membrane for activating a current interruption element when a gas, produced when a self-healing operation occurs within the capacitor, exerts a pressure on the membrane, the current interruption element being connected in series with an electrode of the capacitor, the current interruption element interrupting an electrical current flowing towards the electrode when the pressure is exerted on the membrane, and the current interruption element being operationally engaged with a temperature sensitive member that reacts, when sensing a temperature above a predetermined value, in a manner to operate the current interruption element.
