Abstract
Low voltage power capacitor of the self-healing type, wherein each capacitor cell is fitted with individual protection, enabling the cell to be disconnected in all cases of faults which are liable to occur. The cell coil is electrically connected in series to a fuse housed in a chamber arranged in the sealing cover of the casing housing the coil. Protection against overpressures inside the casing is provided by a membrane, deformation of which actuates a short-circuiting contact. The clean short-circuit, generated by closing of the short-circuiting contact, causes the fuse to blow and the faulty cell to be disconnected.
