Wound electrical capacitor with excessive pressure protective device

摘要

A wound electrical capacitor, particularly a power capacitor provided with an excess-pressure break-away structure employing a tubular shaped electric conductor which forms the electric supply line to the capacitor winding and which is disposed within the housing. The conductor has a predetermined break point at which it will break under a tension load applied to it over the housing bottom and a tensioning device, in the presence of an excessive pressure within the housing. The invention is particularly suitable for employment in oil-impregnated, regeneratable power capacitors.
