Liquid interrupter module

摘要

The invention provides a current interrupter employing a liquified dielectric medium such as sulfur hexafluoride to effect rapid arc extinction. A pump cylinder forces the dielectric liquid into the vicinity of a fixed contact. The pump cylinder is refilled from within the contact enclosure after each current interruption to allow for repeated operations. Check valves are provided for preventing any dielectric gas from entering the pump cylinder. The interrupter system further includes a pressure absorbing accumulator for smoothing pressure changes and a cooler for removing heat from the dielectric medium.
