Method and apparatus for fusing electrical power equipment enclosed in a tank and surrounded by insulating fluid

摘要

A vacuum fuse is mounted in an insulating oil filled tank containing electrical apparatus and is directly immersed in the insulating oil. A fuse ferrule contact block is suspended in the insulating oil. The suspension for the contact block permits insulating oil to contact the contact block over its entire surface. An opening in the tank top large enough to accommodate the fuse is located adjacent the contact block. One ferrule of the fuse is provided with a cylindrical extension to contact the contact block. The other ferrule is provided with an extension on which is mounted a bushing well and a cover plate.
