Abstract

A fuse housing assembly having a fuse holder housing for receiving a fuse holder. The fuse housing is mountable to a transformer tank that holds a dielectric liquid. When the fuse holder and fuse are inserted into the fuse housing that is mounted to the transformer tank, the fuse is located under the dielectric oil. The fuse holder assembly includes a vent tube that communicates a gas above the level of the dielectric liquid in the transformer to the interior of the fuse holder housing. When an operator removes the fuse holder to replace an exhausted fuse, a seal formed between the fuse holder and the fuse holder assembly is broken, and pressurized gas within the transformer tank will vent through the vent tube, through the interior of the fuse holder housing, and out an open end of the fuse holder housing to atmosphere, rather than causing the dielectric liquid to flow out of the fuse holder housing.
