    • 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.
    • 一种保险丝壳体组件,其具有用于容纳保险丝座的保险丝座壳体。 保险丝外壳可安装在保持电介质液体的变压器箱中。 当保险丝座和保险丝插入安装在变压器箱的保险丝外壳中时,保险丝位于电介质油下方。 保险丝保持器组件包括通气管,该通气管将变压器中的介电液体的高度之上的气体连通到保险丝座外壳的内部。 当操作人员移除保险丝座以更换耗尽的保险丝时,形成在保险丝座和保险丝座组件之间的密封件被破坏,变压器箱内的加压气体将通过通气管排出,通过保险丝座外壳 并且将保险丝座壳体的开口端从大气压出来,而不是使介电液体从保险丝座外壳流出。
