Description

Technical Field

[0002] A high-voltage drop-out fuse is installed between the high-voltage line and the transformer of the power grid to facilitate the maintenance and overhaul of transformer equipment and lines or the need for power restriction. Ordinary high-voltage drop-out fuses are generally composed of a high-voltage porcelain bottle, a fuse tube, and a high-voltage switch wiring. One end of the fuse tube is movably connected to the porcelain bottle high-voltage switch wiring, and the other end is connected to the porcelain bottle through a fuse movable hook ring. When opening the switch, a special high-voltage insulating rod needs to be used to manually pull it down. Operators need to wear insulating boots and insulating gloves during work. The operation is more troublesome and prone to safety accidents, especially when operating in bad weather such as rainy days. Personal safety accidents are very likely to occur. For this reason, intelligent drop-out fuses came into being. Intelligent drop-out fuses are generally fixed to the bracket at the use location by bolts. Workers need to carry tools such as wrenches to operate each time they are installed, which is inconvenient to install. Utility Model Content
