Problems solved by technology

Its main disadvantage is: in the closed state, the fork-shaped static contact has a certain clamping force on the circular metal cap. When the fuse in the fuse tube is blown or the gate is opened, the clamping force will cause the fuse tube to fail. Flexible, reliable drop

Abstract

The invention relates to a remote-controlled straight-running dropout fuse with a lock, which includes a high-voltage insulating support, a fuse tube, a high-voltage terminal, a driving mechanism, and a control mechanism. One guide rail, the installation direction of the guide rail is parallel to the fuse tube, the middle of the hanging socket is slidingly connected with the guide rail, one end of the hanging socket is hinged with the lower end of the push-pull rod; the upper end of the push-pull rod is fixedly connected with the drive shaft of the driving mechanism, and the drive shaft is on the axis of the push-pull rod Linear movement in the direction; the static contact adopts metal elastic sheet. It has the advantages of small drop resistance of the fuse tube, flexible and reliable opening, etc., and is suitable for the protection switch of the high-voltage line of the power transformer.

Description

technical field [0001] The invention relates to a dropout fuse, in particular to a wireless remote control dropout fuse. The invention is suitable for the protection switch of the high-voltage line of the power transformer. Background technique [0002] A high-voltage drop-out fuse is installed between the high-voltage line of the power grid and the transformer, which is convenient for the maintenance and repair of transformer equipment and lines or the needs of power limitation. Ordinary high-voltage drop-out fuses are generally connected by high-voltage porcelain bottles, fuse tubes, and high-voltage switches. When using a special high-voltage insulating rod, it is necessary to manually push it up or down. The operator needs to wear insulating boots and gloves during work. The operation is cumbersome and prone to safety accidents. security incident. For this reason, Chinese Patent Publication No. is CN2456308 wireless remote control and manual dual-use drop-out fuse, dr...
