Abstract

The invention relates to an auxiliary ground switch component. The auxiliary ground switch component of fuse comprises a ground switch electrically connected with the fuse, and an insulated base body which is used for fixedly sealing the ground switch; the external surface of the insulated base body is coated with a ground layer; the front end of the insulated base body is provided with a connection portion containing chamber; the ground switch comprises a long conductive rod, a ground connecting rod, an elastic insulated plunger, a ground end cap and insulated connecting rod, wherein the long conductive rod is electrically connected with a wire outlet end of the fuse and the front end of the long conductive rod is connected with the rear end of the connection portion containing chamber, the ground connecting rod is inserted in the connection portion containing chamber and is movably inserted in the long conductive rod, the elastic insulated plunger is sleeved on the ground connecting rod, the ground end cap is located at the external port of the connection portion containing chamber, and the insulated connecting rod is movably inserted in the ground end cap and the elastic insulated plunger, and the insulated connecting rod is fixedly connected with the ground connecting rod. The purpose of the invention is to provide an auxiliary ground switch component which is simple in structure and credible in work, so as to ensure that the wire outlet terminal of the fuse is grounded during examining and repairing the switch equipment, thereby guaranteeing the safety of examining and repairing.

Description

technical field [0001] The invention relates to a fuse auxiliary earthing switch assembly. Background technique [0002] In recent years, the miniaturization of switchgear is a research hotspot in the industry. At present, most of the domestic 10kV switchgears are made of fixed modules connected by busbars, and the air distance is strictly implemented according to 125mm, so the cabinets are large in size and the use environment is also limited; while most of the miniaturized switchgears use the air-filled cabinet solution to meet the reduction of phases And the relative insulation distance. Since the charged SF6 gas is a greenhouse gas, it is not a promotional product. In order to make up for the shortcomings of SF6 inflatable cabinets such as greenhouse effect and easy air leakage, as well as the shortcomings of large footprint of air-insulated switchgear. At present, it is necessary to develop a new type of switchgear, which can not only meet the requirements of miniatu...
