Abstract

The invention relates to a three-station isolation grounding switch, comprising a moving contact seat (3); an insulation rod (7) is rotationally provided on the moving contact seat; the insulation rod is provided with a power input end and a power output end provided with a gear (8); a moving contact (4) is movably and guidedly provided in the moving contact seat; the moving contact is fixedly provided with a rack (6) extending along a moving direction thereof and engaged with the gear; an installation chamber with the rack assembled therein is disposed in the moving contact; the power output end of the insulation rod penetrates into the installation chamber; the gear engages with the rack in the installation chamber; and the moving contact is provided with a long guiding hole (9) for guidedly matching the insulation rod along the moving direction. The three-station isolation grounding switch provides both the rack and the gear in the installation chamber, thus greatly improving the distribution of the electric field around the insulation rod, allowing for a small internal diameter of the housing of the isolation grounding switch.

Description

technical field [0001] The invention relates to electrical equipment, in particular to a three-position isolating grounding switch. Background technique [0002] There are two main transmission structures of the three-position isolation and grounding switches currently available in the market. One is the crank arm structure, which completes the three-position isolation and grounding function through the output angle of the crank arm. The other type is the rack and pinion structure, which drives the corresponding contacts to move through the gear drive rack, thereby completing the grounding function. For example, the Chinese patent application number 201010590477.1 discloses a three-position isolation grounding switch, the three-position isolation grounding switch includes a housing, a static contact, a moving contact, a moving contact seat, and a support seat, wherein the support seat Assembled in the inner cavity of the housing, the moving contact seat is fixedly assembled...
