Abstract

The invention discloses a three-position isolating-grounding switch. The three-position isolating-grounding switch comprises a moving end conductor, an grounding insulator, a grounding contact, a sliding contact, a static end conductor, a static end contact, a casing and a transmission rotary shaft. The grounding contact, the sliding contact and the static end contact are arranged on the same axis in sequence. The grounding contact is installed on the casing through the grounding insulator, the static end contact is connected with the static end conductor, the sliding contact is connected with the moving end conductor, and the static end conductor and the moving end conductor are respectively fixed on the casing and are insulated. A rack is embedded into the sliding contact, the transmission rotary shaft is provided with a gear matched with the rack, can drive the sliding contact to perform straight-line reciprocating motion along the axis, enable the sliding contact to be connected with the grounding contact or the static end contact, and can be not contacted with the grounding contact and the static end contact at the middle position. The three-position isolating-grounding switch achieves mechanical interlocking and improves the reliability.

Description

technical field [0001] The invention relates to the technical field of power transmission and distribution, in particular to an isolation-earth switch device. Background technique [0002] At present, the isolating switch and the grounding switch for 126kV gas-insulated metal-enclosed switchgear adopt a split structure, and two mechanisms are required to drive the isolating switch and the grounding switch respectively. Electrical interlocking is adopted between the grounding switches. The original isolating and grounding switch main circuit and grounding circuit are electrically connected using plum blossom contacts or self-supporting contacts. The contact size is large, the conductivity is not high, and the size of the isolation-grounding switch module is difficult to control. Contents of the invention [0003] The invention aims to provide a three-position isolating-grounding switch, which realizes the mechanical interlocking of the isolating-grounding switch, improves ...
