Abstract

The invention belongs to the technical field of power distribution equipment, and discloses a direct-acting three-station isolating switch moving contact rotation stopping and positioning device for a gas-insulated switchgear, which comprises an isolating contact bracket, and a switching-on contact bracket and a grounding contact bracket which are arranged on the two sides of the isolating contact bracket, the isolation contact support, the connection contact support and the grounding contact support are all of tubular structures, and the three supports are all provided with fixing faces. A lead screw is arranged between the connection contact support and the grounding contact support, a moving contact is sleeved on the lead screw, and the lead screw penetrates through a pipe cavity of the isolation contact support. The device is simple in structure, good in reliability and low in cost.

Description

technical field [0001] The invention belongs to the technical field of power distribution equipment, and relates to a positioning device, in particular to a fixed-rotation positioning device for a moving contact of a direct-acting three-position isolating switch for an inflatable cabinet. Background technique [0002] With the continuous advancement of science and technology, human beings have higher and higher requirements for power distribution products. Green environmental protection, energy saving, intelligence, maintenance-free, high reliability and low cost have become the development direction of switchgear. In this context, inflatable Cabinets have become one of the main development directions. [0003] The existing inflatable cabinet direct-acting three-position isolating switch moving contact stop rotation is mostly a strip-shaped insulating block fixed structure, which is large in size and low in strength. It directly affects the insulation performance and the ov...
