Problems solved by technology

The existing breaking contacts of high-voltage switches are composed of moving contacts and static contacts. The static contacts are fixedly installed in the insulating cavity, and the moving contacts are hinged on the insulating pull rod. The relative movement speed of the moving contacts and the static contacts depends on Due to the movement speed of the insulating tie rod, in order to increase the breaking speed of the switch, only the moving speed of the insulating tie rod should be increased, which will greatly increase the production cost and then consume power. Impact force, affecting the service life of the equipment

Embodiment Construction

[0017] Such as figure 1 As shown, the UHV switch double-speed breaking contact of the present invention includes an insulating cylinder 7 and a static contact 3 arranged in the insulating cylinder 7, the static contact 3 and the insulating cylinder 7 are connected by a spring 2, and the static contact 3 There is a load static contact 5 on the contact surface with the moving contact 14, and the inner wall of the insulating cylinder 7 has a blocking step 21 for preventing the movement of the static contact 3. The static contact 3 has a disc-shaped static contact base with a through hole, the center of the static contact base has a columnar arc-extinguishing contact, and multiple load static contacts 5 are distributed around the base ; Correspondingly, the moving contact 14 has a disc-shaped moving contact base, the moving contact base has an arc blowing tube 4 that runs through it, and the upper end of the arc blowing tube 4 faces the arc extinguishing contact of the static cont...

Abstract

The invention includes insulating cylinder, fixed contact and moving contact set in the insulating cylinder. The fixed contact connects to insulating cylinder through spring connection. There are load fixed contact and arcing contact on interface of fixed contact and moving contact. The block step preventing fixed contact from moving is set on the inner wall of insulating cylinder. The fixed contact is designed into spring telescoping type for shortening the arc time when making breaking operation.

Description

technical field [0001] The invention relates to a double-speed breaking contact of an ultra-high voltage switch used in electric power equipment. Background technique [0002] All power equipment switches need to have breaking contacts. When used as high-voltage switches, the faster the breaking speed, the shorter the time, the better, because when the moving contacts and static contacts of high-voltage switches are close to each other, arcs are easy to occur, and the faster the breaking speed is, the better. The shorter the arcing time, the less damage to the equipment. The existing breaking contacts of high-voltage switches are composed of moving contacts and static contacts. The static contacts are fixedly installed in the insulating cavity, and the moving contacts are hinged on the insulating pull rod. The relative movement speed of the moving contacts and the static contacts depends on Due to the movement speed of the insulating tie rod, in order to increase the breaki...
