Embodiment Construction

[0025] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] The GIS isolating switch of the present invention is taken as an example of a gas-insulated and enclosed isolating switch. Of course, the GIS isolating switch claimed in the present invention is not limited to the gas-insulated and enclosed isolating switch described in this embodiment, and can also be other high-voltage switches, such as ordinary Or quick isolating switch, isolating earthing switch, other three-position isolating earthing switch or even vacuum circuit breaker, etc.

[0027] The gas-insulated hermetic isolating switch in this embodiment is as Figure 1~2 As shown, it specifically includes a sealing cylinder 9, and an insulator 1 is fixedly installed at the end of the sealing cylinder 9. The insulator is a relatively common basin-type insulator. Of course, in other embodiments, it can also be an insulator of other forms, and It is...

Abstract

The present invention provides a fixed contact and a fixed contact module, and a GIS isolation switch. The fixed contact module comprises a fixed contact and an arcing contact, the fixed contact comprises a hollow contact seat, one end, in an axial direction, of the hollow contact seat is provided with an opening configured to allow a moving contact to plug, the other end of the hollow contact seat is provided with a fixed connection structure connected with an insulator, the inner cavity of the hollow contact seat is provided with an installation support, and the arcing contact is installed on the installation support and is extended into the opening. According to the design of the structure, the fixed contact module only needs connection of the fixed contact and the insulator with no need for preservation of a connection position of the arcing contact on the insulator so as to reduce the size of an insertion piece on the insulator; and moreover, the arcing contact is installed on thefixed contact to shorten a distance between the arcing contact and the plugging position, the breaking of the arcing contact is not easy to happen, and the reliability is high.

Description

technical field [0001] The invention relates to a static contact, a static contact assembly and a GIS isolating switch using the static contact assembly. Background technique [0002] With the continuous improvement of high-voltage and ultra-high voltage transmission requirements, GIS equipment has been more and more widely used. The static contact assembly used in the GIS isolating switch mainly includes the main contact used for flow through and the arc contact used for starting arc. On the insulator, the main contact is cylindrical and one end is fixed on the pot insulator, and the arc contact is located in the main contact. This traditional installation method requires a large size of the pot insulator insert, and the long screw rod makes the arc contact's moment arm large, which has the risk of breaking and low reliability. Contents of the invention [0003] The purpose of the present invention is to provide a static contact assembly with simple structure and reliab...
