Abstract

The invention discloses a gas insulated switch, which relates to the technical field of switch equipment and comprises a gas insulated switch body, a vacuum arc extinguish chamber, an annular cooling sleeve, a support ball, a water storage cavity, a mercury liquid cavity, an isolation cavity, a gas suction cavity and a second support rod. According to the invention, the annular cooling sleeve carries out annular heat absorption, cooling and heat dissipation treatment, the supporting balls can effectively enlarge the heat absorption range and improve the heat dissipation effect, air suction treatment can be carried out on the vacuum arc-extinguishing chamber, the vacuum degree of the vacuum arc-extinguishing chamber can be improved, and the working effect of the vacuum arc-extinguishing chamber can be improved; and the annular cooling sleeve can improve the arc extinguishing effect of equipment while enhancing the heat absorption, cooling and heat dissipation effects of the gas insulated switch body, the hemispherical block is tightly attached to the inner wall of the sealing ring for multiple sealing treatment, the sealing performance is guaranteed, leakage of the vacuum arc-extinguishing chamber is avoided, the suction treatment effect can be guaranteed, the stability of the vacuum degree of the vacuum arc-extinguishing chamber can be improved, and repeated fluctuation of the vacuum degree in the vacuum arc-extinguishing chamber is avoided.

Description

technical field [0001] The invention relates to the technical field of switchgear, in particular to a gas insulated switch. Background technique [0002] Cabinet-type gas-insulated metal-enclosed switchgear, referred to as C-GIS, is an expansion of high-voltage GIS products in the medium-voltage field. It uses low-pressure SF6 gas, N2 gas or mixed gas as the insulating medium of the switchgear, uses vacuum or SF6 as the arc-extinguishing medium, and concentrates and seals medium-voltage components such as busbars, circuit breakers, and isolating switches in the box. Using modern insulation technology, breaking technology, manufacturing technology, sensing technology and digital technology, it is a high-tech product integrating intelligent control, protection, monitoring, measurement and communication. It has small size, light weight, good safety and reliability. High performance, can adapt to the use of harsh environmental conditions and so on. [0003] The existing gas in...
