Problems solved by technology

[0002] Commonly used gas insulated switchgear, the insulating gas in the gas box is SF6 gas, SF6 gas is a gas with a greenhouse effect, its greenhouse effect has a large impact and a long attenuation period, and when the gas of the switchgear leaks, it will have a great impact on the environment
In order to avoid the above problems, environmentally friendly gas switchgears have been used. Most of the environmentally friendly gas switchgears on the market use the insulation method of the solid-sealed spine to cover the vacuum interrupter. The solid-sealed spine is made of epoxy resin formed by APG. Resin is a thermosetting material, which is difficult to recycle after use, which not only wastes materials but also pollutes the environment

Abstract

An environment-friendly gas switch cabinet is disclosed. The environment-friendly gas switch cabinet comprises a switch gas tank, wherein a circuit breaker / load switch and a three-station isolation earthing switch are arranged in the gas tank; and the switch gas tank is filled with nitrogen. The environment-friendly gas switch cabinet provided by the invention can prevent environment pollution caused by leakage of insulating gas, and is better in the insulating performance without increasing the volume; insulating side plates, each segmentation shaft, a three-phase static contact base, and a three-phase transmission shaft are all made from thermoplastic engineering plastics in an injection moulding manner; and the used materials can be recycled, so that waste of materials and environment pollution can be avoided.
