Novel environment-friendly gas insulation ring main unit

Abstract

The invention, which belongs to the technical field of electrical equipment, provides a novel environment-friendly gas-insulated ring main unit comprising a mechanism box, a gas box, a cable chamber,and a pressure relief chamber; the gas box is of a closed structure, dry air with a pressure of 0.015 Mpa is introduced into the gas box, and a pressure relief valve is arranged between the gas box and the pressure relief chamber; a circuit breaker actuating mechanism and an isolation grounding three-position switch actuating mechanism are arranged in the mechanism box. A circuit breaker switch and an isolation grounding three-position switch are arranged in the gas box; the gas insulation ring main unit has the advantages of being small in size, environmentally friendly, integrated in function, high in reliability, free of maintenance and the like, the defects of manufacturing experience of an existing solid insulation ring main unit are overcome, and pollution to the atmosphere and harmto a human body caused by emission or leakage of SF6 gas and decomposers of the SF6 gas due to the fact that the SF6 gas is used are avoided.

Description

Technical field [0001] The invention belongs to the technical field of electrical equipment, and particularly relates to a new type of environment-friendly gas insulated ring network cabinet. Background technique [0002] In the current switch industry, ring network cabinets have been widely used, and most of its mainstream solutions are SF 6 Gas insulated SF 6 There are two ways of gas arc extinguishing and solid insulation vacuum arc extinguishing. But SF 6 The gas can decompose toxic gas under the action of electric arc, and the harm to human body and the environment is huge, and SF 6 Gas can cause great pollution to the atmospheric environment. However, the production technology, production efficiency, insulation shielding technology and insulation surface spraying technology of the solid insulated ring network cabinet are not mature enough, and the partial discharge index is not easy to control. Therefore, a new technical solution is urgently needed to solve this problem am...
