Cable rear connection type gas-insulated switchgear

Abstract

The invention discloses a cable rear connection type gas-insulated switchgear, and relates to the technical field of gas-insulated switchs.The cable rear connection type gas-insulated switchgear comprises a gas-insulated switchgear body, the outer wall of the gas-insulated switchgear body is fixedly connected with a condensation heat absorption pipe, the outer wall of the condensation heat absorption pipe is movably connected with a protective air bag, and one side of the protective air bag is provided with a bearing plate; an adjusting chamber is fixedly connected to the upper surface of the inflatable cabinet body, and a first arc-shaped elastic piece is arranged on the inner wall of the protective air bag. When the outer surface of the inflatable cabinet body is impacted, a bearing plate transmits impact force to multiple sets of transverse reset springs and lantern ring springs, meanwhile, the bearing plate is subjected to pressure deformation to generate counter-acting force, vibration impact transmitted on the bearing plate is counteracted, and therefore the surface of the inflatable cabinet body is protected; heat flows through the surface of the gas-insulated switchgear main body, the heat exchange area is increased by utilizing a rotary flow path of the condensation heat absorption pipe, the heat dissipation efficiency is improved, and heat accumulation in the gas-insulated switchgear main body is avoided.

Description

technical field [0001] The invention relates to the technical field of inflatable cabinets, in particular to a cable-connected inflatable cabinet. Background technique [0002] The inflatable cabinet is a new generation of switchgear. The main switch can use either a permanent magnet mechanism vacuum circuit breaker or a spring mechanism vacuum circuit breaker. The whole cabinet is combined with air insulation and sulfur hexafluoride gas compartment, which is both compact and expandable. , suitable for distribution automation. The inflatable cabinet has the characteristics of compact structure, flexible operation and reliable interlocking. It can provide satisfactory technical solutions for various applications (especially in harsh environments) and different user requirements. The adoption of sensing technology and the latest protection relays, coupled with advanced technical performance and lightweight and flexible assembly solutions, can fully meet the different needs of...

Problems solved by technology

[0005] 1. During the use of the existing cable rear-connected inflatable cabinet, when the electric inflatable cabinet is hit, the surface of the electric inflatable cabinet is easy to collide with other hard objects, resulting in damage to the surface of the electric inflatable cabinet. It is easy to damage the electronic components inside the electric inflatable cabinet;

[0006] 2. During the use of the existing cable rear-connected inflatable cabinet, because its surface is in a sealed state, the operating heat of the internal electrical components cannot be dissipated quickly, and the accumulation of heat will affect the service life of the internal components
