Abstract

The invention discloses environment-friendly gas fully-sealed fully-insulated switch equipment, which comprises an accommodating assembly, an inflating assembly and an arc extinguishing assembly, andis characterized in that the inflating assembly is arranged at the side part of the accommodating assembly, and the arc extinguishing assembly is arranged at the side part of the accommodating assembly. According to the invention, the accommodating assembly forms a sealed space, the sealing of an electrical structure installed in the sealed space is facilitated, insulation is conducted, the interior of the cabinet body is enabled to maintain a micro-positive pressure environment, and the impact on operation of the equipment from water vapor and dust is avoided; nitrogen, carbon dioxide and dryair can be introduced into the accommodating assembly through the inflating assembly to form gas needed by insulation, SF6 gas is prevented from being used, and harm to the environment is reduced; and arc extinguishing is conducted through an arc extinguishing assembly, closing is achieved by replacing a grounding switch, multiple times of maintenance-free grounding short circuit closing can be easily completed, metal steam generated in the opening and closing process is prevented from being discharged, and insulating gas is prevented from being polluted.

Description

Technical field [0001] The present invention relates to the technical field of switching equipment, and more particularly to environmentally friendly gas full sealing full insulating switching equipment. Background technique [0002] A large number of medium-pressure switchgers is used in electrified railway traction and signal power supply systems. It is an indispensable product of railway operation and is related to railway safety and reliable operation. Medium pressure switch equipment has experienced more than 80 years of development. After opening, box, metal closed-type stage, with technology and process progress, equipment function and performance becomes more and more perfect, the current technology innovation is safer, reliable, miniaturized, Environmentally friendly, intelligence, etc. are continuously launched. [0003] In order to reduce equipment maintenance, provide operational reliability, medium-pressure full-sealed ring cabinet and gas insulating metal closed swi...
