A new type of environmentally friendly gas-insulated metal-enclosed switchgear

Abstract

The invention provides a novel environmentally-friendly gas-insulated metal-enclosed switch device, including a cabinet, a longitudinal partition plate, a transverse partition plate, a fixing plate, apower supply gate valve, a vacuum partition eliminating exhaust plate structure, a protective fix connection box structure, a static electricity eliminating wire structure, a breaker, a wiring cone,a box door, a door handle, a power-off operation table, a circuit breaker, an instrument room and a mounting door, wherein the longitudinal partition plate is bolted to the middle position on the leftside of the inner wall of the cabinet. The L-shape partition plate, the connecting rod, the fix column, the arc cone and the cabinet are arranged, the arc can be eliminated in a vacuum state, and thearc can be prevented from injuring the work personnel; The installation of cable box and rubber ring is conducive to protecting cable and preventing cable box from damaging cable and affecting cablework; The fixing ring, fixing bolt, static connecting wire, connecting ring and connecting bolt are arranged to eliminate static electricity carried by the equipment and prevent the static electricityfrom hurting the staff.

Description

technical field [0001] The invention belongs to the technical field of metal-enclosed switchgear, and in particular relates to a novel environment-friendly gas-insulated metal-enclosed switchgear. Background technique [0002] According to national standard requirements and user requirements: the IAC level (internal fault current magnitude and short-circuit duration) should be taken as the key indicator of switchgear design, and the allowable duration of internal fault arc should not be less than 0.5 seconds. The circuit breaker room, busbar room and cable room should be equipped with independent pressure relief channels and pressure release devices, and the nozzle of the pressure release device should be directed away from inspection channels and other equipment. Since the switchgear is only accessible to authorized personnel, there are operation or maintenance channels on the front, back and side of the switchgear, and authorized personnel may touch the front, back and sid...
