Gas insulated switchgear (GIS) equipment all-weather flexible overhaul chamber system

Abstract

The invention belongs to the field of power system gas insulated switchgear (GIS) equipment overhauling, and discloses a GIS equipment all-weather flexible overhaul chamber system. The GIS equipment all-weather flexible overhaul chamber system comprises an overhauling chamber skeleton system, a rain-proof fabric system, a connection fastening auxiliary accessory system and an intelligent monitoring system; the overhauling chamber skeleton system comprises an expandable gas column frame type double-layer wall unit, a general roof, a specially-made roof and a single-layer door structure unit; the rain-proof fabric system is mounted at the exterior of the overhauling chamber skeleton system and comprises a transparent PVC film and oxford cloth; the connection fastening auxiliary accessory system is arranged in the overhauling chamber skeleton system and comprises a gummizug and a wind sand preventing box; and the intelligent monitoring system is arranged in the overhauling chamber skeleton system. According to the GIS equipment all-weather flexible overhaul chamber system, it can be ensured that GIS equipment can be unfolded and disassembled for being overhauled in the severe weatherenvironment of rain and snow, so that the GIS equipment all-weather flexible overhaul chamber system exerts the higher efficiency during overhauling, the blackout time of a large area is greatly shortened, and the economic efficiency is improved.

Description

technical field [0001] The invention belongs to the field of maintenance of GIS equipment in a power system, and in particular relates to an all-weather flexible maintenance room system for GIS equipment. Background technique [0002] GIS (Gas Insulated Switchgear, SF6 Gas Insulated Totally Enclosed Combiner) equipment is a high-voltage electrical assembly equipment for gas-insulated fully enclosed combined switchgear. It uses gas SF6 as the insulating medium to connect fast grounding switches, isolating switches, circuit breakers, and voltage and voltage mutual inductance. The circuit breaker, busbar, lightning arrester, cable terminal and inlet and outlet bushings form a complete system in a certain way, and control the opening and closing of the GIS equipment circuit breaker through hydraulic / pneumatic, spring mechanism operation, etc. With the increasing scale of the power grid, in recent years, GIS equipment has gradually replaced other switchgear to become the mainstre...

AI Technical Summary

Problems solved by technology

From the existing experience, the most commonly used method is the direct maintenance method in the natural environment, but there are many deficiencies in this method: for example, the weather conditions determine the construction progress, and the installation environment affects the quality of maintenance, etc.

However, after the GIS equipment fails, it can only be carried out by dismantling and overhauling. After the overhaul, it is necessary to vacuumize the GIS equipment and prevent impurities in the air from entering. Therefore, the operation can only be carried out when the weather is fine, and the weather conditions are One factor that cannot be accurately grasped is that there is more rain in the south and it is difficult to ensure humidity; the weather in the north is relatively cold and it is difficult to ensure the temperature

And even in the sunny open-air construction, due to the frequent occurrence of smog, impurities or dust in the air are easy to settle and adsorb on the inner wall of the GIS equipment, causing continuous discharge and causing great safety accidents

[0004] In summary, the existing problems in the prior art are: after the GIS equipment fails, it can only be carried out by dismantling and overhauling. Only work when the weather is clear

But its operation is inconvenient
