Description

Indoor AC high-voltage gas insulated metal enclosed switchgear

Technical Field

The utility model relates to the technical field of closed switches, in particular to indoor alternating-current high-voltage gas-insulated metal-enclosed switchgear.

Background

The gas insulated metal enclosed switchgear is a metal enclosed switchgear and a control device, at least one part of which adopts gas higher than atmospheric pressure as an insulating medium, and GIS is an English abbreviation of a gas insulated totally enclosed combined electrical apparatus. The GIS is composed of a breaker, a disconnecting switch, an earthing switch, a mutual inductor, a lightning arrester, a bus, a connecting piece, an outgoing line terminal and the like, all the equipment or components are sealed in a metal grounded shell, and SF6 insulating gas with certain pressure is filled in the metal grounded shell, so the GIS is also called as an SF6 fully-closed combined electrical appliance, and the GIS is widely operated all over the world since the 20 th century and the 60 th era of practicality. GIS is widely used not only in the high-voltage and ultra-high voltage fields, but also in the ultra-high voltage field. Compared with a conventional open-type transformer substation, the GIS has the advantages of compact structure, small occupied area, high reliability, flexible configuration, convenience in installation, high safety, strong environment-adaptive GIS adaptability, small maintenance workload, maintenance interval of main parts of the GIS not less than 20 years, continuous progress and development of manufacturing technology for over 40 years, and great research and development on element structure, combination form, manufacturing process, use and maintenance aspects, wherein each GIS manufacturer focuses on two main targets of improving economy and reliability. With the successful development of the high-capacity single-voltage SF6 circuit breaker and the application of the zinc oxide arrester, the technical performance and parameters of the GIS exceed those of conventional switch equipment, the structure is greatly simplified, the reliability is greatly improved, and very favorable conditions are created for the further miniaturization of the GIS.

The existing body insulation metal closed switch equipment is integrated, can not be separated, is often inconvenient to install and disassemble, and can greatly waste time of workers if the equipment needs to be overhauled.
