Vacuum circuit breakers can also be equipped with tension springs, which is a new generation of switchgear. The whole cabinet adopts air insulation combined with sulfur hexafluoride gas chamber, which is compact and expandable, suitable for distribution automation. The charging cabinet has the characteristics of compact structure, sensitive operation, reliable interlocking, etc. It can provide satisfactory technical solutions for different user needs in different places of use (especially in harsh environments. Through the selection of sensing technology and the latest maintenance relays, SF6 The gas charging cabinet and its combination of advanced technical performance and simple and sensitive equipment solutions can fully meet the different needs of users.
The inflatable box accessories are especially suitable for places with high demand for electricity such as airports, subways, and railways. Small secondary substations, switch stations, box-type substations, residential areas, industrial and mining enterprises, large power system shopping malls, etc.
In addition, the increasingly prosperous industry and transportation in the future development of the western region will also make the grid switchgear vulnerable to pollution and corrosion. The radial air-insulated switchgear used in the distribution network can no longer meet the requirements due to the limitation of environmental conditions, and has begun to be gradually updated. 12kV cabinet-type gas-insulated metal-closed switchgear (hereinafter referred to as C-GIS inflatable cabinet has a history of only a few years in my country, but due to its small footprint, high degree of intelligence, no protection, and full working conditions, etc. New has become a new choice. In recent years, Sichuan, Yunnan, and Guizhou have successively arranged several large-scale transformation of power grid switchgear, changing the traditional 15-20-year update cycle into continuous frequent update. Especially some newly started construction 12kCGS is selected from the planning source to meet the necessary conditions for normal use in a certain period of time. At present, C-GIS is used more and more in the fields of metallurgy, petrochemical, mining, development zones, rural rail transit, high-rise buildings and other fields .
