Abstract
In this paper,based on the electric field numerical analysis method,the optimized design of Gas Insulated metal-enclosed Switchgear (GIS) for 220 kV system and rated current 3 150 A has been carried out; through detailed description of the structure,arrangement,the optimized electric field strength factors,for various kind of component in GIS such as the circuit breaker,disconnector,earthing switch,disc insulator,outlet bushing,oil gas bushing and bus bar etc.,the new product development process is showed. The structure of 252 kV GIS are more compact and smaller,after the design optimized. Moreover,while rated current increased from the original 3 150 A to 4 000 A,the product is still successfully passed the type testing.关键词
