摘　　要：笔者利用电场数值分析等方法,对额定电流为3150 A、用于220 kV系统中的SF_6气体绝缘金属封闭开关设备(GIS)进行了优化设计,针对GIS中的断路器、隔离及接地开关、盆式绝缘子、出线套管、油气套管、母线等各种元件,通过对其结构、布置方式、优化后的电场强度等各种因素的详细描述,展示了新产品的研发过程。设计优化后的252 kV GIS结构更加紧凑,尺寸更小,而且其额定电流由原来的3150 A提高到4000 A,并顺利通过了产品的型式试验。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.
