摘　　要：介绍了新沈高800 kV罐式SF6断路器的研制开发过程和技术特点;基于气体质量守恒、能量守恒定律和牛顿第二定律,对其空载、T100s开断条件下压气室内气体压力特性进行了计算分析;应用有限体积法对其空载、T100s开断条件下二维气流场分布进行了计算分析;应用有限元计算方法,对其分合闸状态下的绝缘性能进行了计算分析;该罐式断路器的研制为中国750 kV输电线路的建设提供了经济可靠的技术和设备保障。This paper introduced the development process and technical characteristics of 800 kV tank SF6 circuit breaker in New Northeast Electric （shenyang）HV Switehgear Co.Ltd. Based on mass conservation law, energy conservation and Newton 2nd law, cylinder gas pressure characteristics, under the no load and T100s breaking conditions, were calculated and analyzed; Using finite volume method, the two-dimensional gas flow fields were calculated and analyzed; Using finite element method, its insulation performances, under the opening and closing position, were calculated and analyzed. The development of this tank circuit breaker provided the economic and reliable technology and equipment support to the construction of China＇s 750 kV transmission line.
