Abstract

This paper introduced the development process and technical characteristics of 800 kV tank SF6 circuit breaker in New Northeast Electric（shenyang）HV Switchgear 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.
