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.
