| 摘 要： | 由于SF6气体在超低温下产生部分液化，使得断路器内的SF6气体密度下降，降低了断路器的开断能力和绝缘水平；为此，提出了采用混合气体，或者采用加热SF6气体的方法，以解决高压SF6断路器在严寒地区能够可靠运行的问题。

| Abstract: | SF 6 gas would liquefy partly at super low temperature, so the density of SF 6 in a circuit breaker would decrease,and so did the interrupting ability and insulation level of the circuit breaker.Two methods that is,using SF 6 mixture or heating SF 6 gas,can be taken to solve the operational reliability of HV SF 6 circuit breaker serving at the inclement area. |
