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.
