户外SF6断路器在严寒地区可靠运行的措施
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.
