摘要
由于SF6(六氟化硫)气体在超低温条件下产生部分液化,使得SF6断路器内的SF6气体密度下降,降低了SF6断路器的开关能力和绝缘水平,无法保证高压SF6断路器的可靠运行;为此,提出了采用混合气体,或者采用加热SF6气体的方法,解决高压SF6断路器在严寒地区可靠运行的问题。
Because SF6 gas produces part of liquidation under super low temperature, SF6 gas density decrease inside SF6 breaker, reduce switch and insulate level of SF6 breaker, which can't guarantee SF6 breaker reliable operation. So puts forward adopting mixed gas or taking heating SF6 gas to solve SF6 breaker reliable operation in rigid area.
