SF_6气体湿度的表述方法与指标控制综述

Summary of expression methods and index control of SF_6 gas humidity

针对目前国内通用的电气设备中SF6气体湿度控制指标用体积分数来表示所带来的弊端和不足,通过对体积分数、露点和相对湿度等表示方法及特点的分析讨论,归纳得出采用压力露点或相对湿度作为电气设备SF6气体湿度的控制指标更为合理的结论。

SF6 gas humidity control index expressed by volume fraction brings drawbacks and insufficience in domestic general electric equipment,by analyzing the expression methods such as volume fraction,dew point and relative humidity,draws the conclusion that using pressure dew point or relative humidity as the control index of electric equipment SF6 gas humidity.
