摘要
介绍了330kV罐式断路器中六氟化硫(SF6)气体湿度测量的意义、原理和系统。对11台330kV罐式断路器进行了湿度测量 ,发现环境温度对SF6 气体湿度有显著影响。环境温度升高时 ,SF6气体湿度升高。通过理论分析 ,认为吸附作用是导致SF6 气体湿度随环境温度变化而变化的原因。
The benefit,principle and facilities of moisture measurement of SF 6 gas in330kV tank circuit-breakers are introduced in the paper.According to the experimental results,a conclusion that environmental temperature does influence the moisture of SF 6 gas can be drawn.When the temperature rises,the moisture rises correspondingly.The absorption existing on the surface between SF 6 gas and solid materials of circuit-breakers is the reason that causes the phenomenon above-mentioned.
