摘要
六氟化硫电气设备中水分含量超标威胁设备和电网的安全运行,必须对其进行准确测量和严格控制。本文在9篇文献的基础上综述了目前采用的四种测量六氟化硫电气设备中水分含量的方法的原理,比较了它们的优缺点,结合模拟实验结果和现场经验,指出阻容法是六氟化硫气体水分含量测量方法的发展趋势,并对阻容法提出了一些改进的建议。
As the moisture content over standard in sulphur hexafluoride(SF 6 )gas-insulated apparatus will menace the operation of apparatus and grid,it should be measured accurately and controlled strictly.The principles of four moisture content measurement methods for SF 6 gas-insulated apparatus are introduced and the advantages and disadvantages of them are compared in the paper.It is shown that the resistance-capacity method is the developing trend of moisture measurement based on the experimental results and field experience.Some suggestions amelioˉrating the resistance-capacity method are presented.
