高压开关设备SF_6气体微水含量在线监测可行性试验研究

Feasibility Study of High Voltage Switch Equipment SF_6 Gas Moisture Content On-line Monitoring

本文对SF6气体微水含量带电检测和在线监测技术进行了对比试验研究,发现采用微水含量在线监测装置与露点式离线检测装置的测试值相差甚远,对SF6气体微水含量的在线监测误差较大,不利于现场判断。因此,目前SF6气体微水含量在线监测应用于生产实践暂不具备可行性。

This paper carried out comparison experimental study of SF6 gas micro water content charged detection and online monitoring technology.The study found that the micro water content test value using online monitoring devices and dew point type detection device is far away.To SF6 gas mi-cro water content on-line monitoring,the error is large,which is not conducive to the scene deter-mine.Therefore,the SF6 gas moisture content on-line monitoring used in the practice does not have the feasibility.
