摘要
通过现场的实例,说明镜面式露点仪及阻容式露点仪由于试验方法的不同,会在SF6气体存在某些杂质的情况下,使测得的露点值相差很大,从而导致由露点换算出来的SF6气体微水含量结果也相差很大。由此引发了对试验方法、监督指标、设备的安全运行等问题的讨论,并提出了一些建议。
The field data shows that the result of micro-moisture determination is quite different in the case of some im purities existing in the SF6 gas due to different testing method by using mirror reflect and R-C dew point meter.
Some suggestions are prensented and discussed by the author in this paper including the testing method,monitoring slander and the safe operation of equipments etc.
