摘要

分别研究了周围空气温度对SF6气体水分含量变化和检测仪器读数的影响。实验室测量结果和现场实测结果都证明SF6气体水分含量随周围空气温度升高而升高。在相同条件下

研究了周围空气温度对两种SF6气体水分含量检测仪器的影响。结果表明

周围空气温度对阻容式水分含量检测仪器影响较大

而对露点传感器影响较小。

Abstract

The influences of environmental temperature on the moisture content in SF6 gas and moisture measurement instruments are studied in this paper. Both the laboratory experimental results and the on-site experimental results show that the moisture content will rise if the environmental temperature rises. Under the same condition

the influence of environmental temperature on the reading of two types of moisture measurement instruments is investigated too. It is shown that environmental temperature has much greater influence on the resistance-capacitance moisture measurement instrument than the other one.
