摘要

本文对一例SF

电流互感器典型漏气缺陷进行跟踪和定位

通过充气阀门金属检测和腐蚀成分检测

查明了漏气缺陷产生的原因

最后提出了相关处理建议

对户外充气类设备漏气缺陷诊断和充气阀门材质选型提供了参考。

Abstract

This paper tracks and locates a typical gas leakage defect of SF

current transformer. Through metal detection and corrosion composition detection of inflation valve

the causes of the gas leakage defect are found out. Finally

relevant treatment suggestions are put forward

which provide a reference for the diagnosis of gas leakage defect of outdoor inflation equipment and the material selection of inflation valve.
