摘要

笔者将一台离线的SF

变压器外壳作为试验容器

对变压器内SF

气体进行局部加热试验

全程对气体分解产物进行跟踪检测

将模拟过热点温度下的检测结果进行分析研究

找出SF

气体过热点温度与气体分解产物的变化关系

得出了SF

气体在加热温度不断升高的过程中顺序产生HF、SOF

、SO

的结论

同时确定了上述各分解气体在加热过程中出现的温度区间

旨在给有效评估SF

设备状态、对设备内部故障性质进行判断提供参考。

Abstract

Taking an SF

transformer shell as chamber

we locally heated the SF

gas in transformer to measure the gaseous decomposition products during heating process.The results show that HF

SOF

and SO

appear orderly with rising temperature.By analyzing the measurements

the relationship between thermal decomposition of SF

gas and overheat temperature is discovered

and the temperature range corresponding to each gaseous decomposition product is revealed

which may facilitate running condition evaluation and internal fault determination of electrical devices.
