高压套管油流外溢的化学检测方法研究

Study on Chemical Detection Methods of Oil Flow Spillover in High Voltage Bushing

摘要: 高压套管油流外溢问题将极大地影响套管工作的可靠性，但目前还缺乏行之有效的检测手段。本文基于高压套管油的化学组分及特性，探讨了用化学检测手段发现高压套管油流外溢问题的可行性，并重点对加成反应、酸碱滴定反应、氧化反应进行了实验研究，研究结果表明，使用化学检测手段检测油流外溢具有一定的可行性，后续可利用加成反应或氧化反应明显的颜色变化开展深度辨识。本文的研究成果将对现场设备巡检及相关检测装置的研发提供重要参考。

Abstract: The oil flow spillover problem can influence the running reliability of high voltage bushing. However, there are few useful detection methods. Based on the chemical contents and characters of bushing oil, this paper discusses the possibility of the chemical detection methods on that problem. It pays heavy attention on addition, oxidation, and acid and alkali reaction. The results show that it is possible to use chemical detection methods on oil flow spillover phenomenon, which can make use of the color change to do depth identification. This research result will provide an important reference to routing inspecting and detection device development.
