摘要
用气相色谱法检测油中溶解的可燃气体可以预报变压器内部存在的潜伏性故障。用本文研制的在线监测仪检测油中的氢气比气相色谱法更能及时地做到这一点。本文介绍了该仪器的原理和结构特点。该仪器具有结构简单、安装方便、性能稳定、寿命长、不需要经常维护等特点。
Continually monitoring the concentration of hydrogen dissolved in transformer oil by gas chromatography can discover the internal trouble of transformer earlier.The apparatus investigated is used for transformer on line as indicator of potential fault.This paper describes the principle and structure of this monitoring device .This device has the following advantages: simple structure, long lifetime, stable performance, easy to install and less maintenance.
