摘要

气相色谱分析在检测变压器各类故障方面发挥了很重要的作用

但离线检测存在很多缺点

针对离线检测方法操作的繁琐性

介绍了一种基于气敏传感器的在线监测系统

论述了用监测两种气体来实现对变压器油中溶解气体在线监测的原因和方法

对气体传感器和气体在线监测的硬件设计和通信软件设计等进行了具体的分析和探讨。

Abstract

Dissolved Gas Analysis（DGA） system to analyse the gas contents dissolved in transformer oil has ever played an important role in detecting various defects of transformer. However

many demerits exist in the off-line monitoring methods. Aiming at the demerits of the off-line monitoring methods with too complicated operation

an on-line monitoring system based on the gas sensor is presented in this paper. The reason and method which is used to detect the gas dissolved in transformer oil on line are described. The design of gas transducer and the hardwareas well as the software of communication is also introduced.
