特高压换流站油中溶解气体在线监测装置运行分析

Operation Analysis of On-line Monitoring Device for Gas Dissolved in UHV Converter Station Oil

国网特高压换流站在运变压器油中溶解气体采用国内市场主流技术,为气象色谱型多组分定性分析技术,占在运特高压换流站93%,光声光谱技术占7%。从故障率和运维成本来看,河南中分、宁波理工等国产设备占据很大优势。此文同时对光声光谱技术进行了分析,提出了其在特高压直流工程的应用前景。

State Grid UHV Converter uses the domestic market mainstream technology to dissolve gas in operating transformer oil,which is meteorological chromatography multi-component qualitative analytical techniques, accounting for 93% of operating UHV converter station.The photo-acoustic spectroscopy technology also accounts for a certain percentage of 7% .From the perspective of failure rate as well as operation and maintenance costs, Henan Zhongfen, Ningbo Institute of Technology and other domestic equipment occupy great advantage.This paper also analyzes photo-acoustic spectroscopy technology and presents its application prospects in UHVDC Droiect.
