摘要
文中以变压器油色谱、直流偏磁、绝缘子污秽度三类成熟度和数据有效性较高的在线监测装置为主,对其监测应用原理进行阐述,并结合实例对江苏电网输变电在线监测装置的现状和应用情况展开分析。分析认为需提高在线监测装置的可靠性并加强在线监测数据与故障缺陷的关联性,推进在线监测装置智能化发展。
This paper pays attention to three mature types of online monitoring devices, namely transformer oil chromatography, dc magnetic bias and insulator pollution degree, which have high data availability. The principles of monitoring devices are illustrated in the paper. By practical application cases, the status of online monitoring devices utilized in Jiangsu power grid transmission and distribution system are analyzed. The result of analysis shows it is necessary to improve the reliability of online monitoring device and to strengthen the relationship between online monitoring data and fault defects detection which will promotes the intelligent development of online monitoring devices.
