摘要
该文对分相式GIS设备常见的发热类型进行系统阐述,归纳GIS设备电流致热型发热与电压致热型发热的类型、原因分析及处理措施。分别对GIS设备内部导电杆等导流设备和GIS外壳组部件进行分类发热原因分析,首次提出外壳电流基于KCL和KVL网络化分析对于GIS外壳组部件发热的分析方法,对GIS外壳构架异常接地引起的大范围发热缺陷提供处理思路。为电力系统带电红外检测提供重点测量部位和问题诊断分析的系统方法。
This paper systematically expounds the common heating types of split-phase GIS equipment,and summarizes the types,cause analysis and treatment measures of current-induced heating and voltage-induced heating of GIS equipment.The causes of heating of conductive equipment such as conductive rods and GIS shell components in GIS equipment are classified and analyzed,and the analysis method of shell current based on KCL and KVL network analysis for GIS shell components is put forward for the first time,which provides an idea to deal with the large-scale heating defects caused by abnormal grounding of GIS shell frame.It provides a systematic method of key measurement position and problem diagnosis and analysis for live infrared detection of power system.
