摘　　要：针对我局《中国南方电网电力设备预防性试验规程》的要求,在年度GIS设备红外测温和热成像工作中发现一起252 kVGIS设备罐体发热的现象,结合实际对离相式母线罐体发热的原因和危害进行了详细分析,找出了设备发热的主要原因,并结合系统运行情况提出了相应的预防措施。结果表明,红外热成像在线监测技术在保证设备安全可靠运行中发挥了重要作用。According to the China Southern Grid Power Device Preventive Test Rules, a heating phenomenon of the 252 kV-GIS tank was detected in annual infrared temperature measuring and thermal imaging test. The causes and harm of the heating of the separated-phase bus tank are analyzed and the main cause of heating is found. Corresponding preventive measures are proposed considering the operation of the electric power system. It is pointed out that the infrared thermal imaging technology for online monitoring has played an important part in ensuring reliable operation of power device.
