【 摘 要 】

In this paper, the heat generation of 110kV cable GIS terminal discovered by infrared thermal imager is briefly described. The causes of heat generation are discussed by means of sheath current detection and circulation calculation, and further analysed by high frequency partial discharge monitoring system, timely handling of equipment hidden dangers, to avoid the occurrence of vicious accidents. Through the analysis and judgment of this accident, the significance of infrared temperature measurement, sheath current detection technology and high frequency partial discharge detection technology for the discovery of cable defects is proved, which provides a basis and reference for future work.
