摘要
电力电缆是传输电能的重要设备,其运行状态影响到电力系统的安全和稳定.红外测温技术是一种非接触、无损、高效和可视化的测温手段,可以准确地检测出电缆及其附件的表面温度分布和异常热点,及时发现和排除故障隐患.阐述了红外测温技术的基本原理和特点,分析了电力电缆发热的原因和类型,介绍了不同种类红外测温的特性,最后针对站内电力电缆的异常发热原因进行了分析并提供了对应的改进措施.
Abstract
Power cable is an important equipment for transmitting electric energy,and its operation sta-tus affects the safety and stability of the power system.Infrared temperature measurement tech-nology is a non-contact,non-destructive,efficient and visual temperature measurement method,which can accurately detect the surface temperature distribution and abnormal hot spots of cables and their accessories,and find and eliminate hidden faults in time.This paper expounds the basic principles and characteristics of infrared temperature measurement technology,analyzes the causes and types of power cable heating,introduces the characteristics of different types of infrared tem-perature measurement,and finally analyzes the causes of abnormal heating of power cables in the station and provides corresponding improvement measures.
