摘要
介绍了红外测温技术在超高压电网中应用的原理、方法和系统构成。通过对较为常见的电容器和隔离刀闸的发热故障进行监测和分析发现,红外测温技术在超高压电网应用中具有无接触、不停电、不取样、不解体等优点,同时可以实现远距离、大面积的快速扫描和成像。给出了一些红外测温技术的总结性应用经验,以便更好地发挥红外测温技术在超高压电网中的作用,从而提高超高压电网设备的健康水平。
The application of an infrared temperature measurement technique in extra-high voltage （EHV） power systems is presented.Through monitoring and analysis of the common heat failures at capacitors and isolating switches,it is found that the infrared temperature measurement technique can scan and image a large area at a long distance quickly.It has the advantages of noncontact,no power cutting,no sampling and no disintegration.To let the infrared temperature measurement technique play a better role in EHV power systems,some experiences in the use of infrared temperature measurement technique are given.
