摘　　要：为了提高特高压输电线路的稳定性,提出了一种红外监测绝缘子的方法。在分析绝缘子结构和电位特性的基础上,结合当前红外监测技术,采用泄漏电流量和温度作为研究参量,对绝缘子串不同结构、不同电位特性及同一泄露电流所产生的不同焦耳热有识别的进行红外热像;并与传统的检测方法进行对比。结果表明,红外监测具有操作方便、抗干扰能力强、自动报警、实现远程监测等优点。同时也提出了期待进一步研究的问题。In order to improve the stability of ultra-high voltage transmission lines, a method for the infrared monitoring of insulators was proposed in this paper. Take leakage amperage and temperature as parameters for study, based on analysis of the structure and characteristics of potential of insulators, and combining the existing infrared monitoring techniques, a different identification of infrared thermal image was carried out for the insulator strings＇ structures, characteristics of potential and Joule heat generated by the same leakage current. Compared with conventional detection methods, infrared monitoring has the advantages of easy operation, strong anti interference capability, automatic alarm and remote supervision function.
