红外、紫外检测技术在特高压输电线路线路中的应用

特高压输电线路具有结构参数高、输送容量大、运行电压高、杆塔高、绝缘子串长、绝缘子片数多、途径地域广等特点,运行的可靠性比常规的高压、超高压输电线路要求高,因此使得现有的传统检测方法已不能完全满足特高压输电线路的要求。文章从我国现有高压、超高压输电线路的运行情况分析了红外、紫外检测技术,并就通过红外、紫外检测手段所发现的设备缺陷结合计算机软件进行了分析,给出了红外、紫外检测在特高压输电线路上应用时所检测的关键部位,并说明其依据,为在±800 kV特高压直流和1 000 kV特高压交流输电线路中开展红外、紫外检测技术的重要性和必要性提供参考。

Application of IR and UV Detection Technology in UHV Transmission Lines

UHV transmission line has the characteristics such as the high structural parameters,large transmission capacity, high operating voltage, high towers, long insulator string, multiple insulator film and wide geographical area, etc. ,the reliability of operation is higher than conventional HV and EHV transmission lines. Thus the existing traditional methods can not fully meet the requirements of UHV transmission lines. This article analyzes IR and UV detection technology from the operation of the existing HV and EHV transmission line as well as the equipment defects which is found by IR and UV detection methods with computer software,gives the key parts tested by IR and UV detection, and explains their basis. It provides reference for the importance and necessity to carry out IR and UV detection technology in ± 800 kV HVDC and 1 000 kV UHV AC Transmission Lines.
