摘要
10 kV架空配电线路是配电网重要组成部分,做好10 kV架空配电线路设备的运维检修工作尤为重要。长期以来10 k V配电架空线路的带电检测多依赖红外测温法,运检效率低,运维水平不高。在10 kV架空配电线路上,探索超声波局部放电检测技术的应用,典型案例证明超声波局部放电技术能有效发现多种缺陷或隐患,检测速度快,测量精度高,显著提升了10 kV配电网架空线路设备的巡检效率和运检水平。
The 10 kV overhead distribution line is an important part of distribution network.It is particularly important to ensure the maintenance and operation of 10 kV overhead distribution line equipment.For a long time,the live detection of 10 kV overhead distribution lines relies heavily on infrared temperature measurement method,which is under efficient and out of date.The application of ultrasonic partial discharge detection technology on 10 kV overhead distribution lines is explored.Typical cases prove that the ultrasonic partial discharge technology can effectively detect many defects or hidden dangers.The detection speed is fast and the measurement accuracy is high,which significantly improves the inspection efficiency and the detection level on overhead distribution lines of 10 kV distribution network.
