污秽在线监测光传感系统在多雨山区的应用

Application of Optical Sensing System for Contamination On-line Monitoring in Rainy Mountainous Area

南方多雨山区的雨水对输电线路绝缘子的清洗较为频繁,使得绝缘子的污秽人工取样存在一定的困难。利用光传感技术可进行绝缘子污秽的实时监测,通过适应性设计的光传感系统用于贵州电网的三个监测点超过一年的现场运行测试,初步表明在线监测设备运行稳定,数据合理,适用于多雨山区的电网外绝缘污秽监测。

The insulator of transmission line in the southern rainy mountainous area is frequently washed by rainwater, so it is difficult to measure the contamination degree of the insulator by manual sampling. The optical-sensing technique can be used to detect the contamination of the insulator in real time. Through the running test of three monitoring stations in Guizhou power grid over one year, it is preliminarily showed that the on-line monitoring system runs stably with the reliable data performance, and is suitable for the contamination on-line monitoring in the rainy mountainous area.
