摘要
近几年,我国冬季时常有冰雪天气,使处在恶劣环境下的架空输电线路大面积覆冰,导致杆塔、绝缘子倒塌,严重影响输电网的正常运行。在分析输电线路覆冰与气候的关系以及各种输电线路覆冰检测方法的基础上,利用光纤光栅传感技术,设计了一种架空导线覆冰情况自动检测系统,可代替人工对输电线覆冰情况巡检,并实时记录覆冰情况,进行预报警,提高了线路运行的可靠性。
In recent years, because of the freezing rain and snow weather, overhead transmission line has ice coating in large area in winter, which affecting the normal operation of power network. Based on the analysis of transmission line icing and climate relationship, a kind of automatic monitor system of ice coating on overhead transmission line is designed by use of the fiber bragg grating sensing technology. The system instead of artificial inspection can record the ice coating condition and forecast alarm, improve the operation reliability of lines.
