新型输电线路防外力破坏预警装置的研究与应用

Research and Application of Mobile Detection and Monitoring Device for Transmission Lines

通过研制基于TA感应取电技术的输电线路防外力破坏预警装置,实现了直接对线路周边状态进行检测,研究和开发一种直接安装于输电导线覆盖需要保护区域的装置,符合输电线路安全防护的需要。其工作不受杆塔倾斜、振动、摇摆和杆塔附近树木等影响,装置通过感应方式获取工作电源,相比于安装在杆塔的具有大面积太阳能电池板的系统,使其也不受连续阴天的影响。该输电线路防外力破坏预警装置体积小巧,现场安装简单,可长期可靠运行。

This article develops a transmission line anti external force damage warning device based on TA induction power extraction technology,which realizes direct detection of the surrounding state of the line.It studies and develops a device that is directly installed on the transmission line and directly covers the area that needs protection,which meets the needs of transmission line safety protection.Its operation is not affected by tower tilting,vibration,swaying,and trees near the tower.The device obtains the working power through induction,making it not affected by continuous cloudy days.Compared to systems installed on towers with large areas of solar panels,this transmission line's anti external force damage warning device has a compact size,simple on-site installation,and can operate reliably for a long time.
