架空地线取能及微波探测在输电线路外破监测的研究应用

Research and application of overhead ground wire acquisition and microwave detection in fault diagnosis of transmission line

输电线路周边的施工行为日益增多,现有的外力破坏监测方式主要有视频、激光对射等,设备功耗大,实时工作对电源容量要求较高,而现有的外力破坏监测装置普遍采用太阳能方式供电,可靠性受天气条件影响,难以保障监测系统的可靠工作。针对以上问题,本文研究了一种采用架空地线感应取电方式供电、基于低功耗微波探测技术的外破监测方法,现场有异常情况时启动图像设备拍摄现场状况取证,从而提高防外力破坏监测系统工作的可靠性。

The construction behavior of the transmission lines around the transmission line is increasing day by day. The existing methods of monitoring the external force damage are video, laser and so on. The power consumption of the equipment is large, and the real-time work has higher requirements on the power supply capacity. The existing external damage monitoring device is the use of solar power, reliability affected by weather conditions, it is difficult to protect the reliable operation of the monitoring system. In view of the above problems, this paper studies a kind of external fault monitoring method based on low power microwave detection technology, which uses the overhead ground wire to take power supply, and starts the image equipment shooting scene situation forensics, greatly improves the anti-external force Destroy the reliability of the monitoring system.
