[0077]

[0078] Compared with traditional monitoring technology, the advantages of the capture device are as follows: Traditional monitoring technology generally adopts interval shooting or loop recording, with poor event capture capability, high power consumption, low timeliness, and no fault alarm capability.

This device can realize the instantaneous capture of fault flashover, transmission corridor, channel environment, mechanical intrusion, external force damage and other data collection and analysis through all-weather online monitoring of transmission lines. Then upload and receive data through the wireless network, which is convenient for background management personnel to understand the on-site dynamics in real time and control and solve the hidden dangers of transmission line failures in a timely manner.

[0079] The advantage of the ice detection device is that it has good resistance to power frequency electromagnetic interference, can achieve accurate and complete data collection in an ultra-high voltage electromagnetic environment, and can accurately control the front-end equipment; the detection device often works in severe weather environments and should be designed to be self-powered, that is, it uses induction to obtain working power from the monitored line, which is maintenance-free and reliable.
