Description
Technical field [0001] The present invention belongs to an overhead line lightning strike monitoring technique, and in particular, the present invention relates to an overhead line lightning strike monitoring device and a monitoring method. Background technique [0002] With the construction of smart grids, the power transmission network and communication network integrates the main development trend, and the safety and stability of the line is of great significance to the reliability of grid. At present, the transmission line often suffers from lightning strikes and is difficult to accurately position, and there is difficulty in troubleshooting, which seriously affects the operation of the power communication system. Especially for overhead lines of 110kV and below, the line operation and maintenance level is low, and the lightning is often ignored because of the large amount of fault inspections. [0003] In order to locate the lightning strike points of the overhead line, it h...
