Description

technical field [0001] The invention relates to the technical field of radio frequency electromagnetic wave detection, in particular to a detection device and method for corona discharge of transmission lines based on unmanned aerial vehicles. Background technique [0002] Due to the increasing shortage of power grid construction land and the increasing difficulty of compensation for young crops, the transmission projects are mainly multi-circuit lines on the same tower, and the proportion of compact transmission lines is increasing. With the standardization of equipment maintenance, transmission lines require close-range detection on towers or close-range detection of aircraft with pods. When working on the tower, at least 4 operators are required to cooperate with hoisting the instrument, which not only consumes manpower, but also easily damages the instrument during the hoisting process; the multi-circuit transmission lines on the same tower may also involve cooperating w...

Problems solved by technology

[0010] Aiming at the low sensitivity of the corona discharge detection method of transmission lines and the complex technical problems of the measurement circuit for radio frequency electromagnetic wave detection, the present invention proposes a detection device and method for corona discharge of transmission lines based on drones. Two different electromagnetic wave bands of radio frequency are used for detection and processing to realize the detection of abnormal discharge and corona discharge, so that the corresponding treatment can be done in time, which helps to improve the safety and reliability of the transmission line, and realizes less or even no need for personnel to work on the tower. Climb the tower, reduce the equipment risk and personnel operation risk in the operation process, and improve the initiative of equipment operation and maintenance
