[0002] At present, my country is planning and constructing ultra-high-voltage and ultra-high-voltage transmission lines on a large scale. The operation experience of ultra-high-voltage transmission lines in my country shows that lightning strikes are one of the main reasons for line tripping. A lightning rod is installed on the tower, and the current led by the lightning rod is detected to determine whether a lightning strike has occurred. However, the occurrence of lightning can only be detected when the lightning falls on the transmission line body. For lightning strikes that fall near the corridor of the transmission line, it cannot Effective detection, so that it is impossible to effectively analyze the lightning strike in the transmission line area

The invention provides a power line lightning strike detection device, which includes a casing, a photoelectric tube, a self-check mechanism, a display screen and a controller. Outside the body, it can detect lightning strikes around the transmission line, send electrical signals to the controller through photoelectric conversion, and the controller counts the number of lightning strikes, and the collected lightning information is used for lightning analysis and early warning of the surrounding environment of the transmission line etc. provide data support, and also set up a self-test function. The controller controls the electric telescopic rod to drive the loading plate and the photoelectric tube into the housing, and controls the flash to emit light to simulate lightning, so that the information of the photoelectric tube can be collected and controlled. The information processing of the device and the lightning strike display function of the display screen are used for self-inspection to ensure the validity of the lightning detection data in the surrounding environment of the transmission line.
Description
technical field [0001] The invention relates to the technical field of lightning protection for transmission lines, in particular to a lightning strike detection device for transmission lines. Background technique [0002] At present, my country is planning and constructing ultra-high-voltage and ultra-high-voltage transmission lines on a large scale. The operation experience of ultra-high-voltage transmission lines in my country shows that lightning strikes are one of the main reasons for line tripping. A lightning rod is installed on the tower, and the current led by the lightning rod is detected to determine whether a lightning strike has occurred. However, the occurrence of lightning can only be detected when the lightning falls on the transmission line body. For lightning strikes that fall near the corridor of the transmission line, it cannot Effective detection is carried out, so that the lightning strike situation in the transmission line area cannot be effectively anal...
