Description

Technical Field

[0001] The utility model relates to the technical field of transmission line detection, in particular to a transmission line fault detection device. Background Art

[0002] The transmission line is a crucial part of the power system, mainly used for efficiently transmitting electric energy. Once a fault occurs in the transmission line, it may lead to the interruption or instability of power transmission, seriously affecting the normal operation of the power supply system. It is crucial to promptly identify and repair the faults of the transmission line to ensure that the electric power can be stably and reliably transmitted to the user end.

[0003] Application No. 202322293853.6 discloses a transmission line fault detection device, including: driving mechanisms arranged on both sides of the detection box, several power connection plates are arranged on the upper part of the detection box, contact coils are arranged at the ends of several power connection plates, the contact coils are in contact with the transmission line, and the driving mechanism includes: telescopic plate groups symmetrically arranged on both sides of the detection box, an assembly frame is arranged at the end of the telescopic plate group, a fixing plate is arranged on the assembly frame, a rotating shaft is arranged on one side of the fixing plate, and a rolling wheel is arranged at the end of the rotating shaft. The staff only needs to respectively lap the two rolling wheels on two parallel transmission lines, and at the same time adjust the angular position of the power connection plate to make the contact coil lap on the transmission line. The driving device drives the driving shaft cylinder to rotate, and then drives the whole detection device to move forward. The contact coil quickly detects the epidermal crack of the transmission line. Compared with the traditional detection method, the risk coefficient is lower and the detection efficiency is higher.

[0004] The above solution has deficiencies in use. When moving on the transmission line only by the power of a single rolling wheel, there may be a sliding situation, which will cause the contact coil unable to move, thus affecting the detection efficiency of the transmission line. Therefore, we propose a transmission line fault detection device to solve the above problems. Summary of the Utility Model
