Abstract

The invention discloses an electrified on-line detection system for power transmission line fittings, the system comprises a climbing device and a detection device, the climbing device comprises a mounting seat, and the detection device is fixed on the mounting seat. The climbing device is used for conveying the detection device to a power transmission iron tower, then the detection device is usedfor detecting parts such as a power transmission line clamp, defects on the power transmission line are found as soon as possible, and the normal power supply is maintained. Moreover, the device is electrified and autonomously online, the detection operation can be carried out without power failure, the high-altitude operation risk of personnel is avoided, the problems of economic loss and powersupply reliability caused by the power failure are also reduced, and the technology has a wide popularization and application prospect in a power system.

Description

technical field [0001] The invention relates to a power detection device, in particular to a detection system for a metal fitting of a power transmission line. Background technique [0002] During the long-term operation of high-voltage transmission lines, due to external factors such as lightning strikes, icing, and wind deviation, as well as problems in their own materials, manufacturing, and installation processes, defects such as oxidation corrosion of fittings and loose joints are prone to occur, thus threatening the safety of the transmission system. run. For a long time, there has been a lack of effective detection methods for defects in internal materials and mechanical structures of components such as transmission line clamps, and it is difficult to accurately assess their hazards to line operation. [0003] X-ray non-destructive testing technology is a new type of detection technology that can be imaged in real time. It can realize the internal material of transmi...
