Abstract

The invention discloses an equipotential charged X-ray detection method for overhead line hardware, which comprises the step of carrying out defect detection on the overhead line hardware by moving and rotating an X-ray detection device, and specifically comprises the following detection steps: completing conversion and installation of the X-ray detection device and a protection device from ground potential to equipotential; detecting personnel are converted from ground potential to equipotential; a detector performs transillumination of different angles at the same hardware fitting position through rotation of the X-ray detection device in the protection device, and the detector is converted from equipotential to ground potential; the conversion of the X-ray detection device and the protection device from equipotential to ground potential is completed; acquiring and analyzing images to obtain a detection report. According to the invention, an equipotential mode is adopted for detection, live detection of the overhead hardware fitting can be realized without too many auxiliary devices, the detection can be completed by at least two persons, the resource cost input is low, the detection is comprehensive and reliable, and the method is applied to various scenes.

Description

technical field [0001] The invention relates to the technical field of electric equipment defect detection, in particular to live detection of high-line transmission line defects, and in particular to an equipotential charged X-ray detection method for overhead line fittings. Background technique [0002] Overhead lines are currently the most important power equipment for long-distance transmission of electric energy, featuring high voltage levels and large currents. Connecting fittings are an important part of overhead lines, and their quality directly affects whether the transmission line can work normally and whether the power grid can operate safely and reliably. The tension clamp is a metal tool that fixes the wire, bears the tension of the wire, and hangs the wire to the tension string or the tower. Once an accident occurs, it will directly cause the wire to be disconnected and the line to be out of service, causing greater damage to the power grid company. Economic l...
