Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

At present, the connection of the wires and the ground wires of the overhead transmission lines in China mostly adopts crimping type hardware fittings, the hardware fittings generally comprise a strain clamp and a wire splicing sleeve, in the construction process, the strain clamp and the wire splicing sleeve not only bear all the tension of the wires or the ground wires, but also are electric conductors and are not detached after being installed, and when the wires or the ground wires do not penetrate through the crimping sleeve in place or steel core crimping does not meet the requirements, the wire or the ground wires can bury great hidden dangers for the safe operation of the lines.

In recent years, many wire breakage or wire drop accidents have occurred due to unqualified crimping quality of strain clamps or splicing sleeves. Therefore, accurate flaw detection needs to be performed on the inside of the strain clamp and the wire splicing sleeve, so as to ensure safe and uninterrupted power supply and safe power utilization.

When electrical insulators or circuit breakers on high voltage transmission line systems are in operation, for example at voltages of 110kV, 220kV, 500kV, 750kV and 1000kV or more, these devices are not only subjected to strong electrical stresses, but also to damage from environmental conditions.

Voids and inclusions may be introduced during the manufacture of the strain clamp or wire splicing sleeve, or cracks may be generated and propagated within the electrical insulator. Thus, when a strain clamp or wire splice is operated under high stress, partial discharge may begin due to partial discharge breakdown.

Furthermore, partial discharges may also occur along the boundaries between different insulating materials. Once initiated, the partial discharge can cause the insulation material to gradually degrade, eventually resulting in an electrical breakdown, and eventually an explosion, and stopping the energy transfer.

Therefore, the detection equipment can photograph and image the strain clamp or the splicing sleeve, and then judges whether the wire or the ground wire does not penetrate in place or the steel core is not qualified in compression joint through the obtained radiographic image, so that the power supply and electricity utilization safety is ensured.
