Description
technical field [0001] The invention relates to the technical field of electric power test equipment, in particular to a fretting wear test device and method for a connecting wire clip wire system. Background technique [0002] In the power system, the main line and the branch line are mostly fixed and installed by means of connecting clips. When the connecting clips realize the fixed connection of the above-mentioned wires, there are tensions between the clips and the wires, heat generated by resistance, and various external vibrations. The above-mentioned various interference factors have an impact on the fretting wear of the clamp and the wire, which is also a problem that needs to be paid attention to in the power system. In the prior art, there is no test equipment for simulating the fretting wear induced by breeze vibration of the connecting clip and the wire in the actual installation state, and cannot provide real and reliable theoretical reference data for the frett...
