【 摘 要 】

Several kinds of widely used detection technology of wire clamp on overhead lines were introduced. Although infrared temperature measurement technology can detect the overheating defects of the clamp, it is difficult to ensure the effectiveness of on-site testing due to the environmental factors, the accuracy of testing instruments, and the experience of test personnel. X-ray inspection technology can accurately measure the exact size of the steel core without damaging the wire, and find the problem of poor crimping of the clamp. According to the field test, the typical clamp defect spectrum of X-ray inspection was listed in this study. It could effectively improve the hydraulic quality detection efficiency of the strain clamp in field work. A method was proposed, to judge the inside corrosion condition of the strain clamp, and to evaluate the current conduction capability, by detecting the current on the clamp and the wire.
