Research on Near Field Magnetic Field Probe for Partial Discharge Detection of Overhead Line
摘要
Abstract
Partial discharge detection is often used to judge the operation of power system.On overhead lines,if partial discharge oc-curs,there are potential safety hazards such as polluted insulators,aging,line strand breakage,tree and building contact with transmis-sion lines.If not detected and removed in time,further development of partial discharge may lead to serious accidents.To solve these problems,a new near-field magnetic field probe is designed to detect the electromagnetic wave signal generated by partial discharge on overhead lines.The main structure of the probe designed is a small ring.The probe is mainly installed on the unmanned aerial vehicle to carry out short distance partial discharge detection on overhead lines.The final size of the probe is 166 mm long,104 mm wide,2 mm thick and 30 g heavy.Finally,the performance of the probe is verified by building a partial discharge test platform.关键词
