摘要
采用理论结合实践的方法,立足震荡波局放检测的原理,分析震荡波局放检测技术的优势,通过试验分析此项技术的有效性和可行性。分析结果表明,局部放电是电缆发生绝缘故障的先兆,通过对局部放电进行检测,可提升电缆状态检修水平。
Based on the principle of shock wave partial discharge detection,the advantages of shock wave partial dis‐charge detection technology for 10 kV distribution cable lines are analyzed by combining theory with practice.The ef‐fectiveness and feasibility of this technology are analyzed through experiments.The results show that partial discharge is the precursor of cable insulation fault.By detecting partial discharge,the level of cable condition based maintenance can be improved.
