摘要
高速铁路电力贯通线路分为10 kV电力综合负荷贯通线路和一级负荷贯通线路,需全线采用全电缆线路.当采用全电缆线路时,电缆线路故障的精准定位对于铁路运输的安全性和可靠性意义重大.本文结合国内外电力电缆线路故障定位的现状,对行波测距定位原理进行分析,详细分析了单端行波定位以及双端行波定位的原理及优缺性,并对行波测距的关键技术进行了研究;最后结合高速铁路电力贯通电缆线路的特点,分析了行波测距定位方法在电力贯通电缆线路中的应用.
It is required to adopt a full cable line for hish-speed railway power transmission line with 10 kV power integrated load and primary load respectively.The precise positioning of power cable line faults in high-speed railway is of great significance for the safety and reliability of railway transportation.The author discussed the current situation of fault location at home and abroad,analyzed the principle of traveling wave ranging and single-ended traveling wave positioning as well as double-ended one,and compared the superiority and deficiency.The key technologies were researched.Finally,combined with the characteristics of high-speed railway power through cable lines,the feasibility of the traveling wave ranging method for positioning in power-through cable lines Was studied.
