摘　　要：当前高速铁路建设飞速发展,不同线路的牵引变电所回流入所线缆接入设计方案多样,根据实际测试得到牵引回流分布差异较大。本文从线缆的接入方式、接入位置、材质、规格等方面进行试验分析,得出牵引变电所回流入所线缆接入线路的优化方式,为线路回流得出最佳的线缆接入设计方案,并从回流入所线缆接入方式的角度为线路回流异常问题提供整改措施。At present,with the rapid development of high-speed railway construction,there are various design schemes for cables of different routes for traction return current accessed to posts,and there are great differences for actually tested distribution of traction return current.The paper,on the basis of test and analysis of access modes,access locations,materials and specifications of the cables,obtains the means for optimization of return current cable routes accessed to the traction substation,finalizes the optimized cable access scheme for return current of the line,provides modification measures on the abnormal return current of the line with consideration of return current cables accessed to the posts.
