The overlap type neutral section is an important part of OCS of high-speed railway,and it is used for electrical and mechanical separation of OCS.With regard to the typical case of scratching of insulator chains by pantograph at overlap type neutral section,analysis is made by application of theory of natural uplift of wire suspension,countermeasures for prevention of faults and scheme for optimized arrangement of overlap type neutral section are put forward,providing reference for optimized arrangement of overlap type neutral sections for high-speed railways.
