Analysis of the Main Points of Stray Current Protection Design of Urban Rail Transit based on the Requirements of "Project Specification"
Firstly,this paper makes a comparative analysis of different stray current specifications of urban rail transit,especially the differences between the project specifications and the previous industry standards and national standards.Secondly,the difficulties in the implementation of the project specification are analyzed,and the key and difficult points of engineering design calculation and engineering implementation are analyzed respectively.The calculation principles for the transition resistance value of running rail and the average value of traction reflux in the peak hour calculation interval are put forward.Finally,a specific scheme for stray current corrosion protection design is proposed,which involves the setting scheme of responsive conduction device and the optimization scheme of rail potential limiting device protection setting.
