To cope with the issue that the traditional metro OCS power supply compartment design scheme cannot meet the requirements of maintaining the line's capacity to the maximum extent in case of power supply compartment failure or bad weather affecting the normal operation of the line,relying on the Beijing metro line 14,this article carries out in-depth analysis of its power supply compartment layout,and puts forward two kinds of improved design scheme,aiming to provide universally applicable suggestions for the design optimization of the OCS power supply compartment layout of subsequent urban rail transit.In the process of analysis,this article comprehensively weighs the advantages and disadvantages,the complexity of applying them to the transformation of existing lines and the economic benefits and other dimensions of the two design schemes,with the aim of clarifying and optimizing the final design scheme.This scheme should ensure that in the event of a metro line failure,it can effectively reduce the scope of influence of the failure,maximize the maintenance of transport capacity,so as to ensure the safe and reliable operation of the power supply system of rail transit.
