摘　　要：通过上跨或下穿营业电气化铁路的市政涉铁工程中接触网改造设计案例的分析,阐述了由于通过营业电气化铁路区间、站场的上跨市政桥梁净空不够高,下穿市政涵洞位置无法避开接触网设备等原因,分析接触网改造的重、难点,并提出相应的接触网改造设计方案,达到尽量减小营业电气化铁路停电影响范围、减少接触网改造工程量[1]的目的。The paper expounds that the key and difficult points of the ocs-system reconstruction are analyzed, and the corresponding plan about the ocs-system reconstruction design is put forward to achieve the goal of minimizing the influence scope of power failure on business electrified railways and reducing the amount of business line reconstruction,for the reasons that the headroom of the municipal bridge over the electrified railway sections and stations is not high enough,and the position of the municipal culvert under the electrified railway sections and stations cannot avoid the catenary equipment, through the analysis of the ocs-system reconstruction design case in municipal related projects of overpassing or underpassing commercial electrified railways.
