马坝站站场改造中接触网设计优化

Design Optimization of trolley line in reconstruction of MABA station

为充分发挥铁路货运的优势,加强铁路运输能力的运用,对马坝站进行站场改造。将马坝站9~12道共4股道由调车线改为到发线。对9~12股道进行挂网,并对站改引起的咽喉区接触网进行迁改,通过对马坝站改造接触网供电分段设计、咽喉区设计、平面布置设计优化,实现马坝站站场改造接触网设计优化,并对今后类似电气化铁路站场改造的接触网设计优化提供依据和参考。

In order to give full play to the advantages of railway freight transportation and strengthen the use of railway transportation capacity,the station yard transformation of MABA station was carried out.Four tracks of 9-12 tracks in MABA station are changed from shunting track to receiving departure track.The 9-12 station tracks are electrified,and the throat area contact network caused by the station transformation is relocated.Through the optimization of the catenary power supply segment design,throat area design,and layout design optimization of the Maba station reconstruction,the catenary design optimization of the Maba station station yard was realized,and the basis and reference are provided for the OCS design optimization in the similar electrification railway station reconstruction in the future.
