箱式直流牵引变电站在城际轨道交通中的应用

Application of E-house DC Traction Substation in Intercity Rail Transit

城际轨道交通通常采用直流牵引供电制式。由于直流牵引变电站的供电距离较短,需在站间距较大的沿线区间设置牵引变电站。结合直流牵引变电站的供电设备组成,提出了对应箱式变电站各功能单元的划分方案,并成功应用于南京宁高城际轨道交通工程。预装箱式变电站具备占地面积小、施工周期短的优点,随着技术不断发展,预装箱式变电站在城际轨道交通领域应用前景广阔。

Intercity rail transit usually adopts DC traction power supply system.Due to the short power supply distance of DC traction substation,it is necessary to set up traction substations in the sections along the line with large distance between stations.Considering the composition of power supply equipment at DC traction substation,a scheme for dividing the functional units of the corresponding E-houses is proposed,which has been successfully applied to Nanjing-Gaochun intercity rail transit project.The E-house features small floor space and short construction period,and with the continuous development of technology,it will have a broad application prospect in the field of intercity rail transit.
