城市轨道交通牵引供电系统变电所直流主接线方案研究

Study on DC Main Wiring Scheme of Traction Power Supply System Substation for Transit

城市轨道交通牵引供电系统变电所直流主接线形式多样,为确定北京轨道交通供电系统更适用的直流主接线型式,对目前国内已经采用和可能采用的几种主接线型式进行分析、研究。分析内容包括直流系统的母线构成方案、越区开关的型式选择等。文章亦可为国内同类工程方案选择提供参考。

Urban rail transit traction power supply system substation has different main wiring forms for DC in the transformer substation. In order to determine a more suitable solution for the DC main wiring type for Beijing rail transit power supply system, the current domestic adoption and possible use of several main types is analyzed and studied. The content includes the structure of the bus bar of the DC system, and the selection of handover switchgear type. This paper also provides a reference for the domestic similar engineering scheme.
