摘要
介绍城轨交流牵引供电系统的研究现状及设计条件,确定接触网标称电压的论证范围。从牵引供电系统电压损失计算方法适用性、接触网组成、钢轨电位、牵引网电压水平和最长供电距离5个方面对不同标称电压进行分析和对比,得出城轨交流牵引供电系统接触网标称电压宜选择6.0 k V。
Introduces the current status of researches and conditions of design for AC traction power supply system of urban rail transit, defines the theoretical scope of OCS nominal voltage. Analysis and comparisons are made for various nominal voltages in terms of 5 aspects of applicability of calculation methods of voltage loss of traction power supply system, composition of OCS, rail potential, traction network voltage level and maximum power supply distance, and the conclusion is obtained that 6.0 k V should be selected for the OCS nominal voltage.
