| 摘 要： | 建立了一个由16根平行导线构成的广义四端网络表征AT供电系统模型,以沪宁高铁无锡区段某供电臂为实例,计算与分析了综合接地系统接入后对钢轨电位、牵引网阻抗、钢轨及大地回流的影响.计算数据表明,综合接地对钢轨电位的降低有显著的作用,而对牵引网阻抗的大小几乎没有影响.

| Abstract: | This paper build an AT traction power supply mode characterized with a generalized four-terminal network composeed of 16 parapllel conductor, for example of a power supply arm in Wuxi section of Shanghai-Nanjing highspeed railway, calculate and analysis the effect to rail potential, induced voltage for communication line, impedance of traction electric network, and current return of rail and earth. The calculation state that the comprehensive earthing can significantly reduce the rail potential and have alm... |
