目前我国电气化铁路广泛采用工频单相交流制,伴随着我国铁路高速重载化的发展和电气化铁路规模的扩大,尤其是客运专线的发展,暴露出了许多问题。文章通过对杂散电流、弓网系统使用寿命等分析,采用高压直流牵引供电(DC35kv)可以很好的解决这一疑难问题,在以后将被应用得越来越广泛。
At present, China’s electrified railway widely adopts single-phase AC power frequency system. Along with the development of China’s railway high-speed heavy-load and the expansion of electrified railway, especially the development of passenger dedicated line, many problems have been exposed. The article through the stray current, bow network system service life analysis, the use of high-voltage DC traction power supply (DC35kv) can be a good solution to this difficult problem, will be more and more widely used in the future.
