轨道交通车辆AC380V供电技术的研究

The research for AC380V power supply technology of rail transit vehicles

AC380V供电技术是轨道车辆用供电系统中比较成熟的一种技术,但是还是存在一定的不足之处,为了更好地利用此项供电技术,本文从系统的供电方式、负荷计算、发电机组容量确定、供电线路选择以及系统安全设计5个方面对轨道交通车辆AC380V供电设计技术进行分析,给出AC380V供电系统的设计依据,并提出了在设计中需要关注的问题。给出在设计此类供电系统时应该考虑的内容,以确保AC380V供电系统更具有合理性、安全性、可靠性。

For railway vehicles power supply system, AC380 V power supply technology is a kind of relatively mature technology, but there are still some shortcomings. In order to better use of this kind of power supply technology, The article from five aspects to analyze the system of railway vehicles AC380 V power supply. The five aspects are constituted of the power supply mode, load calculation, choice of generator capacity, choice of power supply circuit and security of system design. The design principle of the AC380 V power supply system is given, and puts forward some problems should be pay attention to during design. The article puts forward several aspects should be considered when designing the power supply system, to ensure the AC380 V power supply system more rationality, safety, reliability.
