如果是参照SS5的去解释欧洲的机车供电,那AC1500只是单相电,直接从变压器上抽头,最多加上一个开关,没有其 ...
看了上面朋友给的关于机车供电的链接介绍,目前的新客车接受供电的能力是几种制式通吃的,能够满足几种典型电压包括空调的需求。
文章最后结尾,比较推AC400左右的供电模式:
In the future, the old RIC- voltages will be replaced by the much more cost-effective solution with 50 or 60 Hz three-phase 400/415 V (50 Hz) or 480 V (60 Hz). Three-phase is the backbone of the global electric power network and most electrical power equipment is today designed for three-phase supply; the 400/415 V 50 Hz supply is ubiquitous in 50 Hz markets, allowing the use of off-the-shelf mains electrical equipment. For example, in UK and Sweden the high-speed trains IC125 and X2000 have 50 Hz 3-phase power bus.
而天朝通过比较,认为DC600V的优点更多,更合适。两个不同的方向。
