4.4变流器4.4.1结构每列动车组上的4台牵引变流器(图11)为ABB公司的BORDLINE〇R系列。型号为CC700MS的紧凑型变流器可以用于两种电流制(表4),使得动车组既能用于AC11kV 16.7 Hz的主干网,又能用于DC的贝尔尼纳当地线路网。
4.4 Converter 4.4.1 Structure Four traction converters on each train unit (Figure 11) are ABB’s BORDLINE OR series. The compact converter model CC700MS can be used for both current systems (Table 4), enabling the EMU to be used both for AC 11kV 16.7 Hz backbone and for DC’s Bernina local line network.
