便携式多功能机车充电机研究及应用分析

Research and Application Analysis of Portable Multifunctional Locomotive Charger

针对蓄电池组电量低导致机车无法启动(升弓)的问题,以便携式大功率高频开关电源技术为基础,设计了一套具有大功率快充、电力内燃机车通用、便携易操作、充电状态智能显示等特性的多功能充电机。该充电机利用220 V电源,实现机车蓄电池组智能快充的功能,起到机车灵活充电和处理蓄电池组临时故障的作用。

In response to the problem of low battery pack power causing the locomotive to be unable to start(raise the pantograph),based on the portable high-power high-frequency switching power supply technology,a multi-functional charger with characteristics such as high-power fast charging,universal use for electric diesel locomotives,portability and easy operation,and intelligent display of charging status has been designed.The charger utilizes a 220 V power supply to achieve intelligent and fast charging of locomotive battery packs,playing a flexible role in locomotive charging and handling temporary battery pack faults.
