摘要
针对煤矿直流电机车照明及响笛的供电问题 ,研制并开发出一套性价比高、适应环境能力强的电源变换器 ,从根本上解决了高电压。
In accordance with power supply problem of lighting and whistle for continuous current 1ocomotive in coal mine,we developed a power transformer with high PE,and it can adapt itself to odious circumstances.It solved high voltage and heavy current fundamentally.
