在英明领袖华主席抓纲治国伟大战略决策和党的十一大精神鼓舞下,我专业和柳州、沈阳铁路局的有关单位共同接受铁道部研制大功率可控硅直——交逆变供电车的科研任务,从今年五月份起,结合供电74级学员毕业实践,首先进行了50千瓦可控硅三相工频逆变器的研制工作。至十月十七日本装置已通过满负荷稳定运行试验,工作状态良好。本装置采用水冷式快速可控硅组成逆变桥路,输入直流电压500伏,输出三相交流线电压为400伏,经过三相交流滤波器后,其电压波形为正弦波。交流电频率为工频制。
Encouraged by the great leadership strategy of China, the wise leader, and the spirit of the 11th CPC National Congress, I specialized in cooperating with relevant agencies of Liuzhou and Shenyang Railway Administration in the development of high-power thyristor direct- Research task, starting from May this year, combined with the graduation practice of 74 students in power supply, first conducted a 50 kW SCR three-phase power frequency inverter development work. To October 17 this device has been running at full capacity and stability test, working in good condition. The device adopts a water-cooled fast thyristor to form an inverter bridge. The input DC voltage is 500V and the output three-phase AC line voltage is 400V. After passing through the three-phase AC filter, the voltage waveform is a sine wave. AC frequency frequency system.
