| 摘 要： | 冲击电压发生器充电过程中,各级电容充电电压的不均匀性直接影响发生器输出预测和控制设定的准确度,特别是输出电压高、级数多的大型发生器,各级电容充电的不均匀现象尤为突出。本文先讨论直流电压源对均匀分布参数充电回路的充电过程,计算分析各级电容充电电压之间的不均匀度。然后通过建立冲击电压发生器的EMTP仿真模型,分析并讨论充电回路元件参数、充电方法和充电时间等因素对充电电压不均匀度的影响。分析恒流充电方式、减小充电电阻以及采取合理的控制策略等技术措施对改善充电电压不均匀度的效果,通过实验验证并改进这些措施,有效的减小充电的不均匀度,提高冲击电压发生器充放电过程测量控制的准确性。

| Abstract: | During the charging process of impulse voltage generator,the charging ununiformity of stage capacitor voltages will directly influence the accuracy of output forecast and control setting of the generators.For multi-stage large generators with high output voltage,the phenomenon of charging ununiformity of stage capacitor voltages is particularly prominent.This paper analyzes the charging process of uniform distributed parameter circuits charged by DC voltage source,calculates the ununiformity of the charging... |
