摘要
以IEC60060-3标准为基础,针对变压器感应式振荡型操作冲击电压的产生方法进行研究。在理论上分析了用变压器产生振荡型操作冲击电压的产生方法,列出了回路中元件参数的计算公式。根据公式计算的波头时间、波尾时间和频率值得到元件参数,计算机仿真结果表明所产生的波形符合IEC60060-3标准的规定,且计算公式能够准确地反映回路元件参数值与波形参数之间的关系。在仿真的基础上,在实验室采用哈弗莱RSG481冲击电压发生器对一台单相双绕组110kV变压器低压侧进行输入,在其高压侧产生感应式振荡型操作冲击电压,试验结果表明采用该方法可方便迅速、高效地在被试变压器高压侧产生符合IEC60060-3标准的振荡型操作冲击电压。
The generation method of the transformer inductive oscillating switching impulse voltage based on the IEC60060-3 standard is investigated in this paper. The circuit of the oscillating switching impulse voltage generated through transformer induction is analyzed in theory and the formulas of generation circuit parameters are presented. The generation circuit parameters can be evaluated by the time to peak,time to half-value and oscillating frequency of the oscillating switching impulse voltage waveform. The computer simulation results show that the generated waveforms meet the requirements of IEC60060-3 standard,and the formulas can accurately calculate generation circuit parameters by the oscillating switching impulse voltage waveform parameters. The experimental researches are carried out in an 110kV power transformer with a single phase and two windings by the Haefely RSG 481,and the experimental results reveal that the high voltage terminal of the power transformer can effectively generate the oscillating switching impulse voltage which satisfies the requirements of IEC60060-3 standard by the Haefely RSG 481 input to the low voltage terminal of the power transformer.
