摘要
换流变压器是直流输电工程中的关键设备,文中通过对单级12脉动换流变压器进行EMTDC建模,分析了其阀侧绕组绝缘承受的电压类型,研究结果表明阀侧绕组承受的是一种由直流电压分量、交流电压分量、谐波电压分量以及换相脉冲构成的复合电压。通过对换流变压器阀侧绕组承受的复合电压进行分析,对其各个分量的含量水平进行了分析计算。
Converter transformer is the key equipment of DC transmission engineering. The EMTDC simulation model of single pole 12 pulse system is created in this paper. The voltage type of converter transformer valve side insulation is analyzed. The results show that the oil-paper insulation of the valve side windings of converter transformers withstands several components such as DC,AC, harmonics and the commutation pulse. The components content level of compound voltage also analysis in this paper based on the analysis of the compound voltage of the converter transformer valve side windings.
