摘要
研究了空芯变压器锥形绕组的电压分布特性。运用多导体传输线理论建立锥形绕组的多导体传输线数值分析模型,推导模型等效电路中各项分布参数的求解公式,利用有限元软件求解分布参数并进行模拟计算。搭建实验平台测量绕组各匝线圈首端的电压波形,得到了匝间电压和对地电压的分布规律,实验结果与模拟计算基本吻合。研究表明:分布参数会引起电压谐振,冲击电压的上升沿在绕组首端产生匝间过电压;多导体传输线模型可对锥形变压器绕组的电压分布进行有效计算。
The multi-conductor transmission line（MTL） model used for analyzing taper winding in air-cored pulse transformer was build by multi-conductor transmission line theory. The reasoning formula of distributed parameter in its equivalent circuit were deduced, and then they were calculated by finite element method. Experiment was carried out to study the impulse voltage distribution on taper winding, such as turn-to-ground voltage and turn-to-turn voltage, the results were agreeable to that of calculation. Research indicates that distributed parameter on taper winding led to voltage oscillation during rising edge, which may create excessive voltage gradient in head of winding, the validity of MTL model is also proved.
