摘要
基于绝缘栅双极型晶体管(IGBT)的开关特性,通过在机械式有载调压开关中增加由IGBT和电力二极管构成的辅助切换电路,提出了一种混合式配电变压器有载调压开关结构及其参数的设计方法,所提结构在抽头切换时引入电力电子开关,利用电力电子开关的开关性能实现配变抽头的有载无弧调整。最后,在MATLAB/Simulink中搭建了混合式配电变压器有载调压开关的仿真模型,验证了所提混合式有载调压开关结构和参数设计方法的可行性。
Based on the switching characteristic of insulated gate bipolar transistor(IGBT),this paper proposes a structure and parameter design method of hybrid on-load tap changer for distribution transformer by adding an auxiliary switching circuit composed of IGBT and power diode to the mechanical on-load tap changer.The proposed structure leads power electronic switches in when the tap is switched,and realizes the on-load arcless adjustment of the distribution transformer tap by utilizing the switching performance of the power electronic switches.Finally,the simulation model of hybrid on-load tap changer for distribution transformer is built in MATLAB/Simulink,which verifies the feasibility of the proposed structure and parameter design method of hybrid on-load tap changer.
