一种新型有载分接开关可行性探究

Study on the Feasibility of a New Type on Load Tap Changer

针对现有110 kV变压器有载分接开关的不足,提出了一种基于IGBT模块的混合切换方案,解决了分接开关油室油劣化及分接开关频繁维护问题,并对其完成了初步参数造型及调试。

In view of the shortcomings of the existing 110kV transformer on load tap changer,a hybrid switching scheme based on IGBT module is proposed to solve the problems of oil deterioration in the oil chamber of the tap changer and frequent maintenance of the tap changer,and the preliminary parameter selection and commissioning are completed.
