摘要
斯科特平衡变压器因没有中性点可以直接接地，制造工艺要求较高，在我国１１０ｋＶ及以上电力系统中的应用受到限制。本文提出了这种变压器引出中性点的接线方案，并分析了其电磁变换的基本原理。
A Scott balance transformer hasn't neutral point connected to the earth, and thus requires higher technology in manufacturing. So its application is restricted in 110kV and above power system in China. In this paper a connection scheme is proposed of which a neutral point is drawned from the balance transformer, and its electromagnetism principle is also analysed.
