电力变压器绕组Y,yn和Y,zn联接法的比较

Comparison between Reel-Y, yn and Reel-Y, zn of Transformers

对电力变压器绕组的Y,yn和Y,zn联接法从耐雷性能、三相负荷不平衡时运行情况、三次谐波、技术经济指标等方面作了详尽的分析比较,指出Y,zn11变压器具有Y,yn11变压器不可比拟的一些优点,但其价格较高,因此应权衡利弊加以应用。

Through comparison and analysis of the Reel-Y ,yn and Reel-Y,zn of transformers, the writer points out that Y,zn11 electric transformer has big advantages over Y, yn11 transformer, but we should consider it before we use it because of its high price.
