摘要
近年修订的各种电气设计规范中，对于三相不平衡负荷配电系中的配电变压器绕组结线方式推荐采用Ｄ，ｙｎ１１，而不是Ｙ，ｙｎ０．文中从两种结线方式在空载、不平衡负载、单相短路和负载时，各种运行方式下的性能比较中得出Ｄ，ｙｎ１１与Ｙ，ｙｎ０优越。
This paper presents that D,yn11 is recommended as the connection mode of dis-tribution transformer in distribution system with three-phase unbalanced loads,and Y,yn0 is not inthe electric design standards modified in recent years.The performance comparison between D,yn11and Y,yn0 under the operating condition of no load,unbalanced load,single-phase short are made.The D,yn11 is better than Y,yn0.
