    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。

    Abstract:

    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.
