摘　　要：通过对配电变压器采用Yyn0或Dyn11不同方式接线运行,找出当变压器发生单相短路或接地故障时,对不同接线的变压器进行过流保护计算分析,并制定出正确配置过流保护的基本原则。From analysis of distribution transformer under different connecting ways such as YynO or Dyn11, the paper gives the analysis and calculation of over current protection for transformer under different connecting ways when there are single- phase source short--circuit faults or single--phase- to- ground faults. The fundamental principles on correct selection and configuration of over current protection for distribution transformers are also given.
