摘　　要：列举出工程建设中遇到的因有载调压抽头不匹配导致可能不满足变压器并联运行条件的实例,对此进行有关环流和负荷失配率计算分析,比照有关导则的标准和条文,判断得出该工程满足并联运行条件,得出结论:对类似问题均需具体计算分析后再作出判断。As the transformers are with OLTC （on kind tap changer） and its taps are miss-match each other, so that the condition for parallel connection operation couldn＇t met by them. In this article, ticking off an examples barged up against in engineering construction, the author calculated/analyzed its circle current and load miss-match rate according to the standard/clauses of relative guide rule, estimated the condition for parallel connection operation would be still met in this case, and get a conclusion： the estimation of similar problem should be made after specific calculation/analysis.
