不同组别类型的变压器并联运行的研讨

Study of parallel operation for transformer in different type of sets

分2种情况分析讨论了不同组别类型的变压器并联运行的问题,得出Y/△联接与△/Y联接的两变压器,只要它们的标号(奇数)相同,则可并联运行;Y/Y联接与△/△联接的两变压器,只要它们的标号(偶数)相同,则可并联运行.通过实验室验证与实际应用,收到了良好的效果.这样拓宽了变压器并联运行的范围.

According to two aspects, this paper analyzed and discussed the parallel operation of the transformer. It obtained that two transformers of the Y/△ connection with △/Y connection can be in parallel operation, as long as their label （odd） is the same; and that two transformers of the Y/Y connection with △/△ connection can be in parallel operation, as long as their label （even） is the same. Through laboratory test and practical application, good results are obtained. This broadened the scope of the transformer parallel operation.
