Y_0／△一5与Y_0／△一11变压器的并列运行

Y_0/△一5 AND Y_0/△一11 TRANSFORMER SHUNT OPERATION

变压器并列运行的条件之一是结线组别相同。因此，Ｙ＿０／△一５结线的变压器不能与Ｙ＿０／△一１１结线的变压器并列运行，但是在不改变变压器内部结构及结线的情况下，采用双交心接线，即改变Ｙ＿０／△一５变压器输入、输出电压的相序，就可以与Ｙ＿０／△一１１变压器并列运行。

One of the conditions of transformers shunt operation is that the groups of connecting wires are the same so that the shunt operation of a Y0/△一5 trans-former and a Y0/△一11 transformer is not allowed.But in this case the shunt ope ration lnay be allowed if double cross-junction be adopted,i.e,by clianging the output and input voltage phase order of Y0/△一5 transformer,and unnecessarily changing it's inside constructiOn and connecting wires.
