对QJ35变比电桥中极性开关位置的探讨

Discussion on Polarity Switch Position in QJ35 Variable Voltage Proportion Electric Bridge

使用QJ35变压比电桥测量非标准试验变压器变压比时,发现其使用说明书中,关于极性开关位置的说明存在问题,对其问题之处提出了个人的看法,总结了三相变压器12种联接组的组别极性,以便于试验工作者的查阅与借鉴。

When used QJ35 variable voltage proportion electric bridge to measure the variable voltage proportion of non-standard trial transformer, I found that in the specification of which, the description related to the polarity switch position had made some mistakes. I bring out my own opinion about the mistakes. And the number and polarity of twelve connection of the three phase transformer is concluded in this paper. Which is convenient for operator to consult and use for reference.
