摘要
分析了三相变压器原、副绕组相电压与线电压之间的一般关系,从而概括为几个基本组别号,然后在基本组别号的基础上演化出来其他组别号。利用该方法,可以很快知道变压器组别号,而且便于作相量图,同时也可用来改变变压器连接规律来改变变压器的组别号,非常简单,实用性很强。
The paper made an analysis of the relationship between phase voltage and winding voltage of three-phase transformer primary and counter windings. The transformer unit number is summarized as several basic ones, which can evaluate other unit numbers. By adopting the method, the transformer unit number can be obtained quickly, and which also can be used to change the transformer unit number by alternating its connection pattern of the transformer. It is not only easy but also practical.
