Features:
♦ Save equipment space. On a three-phase three-column iron core, each column is equipped with more than two sets of high and low voltage coils, which can be used in a single group (set) or multiple groups (sets) at the same time;
♦ The transformer has more than two groups of low-voltage coils, each group can be used alone or in parallel, and the coils have a large short-circuit impedance;
♦ It is usually used for AC-AC variable frequency speed-regulating motors in steel mills or connected to DC motors after rectification. The wiring mode of "one change to multiple machines" or "multiple machines to one" can be adopted.
