Abstract
The utility model discloses a three-phase non-phase-shift inductive voltage regulating combination apparatus, including N inductive voltage regulators. N/2 inductive voltage regulators adopt a positive-rotary magnetic field; the other N/2 inductive voltage regulators adopt a counter-rotary magnetic field.

The three-phase non-phase-shift inductive voltage regulating combination apparatus eliminates the phase shift problem of the original three-phase inductive voltage regulators in voltage regulation, easily solves the problem of zero initial voltage, and remarkably improves the linearity of the voltage regulating curve; when the capacity of a voltage regulating assembled apparatus needs improving, a voltage boosting or current boosting autoformer can be added besides adopting the project that the primary grades of the multi-voltage regulators are connected in parallel and the secondary grades of the multi-voltage regulators are connected in series, so as to further expand the capacity and expand the voltage regulating ranges or the current regulating ranges, and thus the utility model opens up a new and wide approach for manufacturing inductive voltage regulating devices with larger capacity.
