Description
Technical field
The present invention relates to low-voltage power supply field, specifically one and have load current limliting constant voltage box type transformer.
Background technology
Transformator low pressure electricity consumption in life the most ordinary, but be all simple change voltage, how to provide a kind of right
Outer simultaneously provide one-way communication electricity, unidirectional current, three-phase alternating current box type transformer to be convenient for people to use, using electricity wisely simultaneously
Considerable thing.
Summary of the invention
The technical problem to be solved is: one has load current limliting constant voltage box type transformer, including being arranged on chest
In order electrical connection commutator, inverter, current-limiting impedance, three-dimensional winding iron core autotransformer,
As a kind of optimal way: externally draw unidirectional current output on commutator.
As a kind of optimal way: the outfan of three-dimensional winding iron core autotransformer is the different voltage of external offer
Multi-tap winding.
The invention has the beneficial effects as follows: in box type transformer, utilize the characteristic of current-limiting reactor, surge can be absorbed, thus
Sluggish heavy current impact, reduces system instantaneous pressure drop, improves system stability, and serves the effect of filtering, improves
The power factor of system, protects the safety of three-dimensional winding iron core autotransformer simultaneously；The excitation utilizing three-dimensional winding iron core balances
Mode and construction features, reach mutual balanced action in magnetic potential in three-phase, make the voltage flowing in electrical equipment be put down
Weighing apparatus and stable thus reach the purpose of power saving.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Wherein, 1, commutator, 2, inverter, 3, current-limiting impedance, 4, the input of three-dimensional winding iron core autotransformer, 5, three-dimensional winding
Iron core autotransformer outfan, 6, unidirectional current output.
Detailed description of the invention
As it is shown in figure 1, the present invention has load current limliting constant voltage box type transformer can externally export unidirectional current, three-phase alternating current
With one-way communication electricity, the output for alternating voltage is all to be exported by three-dimensional winding iron core autotransformer, can pass through
Change the number of turn and the connected mode of multi-tap winding, thus the output in the most different voltage AC source is provided.
Due to excitation balance mode and the construction features of three-dimensional winding iron core in the present invention, reach the most flat in magnetic potential in three-phase
Weighing apparatus effect, makes the voltage flowing in electrical equipment be balanced and stablizes thus reach the purpose of power saving；Simultaneously as string
Join current-limiting reactor, can absorb surge, thus sluggish heavy current impact, reduce system instantaneous pressure drop, improve system stability
Property, and serve the effect of filtering, improve the power factor of system.
