Abstract
The utility model relates to a multi-phase transformer, belonging to the field of power equipment and comprising an iron core with a ring-shaped magnetic path; and the iron core is provided with primary windings and secondary windings. The multi-phase transformer is characterized in that the iron core is provided with four to sixteen winding poles, each winding pole is respectively provided with the primary winding and the secondary winding, each primary winding is respectively provided with a wiring terminal, and each secondary winding is respectively provided with the wiring terminal. By arranging the plurality of winding poles on the iron core to form the ring-shaped magnetic path, the winding pole is respectively provided with the primary winding and the secondary winding, each winding is provided with the wiring terminal, and the windings can be connected into a star-connecting structure or an angle-connecting structure according to needs; and the formed multi-phase transformer has less flux leakage, high transformation efficiency, energy conservation, simple structure, convenient manufacture and wide application range and the like.
Description
Technical field
The utility model provides a kind of polyphase transformer, belongs to field of electrical equipment.
Background technology
Existing transformer mostly is single-phase transformer, two phase transformer and three-phase transformer, is used for general single-phase family or factory's electricity consumption.But some special occasions generating, electricity consumption meeting run into heterogeneous.Existing solution generally is to be direct current by rectification earlier with heterogeneous generating, and another mistake becomes three-phase electricity, uploads electrical network; And use heterogeneous when electricity, and heterogeneous electricity need be converted into three-phase electricity, carry out again using after the transformation.Wherein phase-splitting technology and balancing technique are difficult to grasp, and electronic component damages easily, and equipment is many, and loss is big, use inconvenience, and cost is higher.
The utility model content
According to above deficiency of the prior art, problem to be solved in the utility model is: provide a kind of making simple, the polyphase transformer that loss is few.
The technical scheme that its technical problem that solves the utility model adopts is: polyphase transformer, comprise iron core with annular magnetic path, iron core is provided with winding and secondary winding, it is characterized in that iron core is provided with 4-16 wrapping post, winding and secondary winding are set respectively on each wrapping post, each winding is provided with binding post respectively, and each secondary winding is provided with binding post respectively.
During use, the binding post of a winding connects the polyphase source line of input, and the binding post of secondary winding connects the polyphase source line of output and supplies with heterogeneous electrical equipment use.4-16 wrapping post can be realized the transformation demand of 4-16 phase as required.
Wherein preferred version is:
Described iron core is a rectangle structure, between the upper beam of iron core and the underbeam wrapping post is set.Its iron core is a laminated.
Also having a kind of iron core is cage-shaped structure, wrapping post be arranged on cage-shaped structure around.Therefore its center magnetic flux phasor and be zero both can be provided with a joint pin, also can omit.
The beneficial effect that the utility model polyphase transformer is had is: by a plurality of wrapping posts are set on iron core, form the flux path of annular, winding and secondary winding are set respectively on wrapping post, each winding is provided with binding post, can as required winding be connected into star access node structure or corner connection structure, form polyphase transformer.The utility model leakage field is less, and transformation efficient height is energy-conservation, and simple in structure, easy to make, applied range.
Description of drawings
Fig. 1 is the structural representation of embodiment 1 of the present utility model,
Fig. 2 is the structural representation of embodiment 2 of the present utility model,
Wherein: 1, iron core 2, winding 3,5, binding post 4, wrapping post 6, secondary winding.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Embodiment 1:
As shown in Figure 1, iron core 1 is provided with 4-16 wrapping post 4, and winding 2 and secondary winding 6 are set respectively on each wrapping post 4.Each winding 2 is provided with binding post 3 respectively, and each secondary winding 6 is provided with binding post 5 respectively.
The quantity of wrapping post 4 is provided with as required.
Embodiment 2:
As shown in Figure 2, iron core 1 is a cage-shaped structure, wrapping post 4 be provided with cage-shaped structure around.
Operation principle and process:
During use, the binding post 3 of a winding 2 connects the polyphase source line of input, and the polyphase source line that the binding post 5 of secondary winding 6 connects output is supplied with heterogeneous electrical equipment and used.Its transformation principle and common single-phase, three-phase transformer is identical.
