Abstract
The utility model relates to an iron-core transformer. The transformer comprises a main iron core wrapped with an output side coil, wherein an input side coil is coated outside the output side coil; a primary iron core is arranged between the input side coil and the output side coil; four to twelve air gaps are distributed on a secondary iron core and are formed by arranging insulating boards and insulating paper in segments segmented by the iron core; the transformer also comprises a connecting channel steel and a base; the connecting channel steel is arranged at the upper end of the transformer; the base is arranged at the lower end of the transformer; and the iron core and coil parts are fixedly fixed by tensioning screws on two sides. According to utility model, the secondary iron core is arranged between the input side and the output side of the transformer, so that the input side of the transformer is equivalent to a built-in inductor; and therefore, the original electric reactor used before can be replaced, and the transformer has the voltage transformation and filtering functions of the original transformer and electric reactor simultaneously.
Description
Technical field
The utility model relates to a kind of transformer, relates in particular to a kind of appendiron core transformer.
Background technology
Existing photovoltaic generating system has very high requirement to efficient and volume usually; The photovoltaic inversion system need respectively transformer be set and reactor uses for system; Loss is bigger, has influenced whole rate, and because transformer and reactor are set respectively; The shared volume of this system is also bigger, is difficult for transplanting.
The utility model content
The purpose of the utility model provides and a kind of transformer and reactor is united two into one, to reduce the charged sense transformer of transformer and reactor loss and volume.
The concrete technical scheme of the utility model is following:
A kind of appendiron core transformer, this transformer comprise that one is wrapped with the main iron core of outlet side coil, and this outlet side coil is wrapped with an input side coil, are provided with one time iron core between this input side coil and outlet side coil.
Further, be laid with four～12 air gaps on said iron core.
Further, the air gap on said iron core is through placing insulation board and insulating paper formation in the segmentation of cutting apart at iron core.
Further, said transformer comprises that also one connects channel-section steel and base, connects channel-section steel and is located at the transformer upper end, and base is located at the transformer lower end, and two side compression transformers are fixed.
Further, be strained and fixed through screw rod between said connection channel-section steel and said base.
Further, said screw rod is located between the main iron core outside or main iron core and the inferior iron core or the inferior iron core outside.
Further, said screw rod material is a stainless steel.
The beneficial effect of the utility model is:
This use is novel owing between transformer input side and outlet side, place time iron core; Be laid with four～12 air gaps on the inferior iron core; Make the input side of transformer be equivalent to an inductance built-in; The reactor that so then can replace original required use, this transformer just have the transformation of an original transformer and a reactor and the function of filtering simultaneously.
The transformer of this charged sense unites two into one transformer and reactor, has dwindled the required volume that accounts for of original transformer and reactor greatly, and has reduced loss.

Embodiment
Like Fig. 1～shown in Figure 2, be front, the reverse view of the utility model embodiment, the utility model appendiron core transformer; Comprise an E type main iron core 5; The outer outlet side coils 2 that are wound with of main iron core 5, in be enclosed with E type main iron core 5 outlet side coil 2 same E types time iron core 6 be adjacent to, form the E sections core of a composite construction; The E sections core outer felt of this composite construction is wound with input side coil 1, constitutes transformer body.This transformer body places on the base 9, and this transformer body top is staggered fastening to connect with transformer body by connecting channel-section steel 8, connects channel-section steel 8 both sides and connects with base 9 through screw rod 10, with tension, fixing whole transformer body.In the present embodiment; Be provided with 6 screw rods altogether; Every group of 3 screw rod divides to be done two and is mounted in two spaces of end portion of E type transformer body; These two groups of screw rods are embarked on journey in twos, and this triplex row screw rod parallel position lays respectively between the main iron core outside or main iron core and the inferior iron core or be stressed evenly, fastening proper to guarantee transformer body outside the inferior iron core.Input side coil 1 one sides are provided with input side outlet row 3, and outlet side coil 2 one sides are provided with outlet side outlet row 4.Said master, inferior iron core also can be other shape iron cores except that the E type.
As shown in Figure 3; Vertical cross section for the utility model; This appendiron core transformer is followed successively by main iron core 5, outlet side coil 2, input side coil 1 from the inside to the outside, is provided with time iron core 6 between the outlet side coil 2 in left side, the input side coil 1, evenly is laid with a plurality of air gaps 7 on this time iron core 6; In the present embodiment be 5, but not as limit.Shown in air gap be through placing insulation board and insulating paper formation in the segmentation of cutting apart at iron core.
Being merely the preferred embodiment of invention in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of claim of the present invention change and modification, all should be technological category of the present invention.
