Abstract

The invention discloses a stereoscopic rolled iron core type photovoltaic transformer with stabilizing windings, which includes a stereoscopic rolled iron core with symmetrical three-phase magnetic circuits; three-phase windings are distributed in a stereoscopic triangle, and include primary windings, secondary windings and stabilizing windings; each stabilizing winding is arranged between the secondary winding and the iron core; the stabilizing windings are mutually linked to form a stabilizing winding triangular linking structure which is not used for external power supply and has no voltage input and output; when a third subharmonic is generated on the load side, circulation in the delta connection stabilizing winding is formed, so that harmonic is effectively prevented from fleeing to a power grid. The stereoscopic rolled iron core type photovoltaic transformer has the advantages of safety, environmental protection, strong overload capacity, harmonic wave inhibition, and the like, and has the characteristics of low no-load loss and noise, small magnetizing current and size, light weight, attractive appearance and the like.

Description

A kind of three dimensional wound core photovoltaic transformer with stablizing winding
Technical field
The invention belongs to the technical field of power equipment, specifically refer to a kind of three dimensional wound core photovoltaic transformer with stablizing winding.
Background technology
Solar energy power generating has become the topmost generation mode of some developed countries, in recent years also development is rapid in China, in this new forms of energy industry, all be the transformer of y wiring for high and low pressure side, owing to itself do not have the passage of 3 grades of 3 multiple harmonic waves, so in case load side has 3 subharmonic to produce, will be directly delivered to the high-pressure side, affect the power supply quality of electric power system, 3 subharmonic also can directly enter load simultaneously, cause equipment heating.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of energy establishment harmonic wave scurry into the three dimensional wound core photovoltaic transformer that the electrical network band is stablized winding.
The present invention solves the technical scheme that its problem adopts:
A kind of three dimensional wound core photovoltaic transformer with stablizing winding, comprise the three dimensional wound core that three-phase magnetic circuit is symmetrical, being respectively 3-D triangle distributes and to be arranged on three phase windings on the three dimensional wound core, the single-phase winding of each of described three phase windings comprises winding and secondary winding, each single-phase winding also comprises stable winding, described stable winding is arranged between secondary winding and the iron core, interconnects between three stable windings to form to stablize winding delta connection structure.
Owing between secondary winding and iron core, being provided with stable winding, and interconnect between the stable winding to consist of and stablize winding delta connection structure, described leg-of-mutton stable winding is supplying power for outside not, there are not the input and output of voltage, when load side has 3 subharmonic to produce, can in the stable winding of delta connection, form circulation, thus establishment harmonic wave scurry into electrical network.It is strong that the present invention has safety, environmental protection, overload capacity, suppresses outside the advantage such as harmonic wave, the characteristics such as also have no-load loss, exciting curent is little, and noise is low, and volume is little, and is lightweight, aesthetic in appearance.
Further, be provided with electrostatic shielding between a described winding and the secondary winding.By being provided with electrostatic shielding, can effectively having suppressed second harmonic and scurry into electrical network.
Further, the first head and tail head of described secondary winding and stable winding all is arranged on the end of winding, and is arranged on leg-of-mutton each limit.This design greatly facilitates secondary winding and connects with the lead-in wire of being connected winding, has effectively saved the locational space of transformer, thereby has made whole product more compact.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing and example.
Fig. 1 is the structural representation that band is stablized the three dimensional wound core photovoltaic transformer of winding;
Fig. 2 is three dimensional wound core photovoltaic Transformer Winding and the lead-in wire schematic diagram that band is stablized winding.
Embodiment
With reference to Fig. 1-Fig. 2, a kind of three dimensional wound core photovoltaic transformer with stablizing winding of the present invention, comprise the symmetrical three dimensional wound core of three-phase magnetic circuit 1, being respectively 3-D triangle distributes and to be arranged on three phase windings 2 on the three dimensional wound core 1, the single-phase winding 3 of each of described three phase windings 2 comprises winding 4 and secondary winding 5, each single-phase winding 3 also comprises stablizes winding 6, described stable winding 6 is arranged between secondary winding 5 and the iron core, interconnect between three stable windings 6 to form and stablize winding delta connection structure, be provided with electrostatic shielding 7 between a described winding 4 and the secondary winding 5.Wherein said single-phase winding 3 from the inside to the outside structure is followed successively by: unshakable in one's determination-as to stablize winding 4 of winding 6-secondary winding 5-electrostatic shielding 7-.
Owing between secondary winding 5 and iron core, being provided with and stablizing winding 6, and interconnect between the stable winding 6 to consist of and stablize winding delta connection structure, described leg-of-mutton stable winding 6 is supplying power for outside not, there are not the input and output of voltage, when load side has 3 subharmonic to produce, can in the stable winding 6 of delta connection, form circulation, thus establishment harmonic wave scurry into electrical network.And by being provided with electrostatic shielding 7, can effectively having suppressed second harmonic and scurry into electrical network.It is strong that the present invention has safety, environmental protection, overload capacity, suppresses outside the advantage such as harmonic wave, the characteristics such as also have no-load loss, exciting curent is little, and noise is low, and volume is little, and is lightweight, aesthetic in appearance.
Further, the first head and tail head of described secondary winding 5 and stable winding 6 all is arranged on the end of winding, and is arranged on leg-of-mutton each limit.This design greatly facilitates secondary winding 5 and connects with the lead-in wire of being connected winding 6, has effectively saved the locational space of transformer, thereby has made whole product more compact.
The above is preferred embodiment of the present invention, and the present invention is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present invention with identical means, all should belong to protection scope of the present invention.
