Abstract
The invention discloses a coil of a combined transformer for photovoltaic power generation. The coil is composed of a high-voltage coil body and a low-voltage coil body, wherein the high-voltage coil body is of a sectional layered structure, and the low-voltage coil body is of a structure formed by winding two strands of wires in a spiral mode. Because the high-voltage coil body of the coil is of the sectional layered structure, voltage between layers can be reduced, and the coil has the advantages of being high in filling coefficient, good in impact property and the like; because the low-voltage coil body of the coil is of the structure formed by winding the two strands of wires in the spiral mode and is a double-voltage coil body, the low-voltage coil body does not need axial split and is high in coupling degree, and the coil further has the advantages of being small in size, low in cost and the like.
Description
Technical field
The present invention relates to field transformer, particularly a kind of coil of combined type transformer for photovoltaic generation.
Background technology
Photovoltaic generation, as a kind of clean production of energy mode, is at home and abroad developed rapidly.Photovoltaic generation generally adopts combined transformer.Development along with photovoltaic generation, existing combined transformer more and more can not meet the growing power reguirements of photovoltaic generation, therefore industry has proposed new requirement to combined transformer, particularly the coil of combined transformer has been proposed to special performance requirement.
Summary of the invention
The object of the present invention is to provide a kind of activity coefficient high, impact property is good, is coupled very good, and coil dimension is little, the coil of the combined type transformer for photovoltaic generation that cost is low.
Technical scheme of the present invention is as follows:
A coil for combined type transformer for photovoltaic generation, is comprised of high-tension coil and low-voltage coil, and described high-tension coil is segmented layered structure, and described low-voltage coil is that two strands of wires are by spiral winding structure.
Useful technique effect of the present invention is:
The advantages such as high-tension coil of the present invention adopts segmented layered structure, can reduce voltage between layers, has activity coefficient high, and impact property is good; Low-voltage coil of the present invention adopts two strands of wires press sped structure coiling, and low pressure be pair voltages, and low-voltage coil does not need axial split and is coupled very well, has coil dimension little, low cost and other advantages.
Advantage of the present invention will provide in embodiment description partly below, and part will become obviously from the following description, or recognize by practice of the present invention.
Accompanying drawing explanation
Fig. 1 is the structural representation of high-tension coil of the present invention.
Fig. 2 is the structural representation of low-voltage coil of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
The present invention is comprised of high-tension coil, low-voltage coil two parts.As shown in Figure 1, high-tension coil of the present invention adopts segmented layered structure, and upper strata is epimere, and lower floor is hypomere.This structure can reduce voltage between layers, and activity coefficient is high, and impact property is good.As shown in Figure 2, low-voltage coil of the present invention is that by sped structure coiling, one end of two strands of wires is a1(b1, c1 to two strands of wires (low-voltage coil is two voltage)) and a2(b2, c2), the other end of two strands of wires is x1(y1, z1) and x2(y2, z2).Adopt this structure low-voltage coil do not need axial split and coupling very good, coil dimension is little, cost is low.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate without departing from the basic idea of the present invention, within all should thinking and being included in protection scope of the present invention.
