It is used as power or distribution uses, a transformer can be saved, effectively reduce cost and installing space.Normal configuration is three coils
Radial concentric is distributed.
Existing three-winding transformer with split winding has a disadvantage that：
(1) low pressure mould uses two sets；
(2) radial dimension is big；
(3) impedance is big；
(4) space-consuming is big；
(5) cost is high.
Utility model content
The technical problems to be solved in the utility model be to provide it is a kind of it is simple in construction, occupy little space, three lines that cost is low
Enclose transformer with split winding.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：
A kind of three-winding transformer with split winding, including iron core, high-tension coil, low-voltage coil and the transformer bottom for installing iron core
Seat；High-tension coil is one, and low-voltage coil is two, and two low-voltage coils are setting up and down, and is axially wound on the outside of iron core, high pressure
Coil and two low-voltage coil radial concentrics are wound on the outside of low-voltage coil；High-tension coil, low-voltage coil are poured per phase with epoxy resin
Note is integrated, and the magnetic conduction body loop that iron core is wound into closing by strip magnetic conducting band is formed, the circular in cross-section of iron core or ellipse
It is circular.
In one embodiment of the present utility model, silicon rubber cushion block is provided between two low-voltage coils.
In one embodiment of the present utility model, iron core is provided with iron core folder, high-tension coil, two low-voltage coils pair
Just it is fixed on afterwards with cross-over block by fastening bolt on iron core folder.
Pass through above-mentioned technical proposal, the beneficial effects of the utility model are：
The utility model is simple in construction, occupy little space, cost is low, low pressure mould is using a set of, power supply quality and reliably
Property it is high.

20th, the transformer base 40 of low-voltage coil 30 and installation iron core；High-tension coil 20 be one, low-voltage coil 30 be two, two
Individual low-voltage coil 30 is setting up and down, and is axially wound on the outside of iron core 10, and silicon rubber cushion block 50 is provided between two low-voltage coils 30,
Improve insulating properties；For two low-voltage coils axially highly, internal-and external diameter is united for pro rate on request, profile is identical,
Two low-voltage coils use same mold, are connect in low-pressure line-outgoing by d or y connects extraction；High-tension coil 20 and two low-voltage lines
30 radial concentrics are enclosed to be wound on the outside of low-voltage coil；High-tension coil, low-voltage coil are integrated per phase with poured with epoxy resin, iron core 10
The magnetic conduction body loop that closing is wound into by strip magnetic conducting band is formed, and the circular in cross-section or ellipse of iron core, the design make
Obtain transformer noload losses and load loss is greatly lowered；Iron core 10 is provided with iron core folder 11, high-tension coil 20, two
Low-voltage coil 30 is fixed on iron core folder 11 after aligning with cross-over block 60 by fastening bolt 70.
The utility model stays upper yoke not fill when transformer core assembles, and is inserted in that two d connect or y connects low pressure in order
Coil 30, in two middle pad silicon rubber cushion blocks 50 of low-voltage coil 30, high-tension coil 20 is then inserted in, after 3 coils are aligned
It is fixed on cross-over block 60 by fastening bolt 70 on iron core folder 11.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
