Distribution transformer is applied to to the stay of new material, has reduced the temperature rise, has improved the efficiency of transformer, reduce overall dimension, improved installation conveying efficiency, practiced thrift raw and other materials, reduce cost has improved the profit of product.
Description
Technical field
This utility model belongs to transformer equipment field, relates to a kind of distribution transformer.
Background technology
Present stage, the universal temperature rise of distribution transformer is relatively big, and power transformation efficiency is low.Transformator overall dimensions is the biggest；Not side
Just installation and transportation.The problem of coil method is not to space Appropriate application, and manufacturing cost is higher.Present stage adopts when manufacturing coil
Using insulating board stay, the width of this stay generally 8mm minimum can accomplish 6mm, and thickness is 3 millimeters, and stay size width causes
Oil duct limited area between stay, affects radiating effect, and stay cost is high.
Summary of the invention
This utility model is in order to make up the deficiencies in the prior art, it is provided that a kind of size is little, temperature rise is low, cost-effective joins
Piezoelectric transformer.
This utility model is achieved by the following technical solution:
Distribution transformer of the present utility model, it is characterised in that: include high-tension coil and the low-voltage line being arranged in casing
Circle, it is characterised in that: low-voltage coil and high-tension coil are radially sleeved in iron core column successively, are also placed with coolant in casing, low
In line ball circle, between the conductor winding layer of every radially adjoining, all pad is provided with insulating barrier, the conductor winding layer of every radially adjoining in high-tension coil
Between all liner has the inner side of insulating barrier, low-voltage coil and high-tension coil to be respectively equipped with interior insulation, outside is respectively equipped with external insulation,
It is fixedly installed several insulating stays parallel with iron core column in insulating barrier, between adjacent two insulating stays, reserves an axle
To through oil duct；Insulating stay uses cylindrical stay.
Insulating stay is made up of bamboo.
A diameter of 3 millimeters of insulating stay.
Iron core column cross section is rectangular.
The beneficial effects of the utility model are, simple in construction, easy to use, and the stay of this new material is applied to distribution transformer
Device, on the premise of meeting requirement of strength, when using same number of stay, substantially reduces the cross-sectional area of stay, significantly
Increase the cross-sectional area of oil duct, well add cooling effect, reduce temperature rise, improve the efficiency of transformator；Reduce
Overall dimensions, improves installation and transportation efficiency；Save raw material, reduced cost, improve the profit of product.
Accompanying drawing explanation
Fig. 1,2 it is the front view of existing structure coil, top view schematic diagram, Fig. 3,4 is the master of this utility model coil
View, top view schematic diagram.
1, the conductor of coil and insulating barrier；2, insulating stay；3, interior insulation；4, oil duct.A, the first head of coil, x, line
The tail head of circle.
Detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present utility model.
Distribution transformer of the present utility model, including the high-tension coil being arranged in casing and low-voltage coil, low-voltage coil
Radially being sleeved on successively in iron core column with high-tension coil, be also placed with coolant in casing, in low-voltage coil, every radially adjoining leads
Between body winding layer, all pad is provided with insulating barrier, and in high-tension coil, between the conductor winding layer of every radially adjoining, equal liner has insulating barrier, low
The inner side of line ball circle and high-tension coil is respectively equipped with interior insulation 3, outside is respectively equipped with external insulation, if being fixedly installed in insulating barrier
A dry insulating stay 2 parallel with iron core column, reserve between adjacent two insulating stays one axially through oil duct 4；Insulation
Stay uses cylindrical stay.
Insulating stay is made up of bamboo.
A diameter of 3 millimeters of insulating stay.
Iron core column cross section is rectangular.
Novel stay, by improving the stay of traditional transformer coil, is applied to transformer fe coil by this utility model
On.Using circle bamboo let stay inside low-voltage coil, high-tension coil, the interface between low-voltage coil, high-tension coil is still
Use insulating board stay.The circular stay that bamboo let is made significantly makes oil duct become big.Solve transformator overall dimensions big；
Temperature rise is higher；The problem that the cost of raw material is high.
Being contrasted from Fig. 1 and Fig. 2, the stay of this new material structures transformer coil and original transformer coil are not
The same.Present stage uses insulating board stay when manufacturing coil, and the width of this stay generally 8mm minimum can accomplish 6mm,
Thickness is 3 millimeters；And this utility model transformer coil uses round bamboo let as stay, a diameter of 3 millimeters of bamboo let of circle, it
It is simple to manufacture with low cost, uses it to significantly increase the area of dissipation of oil duct as seen from Figure 2, thus reduce transformation
Device temperature rise, temperature is low, and loss is the highest with regard to small transformers efficiency, the low volume that can reduce of temperature rise, cost-effective purpose.
