Abstract
The utility model discloses a kind of dry-type transformer with shielding, it is characterised in that it includes high-tension coil, low-voltage coil, the high-tension coil, low-voltage coil are sleeved on stem, main empty path is provided between the high-tension coil and low-voltage coil, the high-tension coil inner side is provided with metal screen layer.A kind of dry-type transformer with shielding of the present utility model, by installing metal screen layer on the inside of high-tension coil, metal screen layer reliable ground reduces spacing between high-tension coil, low-voltage coil, effectively reduces the size of high-tension coil.
Description
Technical field
The utility model is related to transformer, and in particular to a kind of dry transformer coil structure.
Background technology
At present, between the high and low pressure coil of general dry-type transformer distance between 35~40mm, be spaced it is larger, make
Obtain high-voltage line ring layer size big, materials'use amount is high.
Utility model content
The purpose of this utility model is to provide a kind of dry-type transformer with shielding, reduces voltage between high and low pressure, reduces
Insulation distance, reduces the volume of product.
It is that, up to above-mentioned purpose, the utility model provides a kind of dry-type transformer with shielding, including high-tension coil, low pressure
Coil, high-tension coil, low-voltage coil are sleeved on stem, and main empty path, high-voltage line are provided between high-tension coil and low-voltage coil
Circle inner side is provided with metal screen layer.
Further, stem is formed by silicon steel sheet closed assembly.
Yet further, metal screen layer is connected with ground wire.
In sum, the utility model has advantages below：
A kind of dry-type transformer with shielding of the present utility model, by installing metal screen layer on the inside of high-tension coil,
Metal screen layer reliable ground, reduces spacing between high-tension coil, low-voltage coil, effectively reduces the size of high-tension coil.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Wherein, 1 is high-tension coil, and 2 is metal screen layer, and 3 is main empty path, and 4 is low-voltage coil.
Specific embodiment
As shown in figure 1, the utility model provides a kind of dry-type transformer with shielding, including high-tension coil 1, low-voltage line
Circle 4, high-tension coil 1, low-voltage coil 4 are sleeved on stem, and main empty path 3 is provided between high-tension coil 1 and low-voltage coil 4, high
The inner side of line ball circle 1 sets and is provided with metal screen layer 2.
Wherein, by the iron core stem of silicon steel sheet closed assembly（Stem）Used as skeleton, high-tension coil 1, low-voltage coil 4 are enclosed within
On iron core stem, then it is fixedly clamped with screw rod, folder, feet.Folder and feet, are made by section bar.Dry-type transformer is high
Line ball circle 1, low-voltage coil 4, copper, aluminium wire coiling.
Metal screen layer 2 is laid on the inner side of high-tension coil 1 and separates high-tension coil 1 with main empty path 3, on metal screen layer 2
It is provided with terminals to connect ground connection, reduces the eddy-current loss of transformer, so as to reduce the width of transformer main empty path 3
Degree.Terminals are arranged on the inwall of metal screen layer 2, and ground wire is connected on and is placed on the terminals of main empty path 3；Or, terminals are in T words
Shape stator, installed in the outer wall of metal screen layer 2, ground wire is wound on stator, and high-tension coil 1 is by ground wire and stator pressure
Tightly on metal screen layer 2.
A kind of dry-type transformer with shielding of the present utility model, metal screen layer is installed by the inner side of high-tension coil 1
2, the reliable ground of metal screen layer 2 reduces spacing between high-tension coil 1, low-voltage coil 4, effectively reduces the chi of high-tension coil 1
It is very little.
The dry-type transformer effectively reduces voltage between high and low pressure, and insulation distance can reduce 10mm, reduce product
Volume, reduces material consumption, improves the competitiveness of product in market.
Although being described in detail to specific embodiment of the present utility model with reference to accompanying drawing, it is right to should not be construed as
The restriction of the protection domain of this patent.In the scope described by claims, those skilled in the art are without creative labor
The dynamic various modification and variation that can be made still belong to the protection domain of this patent.
