Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure, 1 is outer layer high-tension coil, and 2 is oil duct（Air channel）, 3 is internal layer high-tension coil, and 4 is main empty path, and 5 is low pressure
Coil.
Specific embodiment
As shown in figure 1, the utility model provides a kind of continuous winding structure with longitudinal oil duct/air channel, including height
Line ball circle, low-voltage coil 5, high-tension coil, low-voltage coil 5 are sleeved on stem, are provided between high-tension coil and low-voltage coil 5
Main empty path 4, high-tension coil is separated into internal layer high-tension coil 3, outer layer high-tension coil 1, internal layer high-tension coil 3 and outer layer high-tension coil
Oil duct 2 is provided between 1.
Wherein, by the iron core stem of silicon steel sheet closed assembly（Stem）As skeleton, high-tension coil（1、3）, low-voltage coil
It is enclosed within iron core stem, then is fixedly clamped with screw rod, folder, feet.Folder and feet, are made by section bar.Dry type transformation
Device high-tension coil, low-voltage coil, copper, aluminium wire coiling.
Continuous high pressure loop construction is divided into 2 sections of coilings, longitudinal oil duct or air channel is provided with intersegmental（2）.
In oil-filled transformer, after coiling internal layer high-tension coil 3, constant spacing stay is set, then coiling outer layer
High-tension coil 1, forms oil duct 2.
In dry-type transformer, after coiling internal layer high-tension coil 3, constant spacing air flue rod is set, then coiling outer layer
High-tension coil 1, internal layer high-tension coil, outer layer high-tension coil casting epoxy resin extract air flue rod after fixing, and form longitudinal air channel
2, increase the area of dissipation of coil.
A kind of continuous winding structure with longitudinal oil duct/air channel of the present utility model, by continuous high pressure coil（1、3）
Structure is divided into 2 sections of coilings, and longitudinal oil duct is provided with intersegmental（Air channel）（2）, increase the area of dissipation of coil, improve radiating effect
Rate, makes coil temperature rise reach requirement.
The continuous winding structure is applied to each capacity of dry-type transformer section, with graded winding compared with small volume,
The low feature of material consumption, reduces production cost, 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.
