Abstract

The utility model discloses a disc coil for dry -type water -cooled transformer, including stay (2), its characterized in that: stay (2) enclose into the round, and around putting inside copper pipe (1) of walking the cooling water on stay (2), two are provided with cushion (3) between stay (2) of putting copper pipe (1), two wind stay (2) and cushion (3) of putting copper pipe (1) and constitute a set of disc coil. The utility model discloses an around putting the copper pipe of walking the cooling water in inside on enclosing into the stay of round, just to wind stay and the cushions of putting the copper pipe through two and constitute a set of disc coil, cooling water, the electrically conductive integrative wind structure of water and electricity in outside are walked to component inside, can accomplish the ampere -turn balance, just have characteristics small, that filling coefficient is big, coil cooling is effectual, belong to the big current coil of low -voltage, so be applicable to the occasion of heavy current.

Description

A kind of disk-type winding for dry type water-cooling transformer
Technical field
The utility model relates to transformer technology field, specifically a kind ofly can accomplish ampere-turn equilibrium, volume is little, activity coefficient is large, coil good cooling results and be applicable to the disk-type winding for dry type water-cooling transformer of the occasion of large electric current.
Background technology
, owing to adopting traditional spiral pitch of the laps structure, therefore there is ampere-turn injustice, shortcoming that leakage reactance is larger in existing dry type water-cooling transformer.
Summary of the invention
The purpose of this utility model is the problem existing for prior art, provides a kind of and can accomplish ampere-turn equilibrium, volume is little, activity coefficient is large, coil good cooling results and be applicable to the disk-type winding for dry type water-cooling transformer of the occasion of large electric current.
The purpose of this utility model solves by the following technical programs:
A kind of disk-type winding for dry type water-cooling transformer, comprise stay, it is characterized in that: described stay surrounds round, and on stay, there is around the home inside to walk the copper pipe of cooling water, between the stay that two have copper pipe around the home, be provided with cushion block, two have the stay of copper pipe and cushion block to form one group of disk-type winding around the home.
On described stay, after copper pipe, adopt glass tape around being used as insulating barrier around the home.
The direction around the home of described copper pipe be left around to.
Described copper pipe is that the wall thickness of the color copper pipe of rectangle and copper pipe is 2mm.
The thickness of insulating layer that described glass tape is made is not more than 1/3rd of copper pipe wall thickness.
Disk-type winding is arranged in pairs in transformer outside.
The utility model has the following advantages compared to existing technology:
The utility model by there being around the home inside to walk the copper pipe of cooling water on the stay that surrounds round, and there are around the home the stay of copper pipe and cushion block to form one group of disk-type winding by two, form inside and walk the pitch of the laps structure of the water-electricity integrated of cooling water, external conductive, can accomplish ampere-turn equilibrium, and have that volume is little, activity coefficient is large, the feature of coil good cooling results, belong to low-voltage and high-current coil, therefore be applicable to the occasion of large electric current.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Wherein: 1-copper pipe; 2-stay; 3-cushion block; 4-glass tape.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 1: a kind of disk-type winding for dry type water-cooling transformer, comprise the stay 2 that surrounds round, on stay 2, there is around the home inside to walk the copper pipe 1 of cooling water, between the stay 2 that two have copper pipe 1 around the home, being provided with 3, two of cushion blocks has the stay 2 of copper pipe 1 and cushion block 3 to form one group of disk-type winding around the home; On stay 2, the rear employing glass tape 4 of copper pipe 1, around as insulating barrier, play the effect of the fastening reinforcement of wrapping, and the thickness of insulating layer that glass tape 4 is made is not more than 1/3rd of copper pipe 1 wall thickness simultaneously around the home. Specific to copper pipe 1 itself, copper pipe 1 for the wall thickness of the color copper pipe of rectangle and copper pipe 1 be 2mm, the direction around the home of copper pipe 1 be a left side around to. Above-mentioned disk-type winding is arranged in pairs in transformer outside in addition, belongs to low-voltage and high-current coil.
The utility model by there being around the home inside to walk the copper pipe 1 of cooling water on the stay 2 that surrounds round, and there are around the home the stay 2 of copper pipe 1 and cushion block 3 to form one group of disk-type winding by two, form inside and walk the pitch of the laps structure of the water-electricity integrated of cooling water, external conductive, can accomplish ampere-turn equilibrium, and have that volume is little, activity coefficient is large, the feature of coil good cooling results, belong to low-voltage and high-current coil, therefore be applicable to the occasion of large electric current.
Above embodiment is only explanation technological thought of the present utility model, can not limit protection domain of the present utility model with this, every technological thought according to the utility model proposes, any change of doing on technical scheme basis, within all falling into the utility model protection domain; The technology that the utility model does not relate to all can be realized by prior art.
