Abstract
The utility model discloses an amorphous alloy transformer coil which is provided with a high voltage coil with rectangle structure and a low voltage coil with rectangle structure, the high voltage coil is nested on the low voltage coil and a main hollow channel is arranged between the two coils, the amorphous alloy transformer coil is characterized in that: the main hollow channel is composed of N pieces of insulation paper wound in overlap manner, at least two paper board strips are respectively inserted between two pieces of insulation paper in short axis direction of the main hollow channel, and the gap of the two paper board strips form an oil channel. The amorphous alloy transformer coil has the beneficial effects that: under the same safety insulation effect, the thickness of the main hollow channel is reduced, the outer diameter of the main hollow channel is reduced, the construction and distribution structure of the oil channel are improved at the same time, and the material consumption of the outer layer high voltage coil is reduced.
Description
Technical field
The utility model belongs to the transformer technology field, is specifically related to a kind of amorphous alloy transformer coil.
Background technology
Existing amorphous alloy transformer all is provided with high-tension coil and low-voltage coil all is a rectangular configuration, high-tension coil and low-voltage coil are sleeved on the iron core, and high-tension coil is sleeved on the low-voltage coil, between high-tension coil and low-voltage coil, main empty path is set, and between the winding of high-tension coil, main empty path is set also.Main empty path increases the creepage distance between the coil, realizes between high-tension coil and the low-voltage coil and the insulation between high pressure and the high pressure.For reducing the working temperature of transformer, need on main empty path, arrange oil duct.
It mainly is to twine a circle watt rib paper in main empty path that traditional oil duct is provided with, and realizes the layout of oil duct by watt rib, and the layout of watt rib paper, has also increased the thickness of main empty path, and it is wide to make main empty path reach 9mm.
Traditional structural disadvantages is: main empty path thickness is wide, and oil duct is arranged too much, has increased the external diameter of main empty path, has also just increased the material consumption of outmost turns high-tension coil.
The utility model content
The purpose of this utility model is to propose a kind of amorphous alloy transformer coil that can reduce the external diameter of main empty path, under identical safe insulation effect, reduces the material consumption of high-tension coil.
For achieving the above object, the utility model provides a kind of amorphous alloy transformer coil, be provided with the high-tension coil of rectangular configuration and the low-voltage coil of rectangular configuration, described high-tension coil is sleeved on the low-voltage coil, the two structure is concentric, be provided with main empty path between high-tension coil and the low-voltage coil, its key is: described main empty path is opened the overlapping winding of insulating paper by N and is constituted, be inserted with at least two paperboard strip respectively between the insulating paper on two short-axis directions of this main empty path, the gap between this paperboard strip forms oil duct.
Described main empty path is made of 24～28 overlapping windings of insulating paper.
Also be provided with three or four layers of crimped paper between the insulating paper of described main empty path, described coil is stretched out at the two ends of this crimped paper.
Utilize the insulation effect of insulating paper and crimped paper, can increase creepage distance between high-tension coil and the low-voltage coil, can dwindle the thickness of main empty path, make main empty path thickness narrow down to 3mm, can significantly reduce the consumption of materials of outer ring high-tension coil.
Between the insulating paper on two short-axis directions of described main empty path, be inserted with four paperboard strip respectively.
Can be on short- axis direction 3,5 of plug-in mountings or more paperboard strip, with the support effect of reinforced paperboard bar, guarantee the unimpeded effect of oil duct simultaneously to oil duct.
Four paperboard strip only are inserted on the short-axis direction of transformer coil, and the main empty path of transformer coil long axis direction is to be made of insulating paper and the overlapping winding of crimped paper entirely, therefore, has reduced the coiling amplitude of high-tension coil, reach the purpose of saving material.
Remarkable result of the present utility model is: the amorphous alloy transformer coil that can reduce the main empty path external diameter is provided, under identical safe insulation effect, reduced the thickness of main empty path, reduced the external diameter of main empty path, improve the formation and the distributed architecture of oil duct simultaneously, reduced the material consumption of outer high-tension coil.
