Abstract
A support cover relates to the technical field of transformer low-voltage windings and comprises a bow-shaped cover body with the central angle more than 180 degrees; the circumferential edge of at least one end face of the bow-shaped cover body is chamfered; the distance from the plane of the bow-shaped cover body to the central angle is greater than one half of the radius of the end face of the bow-shaped cover body. Firstly, a plurality of axial through holes are arranged on the cover body; part of the cover body is cut off along the direction vertical to the end face of the cover body; the central angle of the rest part of the bow-shaped cover body is greater than 180 degrees; then the cover body edge is chamfered into large fillet, so that the cover body can easily enter into a low-voltage coil to tighten up the low-voltage coil so as to ensure the internal diameter size of the low-voltage coil to enable the low-voltage coil not to be deformed due to external forces. After part of the cover body is cut off, a plane is formed on the support cover; the length of the plane and the distance from the plane to the central angle can be decided by the lead arrangement of low-voltage coils with different capacity to ensure the performance level of the transformer products.
Description
Technical field
The utility model relates to the technical field of transformer low voltage coiling.
Background technology
Be wrapped in low-voltage coil on the transformer after coiling finishes, there is not relevant position to be maintained fixed mutually between the adjacent row, so when the demoulding, low-voltage coil is easy deformation under the effect of coiling tension force by it, can't ensure the size of low voltage winding in transformers, have influence on the overall performance of transformer.
The utility model content
The utility model purpose provides a kind of supporting cover.This supporting cover guarantees that low-voltage coil is indeformable under the inside/outside diameter size that requires after the low-voltage coil coiling is intact, ensured the performance level of power transformer product.
The utility model comprises the arc lids of central angle greater than 180 degree, and at least in the circumferential edges chamfering of an end face of arc lid, the plane of described arc lid is to half greater than arc lid end face radius of the distance in the center of circle.
The utility model is arranged several axially extending bores earlier on lid, and the direction of prolonging vertical and lid end face cuts the part lid, the remainder central angle is greater than the arc lid of 180 degree, and the lid edge carried out big fillet, mainly be that it can be thrown into smoothly in the low-voltage coil, the stretching low-voltage coil, thus the low-voltage coil internal diameter size guaranteed, guarantee that it is not out of shape because of external force.Leave the plane after cutting the part lid on supporting cover, the length on plane and plane are arranged decision to the distance of central angle by the lead-in wire of the low-voltage coil of different capabilities, have ensured the performance level of power transformer product.
The utility model is provided with axially extending bore on arc lid.Be convenient to the fixing of arc lid, help realizing the indeformable effect of low-voltage coil inside/outside diameter size.
Axially extending bore of the present utility model is distributed on the arc lid.Improved the stability of arc lid, stressed even, be not easy to deform.
The above-mentioned axially extending bore of the utility model is half of arc lid end face radius to the distance in the arc lid center of circle.Improved supporting cover stability in use.
The diameter of each axially extending bore of the utility model is 16mm～20mm.Rational in infrastructure, strengthened the result of use of product.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
As shown in the figure, central angle is greater than the arc lids 1 of 180 degree, and at least one end face 5 of described arc lid 1 or 6 circumferential edges are provided with chamfering, and the plane of described arc lid 13 is to half greater than arc lid 1 end face radius of the distance in the center of circle 4.
On the arc lid 1 axially extending bore 2 is set.Axially extending bore 2 is distributed on the arc lid 1.Axially extending bore 2 is half of arc lid 1 end face radius to the distance in arc lid 1 center of circle 4.The diameter of each axially extending bore 2 is 16mm～20mm.
As shown in Figure 2, be on two end faces 5 and 6 of arc lid 1, all to be provided with chamfering.
After the low-voltage coil coiling finishes, after the demoulding, use supporting cover stretching low-voltage coil internal diameter at the scene on request.To guarantee the position of low pressure during with supporting cover stretching low-voltage coil internal diameter, and then carry out dry dipping lacquer on request, after all process steps is finished, again supporting cover is broken away from low-voltage coil, it is indeformable that it can be guaranteed under the size that requires, guarantee the inside/outside diameter size of low-voltage coil, ensured the performance level of power transformer product.
