Description
Technical field
The utility model is related to transformer technology field, more particularly to a kind of EFD shape transformers safety skeleton.
Background technology
At present, the safety regulation of high frequency transformer has two kinds：
(1) creep age distance for the high frequency transformer of basic insulation requirement is more than 3mm；
(2) the creep age distance requirement for the transformer of reinforced insulation requirement is more than 6mm.
It is generally that lead is hung on the stitch of skeleton in current production during the lead of line bag, bone
In the stitch of frame and winding slot around the distance of line can reach the 3mm of basic insulation requirement, but do not reach reinforced insulation
The requirement of 6mm.
For the product of reinforced insulation requirement, current solution technology is that lead makes fly line form from fly line groove extraction,
Wire length may be designed to more than 6mm, and this technology solves the requirement apart from inadequate 6mm.
But, this technology brings the decline of difficulty and production efficiency to production, because with the fly line total length of money product
There is regulation with upper tin length, so product is when production will wear FTL pipe, coiling employee each product length on request
Carry out coiling, action and time this adds increased measurement also improve the technical requirements in production operation；The tin when person on lead
Work will control the length of tin, also increase here a time of the employee when length is controlled and to the technical requirements of employee very
It is high.Operation will also increase the operation that a length standard cuts afterwards.
So generally, for making the product when institute that fly line form produces insulating requirements with existing skeleton lead
It is multiplex more than 9 seconds that time hangs over every 1 product on stitch than equivalent material and under requiring.
Accordingly, it is desirable to provide a kind of EFD shape transformers safety skeleton is solving above-mentioned technical problem.
Utility model content
The utility model mainly solving the technical problems that provide a kind of EFD shape transformers safety skeleton, by by coiling
Groove side stitch is placed plate and is widened so that the stitch of side place in plate and winding slot around the distance of line can to reach reinforcement exhausted
The distance of edge 6mm, production can reach safety requirement after improving, and product is safer, also time-consuming in production, improve
Production efficiency, also reduces operating technology during production, and the stitch of winding slot opposite side place in plate and winding slot around
The distance of line continues to reach the distance of reinforced insulation 3mm, therefore, EFD shape transformers safety skeleton of the present utility model can
For the power transformer product of 3mm safety requirement, it is also possible to for the power transformer product of 6mm safety requirement.
In order to solve the above technical problems, the technical scheme that the utility model is used is to provide a kind of EFD shape transformers
Safety skeleton, including：Rectangle winding slot 1, first baffle 2, second baffle 3, first baffle 2 and second baffle 3 are separately positioned on
On one end of rectangle winding slot 1, the Basolateral of first baffle 2 is provided with first stitch of the bottom with stitch 111 and places plate
4, the Basolateral of second baffle 3 is provided with second stitch of the bottom with stitch 111 and places plate 5, and the first stitch places the edge of plate 4
Length on the length direction of rectangle winding slot 1 is 3.5mm, and the second stitch is placed on length direction of the plate 5 along rectangle winding slot 1
Length be 7.8mm.First baffle 2 and second baffle 3 it is highly equal, be provided with first baffle 2 and the top surface of second baffle 3
Fly line goes out line groove 112.
It is preferred that, it is in the same plane with the top surface of rectangle winding slot 1 that fly line goes out the top surface of line groove 112.
The beneficial effects of the utility model are：A kind of EFD shape transformers safety skeleton that the utility model is provided, not only may be used
To reach the safety requirement of basic insulation 3mm distances, and reach the safety requirement of reinforced insulation 6mm distances.
Brief description of the drawings
Fig. 1 is a kind of structural representation of EFD shape transformers safety skeleton of the present utility model.
Specific embodiment
The technical solution of the utility model is described in detail with reference to diagram.
It is shown in Figure 1, the EFD shape transformer safety skeletons of the present embodiment, including rectangle winding slot 1, first baffle
2nd, second baffle 3, first baffle 2 and second baffle 3 are separately positioned on one end of rectangle winding slot 1, the bottom of first baffle 2
Outside is provided with first stitch of the bottom with stitch 111 and places plate 4, and the Basolateral of second baffle 3 is provided with bottom and carries
Second stitch of stitch 111 places plate 5, and first baffle 2 is 3.5mm, second along the length on the length direction of rectangle winding slot 1
Baffle plate 3 is 7.8mm along the length on the length direction of rectangle winding slot 1.First baffle 2 and second baffle 3 it is highly equal,
Fly line is provided with one baffle plate 2 and the top surface of second baffle 3 go out line groove 112.
, when in use, be wound on line on circular winding slot 1 first by the EFD shape transformer safety skeletons of the present embodiment, treats line
Enough number of turns are bypassed, the end of fly line is placed into plate bottom from stitch is wound on the stitch 111 of the second stitch placement plate 5.Due to
Second stitch places extension of the plate 5 to fly line creep age distance, ensure that fly line creep age distance reach the safety of more than 6mm will
Ask, thus need not again carry out fly line measurement of length and shearing such that it is able to significantly improve the manufacture efficiency of transformer.Separately
Outward, get over and then be welded on the stitch 111 that the first stitch is placed on plate 4 if fly line places the bottom of plate 4 from the first stitch, can
Ensure the safety demand of basic insulation 3mm above fly line creep age distances, therefore, the EFD shape transformer safety skeletons of the present embodiment
Disclosure satisfy that the safety requirement of more than 3mm and two kinds of creep age distances of more than 6mm fly lines.
In a preferred embodiment of the present utility model, fly line goes out the top surface of the top surface of line groove 112 and rectangle winding slot 1
It is in the same plane.
The beneficial effects of the utility model are：A kind of EFD shape transformers safety skeleton that the utility model is provided, not only may be used
To reach the safety requirement of basic insulation 3mm distances, and reach the safety requirement of reinforced insulation 6mm distances.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure made using the utility model specification and accompanying drawing content, or directly or indirectly it is used in other related technologies
Field, is similarly included in scope of patent protection of the present utility model.
