Abstract
The utility model relates to a locating part for protecting an electrostatic ring at the end part of a high-voltage oil-immersed type transformer coil, which is an L-shaped insulating part manufactured by machining a cushion block processed by an insulating paper board and a laminated paper board. By adopting the technical scheme, the locating part can play effective locating role for the electrostatic ring at the end part of the coil and strengthen the protection on the insulation of the electrostatic ring, thus ensuring that the electrostatic ring has enough electrical strength to the ground, and further guaranteeing the long-term safety running of the transformer.
Description
Technical field
The utility model relates to a kind of transformer coil electrostatic ring keeper, the electrostatic ring keeper of particularly a kind of effectively set winding end electrostatic ring.
Background technology
Along with the progress of transformer manufacturing technology and insulation technology, the coil head end is generally all placed electrostatic ring in the existing high voltage transformer insulating Design, and the surge voltage that is adjacent all line segments with improvement distributes, and makes the winding overhang electric field even.This just makes that the insulation of electrostatic ring itself is very important, if the electrostatic ring damage in insulation, electrostatic ring will be lost should effect, becomes new point of discharge.
The utility model content
The technical problems to be solved in the utility model is: when solution high voltage transformer end winding electrostatic ring press-fits, because the bounce-back of body coil, make the inside and outside stay of coil not play effective positioning action to electrostatic ring, cause the electrostatic ring skew, so that when press-fiting, inside and outside stay is poked the problem of electrostatic ring insulation.
The technical scheme that its technical problem that solves the utility model adopts is: first cushion block that have a L type insulating board, is positioned at a side on the insulating board is with vertical mutually with first cushion block and be positioned at second cushion block on the insulating board.
On the basis of technique scheme, further comprise the other technologies scheme:
First and second cushion block is that laminated paper board processes.
A kind of transformer that contains electrostatic ring with keeper, it comprises electrostatic ring, outer stay, line cake, the interior stay of several spaces, cardboard cylinder, wherein electrostatic ring uses the insulating board of keeper near cardboard cylinder.
The electrostatic ring keeper is positioned at the inboard of line cake.
The electrostatic ring keeper is positioned at the middle place of two adjacent stays.
The inboard of electrostatic ring is enclosed within first cushion block outside.
The beneficial effects of the utility model are: use electrostatic ring protection L type keeper in transformer coil of the present utility model end in high voltage transformer; can solve when press-fiting; because the bounce-back of body coil; make the inside and outside stay of coil not play effective positioning action to electrostatic ring; cause the electrostatic ring skew; so that when press-fiting, inside and outside stay is poked the problem of electrostatic ring insulation, thereby guarantee that product can the long-term safety operation.The utility model manufacturing cost is extremely low, manufacturing, easy construction.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is the left view of Fig. 1.
Fig. 3 is that the master that the utility model is applied to transformer looks user mode figure;
Among the figure: 1 cardboard, 2. first cushion block, 3. second cushion block, 4. electrostatic ring, 5. outer stay, 6. line cake, 7. in stay, 8. cardboard cylinder.
Embodiment
As depicted in figs. 1 and 2, transformer coil electrostatic ring keeper of the present utility model has the L type
Insulating board 1, be positioned at a side on the insulating board 1 first cushion block 2 with vertical mutually with first cushion block 2 and be positioned at second cushion block 3 on the insulating board 1, first cushion block 2 and second cushion block 3 are fixed on the cardboard 1 by bonding mode, also can be fixed on the cardboard by other modes.For ease of producing, can not adopt L type cardboard earlier yet, directly adopt 1mm 100/00 flat board, earlier cardboard is cut into the cardboard 1 that requires size, to first cushion block 2 and second cushion block 3 that laminated paper board is processed on request be fixed on the cardboard 1 by bonding mode then, be bent into the L type at last, though so manufacture method different, but purpose is identical with the purpose of this utility model, also within one of ordinary skill in the art understanding scope.
As shown in Figure 3 and Figure 4, it is for adopting the embodiment of above-mentioned electrostatic ring with the transformer of keeper, and this transformer comprises interior stay 7, the cardboard cylinder 8 of electrostatic ring 4, outer stay 5, line cake 6, several circumferential spaces at least.Electrostatic ring keeper of the present utility model generally when coiling, is placed on the inboard between coil head end line cake 6 3-4 cakes, and the position is the middle place of two adjacent interior stays 7, and cardboard 1 is generally along the circumferential direction evenly being placed 4～6 near cardboard cylinder 8.When electrostatic ring 4 was placed, its inboard must be enclosed within cushion block 2 outsides, can't ride on the cushion block 2.
In sum, adopt the technical solution of the utility model, can solve when press-fiting, because the bounce-back of body coil, make the inside and outside stay of coil not play effective positioning action, cause electrostatic ring skew, so that when press-fiting electrostatic ring, inside and outside stay is poked the problem of electrostatic ring insulation, thereby guarantees that product can the long-term safety operation.The utility model manufacturing cost is extremely low, manufacturing, easy construction.
Though the utility model with preferred embodiment openly as above; but it is not in order to limit the utility model; any person skilled in the art; in not breaking away from spirit and scope of the present utility model; all can do various changes and modification, therefore protection range of the present utility model should be with being as the criterion that claims were defined.
