Abstract
The utility model discloses a three-phase transformer body insulation structure which comprises four iron yoke baffle plates (1) arranged at a top and a bottom of a coil (4), eight cushion blocks (2) made of laminated wood and four press plates (3) made of the laminated wood which are arranged at the top and the bottom of the coil (4). The cushion blocks (2) and the press plates (3) tightly press the coil (4). The three-phase transformer body insulation structure has the advantages of low cost, good heat dissipation and good insulation.
Description
Technical field:
The utility model relates to a kind of transformer technology field, specifically is a kind of three-phase transformer device body insulation structure.
Background technology:
Present three-phase transformer device body insulation structure mainly comprise six core insulations being located at coil top and bottom, four iron yoke dividing plates, eight by the wooden cushion block that becomes of electric insulation with four by the wooden pressing plate that becomes of electric insulation; This cushion block and pressing plate are the parts of transformer body wooden pieces, have the effect that compresses coil, auxiliary heat dissipation cooling, insulation.There is following shortcoming in the transformer body of above prior art: 1, owing to be provided with core insulation, cost height, poor radiation between coil and cushion block, the briquetting; 2, eight by the cushion block of the wooden one-tenth of electric insulation with four its moisture is big relatively by the wooden pressing plate bad mechanical strength that becomes of electric insulation, insulating properties is relatively poor.
The utility model content
The technical problem that the utility model will solve is, provides that a kind of cost is low, the three-phase transformer device body insulation structure of good heat dissipation, good insulating.
The technical scheme of the utility model is; A kind of three-phase transformer device body insulation structure with following structure is provided; Comprise four the iron yoke dividing plate that is located at coil top and bottom; It also comprise eight of being located at coil top and bottom by the wooden cushion block that becomes of lamination with four by the wooden pressing plate that becomes of lamination, said cushion block and pressing plate are pressed on the coil.
Said cushion block is pressed on the coil through drawing screw rod to be connected folder from top to bottom with pressing plate.
After adopting said structure; The utility model compared with prior art has the following advantages: since it also comprise eight of being located at coil top and bottom by the wooden cushion block that becomes of lamination with four by the wooden pressing plate that becomes of lamination, said cushion block and pressing plate are pressed on the coil; On the structure; Can remove core insulation paper circle, reduce cost, increase heat dispersion; The general electric insulation timber of its material replacement of cushion block and pressing plate has improved mechanical strength, and coil more is prone to compress, and has reduced burr, has fallen material; Its moisture is few, and insulation property are strong, good looking appearance; Its medium electric constant and transformer oil are approaching, help the even distribution in magnetic field.
Description of drawings
Accompanying drawing 1 is the sketch map of the three-phase transformer device body insulating part of the utility model.
Accompanying drawing 2 is A-A generalized sections of Fig. 1.
Shown in the figure: 1, iron yoke dividing plate, 2, cushion block, 3, pressing plate, 4, coil.
Embodiment
Be described further below in conjunction with the three-phase transformer device body insulation structure of accompanying drawing the utility model.
Like Fig. 1, shown in Figure 2; The three-phase transformer device body insulation structure of the utility model; Comprise four the iron yoke dividing plate 1 that is located at coil 4 tops and bottom; It also comprise eight of being located at coil 4 tops and bottom by the wooden cushion block 2 that becomes of lamination with four by the wooden pressing plate 3 that becomes of lamination, said cushion block 2 is pressed on the coil 4 with pressing plate 3.The top that is to say three-phase transformer device body be provided with two iron yoke dividing plates 1, four by the cushion block 2 of the wooden one-tenth of lamination with two by the wooden pressing plate 3 that becomes of lamination.
Said cushion block 2 is pressed on the coil 4 through drawing screw rod to be connected folder from top to bottom with pressing plate 3.
Claims (2)
1. three-phase transformer device body insulation structure; Comprise four the iron yoke dividing plate (1) that is located at coil (4) top and bottom; It is characterized in that: it also comprise eight of being located at coil (4) top and bottom by the wooden cushion block (2) that becomes of lamination with four by the wooden pressing plate (3) that becomes of lamination, said cushion block (2) and pressing plate (3) are pressed on the coil (4).
2. three-phase transformer device body insulation structure according to claim 1 is characterized in that: said cushion block (2) is pressed on the coil (4) through drawing screw rod to be connected folder from top to bottom with pressing plate (3).
