Abstract
The utility model discloses an upper positioning device for a flat-top oil tank of a transformer, which comprises a cover plate, a flange disc, an insulating cushion block, an insulating cushion plate and an insulating paper board. A positioning hole is formed on a tank cover of the oil tank; a positioning device matched with the positioning hole is arranged on an upper supporting plate of an iron core; the flange disc is fixed at the positioning hole of the tank cover of the oil tank; the positioning device is arranged in the positioning hole of the tank cover of the oil tank in a penetrating way; the positioning device and the tank cover of the oil tank are tightly supported and fixed by the insulating cushion plate and the insulting paper board; the cover plate is hermetically and fixedly arranged at the upper end of the flange disc; and the insulating cushion block is placed in the positioning device, the upper supporting plate of the iron core and the cover plate are tightly supported and fixed, and an insulating gap is reserved between the positioning device and the cover plate. The upper positioning device for the flat-top oil tank of the transformer is firm in fixation, low in cost, good in insulation effect and long in service life.
Description
Technical field
The utility model relates to a kind of last positioner of transformer flat-head type fuel tank.
Background technology
In the power transformer industry; We often run into the transformer requirement is barrel type tank; And the case lid of barrel type tank is generally flat-head type, so, the following fixed form of the general employing in location, top of existing this transformer body: on the flat-head type case lid, add rising seat of weldering with certain altitude; The positioner that leans out on the last fagging unshakable in one's determination stretches in the seat that raises; And leave clearance for insulation with the seat that raises, and being fixedly clamped between the positioner on the last fagging and the fuel tank case lid location hole, cover plate is fixed in the rising through being fixed on ring flange on the seat that raises.The steadiness of this fixed form is poor, and fuel tank and transformer body insulation effect are poor, and the height that raise seat and ring flange are added up is high, and the positioner on the last fagging is long, wastes steel, the cost height, the positioner on the last fagging is yielding, useful life weak point.
The utility model content
The purpose of the utility model is exactly to solve the problems referred to above that exist in the prior art, and a kind of transformer body fixation that makes the flat-head type fuel tank is provided, and cost is low, and insulation effect is good, the last positioner of the transformer flat-head type fuel tank of long service life,
For addressing the above problem, the technical solution of the utility model is: a kind of last positioner of transformer flat-head type fuel tank, and it comprises cover plate, ring flange, cross-over block, insulating pad and insulating board; On the fuel tank case lid location hole is arranged, the positioner that is complementary with location hole is arranged on the fagging on the iron core; Ring flange is fixed on the location hole place of fuel tank case lid, and positioner is through in the location hole of fuel tank case lid, fixes with insulating pad and insulating board stretching between positioner and the fuel tank case lid; Ring flange upper end sealing and fixing has cover plate; Cross-over block places in the positioner, and fagging on the iron core and cover plate stretching are fixed, and leaves the insulation slit between positioner and the cover plate.
Seal by sealing gasket between above-mentioned described ring flange and the cover plate.
Be lined with another insulating board between fagging and the cross-over block on the above-mentioned described iron core.Insulating board is in order to the height of adjustment cross-over block.
The utility model has increased the cross-over block stretching between fagging on the iron core and cover plate fixes, and it is fixing more firm, and the insulation effect of fuel tank and transformer body is better; And saved the seat that raises; Reduced the length of positioner, saved steel, cost is low; Positioner is not yielding, has prolonged useful life.Use insulating board between fagging and the cross-over block on the iron core, stretching is regulated convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, it comprises cover plate 6, ring flange 7, cross-over block 3, insulating pad 5 and insulating board 4 present embodiment.On the fuel tank case lid 1 location hole is arranged, the positioner 9 that is complementary with location hole is arranged on the fagging 2 on the iron core.Ring flange 7 is welded on the location hole place of fuel tank case lid 1, and positioner 9 is through in the location hole of fuel tank case lid, fixes with insulating pad 5 and insulating board 4 stretchings between positioner 9 and the fuel tank case lid 1.There is cover plate 6 ring flange 7 upper ends by sealing gasket 8 sealing and fixing.Cross-over block 5 places in the positioner 9 with another insulating board 10, and fagging on the iron core 2 and cover plate 6 stretchings are fixed, and leaves the insulation slit between positioner 9 and the cover plate 6.
Claims (3)
1. the last positioner of a transformer flat-head type fuel tank, it comprises cover plate, ring flange, insulating pad and insulating board, on the fuel tank case lid location hole is arranged, and the positioner that is complementary with location hole is arranged on the fagging on the iron core; It is characterized in that: it also comprises cross-over block; Ring flange is fixed on the location hole place of fuel tank case lid, and positioner is through in the location hole of fuel tank case lid, fixes with insulating pad and insulating board stretching between positioner and the fuel tank case lid; Ring flange upper end sealing and fixing has cover plate; Cross-over block places in the positioner, and fagging on the iron core and cover plate stretching are fixed, and leaves the insulation slit between positioner and the cover plate.
2. the last positioner of transformer flat-head type fuel tank according to claim 1 is characterized in that: sealed by sealing gasket between described ring flange and the cover plate.
