Abstract

The utility model discloses a kind of supporting structure of transformer box cover, it is characterized in that, iron core upper beam including connection iron core low pressure upper clamping piece, iron core high pressure upper clamping piece, iron core upper beam is equipped with electrical laminated wood, the outer rim of electrical laminated wood length direction is equipped with baffle, the outer rim of width is equipped with angle steel shield frame, and electrical laminated wood is fitted close with case lid.Wooden unit is close to the case lid of transformer, has not only played support but also has played insulating effect.This supporting structure iron core upper beam is to use steel plate, and wooden unit is to use electrical laminated wood, its intensity height do not allow it is yielding, effectively prevent transformer box cover sink deformation.The utility model can realize the independent support of case lid, effectively prevent transformer box cover and sink to deforming, reduce the welding capacity that case lid strengthens iron, reduce manufacture cost.

Description

A kind of supporting structure of transformer box cover

Technical field

A kind of supporting structure of transformer box cover is the utility model is related to, belongs to electrical equipment technical field.

Background technology

For large oil immersed power transformer, traditional structure for preventing case lid sinking deformation is on case lid Weld many places and strengthen iron.The shortcomings that structure, is：1st, as the capacity increase of transformer, its overall volume also constantly increase Greatly, transformer tank is caused to cover to weld many places and strengthen iron and prevent from deforming, it is more that it takes the space of case lid, increase processing work When and welding job amount；2nd, the appearance and size of case lid is more big more to be difficult to guard box lid indeformable, once sink above will for case lid Product water-deposited soil, phenomena such as growing grass, it seriously affects the good appearance degree of transformer and the use of user.

The content of the invention

To be solved in the utility model is the problem of existing transformer box cover is easily deformed.

To solve the above-mentioned problems, the technical solution of the utility model there is provided a kind of support knot of transformer box cover Structure, it is characterised in that the iron core upper beam including connection iron core low pressure upper clamping piece, iron core high pressure upper clamping piece, iron core upper beam are equipped with Electrical laminated wood, the outer rim of electrical laminated wood length direction are equipped with baffle, and the outer rim of width is equipped with angle steel shield frame, electrician's layer Pressed wood is fitted close with case lid.

Preferably, the baffle is yi word pattern；The angle steel shield frame is L-type.

Wooden unit is close to the case lid of transformer, has not only played support but also has played insulating effect.This supporting structure iron core upper beam is to use Steel plate, wooden unit are to use electrical laminated wood, its intensity height do not allow it is yielding, effectively prevent transformer box cover sink deformation.

The utility model can realize the independent support of case lid, effectively prevent transformer box cover and sink to deforming, reduce Case lid strengthens the welding capacity of iron, reduces manufacture cost.

Brief description of the drawings

Fig. 1 is a kind of front view of the supporting structure of transformer box cover provided by the utility model；

Fig. 2 is the top view of iron core upper beam.

Embodiment

To become apparent the utility model, hereby with preferred embodiment, and attached drawing is coordinated to be described in detail below.

Embodiment

As shown in Figure 1, 2, it is a kind of supporting structure of transformer box cover provided by the utility model, it includes connecting iron core The iron core upper beam 3 of low pressure upper clamping piece 1, iron core high pressure upper clamping piece 2, two are welded in the upper plane of iron core upper beam 3 in the width direction The angle steel shield frame 7 of block L-type structure, welds two block baffles 6, the space that both are surrounded and electrical laminated wood 4 in the longitudinal direction It is engaged, is put into electrical laminated wood 4, be close to the case lid 5 of transformer, not only plays support but also play insulating effect.Iron core upper beam 3 is adopted It is made of steel plate, the intensity of electrical laminated wood 4 is high, it is not easy to deform, effectively prevent transformer box cover and sink to deforming.
