Abstract
The utility model discloses a flat-top clock cover type power transformer case cover deformation-resisting device which is arranged between an upper beam (2) and a case cover (1) of a power transformer. The flat-top clock cover type power transformer case cover deformation-resisting device comprises supporting iron (3), a supporting piece (4) and a connecting piece (5), the lower portion of the supporting piece (4) is fixed on the supporting iron (3) through the connecting piece (5), the supporting iron (3) is welded to the upper beam (2), the upper end of the supporting piece (4) is in seamless supporting contact with the middle portion of the case cover (1), and the upper beam (2) is fixed between clamping pieces (6). The flat-top clock cover type power transformer case cover deformation-resisting device is simple in structure, reinforcing ribs on the upper portion of the case cover are cancelled, welding deformation of the case cover is reduced, production cost of a transformer oil tank is reduced, negative-pressure-resisting capability of the top of the oil tank is improved, clearance area of the top of the transformer is increased, the upper space of the case cover is not occupied, the arrangement of the top components is not affected, and the insulation performance between the clamping pieces and the oil tank is ensured.
Description
Technical field
The utility model relates to a kind of flat-top bell glass type electric transformer, particularly a kind of flat-top bell glass type electric transformer case lid Anti-deformation device.
Background technology
In bell glass type electric transformer manufacturing process, all require oil tank of transformer can bear the negative pressure that vacuum degree is 133Pa, and can bear the required vacuum degree of vacuum oil, and do not produce expendable distortion.The fuel tank tank wall is all by the brush line of whole steel plate rolling some, and intensity can meet the demands.And the flat roof type top of oil-tank is the weakest link, often distortion, all at top of oil-tank, therefore need be welded at top of oil-tank the reinforcement intensive treatment of vertical and horizontal.There is following drawback:
1. increase steel plate materials, improved cost, increased top pressure-bearing burden simultaneously.
Need the welding many places, easily cause the case lid welding deformation.
Due to the existence of reinforcement, affect the layout of case lid top assembly.
Due to the obstruct of reinforcement, cause the easy ponding in top.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of flat-top bell glass type electric transformer case lid Anti-deformation device is provided, make transformer oil tank structure simple, reduce production costs, improve the anti-negative pressure ability of flat roof type top of oil-tank, reduce the case lid welding deformation, be convenient to the layout of top assembly and be difficult for ponding, guaranteeing the insulation property between folder and fuel tank.
The purpose of this utility model is achieved through the following technical solutions: flat-top bell glass type electric transformer case lid Anti-deformation device, it is arranged between the case lid and upper beam of power transformer, it comprises Zhi Tie, connector and strutting piece, the lower end of strutting piece is fixed on Zhi Tie, the upper end of strutting piece contacts with the seamless support of top cover, the welding of Zhi Tieyu upper beam, upper beam is fixed between folder.
The upper end of strutting piece described in the utility model contacts with the case lid seamless support in middle part.
Strutting piece described in the utility model is lamination wood part.
Connector described in the utility model comprises nuts and bolt.
The beneficial effects of the utility model are: simple in structure, reduced the oil tank of transformer production cost; Improved the anti-negative pressure ability of flat-top top of oil-tank, reduced the top cover welding deformation, improved transformer top headroom area, vacant case upper part of the cover space, do not affect the layout of top assembly and be difficult for ponding, guaranteed the insulation property between folder and fuel tank.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation front view;
Fig. 2 is the utility model structural representation left view;
In figure, the 1-case lid, the 2-upper beam, 3-props up iron, 4-strutting piece, 5-connector, 6-folder.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection range of the present utility model is not limited to the following stated.
As Fig. 1, shown in Fig. 2, flat-top bell glass type electric transformer case lid Anti-deformation device, it is arranged between the case lid 1 and upper beam 2 of power transformer, and it comprises iron 3, connector 5 and a strutting piece 4, and the lower end of strutting piece 4 is fixing by connector 5 with an iron 3, the upper end of strutting piece 4 contacts with the case lid 1 seamless support in middle part, prop up iron 3 and upper beam 2 welding, upper beam 2 is fixed between folder 6, and wherein said connector 5 can adopt nuts and bolt structure, pin feature, bolt structure etc.
Strutting piece 4 described in the utility model is lamination wood part, and lamination wood part is longer useful life, has guaranteed the permanent support effect of strutting piece 4 and the insulation property between folder and fuel tank.
