Abstract
The utility model belongs to a transformer assembly and relates to a large-current hoist seat structure of a transformer, which comprises an upper flange, a lower flange and a low-voltage hoist seat cylinder wall arranged between the upper flange and the lower flange. A plurality of out-leading lines penetrate through the upper flange through a plurality of low-voltage sleeves, a plurality of leads corresponding to the out-leading lines penetrate through the lower flange, the low-voltage hoist seat cylinder wall is provided with a hand hole for connecting the leads and the out-leading line, the hand hole is provided with a hand hole cover plate and the low-voltage hoist seat cylinder wall is further provided with a hanging hole. A traditional large-current lead exerted on one hoist seat is divided into a plurality of small-current out-leading lines, and field intensity of current exerted on each lead is reduced so that a leakage magnetic field generated around the hoist seat is reduced and a synthesized leakage magnetic field of all hoist seats is reduced. Accordingly, eddy current loss generated in a steel plate is reduced, local overheat of a box cover and the hoist seats is effectively controlled, and reliability in operation and service life of the transformer are improved.
Description
Technical field
The utility model belongs to transformer device, relates to the big electric current rising of a kind of transformer holder structure.
Background technology
Along with the continuous increase of electrical network transmission capacity, transformer separate unit capacity also increases gradually, and the transformer output current also increases simultaneously.The common employing of traditional transformer outlet is every draws through the seat that raises with a big electric current sleeve pipe mutually; Single-phase big electric current produces bigger stray field around can causing the seat that raises; Thereby in the fuel tank outer cover of steel plate because of vortex induction; Cause fuel tank, rising seat the local overheating phenomenon to occur easily, influence transformer temperature rise and life-span.
Summary of the invention
The utility model provides the big electric current rising of a kind of transformer easy to operate, that stray field is little holder structure in order to remedy the deficiency of prior art.
The utility model is realized through following technical scheme:
The big electric current rising of the transformer of the utility model holder structure; Its special character is: comprise upper flange, lower flange and be installed in upper flange and lower flange between the low pressure seat barrel that raises; Run through through several low-tension bushings on the upper flange that some outlets being installed, run through on the lower flange that the some bar lead-in wires corresponding with outlet being installed, low pressure raises and is useful on the hand hole that is operatively connected lead-in wire and outlet on the seat barrel; The hand hole cover plate is installed on the hand hole, hangs nose in addition on the low pressure rising seat barrel.
The big electric current rising of the transformer of the utility model holder structure, low-tension bushing are 2-4, and outlet is corresponding each other 2-4 bar with lead-in wire.
The beneficial effect of the utility model is; Rising of former cause great current lead wire of bearing is diverted to a plurality of little electric current outlets, the electric current field intensity that the seat that raises carries is reduced, thereby reduce to raise a stray field that produces on every side; And the synthetic stray field of each seat that raises also reduces; Thereby the eddy current loss that produces in the reduction steel plate has effectively been controlled case lid, a rising seat local overheating, improves transformer reliability of operation and life-span; This product is mainly used in 35～1000kV level high-power transformer.
Description of drawings
Fig. 1 looks sketch map for the master of the utility model, and Fig. 2 is a schematic top plan view.
Among the figure, 1 low-tension bushing, 2 rising seat upper flanges, 3 a low pressure rising seat barrel, 4 hand hole cover plates, 5 hang nose, 6 a rising lower flange, 7 lead-in wires.
Embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.
The big electric current rising of the transformer of the utility model holder structure; Comprise upper flange 2, lower flange 6 and be installed in upper flange and lower flange between the low pressure seat barrel 3 that raises; Run through through several low-tension bushings 1 on the upper flange that some outlets being installed, run through on the lower flange that the some bar lead-in wires 7 corresponding with outlet being installed, low pressure raises and is useful on the hand hole that is operatively connected lead-in wire and outlet on the seat barrel; Hand hole cover plate 4 is installed on the hand hole, hangs nose 5 in addition on the low pressure rising seat barrel.Low-tension bushing 1 is 2-4, and outlet is corresponding each other 2-4 bar, preferred 4 with lead-in wire.
This transformer low voltage rising seat is a critical component that supports the transformer low voltage sleeve pipe, is rectangle; For high-power transformer, its low-pressure side electric current is bigger, adopts single big electric current sleeve pipe through the seat outlet that raises, and the lead-in wire of single sleeve pipe and winding coupling is just thicker, is unfavorable for connecting.The present invention changes every mutually single sleeve pipe into 2～4 sleeve pipes through the seat outlet structure that raises through the seat outlet that raises; Change the sleeve pipe of 2～4 little electric currents into by the sleeve pipe of single big electric current in the power transformer enclosure like this, thereby reduced the diameter of lead-in wire, be beneficial to the connection operation of lead-in wire and sleeve pipe; Be divided into four little current feeds to great current lead wire; Be beneficial to operation, field intensity becomes the stack of four little electric current field intensity by big electric current field intensity, has reduced local field strength.
