Abstract
The utility model provides a connection structure of transformer arm -tie and folder, including arm -tie folder and folder down on, the folder is provided with the location axle down, the lower extreme of arm -tie is provided with the locating hole, and lower folder passes locating hole fixed connection with the lower extreme of arm -tie through fixing a position the axle. The utility model is characterized in that, the end left and right sides of the upper end of arm -tie is provided with the journal stirrup respectively, and the journal stirrup of saying is the triangle -shaped form, and the arm -tie upper end of also saying exactly wholly is trapezoidal form. Going up the folder cross section and be anomalous C type, be provided with on the last diaphragm of going up the folder and the diaphragm down and supply last jack that the arm -tie alternates and jack down, the last jack width of saying is greater than arm -tie upper end maximum breadth, and the width of lower jack and the arm -tie of saying be the width matching directly, and the jack inserted on last folder was followed to the arm -tie, with the arm -tie card between the web of last folder. Be provided with the fluting on the arm -tie footpath of saying. The utility model has the advantages of simple and reasonable structure, stability is good, easily processing assembly.
Description
Technical field
The utility model relates to transformer accessory field, particularly relates to the syndeton of a kind of transformer pulling plate and folder.
Background technology
In field transformer, iron core is the basic element of character of transformer, is magnetic circuit and the mounting framework of transformer, and the folder from top to bottom of arm-tie connection transformer.Folder and arm-tie are generally by arranging locating shaft on folder web, offer hole on arm-tie, locating shaft is connected location through hole, the dimension precision requirement of this kind of structure to location fixing hole machining accuracy and upper and lower location hole is high, and arm-tie can not be welded, otherwise assembles difficulty up and down.
Utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art part, provides a kind of rational in infrastructure, is easy to processing, be convenient to the syndeton of transformer pulling plate and the folder assembled.
The syndeton of a kind of transformer pulling plate described in the utility model and folder, include arm-tie, upper clamping piece and lower clamping piece, described lower clamping piece is provided with locating shaft, and the lower end of described arm-tie is provided with location hole, and lower clamping piece is fixedly connected with by locating shaft is passed location hole with the lower end of arm-tie.It is characterized in that, the left and right sides, termination of the upper end of described arm-tie is respectively arranged with journal stirrup, and said journal stirrup is triangle, and namely said arm-tie upper end entirety is in trapezoidal shape.Described upper clamping piece cross section is irregular C type, the upper cross plate of upper clamping piece and lower cross plate are provided with the upper jack and lower jack that intert for arm-tie, said upper jack width is greater than arm-tie upper end Breadth Maximum, the width of lower jack mates with said arm-tie footpath width, arm-tie inserts from jack upper clamping piece, between web arm-tie being stuck in upper clamping piece.Said arm-tie footpath is provided with fluting, and groove width is 4-6mm, is preferably 5mm, and this fluting effectively can reduce eddy current loss unshakable in one's determination.
Further, described arm-tie, upper clamping piece and lower clamping piece scribble insulating barrier.
The beneficial effects of the utility model are: simple and reasonable, good stability, trapezoidal shape structure is arranged in one end of arm-tie, with upper clamping piece clamping, eliminate the operations such as boring, solve folder and arm-tie two ends be all axle fixing coordinate inconvenience problem, solving original structure bad because coordinating, causing transformer discharge problem.
Accompanying drawing explanation
Fig. 1 is the structural representation of the syndeton of a kind of transformer pulling plate described in the utility model and folder, and Fig. 2 is that partial sectional view is looked on a left side for arm-tie described in the utility model and upper clamping piece; 1-upper clamping piece, 2-arm-tie, 3-fluting, 4-lower clamping piece, 5-lower jack 6-upper jack.
Embodiment
Referring now to accompanying drawing 1 and accompanying drawing 2, be described as follows: the syndeton of a kind of transformer pulling plate and folder in conjunction with the embodiments, include arm-tie 2, upper clamping piece 1 and lower clamping piece 4, described lower clamping piece 4 is provided with locating shaft, the lower end of described arm-tie 2 is provided with location hole, and lower clamping piece 4 is fixedly connected with by locating shaft is passed location hole with the lower end of arm-tie 2.It is characterized in that, the left and right sides, termination of the upper end of described arm-tie 2 is respectively arranged with journal stirrup, and said journal stirrup is triangle, and namely said arm-tie upper end entirety is in trapezoidal shape.Described upper clamping piece 1 cross section is irregular C type, the upper cross plate of upper clamping piece 1 and lower cross plate are provided with the upper jack 6 and lower jack 5 that intert for arm-tie, said upper jack 6 width is greater than arm-tie upper end Breadth Maximum, the width of lower jack 5 mates with said arm-tie 2 footpath width, arm-tie 2 inserts from jack upper clamping piece 1, between web arm-tie 2 being stuck in upper clamping piece 1.Said arm-tie 2 footpath is provided with fluting 3, and 3 width of slotting are 4-6mm, are preferably 5mm, and this fluting 3 effectively can reduce eddy current loss unshakable in one's determination.
Further, described arm-tie 2, upper clamping piece 1 and lower clamping piece 4 scribble insulating barrier.
The beneficial effects of the utility model are: simple and reasonable, good stability, trapezoidal shape structure is arranged in one end of arm-tie, with upper clamping piece clamping, eliminate the operations such as boring, solve folder and arm-tie two ends be all axle fixing coordinate inconvenience problem, solving original structure bad because coordinating, causing transformer discharge problem.
