Abstract
The utility model discloses a large power transformer iron core pulling plate which comprises a pulling plate, a reinforcing plate connected with the lower end of the pulling plate, and a pulling threaded rod connected with the upper end of the pulling plate. The pulling plate is composed of at least two S690D alloy steel plates which are horizontally placed in sequence and at equal intervals. The large power transformer iron core pulling plate utilizes a plurality of the S690D alloy steel plates which are arranged at equal intervals to replace traditional monoblock pulling plates which are provided with through grooves, thereby achieving functional integration of tight claming and lifting, simplifying the structure, consciously reducing added losses of the pulling plate while guaranteeing mechanical strength, and meeting requirements of users to the utmost extent.
Description
Technical field
The utility model relates to field transformer, particularly a kind of large-scale power transformer iron core arm-tie.
Background technology
Large-scale power transformer generally adopts pulling plate structure at present; Traditional arm-tie, for guaranteeing enough mechanical strengths and reduce as far as possible perpendicular to arm-tie surface leakage magnetic flux and cause additional eddy current loss, the steel plate that has several grooves by a monoblock is usually processed; Will be in the manufacturing process through milling groove, weldering two ends stiffener, auger shell pit and hanging axis hole, weldering hanging axis; Processing technology is complicated, along with the continuous increase of power transformer capacity, and the improving constantly of electric pressure; Transformer core is also constantly developing towards hugeization, and traditional pulling plate structure can not satisfy the requirement of optimum performance.
The utility model content
It is little that the technical problem that the utility model will solve provides a kind of additional eddy current loss, can guarantee the iron core chuck strength effective large-scale power transformer iron core arm-tie of handling iron core simultaneously.
For achieving the above object, the technical scheme of the utility model is following:
A kind of large-scale power transformer iron core arm-tie, it comprise stiffener that arm-tie and arm-tie lower ends connect and be connected with the arm-tie upper end draw screw rod; Said arm-tie is made up of at least 2 equally spaced successively horizontal positioned of S690D steel alloy steel plate.
Preferably, the distance between said per two S690D steel alloy steel plates is 3mm.
Preferably, the said quantity of screw rod of drawing is identical with S690D steel alloy steel plate quantity.
Preferably, said stiffener is welded on the arm-tie lower end.
Through technique scheme, the beneficial effect of the utility model is:
The utility model is with being divided into the traditional monoblock arm-tie that has groove of arm-tie replacement that a plurality of equally spaced steel plates are formed; Realized the unification of clamping hoisting function; Designs simplification; The also conscious arm-tie supplementary load loss that reduced satisfy user's requirement to greatest extent when having guaranteed mechanical strength.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model end view.
The numeral corresponding component title represented among the figure with letter:
10, arm-tie 11, steel plate 20, stiffener 30, draw screw rod
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Said referring to Fig. 1 and Fig. 2, a kind of large-scale power transformer iron core of the utility model arm-tie comprise the stiffener 20 that arm-tie 10 and arm-tie 10 lower ends connect and be connected with arm-tie 10 upper ends draw screw rod 30; Said arm-tie 10 is made up of at least 2 S690D steel alloy steel plates 11 equally spaced successively horizontal positioned.
Distance between per two the S690D steel alloy steel plates 11 of the utility model is 3mm, draws the quantity of screw rod 30 identical with S690D steel alloy steel plate 11 quantity.
The utility model stiffener 20 is welded on arm-tie 10 lower ends, and it also will be with surface rubbing after welding.
The utility model adopts the equidistant arm-tie 10 of distinguish and draws screw rod 30 structures, reduces the eddy current loss that vertical leakage flux produces at arm-tie when guaranteeing the iron core chuck strength, and makes the handling of iron core easily convenient.
After the utility model is considered leakage flux and iron core folder mechanical strength, arm-tie 10 is designed to two lobes or the low magnetic arm-tie of the division more than two lobes, draws screw rod 30 to be used for the large-scale power transformer lifting as the hanging beam strong point; Reduce the eddy current loss that vertical leakage flux produces at arm-tie when guaranteeing the iron core chuck strength, and make the handling of iron core easily convenient.
As shown in Figure 1; Arm-tie 2 adopts pintongs steel plates 11, and it is welded together that the utility model bottom stiffener 20 and pintongs steel plate 11 and top four draw screw rod 30 to join, and bottom stiffener 20 is reserved perforates and cooperated fastening with iron core folder web (not marking among the figure); Middle part pintongs steel plate 11 spacings are filled with insulating pad; Four at top draws screw rod 30 to cooperate fastening back as the hanging beam strong point with last fagging (not marking among the figure), behind the folder integral locking, lifts by crane with hanging beam.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
