Abstract
The utility model relates to the technical field of the manufacturing of a transformer, in particular to a core side-limb tightening device. The core side-limb tightening device comprises lamination wood boards (1), lamination wood supports (2) and nylon insulating bolts (3), wherein the lamination board is the semi-circle board; a plurality of lamination wood boards (1) are buckled with a plurality of lamination wood supports (2) to form a semi-circle cylindrical framework; and the lamination boards are fixedly connected with the lamination wood supports (2) by the nylon insulating bolts (3). The tightening device is arranged at the two sides of an oval-shaped core side limb to form the cylindrical shape respectively. In the utility model, with the adoption of the framework type structure, the oil flow at the filling position is unobstructed, thereby being favorable for heat dissipation of the core side limb; and the framework type structure can save large amount of materials. The tightening device has the characteristics that the structure is simple and reasonable, the materials are saved, the processing and manufacturing can be convenient, etc.
Description
Technical field
The utility model relates to a kind of technical field of transformer manufacturing, specifically a kind of stretching device of iron core side pole.
Background technology
In the Monophase electric power transformer, when placing the pressure regulation winding on the single-phase other post, it is circular needing the oval yoke stretching of other post, to make things convenient for the suit of pressure regulation winding.At present, traditional stretching mode is with the laminated wood filled type of stack layer by layer.This kind structural laminated wood consumption is big, and filling position oil stream is not smooth, influences the iron core side pole heat radiation, and requires quality of fit higher to laminated wood, otherwise is difficult to cooperate with iron core side pole docile.
Summary of the invention
The purpose of this utility model provides a kind of simple and reasonable for structure, saves material, is convenient to the iron core side pole stretching device of processing and manufacturing.
The technical solution adopted in the utility model is: a kind of iron core side pole stretching device, comprise laminated wood, also comprise lamination timbering and nylon insulated bolt, described laminated wood is a semicircular plate, a plurality of laminated woods and a plurality of lamination timbering interlock and form the framework of semicircle cylinder shape, and laminated sheet is fixedlyed connected with the lamination timbering by the nylon insulated bolt.
Distributing on the described lamination timbering is provided with groove, and laminated sheet inserts the semicircle cylinder shape framework of the interior formation of groove on the lamination timbering.
Also can distribute on the periphery of laminated wood is provided with groove, forms semicircle cylinder shape framework in the groove of lamination timbering insert layer pressing plank.
The utility model utilizes the lamination timbering several laminated woods to be pegged graft into the framework of semicircle cylinder shape, then the framework of semicircle cylinder shape is separately positioned on the both sides of oval-shaped iron core side pole, form cylindric, with just having carried out the suit of pressure regulation winding after the colligation of high-strength polyester band, the filled type that originally only uses laminated wood to pile up is layer by layer saved lot of materials; The utility model is convenient to make processing, simplifies technology, increases work efficiency, and is beneficial to the operation of next procedure; The utility model adopts tower structure to make the circulation of filling position oil smooth, helps the heat radiation of iron core side pole.

Fig. 1 is a structural representation of the present utility model
Fig. 2 is the structural representation after the utility model and the iron core side pole assembling
Embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, mainly comprise laminated wood 1, lamination timbering 2 and nylon insulated bolt 3, described laminated wood 1 is a semicircular plate, a plurality of laminated woods 1 interlock with a plurality of lamination timberings 2 and form the framework of semicircle cylinder shape, present embodiment is provided with groove for distributing on lamination timbering 2, a plurality of laminated sheets are inserted into respectively in the groove on a plurality of lamination timberings 2, thereby form semicircle cylinder shape framework.Laminated sheet is fixedly connected to form one by nylon insulated bolt 3 and lamination timbering 2 then.Because the utility model adopts tower structure, make the circulation of filling position oil smooth, help the heat radiation of iron core side pole 4; And the more original filled type structure of piling up layer by layer of tower structure is saved lot of materials; The utility model is convenient to make processing, simplifies technology, increases work efficiency, and is beneficial to the operation of next procedure.The utility model can also distribute on the periphery of laminated wood 1 and be provided with groove, will form semicircle cylinder shape framework in the groove of lamination timbering 2 insert layer pressing planks 1.
During use, the stretching device of pegging graft into semicircle cylinder shape framework is separately positioned on the both sides of oval iron core side pole 4, with high-strength polyester band 5 the stretching device is fixedlyed connected with iron core side pole 4 then, thereby form cylindric, see Fig. 2, so just can carry out the suit of pressure regulation winding.
This shows, the utlity model has simple and reasonable for structurely, save material, be convenient to the characteristics such as processing and manufacturing.
