Abstract
The utility model relates to a bending type magnetic shielding tool for machining a transformer oil tank, and belongs to the technical field of transformer manufacturing. The technical field is that the bending type magnetic shielding tool comprises a magnetic shielding base seat (1) and a cushion block (2). The cushion block is arranged on the magnetic shielding base seat. The cushion block is a wedge-shaped cushion block. The wedge-shaped angle (3) of the wedge-shaped cushion block is the same as the bending angle of the transformer oil tank. The bending type magnetic shielding tool for machining the transformer oil tank has the advantages that a bending mechanism is removed, the cushion block replaces the bending mechanism, when magnetic shielding is achieved in an adhering and bending mode, the cushion block is placed on the magnetic shielding base seat, the angle of the cushion block is fixed, adjusting is of no need, the bending angle of the transformer oil tank can be well guaranteed, and working efficiency and quality are improved.
Description
Technical field
The utility model relates to a kind of processing oil tank of transformer bendable magnetic screen frock, belongs to technical field of transformer manufacturing.
Background technology
Iron core in the transformer is mounting framework and the magnetic circuit of transformer, the supplementary load loss that produce in leakage field metal clip normally unshakable in one's determination and the oil tank wall under the transformer load state.In order effectively to reduce its loss, generally all adopt the method that magnetic screen is installed that the leakage field that imports above-mentioned position into is shielded.So-called magnetic screen, the barricade that adopts exactly the electrical steel sheet manufacturing to form, be installed in it on folder or be embedded on the inwall of fuel tank, because silicon steel sheet has extremely strong permeance, therefore can provide a preferably flux path for leakage field, thereby the effect that core clamping or the oil tank wall of its installation position played magnetic leakage shielding is to reach the purpose that reduces eddy current loss in these positions.Magnetic screen is by the use location classification, be divided into folder magnetic screen and fuel tank magnetic screen, and the fuel tank magnetic screen is divided into panel magnetic shielding and bendable magnetic screen, when making the magnetic screen of bendable fuel tank, the magnetic screen of dogleg section needs the bending mechanism of adjusting tool could realize bending function, but the bad adjusting of dogleg section angle is difficult for measuring, and uses that efficient is low, quality is low.
The utility model content
The purpose of this utility model provides a kind of processing oil tank of transformer bendable magnetic screen frock, and is simple and easy, efficient, and can replace the bending function of former bending magnetic screen frock, solves the problems referred to above that background technology exists.
The technical solution of the utility model is: a kind of processing oil tank of transformer bendable magnetic screen frock, comprise magnetic screen base and cushion block, and cushion block is arranged on the magnetic screen base, and cushion block is correcting wedge.
Described correcting wedge wedge angle is consistent with the oil tank of transformer bending angle, substitutes original frock.
The magnetic screen intermediate demand is pressed the certain angle bending, it designs for the structure of applicable transformer oil chamber interior wall, but because there is bending angle in this type of magnetic screen at the middle part, therefore key point is how can guarantee well its bending angle after shielding is finished, it can be matched with inner wall of oil tank well in installation process.
Good effect of the present utility model: by the cancellation bending mechanism, cushion block is replaced bending mechanism, when bonding bending magnetic screen, cushion block is placed on the magnetic screen base, and the angle of cushion block is fixed, and need not regulate, can guarantee well its bending angle, increase work efficiency and quality.
Description of drawings
Fig. 1 is the structure chart of the utility model embodiment;
Among the figure: magnetic screen base 1, cushion block 2, wedge angle 3.
Embodiment
Below in conjunction with accompanying drawing, by embodiment the utility model is described further.
A kind of processing oil tank of transformer bendable magnetic screen frock comprises magnetic screen base 1 and cushion block 2, and cushion block is arranged on the magnetic screen base, and cushion block is correcting wedge.Described correcting wedge wedge angle 3 is consistent with the oil tank of transformer bending angle, substitutes original frock.
By the cancellation bending mechanism, cushion block is replaced bending mechanism, when bonding bending magnetic screen, cushion block is placed on the magnetic screen base, the angle of cushion block is fixed, and need not regulate, and can guarantee well its bending angle, increases work efficiency and quality.
Claims (2)
1. process oil tank of transformer bendable magnetic screen frock for one kind, it is characterized in that: comprise magnetic screen base (1) and cushion block (2), cushion block is arranged on the magnetic screen base, and cushion block is correcting wedge.
2. described a kind of processing oil tank of transformer bendable magnetic screen frock according to claim 1 is characterized in that described correcting wedge wedge angle (3) is consistent with the oil tank of transformer bending angle.
