Abstract
An amorphous alloy coil pressing structure comprises a plurality of high-and-low-voltage coils arranged side by side and an upper clamping plate located at the axial tops of the high-and-low-voltage coils. The amorphous alloy coil pressing structure is characterized in that multiple sets of pressing assemblies are fixedly arranged on the two sides of the upper clamping plate. According to the particularity of an amorphous alloy transformer body structure, after the pressing assemblies are arranged on the two sides of the upper clamping plate, the high-and-low-voltage coils are locked in the axial direction, the axial pre-tightening force of the high-and-low-voltage coils is effectively increased, therefore, even if short circuit occurs in a transformer of the structure, the high-and-low-voltage coils of the transformer cannot generate axial deformation, and the amorphous alloy coil pressing structure has the advantages of being stable in performance and long in service life.
Description
[technical field]
The utility model relates to a kind of amorphous alloy coil compressing structure.
[technical background]
In recent years, amorphous alloy transformer is developed rapidly with its outstanding low no-load loss characteristic, favored by consumer.But due to the particularity of amorphous alloy transformer body structure, when transformer is short-circuited, axial deformation can occur high-voltage coil and low-voltage coil, has both affected transformer performance, reduction of service life, the safe operation of returning electric power facility has left hidden danger.
[summary of the invention]
For overcoming the problems referred to above, the utility model aims to provide a kind of amorphous alloy coil compressing structure, the transformer that utilizes this compressing structure to make has particularly preferred anti-short-circuit capacity, even if run into short-circuited coil, also axial deformation phenomenon can not occur, and has advantages of stable performance, long service life.
For achieving the above object, the utility model has adopted following technical proposals, this amorphous alloy coil compressing structure, comprise some the high-voltage coil and low-voltage coils that are arranged side by side, and the train wheel bridge that is positioned at these axial tops of high-voltage coil and low-voltage coil, it is characterized in that: in the both sides of described train wheel bridge, be fixed with many covers and hold down assembly.
As preferably, during described many covers hold down assembly, every cover holds down assembly and consists of supporting bracket, locking nut, screw and laminated wooden block, described supporting bracket is fixedly connected on train wheel bridge side, an end face of a face of described laminated wooden block and described high-voltage coil and low-voltage coil offsets, and described locking nut and screw make this laminated wooden block form pretightning force to described high-voltage coil and low-voltage coil.
Beneficial effect: compared with prior art, the utility model is for the particularity of amorphous alloy transformer body structure, after train wheel bridge both sides arrange many covers and hold down assembly, high-voltage coil and low-voltage coil is axially locked, effectively increase the axial pre tightening force of high-voltage coil and low-voltage coil, therefore, even if the transformer of this structure runs into short circuit, also can not there is the phenomenon of axial deformation in its high-voltage coil and low-voltage coil, have advantages of stable performance, long service life.
Below in conjunction with accompanying drawing, by an embodiment, the utility model is described in further detail.

Fig. 3 is the structure for amplifying schematic diagram of A portion in Fig. 2.
In figure: train wheel bridge 1, high-voltage coil and low-voltage coil 2, supporting bracket 3, screw 4, train wheel bridge side 5, locking nut 6, laminated wooden block 7, lower plate 8.
[embodiment]
Referring to Fig. 1, and in conjunction with Fig. 2, Fig. 3.This amorphous alloy coil compressing structure, comprises some the high-voltage coil and low-voltage coils that are arranged side by side 2, and the train wheel bridge 1 that is positioned at these high-voltage coil and low-voltage coil 2 axial tops.In the both sides of described train wheel bridge 1, be fixed with many covers and hold down assembly, its quantity is determined by the concrete quantity of high-voltage coil and low-voltage coil 2, and the present embodiment has three high-voltage coil and low-voltage coils 2, therefore, 8 covers is set and holds down assembly, and 4 covers are established respectively in both sides.
As preferably, every cover holds down assembly and consists of supporting bracket 3, locking nut 6, screw 4 and laminated wooden block 7, supporting bracket 3 is fixedly connected on train wheel bridge side 5, the upper surface of the bottom surface of described laminated wooden block 7 and described high-voltage coil and low-voltage coil 2 offsets, backspin screw 4 is under the cooperation of locking nut 6, laminated wooden block 7 is pressed on to the upper surface of high-voltage coil and low-voltage coil 2, forms pretightning force.Because the bottom face of all high-voltage coil and low-voltage coils 2 is supported by lower plate 8, therefore, hold down assembly behind location, high-voltage coil and low-voltage coil 2 is not just prone to axial deformation phenomenon.
Above-described embodiment is only for explaining of the present utility model opening one's minds, and any simple deformation structure of having done under the present embodiment inspires, all should be considered as falling into protection range of the present utility model.
