Abstract

The utility model discloses a kind of New Low Voltage paper tinsel winder body structure, to comprise inside iron core, coil, low pressure copper bar and folder outside copper bar, low pressure, mounting coil is on iron core, folder is located at outside unshakable in one's determination, inside low pressure, copper bar adopts in line, it draws between iron core and folder from coil, and low pressure copper outside comes outside folder and draws from coil.The utility model is mainly applicable to the machine body structure that low-voltage coil is paper tinsel coiling, has compact conformation, easy to make, safe and reliable feature.

Description

New Low Voltage paper tinsel winder body structure

Technical field

The utility model relates to a kind of low voltage foil winding coil machine body structure.

Background technology

At present, transformer producer makes low-voltage coil when being the machine body structure of paper tinsel coiling, the structure adopted be all inner side copper bar by the copper bar outlet method of drawing outside folder, and outlet copper bar bending size is larger, mainly there is following problem:

1, traditional low voltage foil winding coil machine body structure, inside low pressure, copper bar is drawn by outside folder, and the bending degree of outside copper bar increases, and after lead-in wire, device body width dimensions increases, thus cause fuel tank size to increase, cause and produce the waste of material and the raising of production cost;

2, traditional low voltage foil winding coil machine body structure, when inner side copper bar is drawn by folder outside, device body is by making the decline by a small margin of device body after vacuumize, folder declines can to copper bar inside lower compression, thus cause interior outer copper line spacing not ensure, usual needs add the laggard row colligation of fagging between interior outer copper line, thus add cost of labor, reduce production efficiency.Vibrations when transformer runs can cause the loosening of fagging, come off, and run there is potential safety hazard to transformer.

Summary of the invention

For solving the problems referred to above that existing low voltage foil winding coil machine body structure exists, the utility model provides a kind of New Low Voltage paper tinsel winder body structure, and its technical scheme adopted is:

To comprise inside iron core, coil, low pressure copper bar and folder outside copper bar, low pressure, mounting coil is on iron core, and folder is located at outside unshakable in one's determination, and inside low pressure, copper bar adopts in line, it draws between iron core and folder from coil, and low pressure copper outside comes outside folder and draws from coil.

This kind of machine body structure effectively reduces device body width dimensions, and inside low pressure, copper bar avoids inner bending, makes simple, reduces copper bar production process, shorten fabrication cycle, reduce copper bar use amount simultaneously.Outside low pressure, copper bar bending size reduces, and saves material, reduces production cost; Transformer body after vacuum drying, device body fall avoid folder to inner side copper bar to lower compression, ensure that the safe distance of interior outside copper bar, after solving the drying of traditional machine body structure device body, cause the potential safety hazard that the spacing deficiency of interior outside copper bar exists because folder falls.

The utility model is mainly applicable to the machine body structure of oil-filled transformer low voltage foil winding coil, effectively reduces volume of transformer, save production cost, improve product quality by the machine body structure after optimizing.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figure 1, be sleeved on by coil 2 on unshakable in one's determination 1, copper bar 3 inside low pressure, folder 5 is located at the outside of unshakable in one's determination 1, and inside low pressure, copper bar 3 adopts in line, and draw from coil 2 between unshakable in one's determination 1 and folder 5, outside low pressure, copper bar 4 is drawn outside folder 5.Realize blessing to copper bar inside low pressure 3 top by fastening folder 5, inside low pressure, attached insulation is wrapped up on copper bar 3 top simultaneously, ensure its insulation property.

Claims
