Abstract
The invention relates to a production method for a small oil duct vehicle-mounted transformer. Self-adhesion transposed wires insulated by being covered with paper or multiple thick insulation combined wires serve as transformer coils, and the axial dimension of oil ducts ranges from 2.5 mm to 3.5 mm. The production method is characterized in that the transformer coils are wounded into a plurality of transformer wire cakes respectively, and a plurality of cushion blocks are arranged between the transformer wire cakes; a technological insertion plate of the corresponding thickness is inserted in the middle of the part between every two adjacent cushion blocks, the inserted technological insertion plates are vertically aligned, then the transformer coils are put into a drying tank to be dried at the constant pressure, and the technological insertion plates are taken out after drying is finished and before press fitting is carried out. The production method has the advantages that the press fitting technology of the transformer coils is improved, the height of the transmission coils is reduced, so that the height and the size of the transformer are reduced, the uniformity and the technological order of the size of the oil ducts between the coil cakes are ensured, and the method is easy and convenient to implement and practical.
Description
Technical field
The present invention relates to mobile transformer and manufacture field, particularly a kind of production method of little oil duct mobile transformer.
Background technology
How mobile transformer finite volume, increase transformer capacity, reduces volume of transformer, becomes and pursue direction.
Summary of the invention
Object of the present invention is just to provide a kind of production method of little oil duct mobile transformer, reduces volume of transformer.
To achieve these goals, the technical solution used in the present invention is: a kind of production method of little oil duct mobile transformer, transformer coil adopts to cover paper insulated tack transposed conductor or heavy insulation many composite conductors, the axial dimension of oil duct is between 2.5 ~ 3.5mm, it is characterized in that: transformer coil is turned to respectively multiple transformer wire cake, wherein, multiple cushion block is placed with between described multiple transformer wire cake; Insert the technique plate of respective thickness in adjacent two grades of cushion block centre positions, the technique plate consistency from top to bottom of insertion, then, puts into drying chamber and carries out Constant pressure drying, take out technique plate after drying completes before press-fiting by transformer coil.
The present invention's beneficial effect is compared to existing technology: improve transformer coil press mounting technique, reduce the height of transformer coil, thus reduce transformer height and volume, entering drying chamber at transformer coil carries out in the process of Constant pressure drying, can coil insulation be effectively avoided to subside, ensure that oil duct size uniform between line cake and technique regular, method is simple and practical.

Embodiment
General plotting of the present invention is, by multiple transformer coil is carried out coiling respectively, generate multiple transformer wire cake, and insert plate in the adjacent pod of described multiple cushion block, thus avoid coil insulation to subside, ensure that oil duct size between line cake and technique equal.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Fig. 1 is the production method flow chart of the little oil duct mobile transformer of the embodiment of the present invention, and step S101, carries out coiling respectively by multiple transformer coil, generates multiple transformer wire cake, wherein, is placed with multiple cushion block between described multiple transformer wire cake.Step S102, insertion process plate in adjacent pod.
Fig. 2 is the front view of the production method of the little oil duct mobile transformer of the embodiment of the present invention; Fig. 3 is the vertical view of accompanying drawing 2; Fig. 4 is the reference diagram of the production method of the little oil duct mobile transformer of the embodiment of the present invention; First transformer coil is turned to respectively multiple transformer wire cake, wherein, between described multiple transformer wire cake 1 and line cake 22, be placed with multiple cushion block 3; Insert the technique plate 4 of respective thickness in adjacent two grades of cushion block centre positions, technique plate 4 consistency from top to bottom of insertion, then, puts into drying chamber and carries out Constant pressure drying, take out technique plate 4 after drying completes before press-fiting by transformer coil.Transformer coil adopts and covers paper insulated tack transposed conductor or heavy insulation many composite conductors, and the axial dimension of oil duct is between 2.5 ~ 3.5mm, and both cushion block height was 2.5 ~ 3.5mm.
This method improves transformer coil press mounting technique, reduce the height of transformer coil, thus reduce transformer height and volume, entering drying chamber at transformer coil carries out in the process of Constant pressure drying, can coil insulation be effectively avoided to subside, ensure that oil duct size uniform between line cake and technique regular, method is simple and practical.
Above-described embodiment; object of the present invention, technical scheme and beneficial effect are further described; the foregoing is only the specific embodiment of the present invention; the protection range be not intended to limit the present invention; within the spirit and principles in the present invention all; any amendment of making, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
