Abstract
A mould for forming the isolating air channel of the windings in transformer by vacuum casting is made up of the arc section with sealed cavity through using conic internal arc wall plate, reverse-conic external arc wall plate and upper and lower ring plates to construct a hollow cylinder, temporarily installing the oblique side plates between said internal and external wall plates to form several hollow formworks, cutting and taking the internal and external arc wall plates and upper and lower ring plates of each hollow formwork, and riveting said ring plates and left and right oblique side plates onto said arc wall plate to form conic hollow formwork.
Description
Technical field
The present invention relates to a kind of isolation gas channel formation mould for vacuum casting transformer coil and preparation technology thereof.
Background technology
At present, the air flue plate that uses can be divided into two classes both at home and abroad, and a class is the solid air flue plate of metal; Another kind of is nonmetal solid air flue plate.The solid air flue plate of metal is owing to be solid, thus heavy especially, use very inconvenient; Nonmetal solid air flue plate is selected the manufacturing of import high-quality POM raw material for use, and material price is expensive especially, and production cost is very high.
Summary of the invention
The objective of the invention is to provide a kind of isolation gas channel formation mould for vacuum casting transformer coil and preparation technology thereof, and this preparation technology is not only reasonable in design, low cost of manufacture, and also its mould uses light.
Isolation gas channel formation mould for vacuum casting transformer coil of the present invention, its structural feature is: be made of the circular-arc section bar with closed cavity.
The preparation technology of isolation gas channel formation mould for vacuum casting transformer coil of the present invention, carry out according to the following steps, with circular arc wallboard in conical, on turbination external arc wallboard reaches, lower annular plate is formed open circles tubular body, on described, the spacing of lower annular plate equals the height of hollow template, and interior, the interim oblique side plate that hollow template is installed between the external arc wallboard, on open circles tubular body, to form several hollow templates around circumference, then cut each hollow template in, on the external arc wallboard reaches, lower annular plate, to go up at last, a lower annular plate and a left side, in right oblique side plate is riveted on, on the external arc wallboard, make the taper hollow template.
The power transformer product that adopts mould of the present invention to produce, not only not oil-filled, compact conformation, volume are little, in light weight, and have characteristics such as good insulation preformance, difficult combustion, dustproof, protection against the tide, also have simultaneously highly polished, smooth surface is smooth, material hardness is moderate, advantages such as plasticity is good, can go deep into load center, be specially adapted to the power transmission and distribution in skyscraper, residential block, airport, station, harbour, industrial and mining enterprises and tunnel that fire safety is had higher requirements, simultaneously the complete transformer station of also very suitable composition.

The specific embodiment
Isolation gas channel formation mould for vacuum casting transformer coil of the present invention is characterized in that: be made of the circular-arc section bar with closed cavity.
Described circular-arc section bar is by inside and outside circular arc wallboard 1 and 2, be set at inside and outside circular arc wallboard perimembranous upper and lower annular slab 3 and 4 and left and right oblique side plate 5 and 6 connect and compose, its longitudinal profile is back taper (as Fig. 3), wide on the described circular-arc hollow profile, following narrow (as Fig. 1).
The preparation technology of isolation gas channel formation mould for vacuum casting transformer coil of the present invention, carry out according to the following steps, with circular arc wallboard 1 in conical, turbination external arc wallboard 2 reaches, lower annular plate 3 and 4 is formed open circles tubular body, on described, the spacing of lower annular plate equals the height of hollow template, and interior, the interim oblique side plate 5 and 6 that hollow template is installed between the external arc wallboard, on open circles tubular body, to form several hollow templates around circumference, then cut each hollow template in, on the external arc wallboard reaches, lower annular plate, to go up at last, a lower annular plate and a left side, in right oblique side plate is riveted on, on the external arc wallboard, make the taper hollow template.
The power transformer product that adopts mould of the present invention to produce, not only in light weight, can alleviate working strength of workers, and also easy for operation; The tensile strength of product, bending strength, fatigue performance height; Product uses continuously repeatedly, and no concave-convex, warpage, metaboly can not rupture yet, and is therefore safe and reliable, long working life.
