Abstract
The invention relates to a manufacturing technology of an on-load adjustable capacity transformer iron yoke insulating part. The technology comprises the steps of processing a circular ring by insulating material, wherein the thickness of the insulating material is sum of the thickness of a pressure plate and the thicknesses of insulating cushion blocks; evenly removing part of the thickness of the processed circular ring by milling, and molding the insulating cushion blocks, wherein the thickness of the removed part of the processed circular ring is the thicknesses of the insulating cushion blocks, and the rest thickness is the thickness of the pressure plate; enabling the insulating cushion blocks to be evenly distributed on the pressure plate, and molding the insulating cushion blocks and the pressure plate into a whole; after that, forming an oil groove in each insulating cushion block, wherein the extending directions of the oil grooves face the center of a circle of the pressure plate; drying the molded integral iron yoke insulating part, dipping the iron yoke insulating part into paint and then drying; enabling the side of the iron yoke insulating part provided with an oil duct to face a coil side and the other side of the iron yoke insulating part to face an iron yoke side. The iron yoke insulating part manufactured by the technology can be prevented from being deformed, the phenomena that a coil has displacement, the electric strength is not guaranteed, the coil is easily burnt out and the like can be prevented in the transportation process, and the safety is improved; furthermore, the oil grooves are formed on the insulating cushion blocks, so that the heat dissipation effect of a transformer is improved.
Description
Technical field
The present invention relates to the technical field that transformer device makes, refer in particular to a kind of manufacture craft of loaded capacity-regulated transformer iron yoke insulation piece.
Background technology
Known in the industry, the size of its capacity of loaded capacity-regulated transformer can change with the change of load, is applicable to the vast rural power grids that seasonal variety is large, because energy-saving effect is remarkable, deeply favors by numerous rural subscribers.But in loaded capacity-regulated transformer, certain structures can not continue to use the structure of common transformer, otherwise can have an accident, and causes damage to user.
Traditional common transformer iron yoke insulation piece is that cross-over block that cardboard that the paper circle made by the cardboard that 3mm is thick and 7mm are thick is made is pasted and formed.Because the lead-out wire of this kind of transformer is more, when welding lead in order to do not destroy to be welded around insulation, generally with around the welding of wet cloth parcel, but iron yoke insulation piece will be contaminated by the moisture on wet cloth and be out of shape, do not press tightly coil, cause and be shifted at transportation coil, do not ensure electrical strength, easily the situations such as coil burnout occur, secondly, because the mechanical strength of product is not high, cause the anti-sudden short circuit scarce capacity of product, when running into external short circuit, coil easily deforms and product is burnt.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of manufacture craft making simple and easy, safe and reliable, practical loaded capacity-regulated transformer iron yoke insulation piece be provided, the iron yoke insulation piece fail safe that this technique is made is high, good heat dissipation effect.
For achieving the above object, technical scheme provided by the present invention is: a kind of manufacture craft of loaded capacity-regulated transformer iron yoke insulation piece, and it comprises the following steps:
Step one, be that the insulating material of thickness of compressive plate and cross-over block summation is processed as annulus with thickness;
Step 2, the annulus processed evenly is milled a part of thickness, make cross-over block shaping, this segment thickness milled is the thickness of cross-over block, and the thickness stayed is the thickness of pressing plate, cross-over block is evenly distributed on pressing plate, and cross-over block and pressing plate are formed in one;
Step 3, on each cross-over block, open oil groove, the bearing of trend of oil groove is towards the center of circle of pressing plate;
Step 4, shaping integral type iron yoke insulation piece is dried, after drying, dipping lacquer is dried again, and vittate one faces coil sides and another side is stand-by towards iron yoke rear flank;
Step 5, integral type iron yoke insulation piece complete.
Making this technique insulating material used is epoxy plate.
The quantity of described cross-over block is plural number.
The groove depth of described oil groove is equal with the height of cross-over block.
The present invention is after have employed such scheme, its great advantage is that the iron yoke insulation piece be made can be avoided occurring distortion, in coil pressing situation, prevent from being shifted at transportation coil, not ensureing the situations such as electrical strength, easily generation coil burnout, improve fail safe, in addition, cross-over block opens oil groove, improve the radiating effect of transformer.
Accompanying drawing explanation
Fig. 1 is process chart of the present invention.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
Shown in accompanying drawing 1, the manufacture craft of the loaded capacity-regulated transformer iron yoke insulation piece described in the present embodiment, it comprises the following steps:
Step one, be that the insulating material of thickness of compressive plate and cross-over block summation is processed as annulus with thickness;
Step 2, the annulus processed evenly is milled a part of thickness, make cross-over block shaping, this segment thickness milled is the thickness of cross-over block, and the thickness stayed is the thickness of pressing plate, cross-over block is evenly distributed on pressing plate, and cross-over block and pressing plate are formed in one;
Step 3, on each cross-over block, open oil groove, the bearing of trend of oil groove is towards the center of circle of pressing plate;
Step 4, shaping integral type iron yoke insulation piece is dried, after drying, dipping lacquer is dried again, and vittate one faces coil sides and another side is stand-by towards iron yoke rear flank;
Step 5, integral type iron yoke insulation piece complete.
The iron yoke insulation piece be made by above-mentioned technique can be avoided occurring distortion, in coil pressing situation, prevent from being shifted at transportation coil, not ensureing the situations such as electrical strength, easily generation coil burnout, improve fail safe, in addition, cross-over block opens oil groove, improves the radiating effect of transformer.
The examples of implementation of the above are only the preferred embodiment of the present invention, not limit practical range of the present invention with this, therefore the change that all shapes according to the present invention, principle are done, all should be encompassed in protection scope of the present invention.
