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 is made, 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 variation of load, is applicable to the vast rural power grids that seasonal variety is large, remarkable because of energy-saving effect, favored by numerous rural subscribers.But in loaded capacity-regulated transformer, certain structures can not be continued to use the structure of common transformer, otherwise can have an accident, and to user, causes damage.
Traditional common transformer iron yoke insulation piece is that cross-over block that the paper circle made by a thick cardboard of 3mm and the thick cardboard of 7mm are made is pasted and formed.Because the lead-out wire of this kind of transformer is more, when welding lead in order not destroy insulation around to be welded, generally will be with around the welding of wet cloth parcel, but iron yoke insulation piece will be contaminated and be out of shape by the moisture on wet cloth, do not press tightly coil, cause at transportation coil and be shifted, do not guarantee electrical strength, easily the situations such as coil burnout occur, secondly, because the mechanical strength of product is not high, the anti-sudden short circuit scarce capacity that causes product, while 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 of making simple and easy, safe and reliable, practical loaded capacity-regulated transformer iron yoke insulation piece is provided, iron yoke insulation piece that this technique is made is safe, 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 1, with the insulating material that thickness is thickness of compressive plate and cross-over block summation, be processed as annulus;
Step 2, the annulus of having processed is evenly milled to a part of thickness, make cross-over block moulding, the thickness that this segment thickness milling is cross-over block, the thickness that the thickness staying is 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, the integral type iron yoke insulation piece of moulding 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 equates with the height of cross-over block.
The present invention is after having adopted such scheme, its great advantage is that the iron yoke insulation piece being made can avoid occurring distortion, in coil pressing situation, prevent from being shifted, not guaranteeing electrical strength, easily the situations such as coil burnout occur at transportation coil, improved fail safe, in addition, on cross-over block, open oil groove, improved 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 1, with the insulating material that thickness is thickness of compressive plate and cross-over block summation, be processed as annulus;
Step 2, the annulus of having processed is evenly milled to a part of thickness, make cross-over block moulding, the thickness that this segment thickness milling is cross-over block, the thickness that the thickness staying is 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, the integral type iron yoke insulation piece of moulding 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 being made by above-mentioned technique can avoid occurring distortion, in coil pressing situation, prevent from being shifted, not guaranteeing electrical strength, easily the situations such as coil burnout occur at transportation coil, improved fail safe, in addition, on cross-over block, open oil groove, improved the radiating effect of transformer.
The examples of implementation of the above are only the present invention's preferred embodiment, not with this, limit practical range of the present invention, therefore the variation that all shapes according to the present invention, principle are done all should be encompassed in protection scope of the present invention.
