Abstract
The utility model relates to a three-phase thin insulation epoxy-casting dry transformer, aiming to solve the problem that the traditional oil immersed transformer is not suitable the areas of high pollution, salt spray, dust and the like. The transformer comprises a low-voltage winding (1), a high-voltage winding (2) and an iron core (4). A transformer body is formed by assembling the insulation (3) of the transformer body and a leading wire (5). The low-voltage winding (1) is wound by a copper coil. The high-voltage winding (2) adopts a four-section winding structure, a glassfiber chopped felt is filled between the sections and the end surfaces, and two flexible grid clothes are used between the layers. The iron core (4) adopts a five-stage stepping folding sheet type. The utility model has the advantages of attractive structure, stable property, low noise, low local emission, energy saving, convenient maintenance, dust prevention, fog prevention, fire protection, no pollution, and reutilization after service life terminating.

Along with the expansion of urban infrastructure construction scale and being on the increase of skyscraper, and people are to the attention of product environmental protection, the attention of product appearance, especially in areas such as some high pollutions, salt fog, dusts, oil-filled transformer is not suitable for. so just be badly in need of a kind of have simple and beautiful structure, easy to maintenance, fire prevention, fire-retardant, dustproof novel transformer.
Summary of the invention:
The utility model has been unsuitable for the technical problem that use in areas such as some high pollutions, salt fog, dust in order to solve present oil-filled transformer, a kind of have simple and beautiful structure, easy to maintenance, fire prevention, fire-retardant, dustproof three-phase thin insulating epoxy cast dry transformer are provided, it comprises the low pressure winding, high pressure winding and iron core, they dress up the device body by insulation of device body and lead wire set, and the low pressure winding adopts the Copper Foil coiling; The high pressure winding adopts four sections winding structures, and its intersegmental and end face filled glass fiber weak point is cut felt, and its interlayer adopts two layers of soft type grid cloth; The described Pyatyi stepping laminar that adopts unshakable in one's determination.
The beneficial effects of the utility model: structure is attractive in appearance, stable performance, low noise, low office put, energy-conservation; Easy to maintenance, dustproof, antifog, fire prevention; Pollution-free, life termination is waited recyclable utilization.
Be embodied in:
1, the low pressure winding adopts the Copper Foil coiling, and the efficient height is easy to operate.
2, high-tension coil adopts four sections winding structures, is arranged as 1-3-2-4, earlier around the 1-3 section, turns mould then around the 2-4 section, is convenient to the tap region outlet.
3, the intersegmental and end face filled glass fiber weak point of high-tension coil is cut felt, and interlayer adopts two layers of soft type grid cloth, effectively reduces the cracking of epoxy resin and the office of product and puts.
4, iron core adopts Pyatyi stepping laminar and adopts the low-loss silicon steel sheet, effectively reduces no-load loss and noise.
