Abstract
The invention relates to the technical field of power transformers and in particular relates to a three-phase rolled iron core fully sealed power transformer. The three-phase rolled iron core fully sealed power transformer comprises a transformer body, a corrugated plate oil tank and a closed overall iron core, wherein the closed overall iron core is formed by continuously winding a silicon steel strip; the section of the closed overall iron core is purely circular. By adoption of the structure, the joint air-gap of the traditional iron core is reduced, so that the noise of the product is obviously lowered; compared with the same-capacity transformer, the transformer has the advantages that the no-load loss is reduced by 30 percent, the no-load current is reduced by 70 percent, the noise is lowered by about eight decibels, and moreover, the iron core is totally mechanically machined, the labor intensity is lightened, and the product quality is stable and is improved. In addition, the three-phase rolled iron core fully sealed power transformer has the characteristics of reasonable design, simple structure, small occupied area, attractive appearance and the like.
Description
Technical field
The present invention relates to the power transformer technical field, be specifically related to three-phase volume iron core Full-sealed power transformer.
Background technology
At present, the iron core of existing power transformer usually adopts manually each plates to be docked and forms the sheet rectangle iron core, at thickness last layer one deck stack, but there is following problem in above-mentioned this mode: the course of processing very complex of 1, shearing, docking and lamination, inefficiency; 2, the iron core seam is many, and seam causes that magnetic resistance is large, loss is high, noise is large, energy-conservation and environment protecting is poor.
Summary of the invention
The three-phase volume iron core Full-sealed power transformer that the purpose of this invention is to provide a kind of constant product quality, magnetic resistance is little, loss is low, noise is little, energy-conservation and environment protecting is good.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: three-phase volume iron core Full-sealed power transformer, comprise transformer body, corrugated plating fuel tank and enclosed type integrated iron core, described enclosed type integrated iron core is formed by the silicon strip continuous coiling, and the cross section of described enclosed type integrated iron core is pure circle.
Further, described corrugated plating fuel tank is hermetically sealed fuel tank.
The present invention has following beneficial effect: three-phase volume iron core Full-sealed power transformer of the present invention, mainly comprise transformer body, corrugated plating fuel tank and enclosed type integrated iron core, wherein, the enclosed type integrated iron core is formed by the silicon strip continuous coiling, and the cross section of enclosed type integrated iron core is pure circle; The present invention adopts said structure, reduced the seam air gap of traditional iron core, so that the noise of product significantly decreases, this product with compare no-load loss with capacity type and descend 30%, no-load current descends 70%, and noise descends about 8 decibels, and iron core processing full mechanization, reduce labor intensity, constant product quality also increases.In addition, the present invention has reasonable in design, simple in structure, the characteristics such as floor space is little, good looking appearance.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, three-phase volume iron core Full-sealed power transformer comprises transformer body 1, corrugated plating fuel tank 2 and enclosed type integrated iron core 3, and described enclosed type integrated iron core 3 is formed by the silicon strip continuous coiling, and the cross section of described enclosed type integrated iron core 3 is pure circle.Wherein, described corrugated plating fuel tank 2 is hermetically sealed fuel tank.In the present embodiment, the enclosed type integrated iron core is formed by the silicon strip continuous coiling, reduced the seam air gap of traditional iron core, so that the noise of product significantly decreases, and silicon strip is after annealing in process, with compare no-load loss with capacity type and descend 30%, no-load current descends 70%, and noise descends about 8 decibels, and its high and low coil is directly on iron core, two coil good concentricity, the Short Circuit withstand sexuality is good.In addition, in the present embodiment, the cancellation oil conservator adopts the corrugated plating fuel tank, and the flexible adjustment that the oil volume that temperature causes changes by corrugated plate completely cuts off transformer oil and air, thereby has prolonged the useful life of product.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, other modifications that those of ordinary skills make technical scheme of the present invention or be equal to replacement, only otherwise break away from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
