Abstract

The utility model provides a roll up dry-type transformer unshakable in one's determination belongs to the power equipment field, and its structure includes the folder and establishes folder under the high-low pressure on the base, goes up folder and high-low pressure down and is equipped with unshakable in one's determination and high-voltage winding and low-voltage winding around on the iron-cored column between the folder, go up folder and high-low pressure down folder and pass through U type screw rod and connect, unshakable in one's determination and adopted the cross section approximate circular shape book unshakable in one's determination, high-voltage winding adopts continuous type winding, low-voltage winding to adopt the low pressure foil to wind, adopts ceramic cushion. The wound core dry-type transformer of the utility model has the advantages that the core does not need to consume the magnetization capacity of the joint, and the magnetic circuit has no air gap, so that the excitation current is greatly reduced, and the no-load current is small and the no-load loss is low; the wound core is a seamless whole, so that the noise level during operation is greatly reduced, and the environment is protected; the wound core transformer makes full use of the orientation of the silicon steel sheet, and eliminates the loss increased by the inconsistency of the magnetic circuit and the orientation of the silicon steel sheet.

Description

A kind of rolled iron core dry-type transformer
(1) technical field
The utility model relates to a kind of power equipment, specifically a kind of rolled iron core dry-type transformer.
(2) background technology
In recent years, dry-type transformer obtains swift and violent development in the whole nation, and it is simple in structure because of having, easy to maintenance, fire protection flame retarding, advantage such as dustproof, is widely used in the occasion that safe operation is had higher requirements.At present; The cast-type dry-type transformer is used more extensive, uses dry-type transformer the earliest though the dry-type transformer of SG type is exploitation, and the dry-type transformer of Yin Putong is moistureproof, anti-dust performance is poor; Its application is restricted; Along with the improvement of external high performance insulating material and manufacturing process, each item performance index of the dry-type transformer of SG type have all reached cast-type and have done the level that becomes, for its development has brought good development opportunity.
(3) summary of the invention
The technical assignment of the utility model is the deficiency to prior art, and a kind of rolled iron core dry-type transformer is provided.
The utility model solves the technical scheme that its technical problem adopted:
A kind of rolled iron core dry-type transformer; Comprise upper clamping piece and be located at the high-low pressure lower clamping piece on the base; Be provided with iron core and high pressure winding and low pressure winding on the core limb between upper clamping piece and the high-low pressure lower clamping piece, said upper clamping piece is connected through U type screw rod with the high-low pressure lower clamping piece, and iron core has adopted the volume of cross section sub-circular unshakable in one's determination; The high pressure winding adopt continous way winding, low pressure winding adopt low blocking around; Interlayer adopts ceramic cushion block, and coil support all adopts ceramic insulator, the overall vacuum impregnated structures.
Above-mentioned volume iron core is made up of two rectangle inner iron core and outer iron cores outside their arranged side by side, and the inner iron core cross section is protruding from outer inwardly semicircular in shape, and outer cross section unshakable in one's determination is the semicircular in shape convexity from inside to outside, and the volume that is combined into the cross section sub-circular is unshakable in one's determination.
A kind of rolled iron core dry-type transformer of the utility model compared with prior art, the beneficial effect that is produced is:
1) iron core need not to consume the magnetization capacity of seam, does not have air gap in the magnetic circuit, significantly reduces exciting curent, so no-load current is little, no-load loss.
2) the volume iron core self is a jointless integral body, and the noise level when operation reduces greatly, helps protecting environment.
3) Wound iron-core transformer has made full use of the orientation of silicon steel sheet, has eliminated because of magnetic circuit and the inconsistent loss that increases of silicon steel sheet orientation.
