Abstract
The invention discloses a dry type distribution transformer which comprises a first winding and a second winding which are arranged on an iron core. The dry type distribution transformer is characterized in that the number of turns of the previous layer of the first winding is one turn less than the number of turns of the posterior layer of the first winding in the coiling process of a coil, and the number of turns of each layer is decreased progressively with the increase of the number of layers; the number of turns of the previous layer of the second winding is one turn more than the number of turns of the posterior layer of the second winding in the coiling process of a coil and the number of turns of each layer is increased progressively with the increase of the number of layers; and the first winding is arranged close to the second winding; and intersection spaces are filled with insulating materials during the coiling process. The dry type distribution transformer has the advantage that the size is reduced since the first winding is arranged close to the second winding. An SCB11-1600/35/0.4KV dry type distribution transformer has no-load loss less than 2880W, no-load current less than 0.4%, load loss less than 14670W, which are all superior to those in standard GB/T10228-2008, therefore the dry type distribution transformer is an ideal energy-saving consumption-reduction transformer product.
Description
Technical field
The present invention relates to a kind of transformer, the dry-type distribution transformer that particularly a kind of volume is little, energy-saving and cost-reducing belongs to the power transmitting device technical field.
Background technology
At present, along with the low-carbon environment-friendly rapid development of economy, the loss and the consumptive material that reduce transformer are more and more important; Existing dry-type distribution transformer shown in accompanying drawing 1, comprises a plurality of windings 1 usually, and said winding 1 is wrapped on the iron core; Each winding 1 last layer in the coil winding process lacks around 1 circle than following one deck, and along with the increase of the number of plies, every layer of number of turn successively decreased; Each winding 1 forms trapezoidal shape; The arrangement mode of adjacent winding is the same; Coiling finishes the back and tamps intersegmental with insulating material; The dry-type distribution transformer that the winding of this structure forms, volume is big, and energy consumption is high.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed little, the energy-saving and cost-reducing dry-type distribution transformer of a kind of volume.
Technical solution of the present invention is achieved in that a kind of dry-type distribution transformer, comprises first winding, second winding, and said winding is on iron core; Said first winding last layer in the coil winding process lacks around 1 circle than following one deck, and along with the increase of the number of plies, every layer of number of turn successively decreased; Said second winding last layer in the coil winding process is Duoed around 1 circle than following one deck, and along with the increase of the number of plies, every layer of number of turn increases progressively; The adjacent setting of said first winding with second winding; Coiling is tamped intersegmental with insulating material simultaneously.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The setting that links to each other with second winding of dry-type distribution transformer of the present invention, first winding can reduce the volume of dry-type distribution transformer, and the no-load loss value of the dry-type distribution transformer of SCB11-1600/35/0.4KV is less than 2880W simultaneously; No-load current is less than 0.4%; Load loss is less than 14670W, and all fortune is superior to the GB/T10228-2008 standard, is a desirable energy-saving and cost-reducing transformation product.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Fig. 1 is the winding distribution schematic diagram of the dry-type distribution transformer of prior art;
Fig. 2 is the winding distribution schematic diagram of dry-type distribution transformer of the present invention;
Wherein: 1, winding; 10, first winding; 11, second winding.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be depicted as a kind of dry-type distribution transformer of the present invention like accompanying drawing 2, comprise first winding 10, second winding 11, said winding is on iron core; Said first winding 10 last layer in the coil winding process lacks around 1 circle than following one deck, and along with the increase of the number of plies, every layer of number of turn successively decreased; Said second winding 11 last layer in the coil winding process is Duoed around 1 circle than following one deck, and along with the increase of the number of plies, every layer of number of turn increases progressively; Said first winding 10 and the 11 adjacent settings of second winding; Coiling is tamped intersegmental with insulating material simultaneously.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The setting that links to each other with second winding of dry-type distribution transformer of the present invention, first winding can reduce the volume of dry-type distribution transformer, and the no-load loss value of the dry-type distribution transformer of SCB11-1600/35/0.4KV is less than 2880W simultaneously; No-load current is less than 0.4%; Load loss is less than 14670W, and all fortune is superior to the GB/T10228-2008 standard, is a desirable energy-saving and cost-reducing transformation product.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
