Abstract
The invention discloses a power transformer, particularly relates to a three-dimensional reel iron core 20kV dry type wind power transformer. The three-dimensional reel iron core 20kV dry type wind power transformer is characterized by comprising a device body, wherein an upper clamping piece is arranged at the top end of the device body, a lower clamping piece is arranged at the bottom end of the device body, a plurality of high-voltage terminals, a plurality of low-voltage terminals and a linkage type low-voltage wire connection copper plate are arranged on the upper clamping piece, and an intelligent cooling fan is arranged on the lower clamping piece. As the three-dimensional reel iron core 20kV dry type wind power transformer adopts a three-dimensional reel iron core structure, a three-phase iron core magnetic path is balanced completely, and the no-load loss and the production cost are greatly reduced; furthermore, the overall volume is small, and the use is safer, more economic and more reliable.
Description
(1) technical field
The present invention relates to a kind of power transformer, particularly a kind of 3 D stereo volume iron core 20kV dry type wind power transformer.
(2) background technology
At present, oil immersed type that uses in the wind power generation of 20KV grade or dry-type transformer iron core all are to occur with stacked form, three-phase iron circuit imbalance, magnetic circuit is longer, thereby loss is bigger, and no-load current is bigger, and noise is bigger, the silicon steel sheet large usage quantity, production cost is also along with the consumption of material increases greatly simultaneously.Thereby the volume of transformer is bigger.And non-crystaline amorphous metal transformer manufacturing cost is higher, and technology is more complicated also, and maintainability is poor, and directly the cost of investment to wind-powered electricity generation also increases greatly.More than 2 air pollution that all easily produce and the consumption of the energy cause waste.
(3) summary of the invention
The present invention is in order to remedy the defective of prior art, provides that a kind of no-load loss is low, volume is little, the 3 D stereo of low cost of manufacture volume iron core 20kV dry type wind power transformer.
The present invention is achieved through the following technical solutions:
A kind of 3 D stereo volume iron core 20kV dry type wind power transformer, it is characterized in that: comprise the device body, device body top is provided with upper clamping piece, device body bottom is provided with lower clamping piece, upper clamping piece is provided with several HV Terminal, several low-voltage terminals and articulated low pressure wiring copper coin, and lower clamping piece is provided with intelligent cooling blower.
This 3 D stereo volume iron core 20kV dry type wind power transformer, described device body comprises iron core and winding, described iron core is the 3 D stereo coiled core.Described winding comprises high pressure winding and low pressure winding.Described winding is sealed two kinds of forms for sealing with non-.The junction of described iron core and upper clamping piece, lower clamping piece is provided with crash roll.Described transformer is equipped with shell, and the shell protection grade is more than the IP40.
The invention has the beneficial effects as follows: this 3 D stereo volume iron core 20kV dry type wind power transformer, owing to adopt the three-dimensional rolled iron core structure, make tri-phase iron core magnetic circuit complete equipilibrium, greatly reduce no-load loss and production cost, and overall volume is little, uses safer, economical, reliable.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing 1 is looked schematic diagram for master of the present invention.
Accompanying drawing 2 is a schematic top plan view of the present invention.
Accompanying drawing 3 is an internal structure schematic diagram of the present invention.
Among the figure, 1 device body, 11 iron cores, 12 windings, 121 high pressure windings, 122 low pressure windings, 2 upper clamping pieces, 3 lower clamping pieces, 4 HV Terminal, 5 low-voltage terminals, 6 articulated low pressure wiring copper coins, 7 intelligent cooling blowers.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This 3 D stereo volume iron core 20kV dry type wind power transformer, it is characterized in that: comprise device body 1, device body 1 top is provided with upper clamping piece 2, device body 1 bottom is provided with lower clamping piece 3, upper clamping piece 2 is provided with several HV Terminal 4, several low-voltage terminals 5 and articulated low pressure wiring copper coin 6, and lower clamping piece 3 is provided with intelligent cooling blower 7.Described device body 1 comprises iron core 11 and winding 12, and described iron core 11 is the 3 D stereo coiled core.Described winding 12 comprises high pressure winding 121 and low pressure winding 122.Described winding 12 is sealed two kinds of forms for sealing with non-.Described iron core 11 is provided with crash roll with the junction of upper clamping piece 2, lower clamping piece 3.Described transformer is equipped with shell, and the shell protection grade is more than the IP40.
This 3 D stereo volume iron core 20kV dry type wind power transformer, because iron core 11 structures adopt 3 D stereo volume iron core, its no-load loss is than the conventional planar structure appendiron core transformer low about 60% of identical electric pressure and capacity, than planar structure reel iron core transformer low 40%, no-load current is than national standard low 80%, noise reduces by 7 ~ 10db(A), save the silicon steel sheet more than 20%, save 2-3% copper consumption, its cost has reduced more than 30% than non-crystaline amorphous metal, and tri-phase iron core magnetic circuit complete equipilibrium, greatly reduce no-load loss and production cost.The above-mentioned good energy-conservation environment protecting that played simultaneously adopts more than the shell protection grade IP40, has dustproof efficiently effect, is fit to particular surroundings simultaneously and requires to use.If this transformer coil uses the epoxide resin material moulding by casting, moisture resistance, dust-fast, heat-resisting and difficult combustion is more arranged, characteristic such as put out certainly, can operate as normal under various mal-conditions such as short-circuit current rush, stable excellent insulation property, safety, economic, reliable, convenient.
