Description
Technical field
The utility model relates to transformer technology field, particularly relates to a kind of low noise dry-type transformer.
Background technology
Dry-type transformer, for oil-filled transformer, is the transformer that a kind of iron core and winding are not immersed in iknsulating liquid, is generally used for hospital, school, residential quarters, industrial and mining enterprises.The fluctuation of service of dry-type transformer or when damaging mainly transformer long-play load increase or electric power system fault time transformer winding temperature exceed the heat-resistant limit of insulating material and make insulation failure, thus transformer is broken down.Existing dry-type transformer adopts perforation structure to fix due to iron core, and noise is comparatively large, produces noise pollution to operational environment.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of low noise dry-type transformer, can solve the technical problem that existing dry-type transformer noise is large.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of low noise dry-type transformer, comprise protective housing, iron core, low-voltage coil and high-tension coil, described iron core vertical internal is in described protective housing, and described low-voltage coil and high-tension coil are nested with successively on described iron core; Described iron core is three-dimensional laminated structure, and the left and right sides of its top and bottom adopts feet clamping in described protective housing, its top and be provided with elastic cushion block between bottom and described protective housing; Be provided with insulating barrier between described low-voltage coil and high-tension coil, in described insulating barrier, be evenly provided with air flue, describedly often between adjacent two air flues, a cross-over block is set.
In the utility model preferred embodiment, described feet is the iron feet of L-type structure, and it is fixed on by hanging screw rod on the internal face of described protective housing, and the contact-making surface of itself and described iron core is bonded with rubber layer.
In the utility model preferred embodiment, described elastic cushion block is the wooden unit of rubber coated.
In the utility model preferred embodiment, described insulating barrier is crosslinked polyetylene insulated layer.
In the utility model preferred embodiment, described air flue is longitudinal corrugated type or arc.
In the utility model preferred embodiment, the number of described air flue is even number.
In the utility model preferred embodiment, the upper region between feet of four peripheral wall surfaces of described protective housing all offers shutter.
In the utility model preferred embodiment, the height of described shutter accounts for 1/3 ~ 1/2 of described protective housing wall face height.
The beneficial effects of the utility model are: a kind of low noise dry-type transformer of the utility model, structure is simple, reasonable in design, its by core structure, modes of emplacement and and transformer protective housing between fixed form, effectively prevent transformer and in use produce vibration, thus reduce noise, improve the useful life of transformer.
Accompanying drawing explanation
Fig. 1 is the perspective view of a kind of low noise dry-type transformer of the utility model;
Fig. 2 is the schematic top plan view of shown iron core and coil;
In accompanying drawing, the mark of each parts is as follows: 1. protective housing, and 101. shutters, 2. iron core, 3. low-voltage coil, 4. high-tension coil, 5. feet, 6. elastic cushion block, 7. hang screw rod, 8. rubber layer, 9. crosslinked polyetylene insulated layer, 10. air flue, 11. cross-over blocks.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model.
Refer to accompanying drawing, the utility model embodiment comprises:
The utility model discloses a kind of low noise dry-type transformer, comprise protective housing 1, iron core 2, low-voltage coil 3 and high-tension coil 4, described iron core 2 is the three-dimensional laminated structure that multiple iron plate is formed, vertical internal is in described protective housing 1, the left and right sides of its top and bottom adopts feet 5 clamping in described protective housing 1, its top and be provided with elastic cushion block 6 between bottom and described protective housing 1, this elastic cushion block is the wooden unit of rubber coated; Described feet 5 is the iron feet of L-type structure, and it is fixed on by hanging screw rod 7 on the internal face of described protective housing 1, and the contact-making surface of itself and described iron core 2 is bonded with rubber layer 8.The structure of iron core and and protective housing between fixed relationship can effectively avoid it to produce in protective housing vibrating or wear and tear, thus reduce noise, and improve useful life.
Described low-voltage coil 3 and high-tension coil 4 are nested with successively on described iron core 2; And between low-voltage coil 3 and high-tension coil 4, be provided with crosslinked polyetylene insulated layer 9, the air flue 10 of even number (2,4,6 ¨ ¨ ¨) longitudinal corrugated type or arc is evenly provided with in insulating barrier, to increase air circulation, promote heat radiation, thus improve the heat resistance of Transformer Winding, often between adjacent two air flues, a cross-over block 11 is set.
In addition, the shutter 101 accounting for wall face height 1/3 ~ 1/2 is also offered in the upper region between L-type feet 5 of four peripheral wall surfaces of described protective housing 1, the effect of offering shutter 101 is, be conducive on the one hand scattering and disappearing of heat in transformer, symmetric design is conducive to cross-ventilation heat radiation on the other hand, strengthens the high temperature-proof performance of transformer.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
