Technical field
The utility model relates to the transformer technology field, relates to the amorphous alloy iron core oil-immersed formula transformer of a kind of low noise in particular.
Background technology
Non-crystaline amorphous metal has outstanding magnetic property, and the iron core of available manufacturing transformer finally can obtain very low loss value.But non-crystaline amorphous metal has brought a lot of difficulties but for the design and the manufacturing of transformer.Noise problem like transformer: noise of transformer comes from transformer core magnetostriction and vibration of causing under alternating flux.The principal element of decision noise height is the magnetic flux density and clamping degree unshakable in one's determination in the iron core.Because the magnetostriction degree of non-crystaline amorphous metal is high more about 10% than silicon steel sheet, and the suitable excessively clamping of amorphous alloy core, therefore, the noise of amorphous transformer will be higher than the silicon steel sheet transformer.Oil-filled transformer is to be immersed in the transformer in the iknsulating liquid to unshakable in one's determination and winding, is main insulating means with oil, relies on oil to make coolant, and oil-filled transformer has been widely used in each controller switching equipment.Along with deepening continuously of China's upgrading urban and rural power grids construction, high-power transformer gets into the residential block just more and more, and is especially in the majority with the oil-filled transformer of 110kV electric pressure.We know, all can produce noise during the transformer operation, and this noise is the comparatively responsive single-frequency noise of people's ear, and is bigger to people's harm.Oil-filled transformer is installed near dwelling house or the public place, and near the resident making receives the annoying noise jamming of continuous upgrading.In this case, the vibration of transformer and noise problem more and more cause people's great attention.For this reason, how to solve amorphous alloy iron core noise of transformer problem and become the problem that people are worth discussion.
Summary of the invention
For overcoming above deficiency, the utility model provides a kind of low noise amorphous alloy iron core oil-immersed formula transformer, can effectively lower the amorphous alloy iron core noise of transformer, and is simple in structure, excellent noise reduction effect.
The technical solution of the utility model is: the amorphous alloy iron core oil-immersed formula transformer of a kind of low noise; Mainly form by fuel tank, folder, amorphous alloy iron core, pitch of the laps, sound-absorbing offset plate, sound insulation steel plate; It is characterized in that: cushioning sound-absorbing offset plate between at the bottom of said amorphous alloy iron core, lower clamping piece, the fuel tank; In fuel tank, install the sound insulation steel plate additional, single amorphous alloy iron core two surfaces are covered with coating.
Cushioning sound-absorbing offset plate between said amorphous alloy iron core bottom and the folder inboard.
Cushioning sound-absorbing offset plate between survey and the fuel tank bottom outside the said folder bottom.
The sound-absorbing offset plate is placed in junction between said upper clamping piece and the fuel tank case lid.
Described sound-absorbing offset plate two sides is evenly distributed with the plastic cement particle.
Add the sound insulation steel plate in the said fuel tank.
Said sound insulation steel plate is to be combined by two thick steel plates of 1mm.
The epoxy thickness of said amorphous alloy iron core two surface-coated is 1mm.
The beneficial effect of the utility model is: through cushioning sound-absorbing offset plate between at the bottom of amorphous alloy iron core, folder, the fuel tank; In fuel tank, install the sound insulation steel plate additional, attenuate iron core surface is covered with coating, effectively lowers the amorphous alloy iron core noise of transformer; Simple in structure, excellent noise reduction effect.

Embodiment
As shown in the figure; The amorphous alloy iron core oil-immersed formula transformer of a kind of low noise; Mainly form by fuel tank 1, folder 2, amorphous alloy iron core 3, pitch of the laps 4, sound-absorbing offset plate 5, sound insulation steel plate 6; It is characterized in that: said amorphous alloy iron core 3, folder 2, fuel tank cushioning sound-absorbing offset plate 5 at 1 end, install sound insulation steel plate 6 additional for 1 li at fuel tank, 3 liang of surfaces of single amorphous alloy iron core are covered with coating 7.
Cushioning sound-absorbing offset plate 5-1 between said amorphous alloy iron core 3 bottoms and folder 2 inboards.
Cushioning sound-absorbing offset plate 5-2 between survey and fuel tank 1 bottom outside said folder 2 bottoms.
Sound-absorbing offset plate 5-3 is placed in junction between said upper clamping piece 2 and fuel tank 1 case lid.Cut off sound generation source.
Described sound-absorbing offset plate 5 two sides are evenly distributed with plastic cement particle 8.
Said fuel tank adds sound insulation steel plate 6 for 1 li.
Said sound insulation steel plate 6 is to have the steel plate of two thickness 1mm to combine usefulness, good springiness.The gilled radiator fuel tank is the sound insulation steel plate 6 that two fronts respectively tighten two 1mm with screw in fuel tank 1; Corrugated tank is at respectively the burn-on sound insulation steel plate 6 of two 1mm of fuel tank 1 interior four faces.
Overgauge 1mm is accomplished in the folded thick requirement of said amorphous alloy iron core 3, equals to increase the iron core effective cross-section like this and falls low magnetic density, thereby can reach the reduction exciting power.The epoxy thickness of 3 liang of surface-coated of single amorphous alloy iron core is reduced to 1mm by original 2mm, can reduce cost of manufacture like this, offset the cost that folded thick overgauge is had more.
Above embodiment only in order to the explanation the utility model technical scheme but not to its restriction; Be not to limit the utility model practical range with this; So all equivalences of doing according to the structure and the method for the utility model change, and all should be covered by within the utility model protection range.
