Abstract
The utility model discloses a low-noise amorphous alloy iron-core transformer. The transformer is characterized in that a cushion block is arranged between a lower iron yoke and a lower clamping piece of the amorphous alloy iron-core; and a position regulating mechanism for regulating the tightness of the cushion block is arranged on the lower clamping piece. The cushion block is additionally mounted at the joint of the iron-core, thereby effectively reducing the noise of the transformer; and furthermore, the transformer has the advantages of simple structure and good noise reduction effect.
Description
Technical field
The utility model relates to the transformer technology field, relates to a kind of amorphous alloy core transformer in particular.
Background technology
The non-crystaline amorphous metal that grows up from the fifties, as a kind of high-efficiency and energy-saving type material, enter the nineties after, on distribution transformer, stepped into the practicability stage.Up to now, existing 600,000 Amorphous Alloy Core Transformer (hereinafter to be referred as amorphous transformer) in the whole world are moved on electrical network, and what wherein running time was the longest reaches 20 years, and domestic existing a spot of amorphous distribution transformer and amorphous box-type substation put into operation.Though, utilize the outstanding non-crystaline amorphous metal of magnetic property to make the iron core of transformer, 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 as transformer: well-known, noise of transformer comes from transformer core magnetostriction and vibration of causing under alternating flux.The principal element of decision noise height is magnetic flux density and the 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 amorphous alloy core is not suitable for excessive clamping, and therefore, the noise of amorphous transformer will be higher than the silicon steel sheet transformer.The power department in Europe was once done two class noise of transformer comparative tests, and the result shows that the sound level of amorphous transformer is than the high 6-8dB of silicon steel sheet transformer of similar specification.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
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, and loss is little, and the amorphous alloy core transformer of the low noise of dependable performance.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of amorphous alloy core transformer of low noise, it is characterized in that: between the lower yoke of described amorphous alloy core and the lower clamping piece cushion block is set, lower clamping piece is provided with the position adjusting mechanism of regulating this cushion block degree of tightness.
As further specifying of such scheme, described position adjusting mechanism comprises the stiffener that evenly is welded in the lower clamping piece upper surface more than eight and is distributed in the check washer and the bolt of lower clamping piece lower surface.
Described stiffener is the steel plate of thickness 3~5mm, and bolt adopts the M10 bolt.
Be provided with the groove that matches with the stiffener size in the described cushion block, stiffener is embedded in this groove.
Described cushion block pad is below the seam areas of amorphous alloy core, and its thickness is 8~12mm.
Described cushion block is the lamination wood block filler.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model tights a bolt by the diagonal angle, regulates the lamination wood block filler, accomplishes to regulate the degree of tightness of amorphous alloy core seam, to reach the purpose that reduces noise.

Embodiment
As depicted in figs. 1 and 2, the amorphous alloy core transformer of a kind of low noise of the utility model is provided with cushion block 4 between lower yoke of amorphous alloy core 1 (seam areas is arranged) and the lower clamping piece 3, and lower clamping piece 3 is provided with the position adjusting mechanism 5 of regulating this cushion block degree of tightness.Wherein, this position adjusting mechanism 5 is made of the stiffener 7 that evenly is welded in the lower clamping piece upper surface more than eight and the check washer and the bolt that are distributed in the lower clamping piece lower surface, be provided with groove 6 in the cushion block 4, stiffener is embedded in this groove 6, after the device body stands up, tighten the M10 bolt, regulate the lamination wood block filler by the diagonal angle, accomplish to regulate the degree of tightness of amorphous alloy core seam, to reach the purpose that reduces noise.
Above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that.Still can make amendment or the part technical characterictic is equal to replacement the embodiment of utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
