Abstract

The utility model provides a noise reduction device on an amorphous alloy transformer. A buffer device is arranged on the lower part of an amorphous alloy iron core and hung on a coil, thus the technology structure design of the existing amorphous alloy transformer is accorded, the structure is simple, the production cost is low, the shake between multi-layers of iron cores is effectively avoided, so as to reduce the noise generated during the operation of the transformer at the source and obtain an obvious noise reduction effect.

Description

Noise-decreasing device on a kind of amorphous alloy transformer

Technical field

The utility model relates to a kind of amorphous alloy transformer, the noise-decreasing device on particularly a kind of amorphous alloy transformer.

Background technology

Metal is after fusing, and inner atom is in active state, once metal begins to cool down, atom will be along with decrease of temperature, and lines up in an orderly manner according to certain crystalline state rule at leisure, forms crystal.If cooling procedure is very fast, atom also has little time just to arrange again and has been solidified, and has just produced amorphous alloy thus; Non-crystaline amorphous metal is made the transformer that iron core forms, and the no-load loss (when referring to the transformer secondary output open circuit, in the elementary power loss that records) that it makes appendiron core transformer than silicon steel sheet descends about 80%; No-load current is (during the transformer secondary output open circuit; Elementaryly still have certain electric current, this part electric current is called no-load current) descend approximately 85%, be the comparatively ideal distribution transformer of present energy-saving effect.But non-crystaline amorphous metal in working order down can be because huge noise be sent in vibrations; The general traditional process structure of amorphous alloy transformer does not consider that thereby the characteristic of non-crystaline amorphous metal makes that the transformer noise of producing is very big, does not meet environmental requirement at present.

Summary of the invention

In order to overcome the deficiency of prior art, the utility model provides the noise-decreasing device on a kind of amorphous alloy transformer.

The utility model solves the technical scheme that its technical problem adopted:

Noise-decreasing device on a kind of amorphous alloy transformer; Comprise casing; Box house is hung with the working group that is made up of some amorphous alloy iron cores; Being arranged with coil on the said amorphous alloy iron core, conflicts and is provided with buffer unit in the amorphous alloy iron core bottom, and said buffer unit is suspended on the coil through the hole for hoist of its both sides;

As the improvement of such scheme, described buffer unit is superimposed by cardboard and corrugated board and forms, and said cardboard is positioned at two outsides of buffer unit;

As the further improvement of such scheme, said corrugated board is the hump shape structure.

The beneficial effect of the utility model is: the utility model is through being provided with buffer unit in the amorphous alloy iron core bottom; And hang and be located on the coil; Both met the process structure design of existing amorphous alloy transformer, simple in structure and cost of manufacture is low, and can effectively prevent the vibrations between the multilayer iron core; Reduced the noise that produces the transformer work from the source, effect is obvious.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the front view of the buffer unit of the utility model;

Fig. 3 is the upward view of Fig. 2.

Embodiment

With reference to Fig. 1 ~ 3; Noise-decreasing device on a kind of amorphous alloy transformer; Comprise casing 1, casing 1 inside is hung with the working group that is made up of some amorphous alloy iron cores 2, is arranged with coil 3 on the said amorphous alloy iron core 2; Conflict and be provided with buffer unit 4 in amorphous alloy iron core 2 bottoms, said buffer unit 4 is suspended on the coil 3 through the hole for hoist 5 of its both sides.

Described buffer unit 4 is superimposed by cardboard 41 and corrugated board 42 and forms, and said cardboard 41 is positioned at two outsides of buffer unit 4.Said corrugated board 42 is the hump shape structure, and the vibrations that the hump shape structure can efficient buffer amorphous alloy iron core 2, vibrations reduce then that noise also can reduce thereupon.

The utility model is through being provided with buffer unit 4 in amorphous alloy iron core 2 bottoms; And hang and be located on the coil 3; Both met the process structure design of existing amorphous alloy transformer, simple in structure and cost of manufacture is low, and can effectively prevent the vibrations between the multilayer iron core; Reduced the noise that produces the transformer work from the source, effect is obvious.

Certainly, the utility model is not limited to above-mentioned execution mode, as long as it reaches the technique effect of the utility model with essentially identical means, all should belong to the protection range of the utility model.
