Abstract

The utility model discloses a low-noise reactor which comprises brackets, iron core columns and coil windings, wherein the coil windings are assembled on the outer sides of the iron core columns; each iron core column is formed in a way that porous clearance plates and silicon sheets are alternately arranged in a laminated manner; the porous clearance plates and the silicon sheets of each iron core column are bonded into a whole through an adhesive of which the shear strength is greater than 16 MPa and the Shore scleroscope hardness is greater than 70 degrees; and iron core clamp plates are arranged outside the iron core columns. The low-noise reactor provided by the utility model has the advantages of simple structure, convenience in use and stable property, effectively reduces the noise of the iron cores of a reactor and can be extensively applied to the technical field of dry reactors.

Description

The low noise reactor

Technical field

The utility model relates to a kind of reactor, relates in particular to a kind of low noise reactor.

Background technology

At present, existing reactor with T-shaped core comprises support, iron core column, coil windings, and winding coil is assemblied in the iron core column outside.Wherein, the core of reactor post is to be made of stacked silicon steel sheet and gap pad.The reactor noise is mainly stacked silicon steel sheet and the gap pad is subjected to attraction or the magnetostrictive stress that the magnetic flux change causes in the magnetic circuit, and generation vibration or mutual collision cause.Therefore, be necessary the iron core column of reactor is partly improved to reduce noise.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of low noise reactor, effectively reduces noise and simple in structure.

The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of low noise reactor, comprise support, iron yoke (forming), iron core column and coil windings by silicon steel sheet is overlapping, described coil windings is assemblied in the iron core column outside, wherein, described iron core column is formed by porous gap plate and silicon steel sheet intersecting, greater than 16Mpa, Shore hardness is whole greater than the bonding one-tenth of the bonding agent of 70 degree by shear strength for described porous gap plate and silicon steel sheet.

Above-mentioned low noise reactor, wherein, described iron core column is outside equipped with the iron core clamping plate.

The utility model contrast prior art has following beneficial effect: the low noise reactor that the utility model provides, porous gap plate and silicon steel sheet become whole by the bonding agent of high strength, high rigidity is bonding, reduce stacked silicon steel sheet and gap pad and be subjected to attraction or the magnetostrictive stress that the magnetic flux change causes in the magnetic circuit, thereby reduce the vibration or the collision mutually that produce, effectively reduced the iron core noise of reactor.

Embodiment

The utility model will be further described below in conjunction with drawings and Examples.

Fig. 1 is the utility model low noise reactor structural representation, and Fig. 2 is the utility model low noise core of reactor rod structure schematic diagram.

See also Fig. 1 and Fig. 2, the low noise reactor that the utility model provides comprises support 1, iron core column 2 and coil windings 3, described coil windings 3 is assemblied in iron core column 2 outsides, wherein, described iron core column 2 is formed by porous gap plate 5 and stem stem silicon steel sheet 6 intersectings, greater than 16Mpa, Shore hardness is whole greater than the bonding one-tenth of the bonding agent of 70 degree by shear strength for described porous gap plate and silicon steel sheet.

In order further to guarantee whole iron core column 2 reliably workings of bonding one-tenth, iron core column 2 is outside equipped with 4 fixations of iron core clamping plate.

Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection range of the present utility model is worked as with being as the criterion that claims were defined.
