Description
Technical field:
The utility model relates to a kind of reactor technology, particularly relates to a kind of low noise reactor with T-shaped core technical field.
Background technology:
The noise of electric equipment is the technical indicator that can not be ignored, and reactor is no exception, particularly iron core reactor.National standard has clear and definite regulation to noise, and iron core series reactor noise is 70dB, and noise of arc suppression coil is 78dB, and shunt reactor noise is 80dB, has also all done corresponding regulation to the noise objective of other type reactor.The height of noise objective indicates makers' designed capacity, also indicates makers' technological level.The not only contaminated environment of noise beyond target, and accumulate over a long period and will bring harm to the operation of electric equipment.
At present, existing reactor with T-shaped core is made up of support, coil windings, iron yoke, iron core clamping plate, iron core stem stem, and coil windings is assemblied in outside iron core stem stem, and wherein iron core stem for reactor is made up of iron core and air gap plate.The noise that reactor produces to cause by the variation of magnetic flux in magnetic circuit mainly due to stacked silicon steel sheet and air gap plate and attracts or stress that magnetostriction produces, and generation is vibrated or mutual collision is caused.In order to reduce stacked silicon steel sheet and air gap plate changes the attraction or magnetostrictive stress that cause by magnetic flux in magnetic circuit, the general rapid-curing cutback glue that adopts comes bonding iron core or the bonding iron core of employing single-component epoxy glue baking-curing.But in practical operation, because glue adhesive strength is too low or to take man-hour and production procedure too much because of needs baking-curing, when causing practical application, noise reduction is good or production cost is too high.
Utility model content:
The purpose of this utility model solves prior art Problems existing, provides a kind of Novel low-noise dry-type iron-core electric reactor.For achieving the above object, the utility model adopts following technical scheme:
The utility model provides the lower dry type core structure reactor of a kind of noise.Low noise reactor with T-shaped core is made up of support, coil windings, iron yoke, iron core clamping plate, iron core stem stem; Wherein coil windings is assemblied in outside iron core stem stem; Described iron core stem stem is by iron core and the bonding integrally structure of air gap plate.
Described its structure of air gap plate runs through punching, and then with high shear strength (shear strength reaches 20MPa)/high rigidity (Shore hardness reaches 85) double-component epoxy adhesive (normal temperature cure), iron core air gap plate and iron core are bonded into overall structure, thus reduce change by stacked silicon steel sheet and air gap plate the attraction or magnetostrictive stress that cause by magnetic flux in magnetic circuit, and generation vibration or mutually collide the noise caused.
The advantage that the utility model has and good effect are:
1. the utility model provides a kind of brand-new low noise reactor with T-shaped core, compared with existing dry reactor, its iron core stem stem upper core and the air gap plate of punching have employed high shear strength (shear strength reaches 20MPa)/bonding integrally structure of high rigidity (Shore hardness reaches 85) double-component epoxy adhesive (normal temperature cure).Adopt this technical scheme, decrease stacked silicon steel sheet and air gap plate changes the attraction or magnetostrictive stress that cause by magnetic flux in magnetic circuit, thus reduce the vibration that produces or mutually collide, effectively reduce the iron core noise of reactor.
2. to have employed two component epoxy adhesive namely curable at normal temperatures for the air gap plate of iron core described in the utility model and punching, technological operation optimization, reduces production cost.
3. the utility model structure is simple, and easy to use, stable performance, process operability is good, and production hour is short, and production technology cost is low, can be widely used in dry reactor technical field.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model will be further described:
Fig. 1 is the structural representation of a kind of Novel low-noise dry-type iron-core electric reactor of the utility model;
Fig. 2 is the structural representation of a kind of Novel low-noise dry-type iron-core electric reactor iron core of the utility model stem stem;
Fig. 3 is the structural representation of iron core and air gap plate in the utility model;
Reference numeral in each figure and the component names of correspondence as follows:
Wherein: 1 is support, 2 is coil windings, and 3 is iron yoke, and 4 is iron core clamping plate, and 5 is iron core stem stem, and 6 is iron core, and 7 is air gap plate.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further described.
As depicted in figs. 1 and 2, a kind of Novel low-noise dry-type iron-core electric reactor, be made up of support 1, coil windings 2, iron yoke 3, iron core clamping plate 4, iron core stem stem 5, coil windings 2 is assemblied in outside iron core stem stem 5, and the iron core 6 of its reactor adopts high shear strength/bonding integrally structure of high rigidity double-component epoxy adhesive (normal temperature cure) with the air gap plate 7 of punching.
The utility model provides the lower dry type core structure reactor of a kind of noise.Described its structure of air gap plate 7 runs through punching; And then with high shear strength (shear strength reaches 20MPa)/high rigidity (Shore hardness reaches 85) double-component epoxy adhesive (normal temperature cure), air gap plate 7 and iron core 6 are bonded into overall structure.Thus reduce and change by stacked silicon steel sheet and air gap plate 7 attraction or magnetostrictive stress that cause by magnetic flux in magnetic circuit, and the vibration produced or mutually collision cause noise.
It is namely curable at normal temperatures that the utility model iron core 6 and the air gap plate 7 of punching have employed two component epoxy adhesive, and technological operation optimization reduces production cost.
The elaboration of book according to the above description, the utility model those skilled in the art can also carry out suitable change and amendment to above-mentioned execution mode.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this specification, these terms just for convenience of description.
