Abstract
The invention provides a novel technology low-noise dry iron reactor which is composed of a support, a coil winding, an iron yoke, an iron core clamping plate and an iron core pillar. The coil winding is assembled on the outer side of the iron core pillar. The novel technology low-noise dry iron core reactor is characterized in that an iron core of the reactor and a punched air gap plate are bonded to form an integral structure through a high-shearing-strength (the shearing strength reaches 20 MPa)/high-hardness (the Shore hardness reaches 85) double-component epoxy adhesive in a curing mode at the normal temperature. The novel technology low-noise dry iron reactor is simple in structure, low in production cost, convenient to use, stable in performance, capable of effectively lowering the noise of the iron core of the reactor and capable of being widely applied to the technical field of dry rectors.
Description
Technical field:
The present invention relates to a kind of reactor technology, particularly relate to a kind of new technology 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 primarily of 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.
Summary of the invention:
The object of the invention is to solve prior art Problems existing, provide a kind of new technology low noise reactor with T-shaped core.For achieving the above object, the present invention adopts following technical scheme:
The invention provides the dry type core structure reactor that a kind of noise of adopting new technology is lower.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 present invention has and good effect are:
1. the invention 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 double-component epoxy adhesive namely curable at normal temperatures for the air gap plate of iron core of the present invention and punching, technological operation optimization, reduces production cost.
3. structure of the present invention 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.
