Abstract
The invention discloses a noise-reducing demagnetizing electric reactor which comprises an iron core post body and a coil, wherein the iron core post body is arranged in an insulating tube, the coil is wound around the iron core post body, the iron core post body is wrapped by a noise-reducing layer, the noise-reducing layer is wrapped by a tensile layer, and a shielding layer made of permeability magnetic materials is attached to the inner wall of the insulating tube. According to the noise-reducing demagnetizing electric reactor disclosed by the invention, through arranging a resin casting layer on the outside of the iron core post body, the noise and vibration generated by the electric reactor are greatly reduced; because the resin casting layer is wrapped by a tensile layer, a situation that the resin casting layer is cracked due to thermal expansion can be prevented; and because the shielding layer made of permeability magnetic materials is attached to the inner wall of the insulating tube, the electric reactor has a good shielding effect, good iron core saturation resistance and a low magnetic conductivity, thereby ensuring the quality of the electric reactor.
Description
Technical field
The present invention relates to the reactor field, particularly relate to a kind of noise reduction demagnetize reactor.
Background technology
Along with expanding economy, reactor is increasingly extensive in the application of every field, and reactor has the effects such as filtering, rectification, protective circuit, can the normal stable work of maintenance circuitry.
Existing iron-core reactor generally is comprised of core limb and coil.The problems such as yet existing iron-core reactor ubiquity noise is large, magnetic resistance is large, caloric value is large, fail safe is relatively poor.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of simple in structure, stability height, safe and reliable, can reduce the noise reduction demagnetize reactor of noise, reduction magnetic permeability, enhancing anti-saturation performance.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of noise reduction demagnetize reactor is provided, comprise and be arranged on the core limb body in the insulating cylinder and be wound on coil on the core limb body, described core limb body is coated with the noise reduction layer, described noise reduction layer is coated with the stretch-proof layer, and described insulating cylinder inwall is fitted with the screen of being made by permeability magnetic material.
In a preferred embodiment of the present invention, described noise reduction layer is the resin-cast layer, and noise reduction layer and core limb body are bonding by glue.
In a preferred embodiment of the present invention, described noise reduction layer thickness is 0.5-1mm.
In a preferred embodiment of the present invention, described stretch-proof layer thickness is 0.1-0.3mm.
In a preferred embodiment of the present invention, described screen is ferrite.
In a preferred embodiment of the present invention, described insulating cylinder is fastened by two identical semicircular cylinders and forms.
The invention has the beneficial effects as follows: noise reduction demagnetize reactor of the present invention is owing to be outside equipped with the resin-cast layer at the core limb body, greatly reduce noise and vibration that reactor produces, because at resin-cast layer outer cladding stretch-proof layer, can prevent that the resin-cast layer is owing to expanded by heating chaps, simultaneously, owing to be fitted with the screen of being made by permeability magnetic material at the insulating cylinder inwall, so that reactor has good shielding action, anti-iron core is saturated and lower magnetic permeability, has guaranteed the quality of reactor.
Description of drawings

The mark of each parts is as follows in the accompanying drawing: 1, insulating cylinder, 2, the core limb body, 3, coil, 4, the noise reduction layer, 5, the stretch-proof layer, 6, screen.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1, the embodiment of the invention comprises:
A kind of noise reduction demagnetize reactor, comprise and be arranged on the core limb body 2 in the insulating cylinder 1 and be wound on coil 3 on the core limb body 2, described core limb body 2 is coated with noise reduction layer 4, described noise reduction layer 4 is coated with stretch-proof layer 5, and described insulating cylinder 1 inwall is fitted with the screen 6 of being made by permeability magnetic material.
Described noise reduction layer 4 is the resin-cast layer, and noise reduction layer 4 thickness are 0.5-1mm, and noise reduction layer 4 is bonding by glue with core limb body 2.Resin-cast layer fixing behind the poured with epoxy resin after the solidifying and setting is high, and it is obvious to reduce noise effects.
Described stretch-proof layer 5 thickness are 0.1-0.3mm.Because reactor is when operation, core limb body 2 heat dissipation capacities are large, the resin-cast layer is easily softening even crack performance occurs, have a strong impact on the performance of reactor, the resin-cast layer is coated with the thermal deformation stress that stretch-proof layer 5 can effectively be eliminated the resin-cast layer, prevent that the resin-cast layer from chapping, and guaranteed the performance of reactor.
Described screen 6 is ferrite, and ferrite has good shielding action, has improved the anti-saturation performance unshakable in one's determination of reactor, has reduced magnetic permeability.
Described insulating cylinder 1 is fastened by two identical semicircular cylinders and forms, and easy installation and removal has made things convenient for maintenance.
Compared with prior art, noise reduction demagnetize reactor of the present invention is owing to be outside equipped with the resin-cast layer at core limb body 2, greatly reduce noise and vibration that reactor produces, because at resin-cast layer outer cladding stretch-proof layer 5, can prevent that the resin-cast layer is owing to expanded by heating chaps, simultaneously, owing to be fitted with the screen 6 of being made by permeability magnetic material at insulating cylinder 1 inwall, so that reactor has good shielding action, anti-iron core is saturated and lower magnetic permeability, has guaranteed the quality of reactor.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
