Abstract
The utility model discloses an electric reactor capable of reducing noise and magnetic. The electric reactor capable of reducing noise and magnetic comprises a core leg body which is arranged in an insulating cylinder and a coil which winds on the core leg body, wherein a noise reduction layer is coated outside the core leg body, a stretch resistance layer is coated outside the noise reduction layer, and the inner wall of the insulating cylinder abuts against a shielding layer which is made of magnetic materials. The electric reactor capable of reducing noise and magnetic has the advantages of greatly reducing the noise and vibration made by the electric reactor due to a casting resin layer arranged outside the core leg body; being capable of avoiding the casting resin layer cracking caused by thermal expansion due to the stretch resistance layer coated outside the casting resin layer; being good in shielding effect, resisting the core saturation and being low in magnetic conductivity due to the shielding layer which is made of magnetic materials and abuts against the inner wall of the insulating cylinder and being good in quality.
Description
Technical field
The utility model relates to the reactor field, particularly relates 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.
The utility model content
The technical problem that the utility model 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 utility model 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 preferred embodiment of the utility model, described noise reduction layer is the resin-cast layer, and noise reduction layer and core limb body are bonding by glue.
In preferred embodiment of the utility model, described noise reduction layer thickness is 0.5-1mm.
In preferred embodiment of the utility model, described stretch-proof layer thickness is 0.1-0.3mm.
In preferred embodiment of the utility model, described screen is ferrite.
In preferred embodiment of the utility model, described insulating cylinder is fastened by two identical semicircular cylinders and forms.
The beneficial effects of the utility model are: the utility model noise reduction demagnetize reactor 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
Fig. 1 is the perspective view of the utility model noise reduction demagnetize reactor one preferred embodiment;
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 utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection range of the present utility model is made more explicit defining.
See also Fig. 1, the utility model embodiment 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, the utility model noise reduction demagnetize reactor 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 embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification 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 utility model.
