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 [0001] The invention relates to the field of reactors, in particular to a noise reduction and magnetic reduction reactor. Background technique [0002] With the development of the economy, the application of reactors in various fields has become increasingly widespread. Reactors have the functions of filtering, rectifying, and protecting circuits, and can maintain the normal and stable operation of the circuit. [0003] Existing core reactors generally consist of core columns and coils. However, existing iron-core reactors generally have problems such as large noise, large magnetic resistance, and large calorific value, and their safety is poor. Contents of the invention [0004] The technical problem mainly solved by the invention is to provide a noise-reducing and magnetic-reducing reactor with simple structure, high stability, safety and reliability, which can reduce noise, reduce magnetic permeability and enhance anti-saturation performance.
