Problems solved by technology

[0003] In order to maintain insulation between the coil and the two sides of the E-type iron core, the existing EI type reactor generally adopts two insulating plates to isolate the two sides respectively, so that the insulating plates need to be fixed on the two sides, and the insulating plates should be installed Fixed jigs or fixtures, which make the assembly work more complicated and not convenient for production

Abstract

The invention discloses a low-noise reactor, which comprises an iron core and a coil. The iron core is an EI-type iron core. The EI-type iron core comprises an E-type iron core and an I-type iron core. The E-type iron core comprises a central leg and two side legs. An internal insulated winding tube is arranged on the central leg. The two side legs are respectively provided with an external insulating plate. By adopting the technical scheme, the low-noise reactor provided by the invention has the advantages that the produced noise can be reduced and the cost is lower.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a low-noise reactor. Background technique [0002] In order to improve the characteristics of the reactor, the existing EI type reactor has a notch on the foot of the E-type iron core, and an insulator is inserted into the notch. When the reactor with the notch passes through the high-order harmonic current, it will generate The magnetostrictive vibration of the iron core caused by the notch, the magnetostrictive vibration of the entire iron core, and the vibration of the coil generate vibration sound in the reactor as noise. [0003] In order to maintain insulation between the coil and the two sides of the E-type iron core, the existing EI type reactor generally adopts two insulating plates to isolate the two sides respectively, so that the insulating plates need to be fixed on the two sides, and the insulating plates should be installed Fixed jigs or fixtures, which make the ...
