Embodiment Construction

[0028] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0029] see Figure 1-5 , a four-quadrant low-noise reactor, including a ferrosilicon core 1, epoxy board 2, enamelled aluminum wire 3, temperature sensor 4, nylon cable tie 5 and terminal 6.

[0030] There are three iron-silicon magnetic cores 1, and the iron-silicon magnetic cores 1 are bonded side by side on the epoxy board 2 through glue 8. The enamelled aluminum wire 3 is wound around the outer periphery of the iron-silicon magnetic core 1, and each iron The two ends of the enamelled aluminum wire 3 on the silicon core 1 are connected to the terminal 6 through a high-temperature silicone cable 7, and the iron-silicon core 1 in the middle is c...

Abstract

The invention provides a four-quadrant low-noise electric reactor which comprises three iron-silicon magnetic cores, an epoxy plate, an enameled aluminum wire, a temperature sensor and a wiring terminal, the iron-silicon magnetic cores are bonded on the epoxy plate side by side through an adhesive, the enameled aluminum wire is wound on the peripheries of the iron-silicon magnetic cores, the two ends of the enameled aluminum wire on each iron-silicon magnetic core are connected with wiring terminals through high-temperature silica gel cables, and the iron-silicon magnetic core located in the middle is connected with a temperature sensor through a high-temperature silica gel cable. Due to the fact that air gaps are evenly distributed, magnetostriction is reduced, noise is small, iron loss is small, heat dissipation is easier due to the annular shape, and compared with a silicon steel sheet reactor, the magnetic ring reactor is lighter in weight and more economical and practical in price due to the same inductance value.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a four-quadrant low-noise reactor and a manufacturing method thereof. Background technique [0002] Due to the uneven air gap distribution of conventional silicon steel sheet reactors, the iron loss is large, which will cause local heating, and at the same time cause the reactor itself to be noisy, affecting user experience. And to make a reactor with the same inductance, the overall cost of the silicon steel sheet will be higher and the weight will be heavier. Contents of the invention [0003] Based on this, it is necessary to provide a four-quadrant low-noise reactor and a manufacturing method thereof to solve the problems of high noise and high cost of existing reactors. [0004] A four-quadrant low-noise reactor, including iron-silicon magnetic cores, epoxy boards, enameled aluminum wires, temperature sensors and terminals, the iron-silicon magnetic cores are three, and ...
