A kind of inductance manufacturing method of aluminum wire winding

Abstract

The invention discloses a method for manufacturing an inductor with aluminum wire winding. An inductor is composed of a mounting seat, a magnetic core, a square plate, an enameled aluminum wire, an insulating sleeve and a copper tube. For the specific heat ratio of the material of the inductor, the specific heat ratio of an aluminum wire is larger than that of a copper wire, so that the winding temperature rise of the aluminum wire is low in the condition of the same resistance, current and power-on time so as to prolong the aging process of the insulation and improve the life of the product.For the tensile strength of the wire, the tensile strength or elongation of the aluminum wire is lower than that of the copper wire, but, the aluminum wire can meet the requirement of the product winding for the mechanical properties and the working of the winding is easier so as to save the processing time. For the specific gravity of the wire, the density of the wire is 3.3 times of the densityof aluminum, so that in a condition of the same section and length, the weight of the enameled aluminum wire is 1 / 3 times of the weight of the enameled copper wire so that the enameled aluminum wire can save the cost and can save the resources.

Description

technical field [0001] The invention relates to the technical field of inductance, in particular to a method for manufacturing an inductance of an aluminum wire winding. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. [0003] Usually transformers use enamelled copper wire to wind the coil. Due to the moderate price, low resistivity, excellent tensile strength or elongation, and easy processing, enameled copper wire is widely used in traditional transformer products. However, As the price of copper rises, the advantages of enamelled copper wires become less and less obvious, and the specific heat of copper wires is relatively large, which makes the rate of plastic aging faster and reduces the service life ...
