High-power high-frequency reactor

Abstract

The invention discloses a high-power high-frequency reactor comprising a reactor body, the reactor body is composed of a magnetic core and a coil, the middle of the magnetic core is provided with thecoil, both the coil and the magnetic core are made of copper materials, the reactor body is a shell structure, the inner part of the shell structure is set in a centering type, the shell structure isformed by a block splicing group and ring stacked columns, magnetic path between rings of the block splicing group is independent without other artificial gaps, and the computability of the electromagnetic theory is good. The fixation of rings with glue is not needed, the coil and the ring-shaped magnetic core support each other and fix each other, and the adding of a special fastener for the magnetic core and the coil is not needed. The structure of the high-power high-frequency reactor is a shell structure, the centering type (block splicing group and ring stacked column type) has small magnetic leakage, the number of turns can be reduced in a product with the same inductance, the DC overlap characteristic is good, the amount of copper is reduced, the material cost is low, the product structure and process are simple, the high-power high-frequency reactor is easy to produce, and the labor cost is low.

Description

technical field [0001] The invention relates to a reactor, in particular to a high-power high-frequency reactor. Background technique [0002] A reactor is also called an inductor. When a conductor is energized, it will generate a magnetic field in a certain space it occupies, so all electric conductors that can carry current have inductance in the general sense. However, the inductance of the energized long straight conductor is small, and the magnetic field generated is not strong, so the actual reactor is in the form of a solenoid wound with wires, which is called an air-core reactor; sometimes in order to make the solenoid have a larger inductance, The iron core is inserted into the solenoid, which is called iron core reactor. Reactance is divided into inductive reactance and capacitive reactance. The more scientific classification is that inductors (inductors) and capacitive reactances (capacitors) are collectively referred to as reactors. However, since inductors exis...

Reactance is divided into inductive reactance and capacitive reactance. The more scientific classification is that inductors (inductors) and capacitive reactances (capacitors) are collectively referred to as reactors. However, since inductors existed first in the past and were called reactors, So now what people call a capacitor is a capacitive reactor, and a reactor specifically refers to an inductor, and there are many defects in the existing inductors: block assembly type: multiple block magnetic core splicing and recombination, each Due to the size tolerance of the blocks, there must be many gaps between the blocks when the blocks are assembled, and the calculation of the electromagnetic theory is poor; the blocks must be fixed with glue, the processing time is long, the process is complicated, and the thermal stability is poor; the reactor increases with temperature. High, the noise becomes larger; the product assembly structure is complex, the upper and lower magnetic cores must be fixed with a fixed plate and upper and lower pull rods

Ring stacked column type: multiple annular magnetic core stacked columns, the inner and outer cylinders of the ring are high, and the coil winding and the inner and outer walls of the annular magnetic core are poorly compliant; the single-turn circumference of the coil is long, the amount of copper used is increased, and the material cost is high; the reactor Large DCR, high copper loss, and high temperature; coil winding is difficult and can only be done manually
