Description

Small-size novel reactor

Technical Field

The utility model belongs to the technical field of the reactor is used, concretely relates to small-size novel reactor.

Background

Reactors, also called inductors, are electrical conductors that, when energized, generate a magnetic field in a certain spatial area occupied by a conductor, so that all electrical conductors capable of carrying current are inductive in the general sense.

However, the inductance of the electrified long straight conductor is small, and the generated magnetic field is not strong, so that the actual reactor is in a mode that a conducting wire is wound into a solenoid, and is called as an air-core reactor; in order to make this solenoid have a larger inductance, a core, called a core reactor, is sometimes inserted into the solenoid.

Reactance is divided into inductive reactance and capacitive reactance, and the more scientific classification is that inductive reactance (inductor) and capacitive reactance (capacitor) are collectively called reactor, however, since the inductor is existed in the past and is called reactor, the capacitor is called reactor now, and the reactor is specially called inductor.

The existing inductor has the defects that on one hand, the winding of the reactor is wound on an annular iron core, a magnetic ring or a framework without pins, the efficiency is low, a plurality of processes are manually completed, and the automatic production is difficult to realize, on the other hand, most of the reactors are in an insulating varnish impregnation mode to improve the insulativity and the noise of the silicon steel sheet, and the risk of poor quality is high due to unstable concentration of paint and poor impregnation process.

Therefore, based on the above problems, the present invention provides a small-sized novel reactor.
