Description
Technical Field
The utility model relates to a reactor magnetic core technical field specifically is an annular magnetic core for 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 reactors use a toroidal metal strip magnetic core that is wound through a strip and then cut to form an air gap. Therefore, short circuit between strips of the cutting surface can be caused, and great loss can be generated, so that the inventor combines various factors and provides the annular magnetic core for the reactor.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an annular magnetic core for reactor to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides an annular magnetic core for reactor, includes the magnetic core body, and the magnetic core body is cyclic annular, and the magnetic core body forms cyclic annular magnetic core by a plurality of magnetic core block combinations, is provided with the film piece as the magnetic core air gap between the magnetic core block.
As a further aspect of the present invention: the magnetic core blocks are formed by stacking metal sheets to form fan-shaped blocks.
As a further aspect of the present invention: the foil is stamped from a metal strip.
Compared with the prior art, the utility model discloses the beneficial effect of following several aspects has:
the existing reactors use a toroidal metal strip magnetic core that is wound through a strip and then cut to form an air gap. Thus, short circuit between strips on the cutting surface can be caused, and great loss can be generated; the utility model generates metal sheets by stamping, then the metal sheets are stacked into fan-shaped magnetic core blocks, and form an annular magnetic core by splicing, and a thin film sheet is arranged between the magnetic core blocks as a magnetic core air gap; avoid cutting the strip and causing large loss.
