Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a stacked iron core for reactors. Background Art

[0002] Reactors, also called inductors, are widely used in circuits. Because of the electromagnetic induction effect in circuits, they have a certain inductance, which can prevent current changes [4]. When a conductor is energized, it will generate a magnetic field in a certain space it occupies, so all current-carrying conductors have inductance in a general sense. However, the inductance of a long straight conductor is small, and the magnetic field generated is not strong. Therefore, the actual reactor is a wire wound into a solenoid, called an air-core reactor; sometimes, in order to make this solenoid have a larger inductance, an iron core is inserted into the solenoid, which is called an iron-core reactor.

[0003] For example, a reactor core column with publication number CN205248074U includes a plurality of stacked core cakes; the core cakes are formed by stacking a plurality of silicon steel sheets, and the reactor core column is formed by stacking a plurality of core cakes, and the entire column core is solidified into one by resin casting; the reactor core column of the utility model casts a plurality of core cakes constituting the core column with resin as a whole, and solidifies them into shape, and the formed core column is then bonded to the upper and lower iron yokes with resin. By adopting such a process, the noise of the reactor can be reduced by about 10dB.

[0004] The above technical solution has some problems in practical application. The technical solution adopts an integrated solidified iron core. The integrated structure is not convenient during transportation and assembly, and is difficult to repair when a partial fault occurs.

[0005] Therefore, it is necessary to invent a stacked iron core for a reactor to solve the above problems. Utility Model Content
