Description

Technical Field

[0001] The utility model relates to electrical equipment, in particular to a reactor. Background Art

[0002] Reactors are also called inductors. Because of the electromagnetic induction effect in the circuit, they have a certain inductance, which can prevent the change of current. When a conductor is energized, it will generate a magnetic field in a certain space it occupies, so all electrical conductors that can carry current have inductance in a general sense.

[0003] However, the inductance of a long straight conductor with current is small, and the magnetic field generated is not strong. Therefore, the actual reactor is a solenoid with wires wound around it, which is called an air-core reactor. Sometimes, in order to make the solenoid have a larger inductance, an iron core is inserted into the solenoid, which is called an iron-core reactor. The production process of a reactor with wires wound around it in the form of a solenoid includes winding and varnishing. Utility Model Content

[0004] The technical problem solved by the utility model is to simplify the reactor structure.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: a coil-free inductor, comprising three groups of silicon steel sheets, each group of silicon steel sheets is in a U-shape, an insulating sheet is provided between two adjacent groups of silicon steel sheets, and a fixed structure is provided on the periphery of the silicon steel sheets.

[0006] The fixing structure surrounds and fixes all silicon steel sheets, so that the positions of all silicon steel sheets are stable.

[0007] In actual use, the conductor passes through the U-shaped silicon steel sheet, and the current passes through the conductor, generating a magnetic field in the silicon steel sheet, which can prevent the current from changing.

[0008] Compared with a reactor in which a wire is wound into a solenoid form, the reactor of the utility model has no coil, a simple structure and a simple manufacturing process.

[0009] The fixed structure includes a pair of front transverse plates, a pair of rear transverse plates, a left longitudinal plate, and a right longitudinal plate. The pair of front transverse plates and the pair of rear transverse plates are arranged front and back relative to each other. A longitudinal connector is connected between the front transverse plates and the rear transverse plates arranged relatively to each other, and a transverse connector is connected between the left longitudinal plate and the right longitudinal plate. The front transverse plates and the rear transverse plates connected by the longitudinal connector fix the front and rear positions of the silicon steel sheets. The left longitudinal plates and the right longitudinal plates connected by the transverse connector fix the left and right positions of the silicon steel sheets.

[0010] Both ends of the front transverse plate and both ends of the rear transverse plate are provided with positioning protrusions, and the left longitudinal plate and the right longitudinal plate are provided with positioning grooves matched with the positioning protrusions. The positioning protrusions cooperate with the positioning grooves to interlock the left longitudinal plate and the right longitudinal plate with the front transverse plate and the rear transverse plate, and the relative positions of the left longitudinal plate and the right longitudinal plate with the front transverse plate and the rear transverse plate are stable, which is conducive to the stability of the fixed structure.

[0011] The front transverse plate and the rear transverse plate are both bent into an L shape, and the transverse connector is located at the bending of the front transverse plate and the rear transverse plate. The transverse connector limits the front transverse plate and the rear transverse plate while connecting the left longitudinal plate and the right longitudinal plate, which is beneficial to the stability of the fixed structure.

[0012] The insulating sheet creates a gap between two adjacent groups of silicon steel sheets, and the longitudinal connecting piece is inserted into the gap.

[0013] The four edges of the left longitudinal plate are all bent, the upper edge of the left longitudinal plate partially overlaps with the rear edge, the lower edge of the left longitudinal plate partially overlaps with the rear edge, and the overlapping portion is connected by a connector. The four edges of the left longitudinal plate are all bent, which is conducive to improving the connection strength of the left longitudinal plate and avoiding bending of the left longitudinal plate. The overlapping portion is connected by a connector, which can further improve the connection strength of the left longitudinal plate and avoid deformation of the left longitudinal plate.

[0014] The four edges of the right longitudinal plate are all bent, the upper edge of the right longitudinal plate partially overlaps with the rear edge, the lower edge of the right longitudinal plate partially overlaps with the rear edge, the overlapping part is connected by a connector, and the bent upper and lower edges of the right longitudinal plate are triangular. The four edges of the right longitudinal plate are all bent, which is conducive to improving the connection strength of the right longitudinal plate and avoiding bending of the right longitudinal plate. Among them, the upper and lower edges of the triangle are equivalent to reinforcing ribs, which is conducive to improving the compressive and tensile strength of the right longitudinal plate.
