Description

Technical Field

[0001] The utility model relates to the technical field of reactors, and specifically relates to a conjugate reactor. Background Technique

[0002] A reactor, also called an inductor, is widely used in circuits. Due to the effect of electromagnetic induction in the circuit, there is a certain inductance, which can play a role in preventing current changes. When a conductor is energized, a magnetic field will be generated in a certain space range it occupies. Therefore, all current-carrying conductors have inductance in a general sense. However, the inductance of a straight energized conductor is small, and the generated magnetic field is not strong. Therefore, an actual reactor is formed by winding a wire into a solenoid form, called an air-core reactor; sometimes, in order to make this solenoid have a larger inductance, an iron core is inserted into the solenoid, called an iron-core reactor.

[0003] In the prior art, such as a one-to-two reactor in a Chinese patent, publication number: CN214012702U, realizes the purpose of reducing production costs and reducing the installation space occupied by the reactor by sharing an iron yoke between the upper reactor and the lower reactor. In view of how to improve the performance of this reactor, we propose an improved conjugate reactor. Content of the Utility Model

The lower iron yoke of the upper reactor body is conjugate with the upper iron yoke of the lower reactor body. Both the upper reactor body and the lower reactor body are three-phase reactors. The conjugate reactor further includes a plurality of ventilation components, and the plurality of ventilation components are distributed between the iron column and the coil. The iron column of the upper reactor body is shorter than the iron column of the reactor body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further details the specific embodiments of the present utility model with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice the present utility model. Although the present utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative and do not limit the scope of the present utility model.

[0021] Specific Embodiment 1: Please refer to Figure 1-2A conjugate reactor, comprising: an upper reactor body 1, a lower reactor body 2, two bases 3, a plurality of ventilation members 4, a plurality of clamping members 5, a plurality of support bars 6 and a plurality of fasteners 7. Both the upper reactor body 1 and the lower reactor body 2 are three-phase reactors. The upper reactor body 1 is fixedly arranged on the upper side of the lower reactor body 2 through the clamping members 5 and the fasteners 7. Among them, both the upper reactor body 1 and the lower reactor body 2 include an upper yoke, an iron core column and a lower yoke. The lower yoke of the upper reactor body 1 is conjugately arranged with the upper yoke of the lower reactor body 2. The ventilation members 4 and the support bars 6 are distributed inside the upper reactor body 1 and the lower reactor body 2 to improve the overall heat dissipation performance of the conjugate reactor. The two bases 3 are arranged at the lower end of the lower reactor body 2 to facilitate the fixed installation of the conjugate reactor.

[0022] The upper reactor body 1 further includes an upper coil 11, an upper connection row 12 and an upper outgoing line row 13. The upper coil 11 is wound around the iron core column of the upper reactor body 1. Both the upper connection row 12 and the upper outgoing line row 13 are connected to the upper coil 11, and the upper connection row 12 is located above the upper outgoing line row 13.

[0023] The lower reactor body 2 further includes a lower coil 21, a lower outgoing line row 22 and a lower connection row 23. The lower coil 21 is wound around the iron core column of the lower reactor body 2. Both the lower outgoing line row 22 and the lower connection row 23 are connected to the lower coil 21, and the lower outgoing line row 22 is located above the lower connection row 23. The upper outgoing line row 13 and the lower outgoing line row 22 are fixedly connected through the fasteners 7.

[0024] In this embodiment, both the upper connection row 12 and the lower connection row 23 are equipped with insulators.

[0025] In this embodiment, the iron core column of the upper reactor body 1 is shorter than that of the reactor body 2. The difference in size makes the inductance value of the upper reactor body 1 smaller than that of the reactor body 2. The difference in inductance values can meet the different usage requirements of users for the inductance value of the reactor. The inductance can be adjusted by connecting the upper reactor body 1 and the lower reactor body 2 in series, or the inductance can be output independently. That is, this conjugate reactor also has three working modes: the upper reactor body 1 works alone, the lower reactor body 2 works alone, and the upper reactor body 1 and the lower reactor body 2 work simultaneously.

[0026] In this embodiment, the rated inductance of the upper reactor body 1 is 0.5 mH; the rated inductance of the reactor body 2 is 0.1 mH.

[0027] The ventilation member 4 includes a main board 41 and two sub-boards 41. The two sub-boards 41 are symmetrically arranged at the left and right ends of the main board 41. At the same time, the sub-board 41 is of an L-shaped structure, so that the ventilation member 4 has an open square tube structure; in implementation, the ventilation member 4 is arranged inside the upper reactor body 1 and the lower reactor body 2. Taking the upper reactor body 1 as an example, the main board 41 contacts the upper coil 11 and the two sub-boards 41 contact the iron core of the upper reactor body 1. By reducing the contact area between the upper coil 11 and the iron core of the upper reactor body 1, the internal heat accumulation in the upper reactor body 1 can be reduced. At the same time, the hollow structure of the ventilation member 4 is beneficial to the smooth discharge of heat, further improving the working performance of the conjugate reactor.

[0028] Three U-shaped grooves for fixing are also formed on the base 3, and the three U-shaped grooves are distributed along the length direction of the base 3 body.

[0029] Through this technical solution, by integrally designing two iron core reactors with different inductance values, the different usage requirements of users for the inductance value of the reactor can be met. The inductance can be adjusted by connecting the two reactors in series, or the output inductance can be used independently, improving the convenience of use of this conjugate reactor; in addition, the conjugate reactor also has the advantages of reducing the consumption of iron core, saving costs and reducing the occupied space for installation.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
