Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a novel reactor combination structure. Background Art

[0002] The reactor is one of the most critical devices in the power system. Its main function is to limit short-circuit current, compensate reactive power, filter and improve the power quality of the power system. In modern complex power networks, with the continuous growth of power load, the widespread application of power electronic equipment and the increasing requirements for power quality.

[0003] When a short-circuit fault occurs, the short-circuit current may instantly reach a very high value, which will not only cause serious impact and damage to electrical equipment, but may also cause instability in the power system or even large-scale power outages. The inductor can effectively limit the amplitude of the short-circuit current through its inductance characteristics, thereby protecting other electrical equipment from the impact of excessive current and ensuring that the power system can maintain relatively stable operation in the event of a fault.

[0004] The existing reactors on the market are prone to generate a lot of heat after long-term use, and they need to be cooled. The current way to dissipate heat for reactors is to add external heat dissipation devices for auxiliary heat dissipation. This method increases the overall volume of the power module, thereby increasing the processing cost and cannot meet the needs of users. Utility Model Content

[0005] In order to make up for the above shortcomings, the present invention provides a novel reactor combination structure, aiming to improve the problem that the heat dissipation structure used in the reactor in the prior art easily increases its overall volume.

[0007] As a further description of the above technical solution:

[0008] The right end of the aluminum plate bracket on the right side is threadedly connected with a screw, and the left end of the screw passes through the corresponding aluminum plate bracket and is threadedly connected with a nut.

[0010] A plurality of mounting holes are provided at the four corners of the top of the bottom plate.

[0011] As a further description of the above technical solution:

[0013] As a further description of the above technical solution:

[0015] The utility model has the following beneficial effects:

[0016] 1. In the present invention, the heat generated by the flat coil can be dissipated and cooled by the thermally conductive silicone sheet arranged on the bottom plate, thereby increasing the service life of the reactor. The heat dissipation structure is relatively simple and can reduce the overall volume of the power module, thereby reducing processing costs and meeting the needs of users.

[0017] 2. In the present invention, a shell is first placed on the outside of the flat coil and then the first magnetic core and the second magnetic core are assembled by screws.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a novel reactor combination structure, including a bottom plate 1, aluminum plate brackets 2 are fixedly connected to the left and right sides of the bottom plate 1, a silicone sheet 3 is fixedly connected to the top of the bottom plate 1, the right end of the left aluminum plate bracket 2 is fixedly connected to the second magnetic core 6, the left end of the right aluminum plate bracket 2 is fixedly connected to the first magnetic core 4, the adjacent sides of the first magnetic core 4 and the second magnetic core 6 are each provided with a shell 5, the outside of the two shells 5 is provided with the same flat coil 11, the size of the silicone sheet 3 matches the bottom size of the flat coil 11, the right end of the right aluminum plate bracket 2 is threadedly connected to a screw 8, the left end of the screw 8 passes through the corresponding aluminum plate bracket 2 and is threadedly connected to a nut 9;

[0024] Specifically, when assembling the reactor, the flat coil 11 first needs to be carefully placed on the two shells 5, and then the first magnetic core 4 and the second magnetic core 6 are placed on both sides of the shell 5 respectively, and then these components are tightly assembled together using screws 8. Through this design, it can be ensured that the first magnetic core 4 and the second magnetic core 6 meet the necessary safety distance requirements from the flat coil 11, thereby avoiding any potential short circuit or electrical failure. During long-term use, the flat coil 11 in the reactor may generate a large amount of heat. In order to effectively dissipate this heat, the heat generated by the flat coil 11 during operation can be effectively conducted and dissipated through the thermal conductive silicone sheet 3, thereby reducing the temperature of the flat coil 11 to ensure the stable operation of the reactor. This heat dissipation structure is not only simple and practical, but also can effectively reduce the overall volume of the power module, thereby further reducing processing costs.

[0025] Reference Figure 1 and Figure 2 , a plurality of mounting holes 10 are provided at the four corners of the top of the bottom plate 1;

[0026] Specifically, the reactor can be conveniently fixed at a desired installation position through the mounting hole 10 , thereby improving the practicability of the device.

[0027] Reference Figure 2 , the outside of the flat coil 11 is provided with a Nomi paper 7, and the size of the Nomi paper 7 matches the size of the flat coil 11;

[0028] Specifically, the Nomi paper 7 can keep the winding and the iron core as well as different windings insulated, avoiding the occurrence of short-circuit faults, thereby ensuring the normal transmission and conversion of electrical energy.

[0029] Working Principle: The flat coil 11 in the reactor tends to generate a lot of heat after long-term use. At this time, the heat generated by the flat coil 11 can be dissipated and cooled by the thermally conductive silicone sheet 3 provided on the bottom plate 1, thereby extending the service life of the reactor. This heat dissipation structure is relatively simple and can also reduce the overall volume of the power module.

[0030] When assembling the reactor, the flat coil 11 is first put on the two shells 5, and then the first magnetic core 4 and the second magnetic core 6 are placed on both sides of the corresponding shell 5 respectively. Then, these components are assembled together with screws 8. The first magnetic core 4 and the second magnetic core 6 can be completely isolated from the flat coil 11, thereby effectively achieving an insulation effect.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
