Abstract
Description
Technical Field
[0001] This utility model relates to the field of reactor technology, specifically to a foil-wound reactor that saves wiring space. Background Technology
[0002] Reactors, also known as inductors, are widely used in circuits. Due to the electromagnetic induction effect in circuits, they have a certain degree of inductance, which can prevent changes in current. Reactors generally consist of an iron core and windings wound on the iron core. Currently used foil-wound reactors, because the windings are made of copper or aluminum foil, have advantages such as good mechanical strength, strong resistance to short-circuit impact, low high-frequency eddy current loss, and good heat dissipation, and are commonly used in high-power applications.
[0003] In the existing technology, foil-wound reactors are generally led out directly with copper busbars, which are distributed at the beginning and end of each winding. This requires connecting cables and connecting busbars to be arranged on the outside of the reactor during use. The connecting cables and connecting busbars occupy the space around the reactor, which makes it difficult to arrange and install in some compact application scenarios such as electrical cabinets, resulting in certain limitations in use. Utility Model Content

[0006] The reactor provided in this technical solution has multiple windings, each of which is connected to the output terminal block above the iron core via a connecting cable. The output terminal block centrally connects to the electrical equipment, which facilitates centralized wiring and eliminates the need for additional wiring harnesses to connect to the windings, thereby saving the overall size of the reactor and wiring space.
[0007] Preferably, the connecting cable is electrically connected to the winding output terminal via a welding process.
[0008] Preferably, the iron core includes an iron yoke and a plurality of core posts, with the winding posts arranged on each core post.

[0016] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0017] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0018] like Figures 1 to 3 As shown, a specific embodiment of this utility model provides a foil-wound reactor that saves wiring space. This type of reactor can save wiring space during installation and use. Specifically, it includes several iron cores and windings 1 installed on each iron core. Each winding 1 is made of copper foil or aluminum foil. An output terminal block 6 is provided above the iron core. The output terminal block 6 is electrically connected to each winding 1 through a connecting cable 4.
[0019] like Figures 1 to 3As shown, with the above configuration, the reactor provided in this embodiment has multiple sets of iron cores, each set of iron cores is provided with a winding 1. The winding 1 is made of copper foil or aluminum foil, which has the advantages of good mechanical strength, strong resistance to short circuit impact, low high-frequency eddy current loss, and good heat dissipation. Each winding 1 is connected to the output terminal block 6 above the iron core through the connecting cable 4. The output terminal block 6 centrally connects the electrical equipment, which is convenient for centralized wiring. There is no need for additional wire harnesses to be connected to the winding 1 separately, thereby saving the overall volume of the reactor and the wiring space.
[0020] As mentioned above, the connecting cable 4 needs to connect the winding 1 and the output terminal block 6. In order to facilitate the connection, in the actual production process, the connecting cable 4 is electrically connected to the output end of the winding 1 by welding.
[0021] like Figures 1 to 3 As shown, the reactor core provided in this embodiment includes a yoke 3 and several core posts 2, arranged around each core post 2. In order to stably install the output terminal block 6 on the upper end of the core, this embodiment has a mounting bracket 5 fixed on the upper end of the yoke 3, and the output terminal block 6 is fixed on the mounting bracket 5. In this way, the output terminal block 6 can be installed directly above the reactor, which facilitates centralized wiring during use and saves the overall volume of the reactor and wiring space. In practical applications, the output terminal block 6 is fixedly connected to the yoke 3 by bolts or other structures, and is also fixed by screws, which has the advantages of high connection stability and convenient production and assembly. In addition, in order to facilitate fixing the reactor in the installation position, a mounting bracket structure of appropriate size can also be set at the lower end of the reactor, which will not be described in detail here.
[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
