Description

[Detailed Description of the Invention] The present invention relates to electromagnetic equipment such as transformers and accelerators, and its purpose is to share and integrate capacitors, which are often used in electric circuits, with the electromagnetic equipment to have multiple functions. The aim is to reduce the size, weight, and cost by increasing the size of the device.

Conventionally, each of the capacitor and the electromagnetic device has been constructed into a single component 1. Therefore, the current trend toward reducing the size and weight of these combinations is to reduce the size and weight of each component by improving the performance of each component, and to reduce dead space by improving mounting technology. be.

However, there are limitations when configuring the capacitor and the electromagnetic device separately, and it is not possible to achieve sufficient size and weight reduction.

The present invention consists of a magnetic core constructed by interposing a magnetic material between magnetic thin strips or magnetic thin plates, and a magnetic core formed by winding and laminating the magnetic material in the first order, and 1. It is characterized by having a magnetic thin strip or magnetic thin plate all capacitor electrodes facing the magnetic core, and by sharing the capacitor part with the magnetic core part of the laminated porcelain, it can be used only for electromagnetic equipment. The capacitor function can be obtained by the size and weight of the capacitor, and it has the effect of reducing the size and weight of the combination of the capacitor and electromagnetic equipment.

Embodiments of the present invention will be described below based on FIGS. 1 to 8.

It is attached mechanically and mechanically. 131 t11+ is an exit wire +2), and a material that covers the +51 part is a good material such as polyester adhesive tape, but it is expensive! When heat resistance is required, materials such as glass cloth and aromatic polyamide sheets are used.

Although it is possible to mechanically make the silicon steel plate used as a normal magnetic core material thinner, in the case of a silicon steel plate, it is possible to make the magnetic thin film (]) +44 thinner with a thickness of approximately 0.2 mm. The minimum loss (shown in 111), and it is not possible to lower the iron loss below this. When adding a capacitor function to the magnetic core, the thinner the thickness, the better in order to improve winding and increase the number of responders. In terms of the performance of a capacitor, the smaller the iron loss, the smaller the temperature rise and the more stable the capacitance h1.For this reason, the silicon steel plate mentioned above is not suitable. Materials include amorphous magnetic core materials and high-silicon steel strips produced by ultra-quenching methods such as single roll and double roll methods.The unit thickness of these materials is approximately 10 to 100 microns. It has excellent flexibility and low iron loss characteristics.For example, as an amorphous magnetic core material, its alloy composition is FeAl1"001Fet.

Examples of the dielectric material (7) include thin strips such as carbon fiber, polyethylene terephthalate film, polyimide film, boronutylene film, and polyphenylene oxide film, and the magnetic core is formed between the magnetic thin strips (11 and (4)). The thin strips are sandwiched together and wound together.
