Benefits of technology

This patented technology improves upon existing methods used when making aluminium elec trostatic capacitance devices. By changing from single-ply paper to multiple-layers paper weaving designs instead of traditional one-, allowing for greater flexibility while maintaining good performance characteristics such as low leak current density over long periods without losing effectiveness. Additionally, lower temperatures reduce energy consumption compared to older methods like liquid jets, resulting in improved efficiency. Overall, these technical improvements improve the quality control process and prolong their lifespan.

Problems solved by technology

This technical problem addressed in this patents relates to improving the uniform quality of an electric double-layer type cylindrical tantalum elecrosis capacitor when using different materials or configurations due to factors such as wrinkling issues associated with traditional methods involving thin layers of paper.

Abstract

The invention discloses an aluminum electrolytic capacitor based on a multi-layer winding paper design, which comprises a capacitor main body. The capacitor main body is composed of an element and analuminum case, wherein the element is arranged in the aluminum case and comprises no less than three winding layers and guide pins arranged in the winding layers; and the winding layer is formed by winding of an aluminum foil and an electrolytic paper. The mode of the two-layer paper winding design used by the aluminum electrolytic capacitor manufacturing industry is changed to the mode of windingby no less than three paper layers, manufacturing and assembly of aluminum electrolytic capacitors of medium and high voltage series become easier, omission of potential defective products to the market does not need to worry about, painful compensation losses to a client are not caused, winding of more layers/circles and increasement of a total length to make a product with higher voltage withstanding becomes possible, the required withstood voltage of each layer/circle is dispersed, the interlayer withstood voltage drops, after the required each-layer withstood voltage drops, the temperature in the case of charging and discharging drops, the electrolytic paper can be made of a thinner and softer material, and at the time, the impregnated absorption of the electrolyte is more thorough, and the service life of the product is longer.
