Problems solved by technology

[0002] Most of the capacitors produced in the market are metallized film capacitors, aluminum electrolytic capacitors and other composite dielectric capacitors; most electrodes are made of zinc, aluminum or zinc-aluminum materials; the media are films and paper or impregnated paper; but in high current In addition to high-frequency and ultra-high-frequency applications, currently it is still relying on series connection, parallel connection and increasing the lead-out cross-sectional area or adding a water circulation cooling system; this will undoubtedly increase the volume of the product and consume more materials; in terms of cost, stability, durability Moderate technical parameters and performance are still lacking

Abstract

The invention discloses an oil-immersed copper foil capacitor and a manufacturing technology thereof, and relates to the technical field of capacitors. The oil-immersed copper foil capacitor comprises a core, a copper material lead-out end, an insulating sheath, a sealing plate, oil and a shell, wherein the copper material lead-out end can be welded or adhered to two side polar surfaces of the core according to the area of the lead-out end; the insulating sheath sleeves between the core and the shell to form an insulating band; the sealing plate penetrates through the copper material lead-out end and the shell for sealed combination; the contact part of the copper material lead-out end is welded for sealing, and epoxy filling sealing is executed. The oil-immersed copper foil capacitor is small in size, low in loss, high in heat dissipation property, high in overcurrent and stable in voltage resistance and can bear high frequency and ultrahigh frequency.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to an oil-immersed copper foil capacitor and a manufacturing process thereof. Background technique [0002] Most of the capacitors produced in the market are metallized film capacitors, aluminum electrolytic capacitors and other composite dielectric capacitors; most electrodes are made of zinc, aluminum or zinc-aluminum materials; the media are films and paper or impregnated paper; but in high current In addition to high-frequency and ultra-high-frequency applications, currently it is still relying on series connection, parallel connection and increasing the lead-out cross-sectional area or adding a water circulation cooling system; this will undoubtedly increase the volume of the product and consume more materials; in terms of cost, stability, durability Mild technical parameters and performance are still lacking. Contents of the invention [0003] In view of the deficiencie...
