Problems solved by technology

However, by directly evaporating the oil on the base film, it is easy to cause the edge of the metal in the metallized film to be blurred, resulting in low power loss of the wound capacitor, which affects the performance of the product

Abstract

The invention discloses a manufacturing device for a metalized film for a low power loss capacitor. The device includes a master roll, a safety film oil printing device, an aluminum evaporation deviceand a zinc evaporation device. A base film moves along the surface of the master roll. The safety film oil printing device, the aluminum evaporation device and the zinc evaporation device are arranged surrounding the surface of the master roll and along the movement direction of the base film in sequence. The invention also provides a manufacturing process for the metalized film for the low powerloss capacitor. According to the invention, safety film oil is evaporated onto a copying roll and is then transferred to a relief block pattern of a printing roll through the copying roll. The safetyfilm oil is printed on the base film through the relief block pattern. An oil layer corresponding to a blank portion of the metalized film is formed and the oil layer is uniform. At the same time, the metal edge is clear. Therefore, reduction of medium loss of the capacitor and series connection equivalent resistance is facilitated, fluctuation of capacity of the capacitor is reduced, and productperformance is improved. Moreover, the manufacturing device is simple and reasonable in structure and metal evaporation can be performed selectively based on needs.

Description

technical field [0001] The invention relates to the technical field of film capacitors, and more specifically relates to a manufacturing equipment and a manufacturing process of a metallized film for a low power loss capacitor. Background technique [0002] Metallized film capacitors use polyester film or polypropylene film as the medium, and zinc-aluminum alloy is attached to the surface of the film by vacuum evaporation to form electrodes, and capacitors are formed by non-inductive electrodeless winding or gaskets. Metallized film capacitors have the advantages of high withstand voltage, high insulation resistance, and good impedance frequency characteristics. [0003] There is a metal vapor-deposited film part and a blank part on the metallized film, and the blank part includes a margin part and may also include an isolation strip, wherein the metal edge between the margin part and the metal vapor-deposited film part has a great influence on the performance of the capacit...
