A flattening device for processing winding cores of film capacitors to prevent inward wrinkling

technical field

Background technique

Film capacitors, also known as plastic film capacitors, use plastic films as dielectrics. Film capacitors have many excellent characteristics, so they are capacitors with excellent performance. Its main properties are as follows: non-polarity, high insulation resistance, frequency characteristics Excellent, and the dielectric loss is very small, metallized film capacitors are widely used in electronics, communications, electric power and other fields because of their high insulation resistance, small capacitance loss, reliable, safe and explosion-proof performance. Metallized film is the main material for making metallized film capacitors. The base material of this material is an organic film such as polyester, polypropylene, etc., and the metal is plated on the dielectric base material by vacuum coating. The capacitor is wound by two or more metallized films and plain films. The metal plating layer of the metallized film is very thin and is very easy to oxidize. If there are wrinkles during the manufacturing process, the wrinkles will contain air or moisture , then the metal plating here is prone to ionization or oxidation, thereby reducing the characteristics of the capacitor, the capacitor capacity will be reduced attenuation or failure, the inner film is not flattened, resulting in an increase in ESR, and the internal voids lead to gold spray penetration, causing a short circuit. Especially for capacitors used in DC support applications such as new energy vehicles, electrified locomotives, and solar power generation, if the capacitor fails, it will bring huge losses.
