Background
As a basic electronic component, a capacitor is mainly used for storing electric energy and holding electric charges in the form of an electric field in a circuit, and the basic structure of the capacitor is composed of two conductive plates, which are separated by a layer of non-conductive insulating medium. For the metallized film capacitor commonly used in industry, the electrical energy is stored by the metallized safety film wound inside, the metallized safety film is generally made by plating a layer of low melting point metal such as zinc and aluminum on the surface of a plastic film with high dielectric constant and good insulating property by a vacuum plating machine, and the safety of the metallized safety film is mainly ensured by the self-healing function of the metallized safety film.
The self-healing function mainly refers to that when an insulating medium is defective and breaks down under the condition of overvoltage, joule heat generated by the insulating medium is enough to melt and evaporate a metallization layer around a breakdown point instantaneously, so that a metal-free insulating isolation region is formed around the breakdown area, and the insulating property of the dielectric layer is recovered, namely the self-healing function.
When the metallized safety film which completes the coating process is transported or stored, the metallized layer is damaged due to the fact that the metallized layer is thinner, contact oxidation with air or water and collision in the transferring process are carried out, the self-healing performance of the metallized safety film is affected, and the service life of a metallized film capacitor processed later is short and the safety is low.
