A multilayer film capacitor

Abstract

The invention discloses a multilayer film capacitor, which structurally comprises nuts, a positive terminal, ceramic rings, rubber gaskets, a fixed plate, a fixing hole, a capacitor compensation device, bumps, a transmission wire, a control panel and a negative terminal, wherein the negative terminal is welded at the left end of the upper surface of the capacitor compensation device; the positiveterminal is embedded into the right end of the upper surface of the capacitor compensation device; and the ceramic rings are nested on an outer ring of the positive terminal. According to the multilayer film capacitor, through the arrangement of the capacitor compensation device, how long the loss of the capacitor reaches a certain extent to supplement a backup capacitor is calculated according tothe loss of the capacitor per unit time; and through internal transmission of equipment, the backup capacitor is in contact with a main body capacitor and is internally electrically connected with the main body capacitor, the dielectric volume of the capacitor is increased, the capacitance is restored into the original magnitude and a circuit is restored into normal operation, so that the whole capacitor does not need to be replaced, thereby prolonging the service life of the capacitor and ensuring normal operation of the equipment.

Description

technical field [0001] The invention is a multilayer film capacitor, which belongs to the field of capacitors. Background technique [0002] A capacitor is composed of two electrodes and a dielectric material between them. The dielectric material is a dielectric. When it is placed in the electric field between two parallel plates with equal opposite charges, due to polarization, the Polarized charge is generated, so that the charge bound on the plate increases accordingly, and the potential difference between the plates remains unchanged. The metallized film capacitor is also a kind of capacitor. When the current technical public equipment is used, due to the metallized film Capacitors are prone to capacity loss under long-term working conditions and self-healing can lead to capacity reduction, shortening the service life of the capacitor, and capacity reduction will reduce the working efficiency of the circuit, affect the normal use of the circuit, and then affect the overa...
