DIELECTRIC FABRICATION METHOD FOR HIGH VOLTAGE CAPACITOR

摘要

A method for fabricating a dielectric of a high voltage capacitor including the steps of: superposing an electrode film on a first plastic film having a first face and a second face formed plane with a predetermined thickness and dielectric constant, and winding them to form a winding element; and assembling the winding element inside a case and infiltrating an insulation oil into the case in a vacuum state. Since the dielectric is fabricated by using only the plastic film, the loss value, the internal pressure characteristic and the degradation characteristic caused due to the capacitor paper can be improved, so that a high pressure capacitor satisfying desired characteristics can be fabricated. In addition, by not using the capacitor paper, the production cost can be reduced.
