Abstract
The utility model provides a trapezoid zinc thickened high-square-resistance aluminum film. The trapezoid zinc thickened high-square-resistance aluminum film comprises a film and is characterized in that a thickened area plated with a metal element zinc, a trapezoid transition area plated with the metal element zinc, and a high-square-resistance area plated with the metal element aluminum are successively arranged on the film, wherein the thickened area, the trapezoid transition area and the high-square-resistance area form a trapezoid. The trapezoid zinc thickened high-square-resistance aluminum film can be used to manufacture an inverter capacitor, the current impact resistance capability of the capacitor in a circuit is improved, and the overpressure resistance of the film is enhanced, therefore, the trapezoid zinc thickened high-square-resistance aluminum film has quite good application in the production of the inverter capacitor and achieves good effects.
Description
Technical field:
The utility model relates to a kind of trapezoidal zinc thickening high square resistance aluminium film, belongs to field of capacitor manufacture.
Technical background
Along with new forms of energy are constantly developed, China constantly drops into photovoltaic industry and wind power generation, and therefore the related industry relating to is also developed.Existing inversion capacitor adopts common aluminium film to make, and when electric current increases, capacitor is easy to be subject to rush of current, destroys aluminium film and capacitor.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model solves the technical scheme that its technical problem adopts: a kind of trapezoidal zinc thickening high square resistance aluminium film, comprise film, it is characterized in that: above described film, be provided be successively coated with metallic element zinc thickened area, be coated with the trapezoidal transition district of metallic element zinc and be coated with the high square resistance district of metallic element aluminium, described thickened area, trapezoidal transition district and high square resistance district form trapezoidal shape.
The square resistance of described thickened area is 3-6 Ω/.
The square resistance in described trapezoidal transition district is 6-9 Ω/.
The square resistance in described high square resistance district is 40-70 Ω/.
The inversion capacitor that the utility model is made, has improved the resistance to rush of current ability of capacitor at circuit, and film is withstand voltage, and the utility model is well applied in inversion capacitor is produced, and has obtained good effect.
