Molecular sieve capacitor

Abstract

The invention relates to a molecular sieve capacitor. A thin film body is arranged between an outer aluminum shell and a capacitor element. A lead is arranged in a mandrel in the middle of the capacitor element. An anti-explosion end cover is arranged at the upper end of the outer aluminum shell. The molecular sieve capacitor is characterized in that the edge of the anti-explosion end cover is rolled tightly and sealed along the outer aluminum shell, a welding sheet is arranged at the outer side of the anti-explosion end cover, an anti-explosion sheet is arranged at the inner side of the anti-explosion end cover, and a fixing bridge is arranged between the anti-explosion sheet and the anti-explosion end cover; copper foil is arranged at the lower side of the anti-explosion sheet, one end of a solid rivet and the upper end of the copper foil are in point welding, the other end of the solid rivet penetrates through the fixing bridge and is connected with the anti-explosion end cover, and the inner portion of the outer aluminum shell is filled with molecular sieve mixed oil. The molecular sieve mixed oil is formed by polyisobutene oil, salad oil and molecular sieves in a blended mode according to a mixing mass volume ratio of 5:3:2. According to the molecular sieve capacitor, moisture and air in a thin film can be adsorbed and the pressure resistance of the thin film is improved; when partial self-healing occurs on the thin film, generated gas can be effectively absorbed through the mixed oil, so that the performance of internal components is stable; the service life of the capacitor can be prolonged.

Description

Technical field [0001] The invention involves a molecular sieve capacitor, especially a capacitor that can be used for high -voltage equipment. Background technique [0002] For the safe use of household appliances, aviation equipment and some high -pressure equipment, such as solar inverter equipment, wind.Power generation equipment, water pumps, constant voltage transformers, generators, electric tools, horsepower motors and UPS systems such as the voltage pressure power parts and other equipment.The existing capacitors have a variety of structures, such as the patent application 201120483670 to disclose a metal -based thin film capacitor, including capacitor core, metal shell, leading terminal, upper insulating cover, and lower insulation cover. Among themIn the metal shell, the combination of the insulation cover and the insulation cover to contain the metal shell, wherein the metal polyacrylanic capacitor also includesThe metallic polyacryllatic capacitor described in the im...

Problems solved by technology

[0003] The above-mentioned capacitors can play a good role in starting and running on ordinary electrical equipment, but under high temperature conditions, the stability of its internal components is poor, which is likely to cause poor contact of components and open circuits. The size of the capacitor with the same specification Larger, not suitable for smaller appliances
