Document Type and Number:
WIPO Patent Application WO/2019/109808
Kind Code:
A1
Abstract:
A highly reliable motor start/intermittent run capacitor, comprising a housing (9, 35), a capacitor core (8) disposed in the housing (9, 35), wherein, the capacitor core (8) is formed by winding two layers of metallized polyester film (81); the thickness of the polyester film (811) of the metallized polyester film (81) is in the range from 2 μm to 4 μm, the sheet resistance in the edge thickening area of the metallization layer (812), which acts as an electrode plate, is in the range from 1Ω/□ to 6Ω/□, the sheet resistance in the active area is in the range from 7Ω/□ to 40Ω/□. The present invention mainly solves the technical problem that the durability test of the existing polyester film start/intermittent run capacitor product is easy to generate short circuit breakdown, short in product life and low in reliability.
