Nonflammable and disaster prevention type capacitor

Abstract

In a nonflammable and disaster prevention type capacitor, the sealing property of the capacitor container is increased, a plurality of capacitor elements are collected, is accommodated in the container, and its inside is vacuum deaerated, the perfluorocarbon liquid deaerated by a deaeration apparatus is filled, and a capacitor which maintains an amount of residual air in the perfluorocarbon liquid to be not larger than 5%, is formed. A fluoride liquid to be filled in the container, consisting of a connection of carbon, fluorine and oxygen, and which includes per fluoropolyether by not smaller than 90% and whose boiling point is not lower than 120° C. and not higher than 270° C., and whose dynamic viscosity at 25° C. is from 0.9 mm2/s to not larger than 14 mm2/s, is impregnated into the capacitor element. An absolute pressure in the container is not smaller than 120 kPa and not larger than 300 kPa.
