Abstract
An electrical film capacitor in which a pair of metal film electrodes and a porous layer are wound into an assembly, and in which the porous layer serves to wick a liquid dielectric into the wound assembly. The liquid dielectric is an adipic acid ester such as di-isononyl adipate. Mono-isopropyl biphenyl can be added as well.
Claims19
An electrical film capacitor comprising first and second film electrodes, a porous layer, and a liquid dielectric wicked along the extent of the porous layer, said first and second electrodes and porous layer being wound into a wound assembly, and said liquid dielectric consisting essentially of an adipic acid ester, alone or in combination with a biphenyl.
An electrical film capacitor, comprising
- a first film electrode;
- a second film electrode extending generally parallel to and electrically isolated and spaced from said first film electrode;
- a porous layer extending generally parallel to said first and second film electrodes
- said first film electrode and said porous together comprising a metallized paper layer;
- a liquid dielectric wicked along the extent of the porous layer, said liquid dielectric comprising an adipic acid ester;
- said first and second film electrodes being wound into a wound assembly;
- within the wound assembly, said porous layer being positioned between portions of said first and second film electrode;
- a housing surrounding said wound assembly, and retaining said liquid dielectric;
- and
- electrical conductors providing an electrical connection between each of said first and second film electrodes and the exterior of said housing.
