Abstract
A power capacitor for high voltage including at least one capacitor element enclosed in a container, use of a gel in such a capacitor, and a method for manufacture of the capacitor. A space is formed between each capacitor element and the container. The power capacitor can handle problems concerning oil leakage in such a capacitor. In the power capacitor the space is filled up by a dielectric fluid including a gelling component. Because a gel is used instead of oil, the risk of oil leakage is eliminated.
Claims24
A power capacitor for high voltage comprising:
- at least one capacitor element enclosed in a container such that a space is formed between each capacitor element and the container;
- and
- an insulating medium arranged inside the container in a form of a dielectric fluid comprising gelling component, which said insulating medium substantially fills said space;
- and
- wherein the container is made of a polymer material.
The use of a gelled dielectric fluid as an insulating medium for insulating one or more capacitor elements in a power capacitor for high voltage, which capacitor elements are arranged in a container of a polymer material.
