POWER CAPACITOR AND USE AND METHOD RELATED THERETO

摘要

The present invention relates to a power capacitor for high voltage and comprises at least one capacitor element (2a-2d) enclosed in a container (1). A space is formed between each capacitor element (2a-2d) and the container (1). The object of the invention is to be able to handle problems concerning oil leakage in such a capacitor. According to the invention said space is filled up by a dielectric fluid (10) comprising a gelling component. Because a gel is used instead of oil, the risk of oil leakage is eliminated. The invention also relates to use of a gel in such a capacitor and to a method for manufacture of the invented capacitor.
