Abstract
The invention relates to a filter bag for holding filtering material located inside a gas-installed housing of the electrical installation. The filter bag is produced from a fabric that is resistant to high temperatures, which eliminates the need for holding devices protecting the filter bag from hot switching gases to be provided inside the compressed gas housing.
Claims2
A filter bag for the reception of filter material which, within a casing of a compressed-gas-insulated electric switch unit generating a switch gas jet during a switching-off operation, binds decomposition products from the switch gas such that the filter bag includes a temperature-resistant fabric and is arranged in the switch gas jet.
