Abstract
Official abstract text for this publication.
A switch chamber for an electrical switch has electrical contacts for switching a current within a switch chamber. The switch chamber has at least one outlet and a swirl chamber arranged at the outlet of the switch chamber. The swirl chamber has a complex geometry that enables a filter function without additional filter elements.
First claim
Opening claim text (preview).
1 . A switch chamber for an electrical switch, the switch chamber comprising: electrical contacts for connecting a current within an opening section; the switch chamber being formed with at least one outlet and a swirl chamber formed at said at least one outlet. 2 . The switch chamber according to claim 1 , wherein said swirl chamber is formed with a gas inlet fluidically connected to said at least one outlet of the switch chamber. 3 . The switch chamber according to claim 1 , wherein said swirl chamber is configured to fulfill a filter function by means of a complex geometry thereof without additional filter elements. 4 . The switch chamber according to claim 1 , wherein said swirl chamber with complex geometry has a shape of a semi-ellipsoid or of a cone. 5 . The switch chamber according to claim 1 , wherein a geometry of said swirl chamber is divided into a swirl zone and lateral calming zones. 6 . The switch chamber according to claim 5 , wherein said calming zones are configured to absorb contaminants. 7 . The switch chamber according to claim 1 , which comprises a gas inlet into said swirl chamber and arranged eccentrically relative to said swirl chamber. 8 . The switch chamber according to claim 1 , which comprises an outlet from said swirl chamber arranged at an end of said swirl zone having a smallest radius. 9 . The switch chamber according to claim 8 , wherein said outlet from said swirl chamber leads directly or indirectly into a pressure release for detecting a triggering of the electrical switch via a pressure increase. 10 . The switch chamber according to claim 1 , wherein said swirl chamber forms a part of the switch chamber. 11 . The switch chamber according to claim 10 , wherein said swirl chamber is formed in a housing wall of the switch chamber. 12 . The switch chamber according to claim 1 , wherein said swirl chamber is a separate component mounted on the switch chamber.
