Abstract
Official abstract text for this publication.
An electrical switching system of a circuit breaker, with a first busbar extending in a longitudinal direction, which carries a first contact and a second contact spaced apart therefrom in the longitudinal direction, and which has a first power connection, and with a second busbar extending in the longitudinal direction, which carries a first counterpart contact and a second counterpart contact spaced apart therefrom in the longitudinal direction, and which has a second power connection. The second busbar is mounted so as to be movable in a transverse direction perpendicular to the longitudinal direction, wherein the first busbar partially overlaps the second busbar along the longitudinal direction. In the longitudinal direction, the contacts and the counterpart contacts are arranged between the two power connections in the overlap region.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrical switching system of a circuit breaker, the electrical switching system comprising: a first busbar extending in a longitudinal direction that carries a first contact and a second contact spaced apart from the first contact in the longitudinal direction and a first power connection; and a second busbar extending in the longitudinal direction, which carries a first counterpart contact and a second counterpart contact spaced apart from the first counterpart contact in the longitudinal direction and a second power connection, wherein the second busbar is mounted so as to be movable in a transverse direction substantially perpendicularly to the longitudinal direction, wherein the first busbar partially overlaps the second busbar along the longitudinal direction in an overlap region, and wherein the overlap region is provided between the first and second power connections in the longitudinal direction and the first and second contacts and the first and second counterpart contacts are arranged in the overlap region in the longitudinal direction, such that the first and second contacts and the first and second counterpart contacts are arranged between the first and second power connections in the longitudinal direction. 2. The electrical switching system according to claim 1 , wherein the first contact is aligned with the first counterpart contact and the second contact is aligned with the second counterpart contact in the transverse direction. 3. The electrical switching system according to claim 2 , wherein the first contact is formed by a cylinder and the first counterpart contact is formed by a spherical segment. 4. The electrical switching system according to claim 1 , wherein the first busbar and the second busbar are metal strips. 5. The electrical switching system according to claim 1 , wherein between the first and second counterpart contacts, the second busbar has a projection directed towards the first busbar. 6. The electrical switching system according to claim 1 , wherein the first busbar is spring-loaded in the transverse direction. 7. A circuit breaker comprising: an actuating device; and the electrical switching system according to claim 1 , wherein the second busbar is actuated so as to move in the transverse direction by the actuating device. 8. The electrical switching system according to claim 1 , wherein the first and second contacts and the first and second counterpart contacts are formed of a conductive material.
