Mounting of splitter plates in the switch pole of a circuit breaker

摘要

An embodiment of the invention relates to a switch pole of a circuit breaker having two pole shells between which are disposed, in the assembled state, at least one switching contact, current-carrying elements and an arc quenching device having an arc runner plate and at least one splitter plate delimiting an arc chute, wherein at least one slot for accommodating the splitter and/or arc runner plate is provided between the pole shells. In at least one embodiment, there is provided inside between the pole shells a functional component having a least one slot spaced apart from the pole shells which is used to accommodate the at least one splitter and/or arc runner plate.

主权项

1. A switch pole of a circuit breaker, comprising:
two pole shells including an upper pole shell and a lower pole shell, at least one switching contact between the two pole shells when the two pole shells are in an assembled state, current-carrying elements, an arc quenching device including an arc runner plate and at least one splitter plate delimiting an arc chute, at least one first slot for accommodating at least one of the at least one splitter plate and the arc runner plate is provided between the pole shells, and a functional component between the two pole shells, the functional component including at least one second slot spaced apart from the at least one first slot such that the at least one second slot is i) parallel to and aligned with the at least one first slot, and ii) located between the two pole shells at a center portion of the switch pole such that the at least one second slot is usable in cooperation with the at least one first slot to accommodate the at least one of the at least one splitter and the arc runner plate.
