WIPO Patent Application WO/2018/214012
Kind Code:
A1
Abstract:
A circuit breaker (10) comprises: a longitudinally extending inner conductor (20) and an outer conductor (30) surrounding the inner conductor (20) in a housing-like manner, which have a potential difference with respect to one another in operation, a heat sink (35) comprising cooling fins and being electrically conductively connected to the inner conductor (20) for dissipating a thermal load of the inner conductor (20), and an electrically conductive shield element (40) for reducing field peaks, which is mounted on a side of the heat sink (35) facing the outer conductor (30) and surrounds the heat sink (35) in an umbrella-like manner.
