Abstract
The high-voltage system has at least one feed line and at least one high-power circuit breaker, the at least one feed line having a longitudinally extended feed line inner conductor and a feed line outer conductor surrounding the feed line inner conductor, and the high-power circuit breaker having a longitudinally extended circuit breaker inner conductor and a circuit breaker outer conductor surrounding the circuit breaker inner conductor in the form of a housing, and the inner conductors and the outer conductors being electrically conductively connected to one another. At least one heat pipe is provided for the purpose of dissipating thermal energy from the circuit breaker inner conductor. The heat pipe interacts with a cooling gas flow extending along the circuit breaker inner conductor.
