Abstract:
1. A high-voltage system comprising: 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 feed line inner conductor and the circuit breaker inner conductor being electrically conductively connected to one another and the feed line outer conductor and the circuit breaker outer conductor being electrically conductively connected to one another, wherein at least one heat pipe is provided in a space between the circuit breaker inner conductor and the circuit breaker outer conductor for the purpose of dissipating thermal energy from at least one of the feed line inner and the circuit breaker inner conductor, and wherein an entire length of the at least one heat pipe is provided in the space between the circuit breaker inner conductor and the circuit breaker outer conductor, wherein at least one production means for flow of cooling gas is provided, by means of which a cooling gas flow, which extends along the longitudinal axis of the circuit breaker inner conductor, can be produced within the circuit breaker outer conductor, and wherein the heat pipe contains a working medium that dissipates the thermal energy by evaporating the working medium in an evaporator section of the heat pipe and condensing the working medium in a condenser section of the heat pipe, and the evaporator section being in close thermal contact with the circuit breaker inner conductor, and the condenser section interacting with the cooling gas flow.
