More Information
Summary:In order to dissipate heat losses from the inner conductor ( 21 ), the circuit breaker ( 20 ) having an elongated inner conductor ( 21 ) and an outer conductor ( 22 ) which surrounds the inner conductor ( 21 ) like a housing has at least one heat pipe ( 1 ) which extends from the inner conductor ( 21 ) to the outer conductor ( 22 ) and has an insulating hollow body ( 5 ) in order to form an electrical insulating gap ( 7 ). The heat pipe ( 1 ) advantageously has a flexibly deformable section ( 9 ). The heat pipe ( 1 ) can run in a supporting insulator ( 24 ) which supports the inner conductor ( 21 ). In addition to a working medium, the heat pipe ( 1 ) advantageously also contains an auxiliary gas which results in an enhanced dielectric strength at low temperatures.
