Abstract
A generator switch including an encapsulation lying at ground potential and an electrical conductor arranged in an insulated fashion inside the encapsulation and at high-voltage potential, as well as a gravity-driven cooling device having an evaporator and a condenser arranged above the evaporator and a coolant. The cooling device is formed as a closed loop-type coolant circuit. During operation of the generator switch, a level of the liquid coolant in the line system in a static cooling device is at least as high as the upper end of the insulating section in the insulator.
