Abstract: A cooling apparatus for a medium voltage or high voltage switchgear includes an evaporator, a fluid conduit, and a condenser. The evaporator is configured to surround at least part of a current carrying contact. The fluid conduit fluidly connects the evaporator to the condenser. A section of the fluid conduit is formed within the evaporator and is electrically insulating and is configured such that fluid can contact an outer surface of the current carrying contact. The cooling apparatus is configured such that in use a working fluid in the evaporator is heated to a vapour state, and the vapour is transferred by the fluid conduit to the condenser. The vapour in the condenser is condensed to the working fluid. The condensed working fluid is passively returned via the fluid conduit to the evaporator.

Abstract: A cooling system for a medium voltage switchgear includes a conductor, a fluid conduit, and an insulator, wherein, the conductor extends in a longitudinal axis, wherein, the conductor is configured to carry electrical current in the longitudinal axis direction, wherein a first part of the fluid conduit is located around an outer surface of the conductor and extends around the longitudinal axis, wherein, a second part of the fluid conduit is connected to the first part of the fluid conduit and extends substantially perpendicularly to the longitudinal axis, wherein the insulator is located around the conductor at the position of the fluid conduit and covers the first part of the fluid conduit, and wherein the cooling system is configured such that a fluid can flow into the second part of the fluid conduit and from the second part of the fluid conduit into the first part of the fluid conduit.
