Abstract: A cooling apparatus for a medium voltage switchgear includes an evaporator section; a fluid conduit; and a condenser section. The evaporator section surrounds a current carrying contact and is configured such that fluid within the evaporator section can contact an outer surface of the current carrying contact. The evaporator section is fluidly connected to the fluid conduit. At least part of the evaporator section is electrically insulating and is connected to the fluid conduit. The fluid conduit is fluidly connected to the condenser section. In use, a working fluid in the evaporator section is heated to a vapor state, the vapor is transferred by the fluid conduit to the condenser section, and the vapor in the condenser section is condensed to the working fluid. The working fluid is passively returned to the evaporator section.

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.
