Abstract: An apparatus for heating an insulation fluid in a medium-voltage or high-voltage switchgear comprises an infrared source which is adapted to emit infrared radiation of at least one wavelength. Thus, at least one vibrational or rotational mode of at least one component of the insulation fluid is excited by absorption of at least a part of the infrared radiation, and condensation of the insulation fluid is efficiently prevented by this direct heating of the insulation fluid. A closed loop temperature regulator is used to heat only when required. A circulator in a heating chamber further provides for a mixing of the insulation fluid, thus preventing steep temperature gradients.

Abstract: The present application relates to an apparatus for the generation, transmission, distribution and/or usage of electrical energy, the apparatus including a housing enclosing an insulation space and an electrically conductive part arranged in the insulation space, wherein the insulating space contains a dielectric fluid including carbon dioxide and oxygen. In the apparatus an oxidation catalyst is arranged that includes noble metal particles coated onto or embedded into a carrier and serves for the catalytic oxidation of carbon monoxide to carbon dioxide.
