INSULATION FLUID HEATING APPARATUS AND METHOD
An apparatus (1) for heating an insulation fluid (10) in a medium-voltage or high-voltage switchgear (100) comprises an infrared source (3) which is adapted to emit infrared radiation (4) of at least one wavelength. Thus, at least one vibrational or rotational mode of at least one component (11) of...

Summary: | An apparatus (1) for heating an insulation fluid (10) in a medium-voltage or high-voltage switchgear (100) comprises an infrared source (3) which is adapted to emit infrared radiation (4) of at least one wavelength. Thus, at least one vibrational or rotational mode of at least one component (11) of the insulation fluid (10) is excited by absorption of at least a part of the infrared radiation (4), and condensation of the insulation fluid (10) is efficiently prevented by this direct heating of the insulation fluid (10). A closed loop temperature regulator (5) is used to heat only when required. A circulator (7) in a heating chamber (8) further provides for a mixing of the insulation fluid (10), thus preventing steep temperature gradients. |
