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 leastone 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. 种用于加热中压或高压开关装置(100)中的绝缘流体(10)的设备(1)包括红外源(3)，其适于发射至少个波长的红外辐射(4)。因此，绝缘流体(10)的至少种成分(11)的至少个振动或旋转模式由红外辐射(4)的至少部分的吸收激发，且绝缘流体(10)的冷凝由绝缘流体(10)的该直接加热有效地防止。闭环温度调节器(5)用于仅在需要时加热。加热室(8)中的循环器(7)还提供绝缘流体(10)的混合，因此防止陡的温度梯度。
