| 摘要 |
<p>The invention relates to a method for controlling the heating means (18) of a medium- and/or high-voltage gas-insulated electrical appliance (10) comprising a casing (12), the internal volume of which is filled with a gas containing at least one fluoroketone. In addition, at least one electrical component is arranged inside the casing (12). The method is characterised in that it consists in supplying the heating means (18) when the temperature (T) of the gas is below a threshold temperature defined such that the threshold temperature is above a dew point temperature (TR) of the gas, corresponding to the dew point of the fluoroketone, the difference between the threshold temperature and the dew point temperature being equal to a pre-determined value.</p> |
