The invention provides an inflating device for high-pressure switch equipment. The inflating device comprises a containing tank for containing a liquid heat conduction medium, wherein an opening from which an air bottle can enter the containing tank so as to be immersed in the liquid heat conduction medium is formed in the top of the containing tank; a heater for heating the liquid heat conduction medium is arranged in the containing tank. When the air bottle is cooled because of inflation of an air chamber of the high-pressure switch equipment, the liquid heat conduction medium can be used for performing heating compensation on the air bottle; the air bottle is immersed in the liquid heat conduction medium, the whole air bottle is relatively uniformly heated, so that the problem of non-uniform partial heating is solved; a medium in the air bottle is relatively stable, so that the inflation efficiency of the whole air bottle when being used for inflating the air chamber of the high-pressure switch equipment can be guaranteed.
Description
technical field [0001] The invention relates to an inflatable device for high-voltage switchgear. Background technique [0002] With the increase of transmission distance and transmission capacity, the development of transmission grid gradually develops in the direction of ultra-high voltage and ultra-high voltage. With the increase of the voltage level, the volume of the gas chamber of the high-voltage switchgear increases rapidly, and the gas consumption increases sharply. Taking the 1100kV high-voltage switchgear as an example, the volume of the GCB gas chamber is more than 20 cubic meters, which requires SF 6 More than 800 kg of gas. Currently, SF 6 The gas is stored and transported by pressurized liquefaction, and the high-voltage switchgear is inflated through the gasification process at the installation site. Thanks to SF 6 Due to the special physical properties of the gas, a large amount of heat needs to be absorbed during the gasification process, which can easi...
