thirdly, when the temperature of the electric ring main unit body (2) is overhigh, a fan (28) of a moisture absorption part of the moisture absorption part drives sulfur hexafluoride gas in the gas collection hood (1) to flow, the inner sulfur hexafluoride gas in the electric ring main unit body (2) enters the filter box (27) through the gas outlet pipe (4), the gas enters the cooling box (9) of the cooling assembly, an evaporation pipe (81) of the refrigerator (8) cools the gas in the cooling box (9), the cooled gas enters the sleeve (21) through the gas inlet pipe (5), a motor (29) of a reciprocating assembly of the reciprocating gas injection assembly drives a z-shaped shaft (26) to rotate, the z-shaped shaft (26) drives a word returning plate (25) to move up and down, the word returning plate (25) drives an installation ring (24) to move up and down, the installation ring (24) drives a straight pipe (19) of the gas injection assembly to move up and down, the straight pipe (19) drives an L-shaped pipe (7) to move up and down, reciprocating air injection is carried out, and the reciprocating air injection assembly injects the cooled gas to realize omnibearing cooling treatment;
the air pressure sensor 12 is convenient for monitoring the air pressure of the electric ring main unit body (2) and prevents the air pressure in the electric ring main unit body (2) from being smaller than a set value; when the air pressure sensor (12) detects that the air pressure in the electric ring main unit body (2) is lower than a set value, the air is continuously supplied through the air supply pipe (15), and the air supply function is achieved;
and (V) when moisture absorption parts of the moisture absorption components need to replace moisture absorption materials, the first control valve (11) and the second control valve (13) are closed, the adsorption material filling box (14) is taken out, the adsorption material filling box (14) is installed in the filter box (27) after new moisture absorption materials are filled in the adsorption material filling box (14), the moisture absorption materials are convenient to replace, then a sulfur hexafluoride gas pipe is connected with the gas filling pipe (15), the sulfur hexafluoride gas pipe is added into the filter box (27) through the gas filling pipe (15), air in the filter box (27) is discharged from the exhaust pipe (16), the air is prevented from entering the electric ring main unit body (2), and then the first control valve (11) and the second control valve (13) are opened.
