when the temperature of the electric ring main unit body (2) is too high, a fan (28) of the moisture absorbing part drives sulfur hexafluoride gas in the gas collecting cover (1) to flow, the 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, the evaporation pipe (81) of the refrigerator (8) cools the gas in the cooling box (9), cooled gas enters the sleeve (21) through the gas inlet pipe (5), a motor (29) of a reciprocating assembly of the reciprocating jet 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 the mounting ring (24) to move up and down, the mounting ring (24) drives a straight pipe (19) of the jet assembly to move up and down, the straight pipe (19) drives the L-shaped pipe (7) to move up and down, the reciprocating jet assembly jets cooled gas, and the full-direction cooling treatment is realized;
the air pressure sensor 12 is convenient for monitoring the air pressure of the electric ring main unit body (2) and avoids that the air pressure in the electric ring main unit body (2) is 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 supplemented through the air adding pipe (15), so that the electric ring main unit has an air supplementing function;
and fifthly, when the moisture absorbing part of the moisture absorbing component needs to be replaced with moisture absorbing materials, the first control valve (11) and the second control valve (13) are closed, the adsorbing material filling box (14) is taken out, the adsorbing material filling box (14) is filled with new moisture absorbing materials and then is arranged in the filter box (27), moisture absorbing materials are convenient to replace, then the sulfur hexafluoride gas pipe is connected with the gas adding pipe (15), the sulfur hexafluoride is added into the filter box (27) through the gas adding 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 the first control valve (11) and the second control valve (13) are opened.
