At the same time, the controller 22 and the humidity sensor 20, the raindrop sensor 21, the fan 3 and the oil pump 10 are all compatible and electrically connected (this is the prior art, and no further details are given here). The drying mechanism and the lubrication mechanism can be set in two groups according to the actual usage conditions, so as to better dry and lubricate the three-phase isolating switch body 1. When the humidity sensor 20 detects that the humidity in the weather is too heavy, the controller 22 will start the fan 3 and the heating box 7, and the heated air will enter the connecting pipe 5 through the air duct 4, and then be blown to the transmission member 103 and the connection between the rotating porcelain bottle 102 and the transmission member 103 through the air outlet 6, so as to air dry the transmission member 103 and the connection between the transmission member 103 and the rotating porcelain bottle 102, so as to effectively reduce the rust on the three-phase isolating switch body 1.

Through the operation of air drying and lubrication, the rust of the transmission connecting rod pin shaft and the rotating bearing on the three-phase isolating switch body 1 can be effectively reduced, thereby reducing the failure rate of the three-phase isolating switch body 1 and improving the use effect of the three-phase isolating switch body 1.

The lubricating mechanism can add lubricating oil to the transmission member 103 and the connection between the rotating porcelain bottle 102 and the transmission member 103. Through the operation of air drying and lubrication, the rust of the transmission connecting rod pin shaft and the rotating bearing on the three-phase isolating switch body 1 can be effectively reduced, thereby reducing the failure rate of the three-phase isolating switch body 1 and improving the use effect of the three-phase isolating switch body 1.

[0038] The heating box 7 can be used to heat the wind used by the fan 3 to improve the drying efficiency. The filter box 8 can filter impurities and moisture in the air. The mounting shell 2 can be fixed on the placement rack 15 through a fixing mechanism, and it is convenient to remove the mounting shell 2 for maintenance.
