Insulating rod assembly, isolating switch and GIS

The invention provides an insulating rod assembly, an isolating switch and a GIS, and belongs to the field of high-voltage switchs.The insulating rod assembly comprises an insulating rod used for being vertically arranged, the upper end of the insulating rod is sleeved with a collecting disc, and the collecting disc is used for receiving metal foreign matter falling from the upper portion to prevent the metal foreign matter from falling to the surface of the insulating rod. And the collecting disc can receive metal foreign matters falling from the upper part, so that the metal foreign matters are prevented from falling on the surface of the insulating rod, a discharge accident can be avoided, and unnecessary loss is reduced. Meanwhile, the outer side face of the insulating rod is provided with the wave-shaped wrinkles, the creepage distance of the insulating rod can be increased, the insulating performance can be improved, discharge accidents are prevented, and meanwhile the wave-shaped wrinkles facilitate di
