The invention discloses a polishing device for an SPV-type isolation switch. The polishing device comprises a direct-connected motor, an insulated operating rod, a polishing wheel, a base, an insulated lifting rod and an insulating rope, wherein the tail part of the insulated operating rod is connected with the direct-connected motor; the polishing wheel is fixed at the top part of the insulated operating rod; the base is fixed at the bottom part of the insulated lifting rod; the insulating rope is arranged at the upper part of the insulated lifting rod; and one end of the insulating rope is connected with the insulated operating rod. The polishing device has the advantages that the direct-connected motor is adopted as a power source; fixing is carried out through the base and the insulated lifting rod; position adjustment is carried out on the insulated operating rod by the insulating rope; the polishing wheel is driven to rotate through the insulated operating rod; the polishing wheel rotating at a high speed is in contact with the surface of a switch contact to finish charged polishing operation on the surface of the contact; when the isolation switch contact emits heat and exceeds the temperature is found out, short-time shutdown is applied as quickly as possible; and polishing and trouble clearing can be finished within about ten minutes in general.
Description
technical field [0001] The invention relates to a polishing device for an SPV type isolating switch. Background technique [0002] At present, during the operation of the substation, the SPV type isolating switch contacts used in 110kV ~ 220kV generally use an external imager to inspect the heating of the equipment. After the switch is disconnected and out of service, the dynamic and static contacts of the isolating switch are operated and disconnected, and safety measures are arranged, and the maintenance personnel then set up an insulating platform or a lifting platform for high-altitude operations. However, when the operation department arranges the power outage mode, if the moving contact of the isolating switch is in the power outage state when the switch is disconnected, the operation method is very cumbersome. Sectional busbars are sometimes difficult to implement. Often, in order to arrange for maintenance of the disconnector contacts at intervals, cumbersome switch...
