Preferably; The bottom of said second sleeve is provided with the sleeve joint hole that supplies insulating bar to stretch into; Stretch into through insulating bar and to form the specific purpose tool that to win the sheath that shunting switch is provided with behind the sleeve joint hole; Said fit system also can be other modes, as is threaded, and draw-in groove connects and other connected modes of being convenient to process.
Preferably; The sidewall of said insulating bar is provided with at least one first through hole; The sidewall of said projecting shaft is provided with second through hole suitable with insulating bar, through cooperating of first through hole and second through hole, and is fixed on the insulating bar with bolted assurance first sleeve; Convenient for assembly, said fixed form also can be other connected modes.
Preferably; The side walls of said sleeve is provided with the third through-hole suitable with insulating bar, through cooperating of first through hole and third through-hole, and is fixed on the insulating bar with bolted assurance second sleeve; Convenient for assembly, said fixed form also can be other connected modes.
Preferably, said first sleeve lateral wall is provided with adjusting rod, and adjusting rod can conveniently take out the arm of force on the shunting switch.
Preferably, the said second cavity inwall is provided with the skid resistant course that one deck increases frictional force, can take out sheath easily, and guarantees that sheath does not damage.
Preferably, said skid resistant course is a rubber layer, and this skid resistant course also can be the big material of other frictional force, and the utility model has adopted rubber layer.
In sum, the advantage of the utility model is: when case modifies tone shelves, use insulating bar respectively with the instrument of first sleeve and second sleeve combination; Increased safe distance, the equipment that guaranteed can normally use under charged situation, has reduced closing down of 10KV circuit; Dwindled the power failure area greatly, the time amount that has reduced when transferring the files loses, and has improved power supply reliability greatly; Change the mode of removing to regulate shunting switch with hand, also brought economic benefit and deep social benefit.
