1. 35kV overhead distribution replacing linear pole under live state suspension type porcelain vase operational method is characterized in that:

  • comprise the following steps;

    1. the operation circuit re-switching of stopping using;

    2. aerial lift device with insulated arm enters the maintenance place, puts the line space bucket test of going forward side by side of aerial lift device with insulated arm supporting leg, vehicle ground;

    3. use megohmmeter carrying out respectively insulation property along face and detect the insulation clothing in the insulating material in operating apparatus part, safety protective tools, insulated target;

    if insulation resistance greater than 700 megaohms for qualified, otherwise changed;

    The operating personnel dresses insulation clothing, insulation boots, insulating gloves and the insulation safety cap that satisfies the requirement of 35kV line live-line work;

    4. required wire mask, insulator cover, insulated target, cross arm shielding cover and the insulating cord of the operation insulation bucket of aerial lift device with insulated arm of packing into;

    5. in the bucket, the operating personnel operates aerial lift device with insulated arm and enters the setting electric field, according to first electrified body, rear earth electrode principle and from the near to the remote, order from top to bottom, respectively wire, insulator, cross-arm are insulated by wire mask, insulator cover, insulated target and cross arm shielding cover and cover;

    6. in the bucket, operating personnel'"'"'s conducting wire promotes and safeties, hangs and changes the required insulating cord of suspension type porcelain vase;

    7. operating personnel'"'"'s lifting lead wire in the bucket when the wire vertical load shifts and insulator string when being in suitable relaxed state from insulator string, is taken off a bowl head, changes the suspension type porcelain vase, recovers to install and unclamps after the bowl head and remove lifting wire and safeties and insulating cord;

    8. in the bucket operating personnel according to step 5. described orderly release insulation of covering reversed in order cover;

    9. repeating step 5., step 6., step 7. with step 8. to all the other each suspension type porcelain vase mutually change operation;

    10. in the bucket, the operating personnel operates aerial lift device with insulated arm and withdraws from electric field, returns to ground, recovers this circuit re-switching.
