1. 10kV distribution insulated circuit fast live line is removed a drainage thread operational method, it is characterized in that:

  • adopt earth potential working method, mainly comprise the following steps;

    1. the application reclosing of stopping using;

    step on that to review and validate circuit to be removed before bar operation zero load and without phase fault and earth fault, and to power scheduling department application this circuit re-switching of stopping using, be confirmed operation electrician in rear bar and start to step on bar operation;

    2. do insulation isolation;

    on the bar of employing earth potential working, electrician swings and may cause the equipment of short circuit or ground connection to do insulation quarantine measures drainage thread in job area on bar;

    3. detachment goddess of lightning line drainage thread;

    on bar, operation electrician hangs up respectively insulation lock hanging bar on the phase conductor of both sides, use insulation Assembly rail that the earth potential working non-bearing connecting clip bus bar part on charged distribution line bus is unscrewed and remove the charged bus of distribution insulated circuit, the drainage thread end of taking apart is hung on insulation lock hanging bar;

    4. the place'"'"'s of taking apart insulation isolation;

    mobile T shape insulated conductor cover, by the isolation of insulating of the nuditing wire of former lap-joint;

    5. take another side phase drainage thread apart;

    repeating step 3. with step 4., remove another side phase drainage thread;

    6. take middle phase drainage thread apart;

    4. 3. repeating step take middle phase drainage thread apart with step;

    7. the drainage thread of taking apart detects and is fixing;

    on bar, operation electrician measures on knocked-down drainage thread and really after no-voltage, removes the earth potential working non-bearing connecting clip on three-phase drainage thread with high voltage electroscope, fixes three-phase drainage thread;

    8. seal is removed;

    on bar, operation electrician returns to ground after one by one insulated isolated device on bar being removed, and recovers this circuit re-switching.
