3. phase drainage thread in installing: drainage thread loads in the drainage thread installation portion (11) of the wire clip body (1) of non-bearing connecting clip by earth potential working electrician on electric pole; Cover drainage thread pressing plate (2) and to be bolted assembly (3) fastening to clamp drainage thread;
4. non-bearing connecting clip is lifted: earth potential working electrician holds on the insulating case (93) of insulating bar, is enclosed within the pedestal (51) of drive screw (5) by the two ends of the socket pin (96) of insulating bar; Near non-bearing connecting clip upwards delivery to the bus of overhead distribution;
5. non-bearing connecting clip hangs up distribution line bus: earth potential working electrician is lifted after near non-bearing connecting clip to bus by insulating bar, the wire clip body (1) of non-bearing connecting clip is moved to bus, bus is entered after between the bus holding portion (14) of wire clip body (1) and the fastening main part (41) of bus bar part (4), slightly toward under pull insulating bar, bus is contacted with the bus holding portion (14) of wire clip body (1);
6. non-bearing connecting clip is fixedly connected with distribution line bus: the afterburning handle (94) on rotating insulated action bars, insulating bar drives drive screw (5) servo rotary of non-bearing connecting clip, under the reverse drive of drive screw (5) spiral, bus pressing plate (4) moves upward clamping bus, and non-bearing connecting clip is fixedly suspended on the bus of distribution line;
7. repeat step 3. to step 6., the drainage thread of all the other two-phases is installed;
8. earth potential working electrician draws near progressively to remove and exists because drainage thread swings the insulation quarantine measures caused on the equipment of short circuit or ground connection hidden danger;
The construction method of charged dismounting non-bearing connecting clip, comprises the following steps:
1. circuit to be taken apart is reviewed and validate before operation zero load and without phase fault and earth fault;
2. earth potential working electrician causes the equipment of short circuit or ground connection hidden danger progressively to take the quarantine measures that insulate from the near to the remote to existing in job area because drainage thread swings on electric pole;
3. earth potential working electrician uses insulation Assembly rail to be unscrewed by the bus bar part (4) of the non-bearing connecting clip on the charged middle phase bus in distribution line;
4. lift non-bearing connecting clip, non-bearing connecting clip is removed the charged bus of distribution line;
5. repeat step 3. with step 4., the non-bearing connecting clip in all the other two-phases is removed respectively the charged bus of distribution line;
6. the drainage thread on non-bearing connecting clip is taken apart by earth potential working electrician;
7. draw near progressively to remove and exist because drainage thread swings the insulation quarantine measures caused on the equipment of short circuit or ground connection hidden danger.
