Step 3, on the first transmission rope, make a call to one first Portuguese bowline, one first screw thread master lock is passed to this first Portuguese bowline, this the first screw thread master lock being through on the two clasps on the safety belt of equipotential electrician front simultaneously, one end of one backup protection rope is fixed on two clasps, and the other end is fixed on steel tower cross arm end;
The slow pine second of step 4, ground electrician is transmitted rope declines equipotential electrician, when equipotential electrician drops to while maintaining an equal level with equipotential wire, stops declining, and earth potential electrician swings backup protection rope equipotential electrician is delivered to equipotential wire place;
Step 5, equipotential electrician enter equipotential, accomplish fluently safety belt on wire, untie the backup protection rope on two clasps, untie the first screw thread master lock and transmit being connected of rope with first, carry out live line working;
Step 6, after operation, on the first transmission rope, overlap one the 1 word ring, described the one 8 word ring comprise the first annulus and with integrated the second annulus of the first annulus, described first transmits rope through the first annulus and walks around the second annulus, described the second annulus is fixed by the two clasps on one second screw thread master lock and equipotential electrician front safety belt, the first transmission rope between the one 8 word ring and insulation coaster arranges a steel hook, described steel is hooked on equipotential wire, on the second transmission rope relevant position, overlap one the 28 word ring, described the 28 word ring comprise the 3rd annulus and with integrated the 4th annulus of the 3rd annulus, described second transmits rope through the 3rd annulus and walks around the 4th annulus, described the 4th annulus is fixed by one the 3rd screw thread master lock and equipotential safety belt side clasp,
Step 7, equipotential electrician's both hands are held respectively first of the one 8 upper and lower both sides of word ring and are transmitted rope, by first of slow loose the one 8 word ring downside, transmit rope, drop to ground.
In step 3, also comprise: in the first screw thread master lock, be also installed with one second electrodeless rope sling, described the second electrodeless rope sling is ring junction hook, for equipotential electrician, sole is stretched into this second electrodeless rope sling.
The path length of described the second electrodeless rope sling is 1m.
Described steel hook comprises hook and the steel disc hinged with hook, described hook be provided with a connecting hole, one the 4th screw thread master lock is through in this connecting hole, described first transmits rope is provided with one second Portuguese bowline, described the 4th screw thread master lock is also through on this second Portuguese bowline.
Between step 5 and step 6, also comprise: it is fixing to facilitate service kit to be restricted and given equipotential electrician by transmission that earth potential electrician moves to steel tower cross arm end place by insulation coaster.
Near the hanging point place that described steel tower cross arm end is insulator string.
The invention has the beneficial effects as follows: 1, the present invention only adopts the lightweight parts such as rope and screw thread master lock can realize the equipotential live line working of turnover, in the situation that task is constant, has reduced the use of Work tool, has also improved fail safe simultaneously;
2, utilize one to transmit rope, adopt the mode of " pendulum " that equipotential electrician is sent into equipotential, saved muscle power;
While 3, going out equipotential, utilize cleek, by one, transmit rope and be divided into two sections on knot hook, reach the effect of two ropes, wherein the second transmission rope is used as backup protection, first transmits rope is used for prompt drop, and combination utilizes two " 8 word ring " to complete prompt drop, guarantees safe time efficient;
4, reduce the carrying of Work tool, reduced manpower consumption, saved Financial cost, guaranteed the reasonable utilization of operating personnel's muscle power; Reduce the turnover equipotential time, improved operating efficiency.
