Description
Technical field
The present invention relates to a kind of instrument, more particularly to the big span line live-line work rope fixture of the big discrepancy in elevation.
Background technology
Extra-high voltage alternating current-direct current transmission line of electricity has that transmission capacity is big, power transmission distance is remote, transmission losses is small, saves line corridor
The advantages that, in full preparation, but extra-high voltage is also big just because of transmission power for the construction of extra-high voltage, and steel tower is high, establishes on mountain more
The place in high high mountain, just so, also occur the situations of the big big spans of the discrepancy in elevation on extra high voltage line more.
If worked on the line grounding wire of the big span of the big discrepancy in elevation, operating personnel will go out by the first-class instrument of rope ladder from steel tower
Line, while the installation protection rope on rope ladder head, can retract steel tower by manpower by rope ladder head and operating personnel.Operating personnel takes
Rope ladder head slide 200-300 meters in ground wire, protection rope will extend same length from steel tower end.Due to the influence of rope deadweight
Sag is also easy to produce, while produces resistance downward and to slip opposite direction so that operating personnel can not independently be slided by gravity
Row overhauls place to ground wire.So operating personnel is only advanced by manpower to line of travel, consumes operating personnel's significantly
Muscle power, while add work often, operating efficiency declines to a great extent.Go out ground wire work, lower section circuit does not have a power failure generally.Protection rope
Caused sag is excessive, causes wire and protects rope safe distance reduction, wire easily occurs to protecting the situation restricted and discharged, so as to
Make operating personnel that electric shock accidents occur.
