Abstract
The invention discloses a simple-root breakage high-altitude connecting method for a 330kVdouble bundled conductor. The high-altitude connecting method is adopted, an operator only needs to use a first electrician carrying pulley and a marline climbing rope ladder to reach an operation position, a conductor clamping device is clamped on a small side breaking head of the conductor, a ground electrician enables the conductor clamping device to be clamped on a big side breaking head of the conductor on the ground, then a conductor card is connected with a twisting mill through a steel wire rope, the twisting mill drags the conductor in a gear to the position parallel to a spacing rod, and the breakage conductor is connected through a first electrician full-tension connecting stripe (FTSMS10008-LGJQ300). Tools and materials are simple and light, convenient to carry, small in working quantity, capable of rapidly repairing and recovering line operation.
Description
Technical field
The invention belongs to the transmission line technical field, relate to a kind of high-altitude connecting method, the single fracture of especially a kind of 330kV double bundle conductor high-altitude connecting method.
Background technology
The 330KV circuit is because the discrepancy in elevation is large between some shaft tower, span is larger, and running environment is abominable, and some circuit is positioned near cement plant, the rubble field, often can suffer stone to collapse line, and lime overstocks on wire, even the accident of generation broken string.During processing since landform, landforms and the shaft tower span is large, drop is large etc. that factor is brought difficulty to work repair wire work and be difficult to carry out.
The single method for breaking of processing double bundle conductor of carrying out at present mainly contains following two kinds:
1, unwrapping wire crimping: the method is first the wire of fracture to be put to ground, then adopts aluminium hydraulic pressed connecting pipe hydraulic pressure, detonation pressure or adopts full tension force connecting strip to twine, and crimping (continuing) operation is comparatively convenient, but such method drawback is more.
2, marcottage: the method seems simple possible, but because weight of equipment is heavy, the work high above the ground difficulty, personal security also can not be guaranteed; Simultaneously, this repairing is single can't be finished, and the injustice of sub-conductor is carried out and may be caused in two people docking.
Summary of the invention
The object of the invention is to overcome the shortcoming of above-mentioned prior art, the single fracture of a kind of 330kV double bundle conductor high-altitude connecting method is provided, the mode that continues in the high-altitude that the method adopts, its method of operation is simple, avoid using large-scale implement, and only need the one man operation to carry out, can improve operating efficiency and personnel's personal safety.
The objective of the invention is to solve by the following technical programs:
The single fracture of this 330kV double bundle conductor high-altitude connecting method may further comprise the steps:
1) makes the first electrician carry coaster and marline and climb rope ladder and arrive operation place, the first lead clamping device is snapped on the small size side broken end of wire, and coaster is connected to the end of the first lead clamping device, and steel wire rope is contained on the coaster;
2) the second electrician snaps into the second lead clamping device on the wire large size side broken end on ground, then by the steel wire rope two ends the second wire card is connected with ground strand grinding machine, to the conductor spacer parallel position, the first electrician continues to the fracture wire with full tension force connecting strip with the moving shelves of strand grain inside conductor.
Further, in the step 1), described the first electrician is the first lead clamping device on the small size side broken end of distance 170cm place card.
Further, above-mentioned steps 1) in, described steel wire penetrating coaster, and make the steel wire rope two ends stretch to ground, be convenient to ground the second electrician and connect strand grinding machine and the second wire card.
The present invention has following beneficial effect:
1, method of operation of the present invention is simple, has promoted operating efficiency, avoids using large-scale implement, and the one man operation can carry out, and has improved operating efficiency and personnel's personal safety.
2, practical, be suitable for the transmission line of 330kV and above, it is large particularly to have solved span, and the large large operating environment problem of task difficulty that waits of the discrepancy in elevation has improved the operating efficiency of processing the single fracture of bundle conductor.

Embodiment
The single fracture of 330kV double bundle conductor of the present invention high-altitude connecting method specifically may further comprise the steps:
1) makes the first electrician carry coaster and marline and climb rope ladder and arrive operation place, the first lead clamping device is snapped on the small size side broken end of wire, and coaster is connected to the end of the first lead clamping device, and steel wire rope is contained on the coaster; Described the first electrician is the first lead clamping device on the small size side broken end of distance 170cm place card.Described steel wire penetrating coaster, and make the steel wire rope two ends stretch to ground, be convenient to ground the second electrician and connect strand grinding machine and the second wire card.
2) the second electrician snaps into the second lead clamping device on the wire large size side broken end on ground, then by the steel wire rope two ends the second wire card is connected with ground strand grinding machine;
3) spur the shelves inside conductor to the conductor spacer parallel position with the strand grinding machine, the first electrician continues to the fracture wire with full tension force connecting strip.
Below in conjunction with drawings and Examples the present invention is done and to describe in further detail:
Embodiment
1, at first reconnoitred the scene, found to land by large size side broken end, small size side is suspended in the air.Wire fracture schematic diagram such as Fig. 1.
2, the staff hangs up properly and by the ground electrician rope ladder is pulled to A place (as shown in Figure 1) after rope ladder checks the snap close locking on the tower, the first electrician (carrying marline and coaster) climbs rope ladder arrival work place, the ground electrician transmits the first lead clamping device and (adopts aluminum alloy wire clamp LK30-300, rated load 30KN, maximum open 28mm, deadweight 4kg/m) with coaster (band steel wire rope), the first electrician blocks fixing-line device at distance broken end 170cm place and it is connected reliably by Fig. 2 with coaster (band steel wire rope).The second electrician snaps into the second lead clamping device on the wire large size side broken end on ground, then by the steel wire rope two ends the second wire card is connected with ground strand grinding machine;
3, check whether each tie point is reliable, determine to start the strand grinding machine after reliable, slowly pack up two broken ends by the pulling force of steel wire rope, parallel to each other to sub-conductor.Whether the staff makes mutual balance between sub-conductor along proofreading and correct the broken end position to the broken end place on the rope ladder, makes to twine connecting strip preparation.As shown in Figure 3.
4, adopt full tension force connecting strip to continue.
In sum, method continues in the high-altitude that the present invention adopts, only need the first electrician carries coaster, marline is climbed rope ladder and arrived operation place, lead clamping device is snapped on the small size side broken end of wire, the ground electrician snaps into lead clamping device on the wire large size side broken end on ground, then by steel wire rope the wire card is connected with the strand grinding machine, to the conductor spacer parallel position, the first electrician is with full tension force connecting strip (FTSMS10008-LGJQ300) wire that ruptures is continued with the moving shelves of strand grain inside conductor.Instrument, material are simply light, and be easy to carry, and workload is little, can repair fast, recovers the circuit operation.
