Abstract
The utility model relates to the field of wire protection fittings of a power transmission line, in particular to an indirect live wire repair clamp of the power transmission line. The indirect live wire repair clamp comprises a static contact, moving contacts, and a bolt, wherein the two moving contacts are distributed in the C-shaped static contact with the length of 150 to 250 mm; the moving contacts are connected with the end of the bolt; and a nut connected with the bolt is arranged on the bottom of the C-shaped static contact. The static contact is made of aluminum alloy material, and alloy sands are disposed on the inner surface of the static contact. An arc-shaped groove is formed on each moving contact. The indirect live wire repair clamp has the advantages that the high-strength alloy sands on the inner layer of the hook-shaped static contact can improve the friction force and the contact area to ensure the clamp fixation and prevent looseness; the indirect live wire repair clamp adopting the indirect method is not in contact with the wire so as to mount the repair wire in a suspension manner. In addition, the indirect live wire repair clamp is not restricted by the power failure time, the operation environment, the operators and the tools, and has the advantages of simple structure, wide application range, and convenient and quick operation.
Description
Technical field
The utility model relates to transmission line wire protection gold utensil field, relates in particular to a kind of transmission line indirect method live wire and repairs wire clamp.
Background technology
Transmission line galloping is more frequent, causes lead damage more, and employing splicing sleeve, preformed armor rods or the wiring of generally repairing lead twine method, all needs to have a power failure or equipotential is charged carries out.When the lead major injury surpasses " overhead transmission line maintenance procedure " setting, constitute urgent or significant deficiency, must take immediately to have a power failure and continue; And the lead that satisfies equipotential live line working condition generally damages, can directly repair, but influenced by the power supply reliability index, transmission line has a power failure difficult, equipotential live line working air gap is little, do not satisfy the requirement of live line working, the damage of most of lead can not in time be repaired, and therefore repairs the general damage of lead and be always the difficult problem in the transmission line operation maintenance.
Summary of the invention
The purpose of this utility model provides a kind of transmission line indirect method live wire and repairs wire clamp, is not subjected to interruption duration, operating environment restriction to repair lead fast and generally damage.
For achieving the above object, the utility model is achieved through the following technical solutions:
Transmission line indirect method live wire is repaired wire clamp, it is characterized in that, comprise static contact, movable contact spring, bolt, two movable contact springs distribute in the C shape static contact of long 150～250mm, movable contact spring is connected with the bolt end, is arranged on C shape static contact bottom with bolted nut.
Described static contact is an aluminum alloy materials, and inner surface is provided with alloy sand.
Described movable contact spring is provided with deep-slotted chip breaker.
Compared with prior art, the beneficial effects of the utility model are: 1) hook-shaped static contact internal layer is lined with high-strength alloy sand, increases frictional force and contact area, guarantees that wire clamp is fastening, prevents to become flexible; 2) adopt the not directly contact wire of indirect charged method, suspension type is installed and is repaired lead; 3) be not subjected to interruption duration, operating environment, operating personnel, Work tool to use restriction, simple in structure, applied widely, convenient to operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the end view of Fig. 1.
Among the figure: 1-static contact 2-movable contact spring 3-bolt 4-nut 5-alloy sand 6-deep-slotted chip breaker
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
See Fig. 1, Fig. 2, transmission line indirect method live wire is repaired wire clamp, comprise static contact 1, movable contact spring 2, bolt 3, two movable contact springs 2 of distribution in the C shape static contact 1 of long 150～250mm, movable contact spring 2 is connected with bolt 3 ends, and the nut 4 that is connected with bolt 3 is arranged on C shape static contact 1 bottom.Static contact 1 is generally the aluminum alloy materials of high strength, high conduction performance, with repair wire type, material is consistent, its inner surface is provided with alloy sand 5.Movable contact spring 2 upper surfaces are provided with deep-slotted chip breaker 6, make things convenient for the clamping lead, prevent slippage.
The utility model mainly adapts in transmission line common-tower double-return or the many loop lines circuit, and the C shape hook formation by wire clamp is lodge lead damage location very easily, the loose lead of fastening damage location, increases contact area, thereby realizes handling lead damage purpose.When splicing sleeve, preformed armor rods or wiring winding method repairing lead can't carry out routinely, adopt methods such as high empty wagons, insulated flexible ladder, operating personnel (people) are delivered in the Safe Distance for Live Working scope, the coordinated insulation action bars, directly with this device lodge lead damage location, clamp nut 4 is finished repairing.
The utility model in use is noted that:
1, looks into lead material and sectional area before the installation, selected suitable repairing wire clamp.
2, with high empty wagons or suspension rope ladder operating personnel are delivered to home.
3, in wire clamp, coat conductive paste, suspension clamp on insulating bar, and pass to operating personnel.
4, operating personnel aim at the lead damage location, hang up wire clamp, and it is tight to adjust wire-bonds, rotates fastening bolt respectively, promote movable contact spring and press close to lead, in the precession, should note adjusting movable contact spring, keep movable contact spring closely to contact with lead, until screwing at last.
