The linear charged wire lifting device of the electric transmission line has the advantages that the principle and the structure are simple, manual wire lifting operation is avoided, the labor intensity of people is lowered, meanwhile, the safety of operation is improved, maintaining of electrical transmission equipment in a charged mode is facilitated, and the efficiency is improved.
Description
Technical field
The present invention relates to electric power system live line working equipment, particularly the charged line apparatus of carrying of a kind of transmission line straight line.
Background technology
220 kilovolts of straight line replacing insulator under electrifieds are elemental operation projects in live line working, used use method be that insulation tackle pulley method is changed insulator string, because past 220 kilovolt mostly is single conductor circuit, and wire type is in the majority with LGJ-185 type and LGJ-240 type single conductor.Vertical span with 350 meters, the wire of above-mentioned model calculates, and in the time adopting 3-3 insulation tackle pulley, lifting force is equivalent to the weight of 42-57 kilogram, relatively easy by men hoisting wire.
But, along with the requirement of social economy to power supply reliability, newly-built circuit and old transformation circuit, existing 220 kilovolt wire types are increased, change to LGJ-300 type and LGJ-400 type wire by original LGJ-185 type and LGJ-240 type wire, sub-conductor quantity increases, and changes multiple wire into by original single conductor, has some circuits to adopt the multiple conductor structure of LGJ-300 type.With above-mentioned wire type and structure, the vertical span of getting equally 350 meters calculates, while also adopting 3-3 insulation tackle pulley, lifting force is increased to the weight of 66-133 kilogram, become more and more difficult by men hoisting wire, also increased the danger of operation, therefore, the tackle pulley method lifting lead wire that traditional replacing insulator under electrified adopts has been not suitable with the demand for development of current 220 kilovolts of transmission facility hotline maintenances operation simultaneously.
Summary of the invention
The object of the invention is, in order to improve 220 KV transmission line live line working service abilities, to make existing 220 kilovolts of linear insulator chains more change jobs and can be suitable for, spy provides a kind of transmission line straight line the charged line apparatus of carrying.
The invention provides the charged line apparatus of carrying of a kind of transmission line straight line, it is characterized in that: the charged line apparatus of carrying of described transmission line straight line, comprises leading screw 1, hanging point jig 2, insulated hanging pole 3, suspension hook 4;
Leading screw 1 is the instrument of lifting lead wire; Insulated hanging pole 3 is important connection load parts of lifting lead wire in live line working; Hanging point jig 2 bands are useful on the rectangular channel being clamped on cross arm of tower part, and Open Side Down for rectangular channel.
Described hanging point jig 2 bands are useful on the rectangular channel of clamping cross arm of tower, and Open Side Down.
The number of described suspension hook 4 is 1～3.
Described insulated hanging pole 3 is hard material part.
Described leading screw 1 is ball-screw.
When use, utilize hanging point jig 2 by leading screw 1 and the fixing cross arm of tower of insulated hanging pole 3, suspension rod below suspension hook 4 hooks wire, then tightens up wire weight that leading screw 1 bears insulator string and is transferred to this and carries line apparatus, insulator string is got loose and change.
Advantage of the present invention:
The charged line apparatus of carrying of transmission line straight line of the present invention, theory structure is simple, has avoided the operation of men hoisting wire, reduces people's labour intensity, has increased the fail safe of operation simultaneously, is convenient to transmission facility hotline maintenance, raises the efficiency.
