Abstract

The utility model discloses a 800kV extra high voltage direct current line 150kN level soft insulation pull rod comprising an insulation rope. The two ends of the insulation rope respectively form annular sleeves through fixing cards. The insulation rope is made by means of braiding processing of high strength aramid fiber filaments. A protective sleeve sleeves on the insulation rope. According to the utility model, the insulation rope of the utility model is made of the high strength aramid fiber filaments, so that properties of firmness, durability and strong carrying capacity are realized; especially, winding of the soft rope is possible, so that transportation is facilitated; the working time is saved; and the labor intensity of personnel is reduced.

Description

800kV UHVDC Transmission Lines 150kN level soft insulating pull-rod
technical field:
The utility model relates to a kind of power circuit maintenance tool, particularly relates to a kind of 800kV UHVDC Transmission Lines 150kN level soft insulating pull-rod.
background technology:
China's electrical distribution inequality, need long distance powedr transmission, in order to reduce the wastage and to improve power transmission efficiency, adopt more and more ultra high voltage and super UHV transmission, correspondingly the diameter of power transmission line and ground wire is also increasing, its weight is also very large, when replacing linear insulator string under electrification, need to be by lifting wire, the intensity of existing insulation pull-rod is low and structural design is unreasonable, easily occurs that insulation pull-rod damages under large weight pulling force, and hidden danger causes the accident, also exist in addition effort time-consuming, even have the deficiency of personal injury.
utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, intensity is high, bearing capacity is large and the 800kV UHVDC Transmission Lines 150kN level soft insulating pull-rod of long service life.
The technical solution of the utility model is: a kind of 800kV UHVDC Transmission Lines 150kN level soft insulating pull-rod, contain insulating cord, and described insulating cord two ends form annular cover by fixed card respectively, and described insulating cord is processed by the braiding of high strength aramid fiber yarn.
On described insulating cord, be set with protective sleeve.Described annular puts and is provided with pressure sensor, and described pressure sensor is connected with alarm by controller.Described fixed card is hood type structure, clip and connecting bolt, consists of; The end of described insulating cord is equipped with knot, prevents that insulating cord from deviating from from fixed card.
The beneficial effects of the utility model are:
1, the utility model insulating cord is made by Extra High Strength insulated wire (aramid fiber yarn), and durable, bearing capacity is strong, and its two ends form annular cover by fixed card, are convenient to be connected with other hanging mechanisms.
2, the utlity model has the feature, particularly its soft rope such as lightweight, simple in structure, simple to operate can be wound around, and is convenient to transportation, has both saved the activity duration, has reduced again personnel's labour intensity.
3, the utility model is without intermetallic metal joint, is more suitable for live line working that tower window size the is little assurance to insulation effective length, can optimize better extra-high voltage iron tower design.
4, on the utility model insulating cord, be provided with protective jacket, increased its useful life, in addition, the end of insulating cord is provided with knot, prevents from throwing off, and improves the fail safe of using.
5, the utility model insulating cord aramid fiber yarn is through dyeing, dry, weave, drying, and closely, intensity is high in its braiding, and skin parcel one deck aramid line, and intensity is higher.
6, the utility model is reasonable in design, intensity is high, bearing capacity is large and long service life, and it is applied widely, is especially applied to the replacing insulator of 800kV extra high voltage direct current transmission line, is easy to promotion and implementation, has good economic benefit.
accompanying drawing explanation:
Fig. 1 is the structure chart of 800kV UHVDC Transmission Lines 150kN level soft insulating pull-rod.
embodiment:
Embodiment: referring to Fig. 1, in figure, 1-protective jacket, 2-insulating cord, 3-fixed card.
800kV UHVDC Transmission Lines 150kN level soft insulating pull-rod contains insulating cord 2, and wherein: insulating cord 2 two ends form annular cover by fixed card 3 respectively, insulating cord 2 is processed by the braiding of high strength aramid fiber yarn.
On insulating cord 2, be set with protective sleeve 1.Annular puts and is provided with pressure sensor, and pressure sensor is connected with alarm by controller, and pulling force reaches setting alarm, prevents from breaking.
Fixed card 3 is hood type structure, clip and connecting bolt, consists of; The end of insulating cord 2 is equipped with knot, prevents that insulating cord 2 from deviating from from fixed card 3.
The preparation method of above-mentioned insulating cord: the aramid fiber yarn (tubular) that uses twisting 1500D, be made into some shape aramid fiber yarns of rectifying some the rectify dyeing of shape aramid fiber yarn and moistureproof processing the make, aramid fiber yarn is dried, then at the temperature of setting, put aramid fiber yarn into oven for drying, then the shape aramid fiber yarn of rectifying is made into several little tubulars by hand, with cover, knit establishment mechanism and make needed diameter and length, then parcel one deck aramid line tightly outside.Finished product is put in the baking oven that sets temperature and is dried.
Finished product is carried out under work frequency dry flash voltage test, high humility, exchange Leakage Current to be tested and elongation rate test.The percentage elongation of finished product is less than 2%-3%.
The utility model is in ± 800kV extra high voltage direct current transmission line replacing linear insulator string under electrification operation, for replacing mechanical load and the electric insulation intensity of wire that linear insulator chain bears, the insulating tool that carries out the operation of lifting wire.The utility model coordinates with great tonnage hydraulic wire grip, six-multiple conductor line lifter, can effectively solve 1000mm 2large-section lead ± difficult problem of 800kV extra high voltage direct current transmission line replacing linear insulator string under electrification, filled up current domestic 1000mm 2large-section lead ± blank of 800kV extra high voltage direct current transmission line charged for replacement Special-purpose lifting insulating tool.
The above, be only preferred embodiment of the present utility model, not the utility model done to any pro forma restriction, and any simple modification that every foundation technical spirit of the present utility model is done, all still belongs in the scope of technical solutions of the utility model.
