Description
Technical field
The utility model belongs to the special mould clamp technical field that the double sheets of direct current duplex hang linear insulator chain, and in particular to
The double sheets of ± 500kV duplexs hang V-type replacing insulator string bent plate fixture.
Background technology
Yunnan Power System is with ± 500kV the DC power transmission lines that put into operation at present, DC line have wire weight is big, span is big,
The features such as load is big causes gold utensil, insulator tonnage big, and assembly type is different, and conventional AC live working tools are
It cannot meet the requirements.In ± 500kV DC power transmission lines, the double sheets of electrified replacing linear tower duplex hang V-type composite insulator
It goes here and there in work, is still completed so far without corresponding operational method, relevant supporting operation Work tool is not also researched and developed, profession
Fixture also without research and development, leads to the maintenance of such connection mode can only be carried out using power failure mode, affects confession to a certain extent
Electric reliability.
Utility model content
In view of the above-mentioned problems of the prior art, the utility model does not need to have a power failure, maintenance quickly for replace ±
The double sheets of rich direct current duplex hang the bent plate fixture of linear insulator chain to 500kV forever.
Its technical solution is：
The double sheets of ± 500kV duplexs hang V-type replacing insulator string bent plate fixture, including connecting lever, screw connection vertical core, spiral shell
Bolt, triangle yoke plate；
The connecting lever is made of upper connecting lever and lower connecting lever, and 120 degree of angles, upper connecting lever are formed between the upper connecting lever and lower connecting lever
On offer connecting hole, screw connection vertical core is offered on the lower connecting lever, upper connecting lever is bolted with triangle yoke plate,
The bolt is pierced by the connecting hole setting on connecting lever.
Further, rectangular through-hole is provided on the upper connecting lever, the triangle yoke plate is clipped in the rectangular through-hole of connecting lever.
Further, the triangle yoke plate cross section is isosceles triangle, offers and applies at the center of triangle yoke plate base
Work hole, the bolt pass through the construction hole of connecting hole and triangle yoke plate on upper connecting lever to connect upper connecting lever and triangle yoke plate
It connects.
Advantageous effect：
When hanging V-type replacing insulator string bent plate fixture using the double sheets of ± 500kV duplexs provided by the utility model, it will lead
The triangle yoke plate that line is surveyed is clipped in the rectangular through-hole of connecting lever, and connecting hole and triangle on upper connecting lever are vertically passed through using bolt
Upper connecting lever and triangle yoke plate is fixed in the construction hole of shape yoke plate.The screw for connecting the stick that is pulled is passed through into screw connecting hole,
Tower head side be pulled stick be connected to be fixed on tower head construction hole on connector.During the reversed stress of lower connecting lever, connection bolt resists three
Angular yoke plate side.In operation process, operating personnel can make lower connecting lever stress by tightening screw, upper connecting lever rectangular through-hole
Bottom resists triangle yoke plate side, and insulator chain is made not stress, and quickly the bulb of insulator is taken out from bowl head, solves existing
There is connection mode livewire work mode cannot be used to replace the problem of insulator, improve power supply reliability.Structure letter of the present invention
It is single light and handy, simple installation.
Description of the drawings
Fig. 1 is the utility model structural front view；
Fig. 2 is the utility model structure top view；Wherein, connecting lever, 3- screws connection vertical core, 4- spiral shells under the upper connecting levers of 1-, 2-
Bolt, 5- triangle yoke plates.
Specific embodiment
As shown in Figs. 1-2, the double sheets of ± 500kV duplexs hang V-type replacing insulator string bent plate fixture, including connecting lever, screw
Connect vertical core 3, bolt 4, triangle yoke plate 5；
The connecting lever is made of upper connecting lever 1 and lower connecting lever 2, and 120 degree of angles are formed between the upper connecting lever 1 and lower connecting lever 2,
Connecting hole is offered on upper connecting lever 1, screw connection vertical core 3 is offered on the lower connecting lever 2, upper connecting lever 1 is logical with triangle yoke plate 5
It crosses bolt 4 to connect, the bolt 4 is pierced by the connecting hole setting on connecting lever 1.
Further, rectangular through-hole is provided on the upper connecting lever 1, the rectangle that the triangle yoke plate 5 is clipped in connecting lever 1 leads to
In hole.
Further, 5 cross section of triangle yoke plate is isosceles triangle, and triangle yoke plate offers at 5 base center
Construction hole, the bolt 4 pass through the construction hole of connecting hole and triangle yoke plate 5 on upper connecting lever 1 to join upper connecting lever 1 and triangle
Plate 5 connects.
A kind of for replacing the double sheets of ± 500kV duplexs, to hang V-type replacing insulator string curved using provided by the utility model
When board has, the triangle yoke plate 5 that conducting wire is surveyed is clipped in the rectangular through-hole of upper connecting lever 1, upper connecting lever is vertically passed through using bolt 4
Upper connecting lever 1 is fixed with triangle yoke plate 5 for the construction hole of connecting hole and triangle yoke plate 5 on 1.The stick that is pulled will be connected
Screw pass through screw connecting hole 3, tower head side be pulled stick be connected to be fixed on tower head construction hole on connector.Lower connecting lever 2 is reversed
During stress, connection bolt 4 resists 5 side of triangle yoke plate.In operation process, operating personnel can be turned by tightening screw under making
2 stress of arm, the bottom of upper 1 rectangular through-hole of connecting lever resist 5 side of triangle yoke plate, insulator chain are made not stress, quickly insulation
The bulb of son takes out from bowl head, solves the problems, such as that existing connection mode cannot replace insulator using livewire work mode, carries
High power supply reliability.The configuration of the present invention is simple is light and handy, simple installation.
