Description
Technical field
The present invention relates to a kind of ground lines, and in particular to a kind of dropping-proof hook ground line.
Background technique
With the development of China's power grid and the acceleration of urbanization process, power transmission line corridor resource becomes more and more nervous,
More back transmission line parallel erected on same tower or the phenomenon that setting up in parallel with corridor, have become the norm.
To reduce power off time, power supply reliability is improved, multi-circuit lines on the same tower is frequently with a line outage, other circuits
The mode of normal operation.Since there are the couplings in electric field and magnetic field between working line and dead line, on dead line often
Induce very high voltage and current, if working ground wire and conductive contact loosely, vibration or swing and will cause ground line
Fall off so that be grounded with conducting wire repeatedly arcing burn conducting wire, cause wire strand breakage, also will affect operating personnel the person peace
Entirely.
Work on hand ground line is to throw hanging ground line, by ground connection end terminal, insulating cord, short-circuit line, conducting wire end terminal group
At；The supporting post-rod that is impacted downwards in wire clamp using the self gravity of conducting wire end terminal is simultaneously allowed to be detached from support to discharge pin shaft
On spring force clamp conducting wire.Conducting wire end terminal connection ground line and power transmission line, are the key that short-circuit grounding wires, directly certainly
Surely what is be grounded assembles and disassembles the reliability of just property and connection.And when assembly and disassembly short-circuit grounding wire, operator must keep with power transmission line
The voltage of safe distance appropriate, power transmission line is higher, and required safe distance is bigger, and safe distance needed for ultra high-tension transmission line is high
Up to several meters, which increase the assembly and disassembly difficulty of short-circuit grounding wire conducting wire end terminal.
In actual operation, discovery ground line has the disadvantage that
(1), ground line is the supporting post-rod impacted downwards in wire clamp using the self gravity of conducting wire end terminal and is allowed to de-
From support to discharge the spring force on pin shaft to clamp conducting wire, longer relatively thick due to being grounded, own wt is much larger than and leads
The weight of line end wire clamp, so that the downward impact force of wire clamp is inadequate, the supporting post-rod in wire clamp cannot be detached from support.
(2), the trigger sensitivity of conducting wire end terminal is low, can only control vertical direction movement, under the action of the wind, conductor wire end
Wire clamp is difficult to clamp conducting wire, and difficulty is big, time-consuming, and connects less reliable stabilization, has not only influenced power failure emergency repair time, but also exist
The risk for destroying system stability causes larger difficulty to installing ground line.
(3), the elastic force of spring can only be overcome by firmly pulling insulating cord upwards when removing, finally by conductor wire end wire clamp
Extracted from conducting wire, not only remove it is laborious, firmly conference so that operator is easy to happen danger, but also transmission of electricity may be damaged
Conducting wire.
So assembly and disassembly conducting wire end terminal has become the restriction " bottleneck " of ultra high-tension transmission line interruption maintenance work, it is necessary to change
Increase the connection reliability of ground line into the conducting wire end terminal of existing short-circuit grounding wire to shorten the time of assembly and disassembly ground line
And stability.

Specific embodiment
Specific introduce is made to the present invention below in conjunction with the drawings and specific embodiments.
A kind of anticreep end terminal, including clamp 1 and the de- bar 2 of extension, hang one end of de- bar 2 by being set on the middle line of clamp 1
Pin shaft 9 be fixed on the top of clamp 1.
Clamp 1 is U-shaped, bottom end opening, intracavitary to set conductor grip 5；Clamp 8 of the conductor grip 5 by a pair with camber line groove forms；
The both ends of clamp 8 are individually fixed in 1 cavity wall of clamp, and camber line groove is oppositely arranged, and the notch of conductor grip 5 is spacious in gradual change outward
Mouthful；And spring 7 is equipped between clamp 8 and the arm body of clamp 1.Preferably, which is set as different curvature, outside
Endpoint shifts to install.
The other end for hanging de- bar 2 is fixed by hooking slot 10 and an arm body of clamp 1；It hooks slot 10 and hangs consolidating for de- bar 2 by being set to
Rationed marketing and the card slot composition on an arm body of clamp 1；Preferably, under closed state, an arm body of de- bar 2 and clamp 1 is hung
In closed state；And hang de- bar 2 and be additionally provided with auxiliary dropping device, the spring 11 that falls off including being set to clamp 1, and be set to and hang de- bar
Column 12 is suppressed on 2.
It is designed according to use demand, the side which may be configured as hanging de- bar 2 and an arm body of clamp 1 overlaps, or
The overlapping slot that can accommodate an arm body of clamp 1 is arranged in the medial surface for hanging de- bar 2.
In use,
As shown in Figure 1, the end of any arm body of clamp 1 hangs the another of de- bar 2 by 3 hole dead earth lines 3 of ground line
End passes through the fixed insulating cord 4 in 4 hole of insulating cord.Under this state, it hooks slot 10 and is in closed state, is i.e. fixed pin is fastened on card slot
It is interior, meanwhile, it suppresses column 12 and oppresses the spring 11 that falls off.
As shown in Fig. 2, under being stretched end terminal by steel tower cross-arm side by insulating cord 4, and the open end of clamp 1 is hooked and is led
Line firmly tenses insulating cord 4 upwards, and high-voltage conducting wires are sticked into conductor grip 5(camber line groove) in.
As shown in figure 3, loosening insulating cord 4 after ground line 3 is connect with high-voltage conducting wires, in end terminal and it is grounded 3 certainly
Under the action of weight, using the high-voltage conducting wires in camber line groove as axis, end terminal rotates 180 degree around conducting wire, and the opening of hook is from turn
Downwards, to realize the secured connection between conducting wire and wire clamp.
As shown in figure 4, pulling up insulating cord 4 after work is completed, the fixed pin of de- bar 2 is hung out of, arm body card slot
It skids off, during pulling, the elastic force auxiliary for the spring 11 that falls off hangs de- bar 2 and is detached from arm body.Under a stretching force, de- bar 2 is hung around pin
Axis 9 rotates 180 degree；It continues up and draws insulating cord 4, entire wire clamp is detached from high-voltage conducting wires.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the above embodiments do not limit the invention in any form, all obtained by the way of equivalent substitution or equivalent transformation
Technical solution is fallen within the scope of protection of the present invention.
