Technical field
Ground protection field of tool when the utility model relates to power transmission lines overhauling is specifically related to a kind of earthing lines of power transmission lines overhauling device.
Background technology
Earth connection is the security tool that often uses during electric power safety is produced; power failure, electrical verification, hanging earthing conductor are the important technique measure that guarantees transmission line interruption maintenance safety; being that the protection staff prevents the reliable and secure measure of incoming call suddenly in the job site, is the important assurance of personal safety and device security.Because the installing earth connection is in order to protect the safety in electric maintainer's operating process, if the ground wire installation position is not right, then not have protection personnel's effect; Simultaneously, if after power transmission lines overhauling is finished untimely dismounting ground wire, can cause that then the band ground wire send the serious accident of electricity, therefore preventing charged hanging ground-wire and band ground wire, to send electricity be the key of transmission line electric " five is anti-".
The earth connection function of earthing tool widespread usage is comparatively single in the existing transmission line, in reality maintenance and track remodelling construction, when with the operation of the different circuits of tower and different specialty, a plurality of working groups, every ground wire of a plurality of earth points lacks the necessary information that guarantees that safety is required owing to do not have the collection and the control of information source.The high voltage of especially how tame condominium, remote circuit transprovincially, during provisional operation such as net, office, because distribution line branch earth point is many, relate to how tame units such as power supply, user, need comprehensive ground connection information especially, and existing earthing tool can not provide such information source, therefore maintainer's mistake takes place easily step on charged shaft tower accident.
Plan and specifically implement the operation or work standard requirement according to earthing tool, homework type and the maintenance of whole electrical network, existing main earth connection method for security protection, normally arrange according to operation plan and unified the power failure, work unit is according to work ticket row fixed earth connection group number and shaft tower contrast, after treating that the whole piece circuit has stopped electricity, send work order; The staff handles work ticket, explains safety measure and dangerous spot; The operating personnel arrives work ticket institute column position, electrical verification, does the grounding safety measure that needs protection, and protection section both sides need a plurality of working groups carry out the ground protection measure.When stepping on the bar work high above the ground, electric pressure is high more, and the distance of earth point and lead is also big more, and the overhead line structures corner number of degrees are big more, and earth connection just requires long more, does not just allow easy to hang during personnel's operation more; Sometimes meet wind, the needed suspension time of operation is just longer.On the operation process king-rod with bar under the personnel labor intensity height, cause muscular fatigue to cause danger easily.Particularly the high-altitude falling accident very easily takes place in the operating personnel of shaft tower; Because the earth connection suspension time is long, active section can not get protection, and other working group also can't start working, and will influence job schedule and incur loss through delay the activity duration.
Summary of the invention
The technical problems to be solved in the utility model is: the earthing lines of power transmission lines overhauling task difficulty of existing structure is big, activity duration is long, and owing to lack work permit people command link information and tower spotting information source, mistake takes place and steps on charged shaft tower accident problem in maintainer easily.
The technical solution of the utility model is: a kind of earthing lines of power transmission lines overhauling device, comprise and to articulate and the conductor wire end wire clamp of removing, the earth terminal geometrical clamp that can be fastenedly connected with earth terminal and the ground short circuit line that is connected both with transmission line, described conductor wire end wire clamp also is connected with one and is used for the conductor wire end wire clamp and articulates insulation rope with dismantling operation, it is characterized in that, a GPS information transceiving device also is installed on the earth terminal geometrical clamp.
Further, described conductor wire end wire clamp also is equipped with hook and flat thin magnet.
The utility model has following advantage compared with the prior art:
1, the utility model is owing to installed a GPS information transceiving device on the earth terminal geometrical clamp, increased the earthing tool information source, GPS fixed point tower grounding information and work permit people command link information can be provided, work permit people can be at a plurality of different locations and working group, assign the ground connection information of instructing and obtaining circuit, guarantee that earth connection hangs the shared of the correct and ground connection information in place, avoid mistake to hang to tear open with the maintainer by mistake and walked the incidental danger of wrong position in the line process hangingly, guaranteed maintainer's safety.
2, the utility model is owing to adopted hook at the conductor wire end wire clamp, conductor wire end ground connection folder adopts the method for reversal of the natural order of things, solved excessive because of the circuit corner outside, extra high voltage line lead distance to the ground big, earth connection is long, because of difficult problems such as strong wind wave, guaranteed under the various shaft tower angles and the suspension of earth clip under certain windage yaw.
3, the utility model is owing to installed flat thin magnet additional at the conductor wire end wire clamp, reached purpose to the adhesive of lead steel core, the adhesive of magnetic material makes the suspension ground wire be convenient to operation more, particularly be not easy to be blown displacement by strong wind, increase the stability of earth point absorption, also improved the operating efficiency of earth point.
4, earth clip of the present utility model adopts hook and flat thin magnet structure, has reduced task difficulty.Need 2 people on the former operation bar, need 1 people's operation to get final product on the utility model bar, personnel can will the adjustment of hitch point length distance accomplish optimization simply on bar, realize laborsaving, save time, reduce because of excessive the waving of causing of operation distance, guarantee operating personnel's steadily of centre of gravity on the bar, be simple and easy to grasp, realized safety, reliable operation
5, compare with traditional earthing tool, the utility model operation easier reduces greatly, has reduced staff's labour intensity and the activity duration, has guaranteed safety in production indirectly, has improved efficiency.
