Abstract
The utility model relates to an arc-protection grounding wire clamp. The wire clamp comprises an upper press plate and a lower press plate, which are fastened to each other. Pricking teeth are formed on the matching surfaces of the upper press plate and the lower press plate respectively. A grounding wire rack is arranged below the lower press plate. An arc-discharge pole and an arc-guide pole are arranged at the lower end of the grounding wire rack. The arc-protection grounding wire clamp has the advantages of compact structure, good lightning-protection effect, high security of wire maintenance staff, multiple functions, low installation cost, flexible selection of installation site, convenient design and arrangement and full utilization of equipment performance.
Description
Technical field:
The utility model relates to the preventing arc wire clamp of using on a kind of electric power overhead insulated cable.
Background technology:
All need to be provided with the preventing arc wire clamp on the general electric power overhead cable, when thunderbolt, electric current can be bled off.Simultaneously, generally also need on the overhead wire to install ground loop is set, hang up earthing tool when being used for situation such as power line maintenance, guarantee personal security.These devices are located at all that not only installation workload is big on the overhead wire, the equipment cost height, and also the installation site also may repeat, and the complexity of design increases, and equipment performance also may be restricted.
Summary of the invention:
At the deficiencies in the prior art, the utility model provides a kind of compact conformation, the preventing arc earthing clamp of diverse in function.
The utility model comprises the top board and the lower platen of mutual fastening, is equipped with the puncture tooth on the mating surface of upper and lower pressing plate, and the below of lower platen also is provided with the ground connection hanger, puts the lower end that the arc utmost point and the striking utmost point then are located at the ground connection hanger.
Compact conformation of the present utility model has anti-lightning strike function, also is provided with the ground connection hanger simultaneously, guarantee personal security when making things convenient for the lead maintenance, the integrated of various function not only reduced the installment work cost, and makes the selection of installation site more flexible, layout is convenient, gives full play to equipment performance.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings:
Fig. 1 is the main structure schematic diagram of embodiment;
Fig. 2 is the left view of Fig. 1.
Embodiment: as shown in the figure, top board 1 and lower platen 2 fasten mutually, are equipped with puncture tooth 3 on the mating surface of upper and lower pressing plate, and the below of lower platen 2 also is provided with ground connection hanger 4, puts 6 lower ends that are located at ground connection hanger 4 of the arc utmost point 5 and the striking utmost point.General lower platen 2, ground connection hanger 4, put the arc utmost point 5 and the striking utmost point 6 is the integral molding structure, convenient for production, the security performance of discharge is reliable.Top board 1 and the lower platen 2 general bolts 7 that pass through fasten mutually, can be provided with torque nut 8 at the head of bolt 7, and the dynamics of control puncture is easy like this, and it is more accurate to install.
During use, top board 1 and lower platen 27 are fastened on the aerial insulated cable 3 of teeth of the puncture contact conductor wire that can puncture by tighting a bolt.During thunderbolt, electric current can be emitted with electrical arc by putting the arc utmost point 5, and 6 of the striking utmost points can draw the outage arc.When needing the maintenance cable, earthing tool then can be articulated on the ground connection hanger 4, and is easy to operate, safe and reliable.
