Technical field

The utility model belongs to high-voltage earthing line technology field, is specifically related to a kind of portable 10KV high-voltage earthing line.

Background technology

Existing 10KV high-voltage earthing line is made up of three insulation earth rods, ground connection copper cash and ground studs, and wherein, the insulation earth rod is formed by fixedly connecting by 1.5 meters long insulating rods and ground connection hook.Press code requirement, need when depositing insulation earth rod, ground stud are left concentratedly separately, leave in the ground connection copper cash in the bag separately; During use, need earlier ground connection copper cash and three ground connection hooks and ground stud to be connected, ground stud is squeezed in the ground again, the hand-held earth rod that insulate of last artificial upper boom is installed on ground connection hook on the high-voltage line.There is following weak point in existing 10KV high-voltage earthing line: the one, need during execute-in-place earth rod, ground stud, ground connection copper cash are connected one by one, and spended time is longer; The 2nd, the on-the-spot connection, connection reliability is easy because of the people, exists to connect the hidden danger that gets loose; The 3rd, the ground connection hook is fixedlyed connected with insulating rod, and insulating rod is shorter, and load is heavy during operating personnel's pole-climbing, and the distance between high-voltage line is little, and is dangerous relatively large; The 4th, insulation earth rod quantity is many, deposits, carries and use all inconveniences; The 5th, insulating rod price height not only makes cost increase, and makes and detect maintenance cost at ordinary times and increase; The 6th, when meeting the operation of multi-layer high-voltage wire loop border, the insulation joint bar interts inconvenient, needs sometimes laterally to place, and operation is inconvenient especially.

Summary of the invention

The purpose of this utility model provides a kind of being convenient to deposit, carry at above-mentioned weak point exactly, and is easy and simple to handle, and the efficient height is safe and reliable, the portable 10KV high-voltage earthing line that maintenance cost is low.

Technology technical solution of the present utility model is: a kind of portable 10KV high-voltage earthing line, the insulating rod that comprises three ground connection hooks, ground stud, ground connection copper cash and tape insulation caput, it is characterized in that: the insulating rod joint of a ground connection hook is provided with the draw-in groove that cooperates with insulation caput on the insulating rod in described three ground connection hook, and the sidepiece linked up with of two ground connection is provided with link in addition; The ground stud upper end is provided with fixing last drum bar, the following drum bar of bottom suit activity, and following drum bar is provided with standing screw; The ground connection copper cash is fixedly connected between three ground connection hooks and the ground stud.

The top of the insulation caput of the insulating rod described in the technology technical solution of the present utility model is provided with the threaded connector that can be connected with electroscope.

The utility model is owing to have the draw-in groove that cooperates with insulation caput on the insulating rod on the insulating rod joint of a ground connection hook in three ground connection hook, on other two ground connection hooks, be provided with snap ring, the upper end of ground stud be provided with fixing on the drum bar, be provided with drum bar under the activity of suit in the bottom of wiring pile, and the ground connection copper cash is fixedly connected between three ground connection hook and the ground stud, thereby when depositing, to descend the drum bar to move earlier and stubborn consolidating in the wiring pile lower end, wiring pile and last like this, following drum bar just forms drum, the ground connection copper cash is installed around last, between the following drum bar, and three ground connection hook put into the interlayer that the ground connection copper cash forms, make its volume minimum, can put into corresponding little chest; During use, can directly, little chest of the present utility model be carried into the work-yard with being housed, cooperate the general insulating rod that has the insulation head after the taking-up again, can carry out the upper boom operation, to be fixed on the insulation caput of insulating rod with the ground connection hook of draw-in groove earlier, and on the high-voltage line in the middle of being mounted on, withdraw from insulating rod then, by link other two ground connection are mounted on the high-voltage line of both sides respectively again, promptly finish the operation of one group of high-voltage earthing line, not only save the line connect hours, and finish also shortening greatly of the time of mounting.The utility model has saved original three 1.5 meters long insulating rods, has not only saved cost, also makes to deposit, carry convenient, has also exempted the every year of insulating rod and detect to have safeguarded.The utility model is owing to adopt general insulating rod, and the operation of at every turn going out of this insulating rod all will be carried, thus can not increase earth connection cost, deposit and carry, and, insulating rod is the longest to be 3 meters, and operating personnel's pole-climbing dais is reduced, and fail safe improves greatly.Because the ground connection copper cash is fixedlyed connected with ground stud with the ground connection hook, deposits, need not when using dismounting or installation at this, and connection reliability is improved greatly, saves connection or dismounting time simultaneously.Owing to no longer include fixedly connected insulating rod on the ground connection hook, thereby the utility model is in light weight when being used for the operation of multi-layer high-voltage line, and it is convenient especially to hang.The utility model is owing to be provided with threaded connector on the insulation head of insulating rod, thereby can be used for on-the-spot electrical verification operation after connecting electroscope.The utility model is mainly used in the earth connection of 10KV high-voltage line.
