The portable grounding wire for power line maintenance comprises an insulation rod, a grounding body and a connecting soft copper wire, wiring heads at the two ends of the connecting soft copper wire are respectively connected with a metal clamp of the insulation rod and the grounding body through screws in a matching way. The portable grounding wire for power line maintenance is characterized in that the grounding body is provided with double rod ingots; upper rods of the two rod ingots are sleeved at the upper end of the grounding body through pipe sleeves connected with the two rod ingots in an integrated way and are then fixed through screws; and lower rods of the two rod ingots are sleeved on the lower part of the grounding body through pipe sleeved connected with the two rod ingots in an integrated way and are then fixed through screws. The utility model has the advantages that the efficiency of winding of the connecting soft copper wire is high, the service life of the connecting wire is prolonged, the labor is saved, the portable grounding wire for power line maintenance is neat and beautiful when being accommodated for storage, and the added value is increased.
Description
Technical field
The utility model relates to a kind of portable earth connection that power circuit is used that overhauls, and is applied to power circuit when maintenance with job site with may send electricity to introduce the earth simultaneously to each phase place branch line of dead line job site.
Background technology
The earth connection that existing maintenance power circuit is used is made up of insulating rod, earth electrode, connection annealed copper wire, connects the connector lug at annealed copper wire two ends, and flat with holes, metal clamp, the earth electrode by screw and insulating rod is fastened respectively.Owing to require high current load, connect annealed copper wire and adopt the 25mm2 multiply annealed copper wire of transparent sheath to be made.The insulating rod termination has special-purpose wire clamp.Insulating rod has four, is respectively applied for each phase place power line of clamp.
Earth electrode is the metal stake that a round steel is made, and following has the stake point, is convenient to hammering and inserts the earth.Existing maintenance power circuit earth connection, its weak point are to take in the keeping state, use the connection annealed copper wire that four insulating rods and earth electrode are wound up, and are bundled into one.During use, need 2～3 people to untie connecting annealed copper wire one circle circle temporarily.It is all very consuming time, very inconvenient that the collection keeping is untied, twined in interim use.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, provides a kind of collection keeping to overhaul the power circuit earth connection easily.
The purpose of this utility model can reach like this: the portable earth connection that the maintenance power circuit is used, be made up of insulating rod, earth electrode, connection annealed copper wire three parts, the connector lug that connects the annealed copper wire two ends is matched by metal clamp, the earth electrode of screw and insulating rod respectively; It is characterized in that installing on the earth electrode two bar ingots; The upper boom of two bar ingots is enclosed within the earth electrode upper end by the pipe box that is connected with its one and fixes with screw; The lower beam of two bar ingots is enclosed within the earth electrode bottom by the pipe box that is connected with its one, and fixes with screw.
The portable earth connection that above-mentioned maintenance power circuit is used is characterized in that earth electrode is carved with the dark mark of limit apart from the sharp 60 centimeters places of stake.
The utlity model has following advantage:
1, two distance between tie rods of two bar ingots can transfer to very greatly, connect annealed copper wire and are wrapped in above it, and the coiling length of each circle is also just bigger, winding efficient height.
2, the number of turns of Chan Raoing is few, has prolonged the useful life that connects annealed copper wire.
3, twine, untie a people and just can finish alone, need not other people help, saved the labour.
4, take in keeping state neat appearance, improved added value of the present utility model.
Description of drawings
Accompanying drawing is the utility model structural representation.
1 is insulating rod among the figure, the 3rd, connect annealed copper wire, and the 5th, earth electrode, the 7th, lower beam, the 9th, pipe box II, the 10th, the dark mark of limit, the 11st, upper boom, the 13rd, pipe box I.
Embodiment
The utility model is further described below in conjunction with accompanying drawing.The portable earth connection that the maintenance power circuit is used, form by insulating rod (1), earth electrode (5), connection annealed copper wire (3) three parts, the connector lug that connects annealed copper wire (3) two ends, flat band diplopore, matched by metal clamp, the earth electrode (5) of screw and insulating rod respectively.Earth electrode (5) has a two bar ingot, and annealed copper wire (3) is used to be intertwined and connected.The upper boom of two bar ingots (11) is enclosed within earth electrode (5) upper end by the pipe box I (13) that is connected with its one and fixes with screw.The lower beam of two bar ingots (7) is enclosed within earth electrode (5) lower end by the pipe box II (9) that is connected with its one and fixes with screw.
The fixed-site of upper boom (11) is at upper end, and pipe box I (13) adopts metal material to make, and the outside makes and is connected the matched interface of annealed copper wire (3) joint.Pipe box II (9) then is made into movable, and its holding screw adopts the butterfly screw, is convenient to hand tighten screw and tightens or loosens pipe box II (9), regulates the fixed position of lower beam (7) on earth electrode (5).For guarantee that all kinds of production operation personnel of system of Utilities Electric Co. correctly use, take care of, maintenance and advance copy utility model, guarantee that the utility model tool is functional, guarantee the person, equipment, power grid security, the connector lug that connects annealed copper wire (3) two ends should guarantee to contact well with clamp, the earth electrode of insulating rod, easy accessibility, enough mechanical strengths are arranged, and unlikely loosening when big short circuit current passes through.Thereby connector lug adopts two screws to fix, and in the time of as if the single screw of use fixedly, should install spring shim additional, and is loosening to prevent fixed screw.
Because the position of lower beam (7) on earth electrode (5) of two bar ingots is adjustable, can select the fixed position of lower beam (7) when being intertwined and connected annealed copper wire (3) according to the length that connects annealed copper wire (3), and then make the distance between two bars bigger, and reduce and twine the number of turns, reduce the winding time.Obvious this canoe, every circumference are very long, have also just significantly reduced the quantity at deep camber place in the connection annealed copper wire (3), and not only a people can independently finish, and collects, deposits neat appearance, but also has improved the useful life of connection annealed copper wire (3).
Utilization for convenience, a dark mark of limit (10) can also be carved by 60 centimeters places of the utility model earth electrode (5) distance stake point.
When the utility model uses, take off connection annealed copper wire (3), will connect annealed copper wire (3) other end and insulating rod and connect from two bar ingots.The lower beam (7) of loosening two bar ingots upwards moves to the top with pipe box II (9) along earth electrode (5) and fixes.Again the earth being gone in earth electrode (5) hammering is clipped on the power circuit to limitting the dark degree of depth of marking (10), can hanging insulating rod (1) one by one.Finish using, transfer to earth electrode (5), lower beam (7) is fixing in position, remove from insulating rod connecting annealed copper wire (3) again, be wrapped on two bar ingots.At last, also use four insulating rods and earth electrode tightrope, band to tie up and get final product, use convenient next time together.
