Abstract
The utility model relates to a grounding device used in power equipment in electric system, particularly to a complete set of dedicated grounding wire for junction boxes, which comprises three insulated grounding bars that respectively communicates via multiple annealed copper wires and then are connected with a ground clamp. The complete set of dedicated grounding wire has the advantages of simple structure, convenient operation, firm connection, and good safety and reliability.
Description
Technical field:
The utility model relates to the earthing device of using on the power equipment in a kind of electric power system, especially a kind of Specialized Set Earth Wire of Branched Case.
Background technology:
Cable branch box is in the distribution line, cable and cable, and the intermediate member that cable is connected with other electric equipment, it is simple and convenient that it connects compound mode, flexibly, is widely used.When feeder pillar is overhauled, according to national associated safety regulation, should be on power distribution equipment the earth connection of installation qualification, the service work that can be correlated with, the electric capacity in the releasable cable can prevent that on the one hand incoming call injures the maintainer suddenly so on the one hand.When the maintainer overhauls feeder pillar now, be that the maintainer puts on insulating gloves mostly, then fine copper wire be wrapped in respectively on the threephase cable terminal, and then ground connection.Owing on the threephase cable terminal corresponding insulation guard shield is arranged all, so carrying out earth connection when operation inconvenience very, connect also insecurely, and method of operation does not meet corresponding national security yet and stipulates like this, be easy to the maintainer is damaged, dangerous.
The utility model content:
The utility model provides a kind of Specialized Set Earth Wire of Branched Case, and it is simple in structure, and is easy to operate, is connected firmly, safe and reliable, solved problems of the prior art.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises that three thoroughly do away with the edge earth rod, and three thoroughly do away with the edge earth rod is connected by the multiply annealed copper wire respectively, is connected with earth clip again.
Described insulation earth rod comprises insulating rod, is fixed with earth rod at the front end of insulating rod, and movable sleeve is connected to the rotation earth electrode in the rear end of earth rod, and the multiply annealed copper wire is fixed on the rotation earth electrode by screw, is provided with nut in the front end inside of earth rod.
The utility model adopts three to thoroughly do away with the edge earth rod, three thoroughly do away with the edge earth rod is connected by the multiply annealed copper wire respectively, be connected with earth clip again, described insulation earth rod comprises insulating rod, at the front end of the insulating rod earth rod that is connected, front end inside at earth rod is provided with nut, at the rear end of earth rod pivot bush unit rotation earth electrode, the multiply annealed copper wire is fixed on the rotation earth electrode by screw, put on insulating gloves like this, when hand takes insulating rod to operate again, can make the maintainer avoid touching earth connection or unearthed conductor easily with firm being connected of earth connection and conductor end, to prevent that induced electricity from getting an electric shock, make operation meet corresponding national security regulation, simple and convenient, safe and reliable.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A portion enlarged drawing among Fig. 1.
Among the figure 1, insulating rod; 2, earth rod; 3, rotation earth electrode; 4, nut; 5, multiply annealed copper wire; 6, earth clip.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in FIG., the utility model comprises that three thoroughly do away with the edge earth rod, and three thoroughly do away with the edge earth rod is connected by multiply annealed copper wire 5 respectively, is connected with earth clip 6 again.Described insulation earth rod comprises insulating rod 1, front end at insulating rod 1 is fixed with earth rod 2, be connected to rotation earth electrode 3 at the rear end of earth rod 2 movable sleeve, multiply annealed copper wire 5 is fixed on the rotation earth electrode 3 by screw, is provided with nut 4 in the front end inside of earth rod 2.
During use, the maintainer puts on protective device, opens feeder pillar, respectively the protection cover cap on the threephase cable is taken off.Then earlier with earth clip 6 ground connection, hand is taken insulating rod 1 again, nut 4 spirals of earth rod 2 front ends are connected on the corresponding threephase cable, multiply annealed copper wire 5 firmly is connected with conductor end with earth rod 2 by rotation earth electrode 3, operation meets the relevant security regulations of country like this, both simple and convenient, safe and reliable again.
Claims (2)
1, a kind of Specialized Set Earth Wire of Branched Case is characterized in that: comprise that three thoroughly do away with the edge earth rod, three thoroughly do away with the edge earth rod is connected by the multiply annealed copper wire respectively, is connected with earth clip again.
2, Specialized Set Earth Wire of Branched Case according to claim 1, it is characterized in that: described insulation earth rod comprises insulating rod, front end at insulating rod is fixed with earth rod, movable sleeve is connected to the rotation earth electrode in the rear end of earth rod, the multiply annealed copper wire is fixed on the rotation earth electrode by screw, is provided with nut in the front end inside of earth rod.
