Abstract
The utility model relates to a 10 kV junction box grounding wire, comprising three cable elbow type heads, wherein one end of each cable elbow type head is connected with a metal wire, three metal wires are fixed inside a connection wire clip and converged into one metal wire, the tail end of the metal wire is fixedly equipped with a copper terminal, and the copper terminal is fixed to a grounding apparatus through screws. The 10 kV junction box grounding wire has high safety for using, and the connection of the 10 kV junction box grounding wire and a junction box four-way mother board ensures both ends of a power failure line work segment to be grounded for achieving the purpose of the grounding wire, prevents inverted power delivery of lines, and ensures safety of work. The 10 kV junction box grounding wire enables the safe measure range to be narrowed, the number of groups of grounding wires to be reduced, and the power failure time to be shortened, and is simple in structure and convenient in use. The grounding wire mounting work can be finished by dismounting a 200 A protective cap or the elbow type heads and directly inserting a grounding wire into the 10 kV junction box after connecting a grounding end.
Description
Technical field
The utility model relates to the high-voltage electrical apparatus field, especially relates to a kind of 10kV coupling box earth connection.
Background technology
Can't enlarge the scope of safety measure at the coupling box hanging ground-wire in the prior art.
The utility model content
The technical problem that the utility model will solve provides a kind of safe, the anti-10kV coupling box earth connection that send electricity of the equipment that can prevent.
In order to solve the problem that prior art exists, the technical scheme that the utility model adopts is:
10kV coupling box earth connection; Include three cable elbow type heads; One end of each cable elbow type head is connected with plain conductor respectively; Plain conductor is fixed in the connecting clamp and pools a plain conductor, and the end of plain conductor is installed with copper tip, and copper tip is fixed on the grounding apparatus through screw.
Advantage and effect that the utility model had are:
1, the utility model 10kV coupling box earth connection is safe to use, through it and being connected of coupling box four-way busbar, guarantees dead line job step two-terminal-grounding, reaches the purpose of earth connection, prevents the anti-electricity that send of circuit, guarantees the safety of operation.
2, the utility model 10kV coupling box earth connection can dwindle the scope of safety measure, reduces the group number of ground wire, shortens interruption duration.
3, the utility model 10kV coupling box ground line configuration is simple, easy to use, removes 200A protective cap or elbow type head in the coupling box, connects and directly insert 10kV coupling box ground wire behind the earth terminal and promptly accomplish the earth connection installment work.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model 10kV coupling box earth connection.
Among the figure: cable elbow type head 1; Multiply annealed copper wire 2; Connecting clamp 3; Copper tip 4; Screw 5; Circular hole 6.
Embodiment
As shown in Figure 1, the utility model 10kV coupling box earth connection includes three cable elbow type heads 1, and described cable elbow type head 1 is used for being connected with coupling box four-way busbar.
One end of each cable elbow type head 1 is connected with a plain conductor respectively, and described plain conductor is processed by multiply annealed copper wire 2.Three plain conductors are fixed in the connecting clamp 3 and pool a plain conductor; The end of plain conductor is fixed with copper tip 4, and copper tip 4 is processed by copper sheet, and its center is provided with circular hole 6; Screw 5 is connected copper tip 4 on the coupling box door lock through circular hole 6, to guarantee ground connection.
Claims (1)
1.10kV coupling box earth connection; It is characterized in that including three cable elbow type heads; One end of each cable elbow type head is connected with plain conductor respectively; Plain conductor is fixed in the connecting clamp and pools a plain conductor, and the end of plain conductor is installed with copper tip, and copper tip is fixed on the grounding apparatus through screw.
