Description
Technical field
The utility model relates to a kind of ground line, it is particularly suitable for the 10kV power cable branch box used when interruption maintenance
It is grounded with rear T-type.
Background technique
With the development of power industry and being constantly progressive for society, 10kV power cable line gradually increases, adjoint
Be then that the equipment failure rate of 10kV power cable line increases, and especially 10kV power cable branch box, the equipment do not have
Earthing switch function.The connection of T-shape end, the side of conventional mounting ground line are generallyd use inside 10kV power cable branch box
Formula is exactly to remove plug after arrester first, and arrester of dismantling removes connecting screw, then removes cable head casing tube, is finally removed
Traditional grounding wire mounting could be located at feeder pillar screw rod or hung on feeder pillar screw rod by T-shape end.This operating process
It having disadvantages that: needing device for disassembling before installing ground line, electric shock risk increases, and it is dangerous, and this operating process need to remove
Plug after arrester, remove arrester, remove connecting screw, then remove cable head casing tube, could extract out cable connecting terminal and
Ground line connection, front and back needs 6 steps；It installs one group of ground line and at least needs 30-45 minutes, and after work, removed
Items of equipment is both needed to be reinstalled, in this way in disassembly process, it is also possible to which injury device and end, there are security risks.
" ground connection " is an important protection safety measure of interruption maintenance operation, at this stage, in 10kV overhead transmission line often
Ground line is mainly bayonet type and coupling type, when 10kV power cable branch box inspection earthing, the ground connection of no application specific standard
Line, bayonet type and coupling type are grounded there is difficult to install, specification disunity, standard disunity, dismantle using inconvenient to carry
The disadvantages of, it is grounded for this reason, it is necessary to innovate a kind of 10kV power cable branch box that can solve the above problem with rear T-type, with
Reach that installation process is simple, uniform specification, is easy to carry about with one, safer requirement.
Summary of the invention
The purpose of this utility model is the safety and efficiency to improve the maintenance of 10kV power cable branch box, reduces installing
For the purpose of complicated procedures in the process, develops a kind of 10kV power cable branch box and be grounded with rear T-type.
In order to realize the purpose of this utility model, used technical solution are as follows: a kind of 10kV power cable branch box use
T-type is grounded afterwards, including insulating bar, ground line and ground line fixture, it is characterized in that: the connecting terminal of the ground line
For threaded female hair style terminal, the rear end of threaded female hair style terminal and ground line and insulating bar are interconnected, threaded female hair style
Terminal is connected with the connecting screw rotation for being mounted on after cable in T connector.This ground line, by traditional ground line bayonet type or
Coupling type connecting terminal is adapted as threaded female hair style terminal, and threaded female hair style terminal rear end, 25 square millimeters of ground lines, 10kV are exhausted
Edge operating stick is interconnected by screw thread female, then threaded female hair style terminal is mounted on after cable in T connector.In use, only
Plug after arrester need to be removed, the connecting terminal rotation connection of ground line directly can be realized to the purpose of safety ground.
The utility model, relative to the installation method of traditional installing ground line, does not have to dismantling cable in installing process
Head is directly connect with end, and job security greatly improves, and the operating time greatly shortens, and working efficiency greatly improves.It can be with
Bring it is following the utility model has the advantages that
1, the safety is improved for work.When installing, do not have to remove end, it only need to will be after the arrester that connect with end
Plug remove, expose connecting screw, ground line can directly knob on end connecting screw.It avoids largely removing to install keeping away
This Risks point of the equipment such as thunder device, end, the safety of work greatly improve.
2, the efficiency to work improves.Compared with conventional method installing ground line, 10kV power cable branch box is connect with rear T-type
Ground wire installing is simple, and working efficiency greatly improves.
3,10kV power cable branch box is grounded with rear T-type, and terminals are using the screw thread female structure created.This knot
Structure can be connected with the direct knob of the connecting screw in end, during installation, without removing end, as long as removing and cable
Plug after the arrester of head connection, and screw thread female connecting terminal is mounted on after cable in T connector, substantially increases safety.
4, ground line is connected firmly.Ground line uses screw thread female structure, and terminals knob is on connecting screw.Compared to biography
Bayonet type, the dropper of system are fixed, and this mode is stronger, and do not allow connecting screw easy to wear, and 10kV power cable point
Branch case is grounded with rear T-type and is equipped with plurality of specifications screw thread female connecting terminal, can be met various sizes of connecting screw and be connect
The requirement of ground wire.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.

Specific embodiment
A kind of 10kV power cable branch box described in the utility model is grounded with rear T-type, including insulating bar 1,
Ground line 5 and ground line fixture 6, the connecting terminal of ground line are threaded female hair style terminal 2, after threaded female hair style terminal 2
End is interconnected with ground line 5 and insulating bar 1, the internal screw thread of threaded female hair style terminal 2 and is mounted on T connector 3 after cable
Interior connecting screw 8 is threadedly engaged, and threaded female hair style terminal 2 connects with the rotation of connecting screw 8 for being mounted on after cable in T connector
It connects.
Traditional ground line bayonet type or coupling type connecting terminal are adapted as threaded female hair style terminal, spiral shell by the utility model
Line female formula terminal rear end, 25 square millimeters of ground lines, 10kV insulating bars are interconnected by screw thread female, screw thread female
Formula terminal is mounted on after cable in T connector.The present embodiment during installation, only need to remove plug after arrester, directly by 10kV electricity
The rear T-type of power cable branch box is grounded rotation connection, completes installation 10kV power cable branch box and is grounded with rear T-type；It tears open
Except when, only need to remove 10kV power cable branch box and be grounded with rear T-type, a whole set of peace can be completed in plug after zinc oxide surge arresters
Assembly and disassembly remove process.And tradition ground line is during installation, need to successively remove plug, dismounting arrester, dismounting connection spiral shell after arrester
Bar 8 removes cable T end protective cover 4, then conventional bayonet is grounded and is installed；When dismounting, conventional bayonet ground connection need to be successively removed
Line, installation cable T end protective cover 4 install plug after connecting screw 8, zinc oxide surge arresters, zinc oxide surge arresters, can complete a whole set of peace
Assembly and disassembly remove work.
