Description
Technical field
A kind of ground wire is the utility model is related to, more particularly to a kind of cable elbow-shaped head ground wire, belongs to electrical equipment and connect
Ground technical field.
Background technology
Two kinds of situations are stated in the presence of current power distribution network：First, the AC metal closed formula switchgears of 10 kV are configured without connecing
Ground switchs；2nd, 10kV distribution cables circuit is without switching cable distribution box by getting in touch with, that is, we are usually said hard connects
Connect, either switchgear be configured without earthing switch or cable all can be to cable run, switchgear and logical by Hard link
The maintenance for crossing the hardwired transformer of distribution box brings great inconvenience, switchgear and the not cable of belt switch point in power distribution network
It is different with conventional ground wire when using ground connection to connect case, because conventional ground wire is only applicable to aerial condutor, and opens
Close cabinet and the cable distribution box of belt switch is not then cable-type, however it is current also without the ground wire of cable-type, using
It is very inconvenient in journey.
The content of the invention
The technical problems to be solved in the utility model is：A kind of cable elbow-shaped head ground wire is provided, it is a kind of for opening
Close cabinet（The not cable distribution box of belt switch）Cable elbow-shaped head ground wire, it is detachable by being set in one end of insulating bar
Elbow-type head connecting rod, elbow-type head connecting rod is connected with grounded probe with annealed copper wire, when in use can be as needed, by elbow-type
The elbow-type head of head connecting rod and switchgear installs or removes, and the function being grounded is easy to operate, solves above-mentioned ask
Topic.
The technical solution of the utility model is：A kind of cable elbow-shaped head ground wire, it includes grounded probe, insulating bar
With elbow-type head connecting rod, one end of the grounded probe is taper, and the side of the other end is fixedly connected with fixed plate, in fixed plate
Hole is equipped with, fixing bolt is connected with annealed copper wire through hole, and one end of the elbow-type head connecting rod is equipped with internal thread, passes through rotation
To achieve the purpose that to connect with switchgear elbow-type head connecting rod.Two fixing nuts are which is provided with, have bearing between fixing nut,
Terminal plate is fixedly connected with the bearing race of the bearing is cylindrical, the terminal plate is equipped with bolt hole, and connection bolt passes through spiral shell
Keyhole is fixedly connected with the other end of annealed copper wire, and the end of thread of elbow-type head connecting rod is connected with insulating bar.
One end of the insulating bar is equipped with internal thread, and the other end is cone-shaped end.
The beneficial effects of the utility model are：Compared with prior art, the utility model is rational in infrastructure, convenient and practical, leads to
Cross and dismountable elbow-type head connecting rod is set in one end of insulating bar, elbow-type head connecting rod connects with grounded probe annealed copper wire
Connect, when in use can be as needed, the elbow-type head of elbow-type head connecting rod and switchgear is installed or removed, the work(being grounded
Can, it is easy to operate, achieve good using effect.The Novel connecting ground wire has modern design, practical function, easy to carry etc.
Advantage, can effectively solve such as cable distribution box elbow head that current power distribution network cable run runs into can not effective grounding ask
Topic, can reach improve distribution network reliability and lifting good service to a certain extent.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
To make the purpose of this utility model, technical solution and advantage clearer, below with reference to this specification attached drawing pair
The utility model is described in further detail.
Embodiment 1：As shown in Figure 1, a kind of cable elbow-shaped head ground wire, it is connected including grounded probe 1 with elbow-type head
Bar 6, one end of the grounded probe 1 is taper, and the side of the other end is fixedly connected with fixed plate 2, and hole is equipped with fixed plate
3, fixing bolt 11 is connected with annealed copper wire 4 through hole 3, and the end surface of the elbow-type head connecting rod 6 has screw thread, which is provided with two
A fixing nut 7, there is bearing 8 between fixing nut 7, is fixedly connected with terminal plate 12, institute on the bearing race of the bearing 8 is cylindrical
State terminal plate 12 and be equipped with bolt hole 5, connection bolt 13 is fixedly connected through bolt hole 5 with the other end of annealed copper wire 4, elbow-type head
The end of thread of connecting rod 6 is connected with insulating bar 10.By setting dismountable elbow in one end of insulating bar 10
Type head connecting rod 6, elbow-type head connecting rod 6 are connected with the annealed copper wire 4 of grounded probe 1, and grounded probe 1 is connected with the ground wire at scene,
When in use can be as needed, insulating bar 10 is connected with the elbow-type head of switchgear, then by elbow-type head connecting rod 6 and absolutely
Edge operation lever 10 installs or removes, and is grounded the connection or disconnection of line, easy to operate.
Further, one end of insulating bar 10 is equipped with internal thread, and the other end is cone-shaped end, can very easily be inserted
Enter onto the elbow-type head of switchgear, the function being grounded.
Further, 10kV switchgears need to be laid down during in-site installation（Without switching cable distribution box）Elbow-type head after block up
The Novel connecting ground wire elbow-type head connecting rod 6, is then connected and tightens fixing nut 7 by lid with elbow-type head.
Part is not described in detail for the utility model, is the known technology of those skilled in the art of the present technique.Finally illustrate, with
Upper embodiment is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although with reference to preferred embodiment to the utility model
