Abstract
The invention discloses a kind of ground wire to connect body device, including ground wire, the ground wire are fixedly connected in rock-soil layer, and conductive sol layer is provided with around rock-soil layer and the ground wire length direction.The present invention pours into a mould one layer of conductive sol layer by being imbedded in around rock-soil layer ground wire, the good conductivity of conductive colloidal sol, the contact area of ground wire and rock-soil layer can be greatly improved, so as to which quickly the electric current that thunder and lightning or power transmission line produce is discharged into the earth, avoid the generation for causing security incident, solve the problems, such as that the velocity of discharge existing in the prior art caused by contact area is small is slow and security risk, and the structure also have the characteristics that it is simple in structure, cheap, easy for assemble or unload.
Description
Technical field
The invention belongs to ground wire technical field of transmitting electricity, and in particular to a kind of ground wire connects body device.
Background technology
, it is necessary to which electric pole or steel tower are being connected by ground wire with the earth during grid power transmission, can be allowed by ground wire
The high current produced in thunder and lightning or power transmission line discharge process is discharged into the earth in time, avoids bringing the generation of security risk, existing
Ground wire connection, using ground wire directly buried in rock-soil layer, ground wire connection mode, the contact area of ground wire and rock-soil layer
Small, release current is slow, if being discharged not in time, easily causes the generation of security incident.
The content of the invention
The technical problem to be solved in the present invention is：A kind of ground wire of simple in structure, release current faster, safe is provided
Connector structure.
The technical solution that the present invention takes is：A kind of ground wire connects body device, including ground wire, the ground wire are fixedly connected on
In rock-soil layer, conductive sol layer is provided with around rock-soil layer and the ground wire length direction.
Preferably, above-mentioned conductive sol layer is cylindrical screw structure, its surface is covered with sharp portion, by helical structure with
And sharp portion, the contact area with rock-soil layer can be greatly increased, improves transition electric conductivity, meanwhile, also improve anticreep
Effect, improves connection reliability.
Preferably, above-mentioned ground wire surface is covered with spherical salient point, on the one hand spherical salient point plays increase conductive contact area,
On the other hand, anticreep is played the role of.
Preferably, above-mentioned conductive sol layer wall thickness is 50 ~ 80mm, and depth is 500 ~ 800mm, can be ensured big in ground wire
Electric current is promptly discharged into the earth, it is blocked up can cause to manufacture it is of high cost, it is excessively thin that electric current rate of release can be caused slow.
Beneficial effects of the present invention：Compared with prior art, the present invention pours into a mould one by being imbedded in around rock-soil layer ground wire
The conductive sol layer of layer, the good conductivity of conductive colloidal sol, can greatly improve the contact area of ground wire and rock-soil layer, so as to fast
The electric current for producing thunder and lightning or power transmission line of speed is discharged into the earth, avoids the generation for causing security incident, is efficiently solved existing
Have present in technology because of the velocity of discharge slowly and the problem of security risk caused by contact area is small, and the structure also has and ties
The characteristics of structure is simple, cheap, easy for assemble or unload.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
In figure, 1- ground wires, 2- conduction sol layers, 3- rock-soil layers.
Embodiment
Below in conjunction with the accompanying drawings and invention is described further in specific embodiment.
As shown in Figure 1, a kind of ground wire connection body device, including ground wire 1, the ground wire 1 are fixedly connected in rock-soil layer 3,
It is provided with conductive sol layer 2 around 1 length direction of the rock-soil layer 3 and ground wire, during installation, ground wire 1 is first placed, in ground wire 1
Surrounding interspaces in advance, enters to improve contact area by pouring into a mould conductive 2 material of sol layer, the present invention is by being imbedded in ground
The conductive sol layer of one layer of cast, the good conductivity of conductive colloidal sol around layer ground wire, can greatly improve connecing for ground wire and rock-soil layer
Contacting surface is accumulated, and so as to which quickly the electric current that thunder and lightning or power transmission line produce is discharged into the earth, avoids causing security incident
Occur, solve the problems, such as that the velocity of discharge existing in the prior art caused by contact area is small is slow and security risk,
And the structure also has the characteristics that simple in structure, cheap, easy for assemble or unload.
1 surface of ground wire is covered with spherical salient point, on the one hand spherical salient point plays increase conductive contact area, on the other hand,
Play the role of anticreep.
Preferably, above-mentioned conductive sol layer 2 is cylindrical screw structure, its surface is covered with sharp portion, passes through helical structure
And sharp portion, the contact area with rock-soil layer can be greatly increased, improves transition electric conductivity, meanwhile, also improve anticreep
Effect, improve connection reliability.
Preferably, above-mentioned conductive 2 wall thickness of sol layer is 50 ~ 80mm, and depth is 500 ~ 800mm, can be ensured in ground wire
High current is promptly discharged into the earth, it is blocked up can cause to manufacture it is of high cost, it is excessively thin that electric current rate of release can be caused slow.
The above description is merely a specific embodiment, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention, therefore, protection scope of the present invention should be based on the protection scope of the described claims.
