The strain fitting string for the large-section ground wire of the large-span line constructed by the utility model can meet the load requirement of the hanging wire of the large-section ground wire, reduce the difficulty of hanging the wire of the strain fitting string, improve the safe reliability of the line operation and ensure the long-term safe and stable operation of electric power facilities.
Description
Technical Field
The utility model relates to the field of transmission line accessories, in particular to a strain fitting string for a large-span large-section ground wire.
Background
With the increase of the transmission capacity of a high-voltage transmission line, the section of a ground wire of a large-span line is increased day by day, and with the increase of the span distance across a river, the breaking force of the ground wire adopted by the large-span line is higher and higher, the requirement on the load grade of a tension-resistant hardware string is higher and higher, when the large-span ground wire adopts the ground wire with the large section, no related string type exists at present, the galloping hazard of the large-span line is particularly serious, and the operation safety of the large-tension large-section large-span line cannot be guaranteed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of overcoming the defects of the prior art and provides a strain fitting string for a large-span large-section ground wire, which is safe, reliable and convenient to install.
The utility model solves the technical problem by adopting the technical scheme that the strain hardware string for the large-span large-section ground wire comprises a hardware string body adopting a single-hanging-point single-connection string structure, wherein the hardware string body comprises a trunnion hanging plate, a first U-shaped hanging ring, a DB adjusting plate, a parallel hanging plate, a PT adjusting plate, a traction plate, a second U-shaped hanging ring and a strain clamp which are sequentially connected, the lower end of the strain clamp is sequentially connected with a grounding metal wire and an equipment wire clamp, and the grounding metal wire and the equipment wire clamp form a grounding wire.
Furthermore, the strain clamp adopts a hydraulic clamp and is used for crimping a large-span large-section ground wire.
Further, the length of the grounding metal wire is 2.0 m-2.5 m.
The strain fitting string for the large-section ground wire of the large-span line constructed by the utility model can meet the load requirement of the hanging wire of the large-section ground wire, reduce the difficulty of hanging the wire of the strain fitting string, improve the safe reliability of the line operation and ensure the long-term safe and stable operation of electric power facilities.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
In the figure: 1. the device comprises a trunnion hanging plate, 2 parts of a first U-shaped hanging ring, 3 parts of a DB adjusting plate, 4 parts of a parallel hanging plate, 5 parts of a PT adjusting plate, 6 parts of a traction plate, 7 parts of a second U-shaped hanging ring, 8 parts of a strain clamp, 9 parts of a grounding metal wire and 10 parts of a device wire clamp.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Referring to the attached drawing 1, this embodiment includes the gold utensil cluster body, the gold utensil cluster body adopts single string structure of hanging a little simply, including 1 trunnion link plate 1, 2 first U type link 2, 1 DB adjusting plate 3, 1 parallel link plate 4, 1 PT adjusting plate 5, 1 traction plate 6, 2 second U type link 7, 1 strain clamp 8 that connect gradually, terminal strain clamp 8 is used for the anchor to stride across big cross-section ground wire greatly.
The lower end of the strain clamp 8 is sequentially connected with 1 grounding metal wire 9 and 1 equipment clamp 10, the grounding metal wire 9 and the equipment clamp 10 form a grounding wire, the large-span large-section grounding wire is electrically connected with the grounding of a tower, and the discharge of the lightning to the ground is completed.
The trunnion hanging plate 1 is used as a hanging point hardware fitting and is hung on a cross arm of an iron tower.
The traction plate 6 arranged in the embodiment is convenient for construction of wire traction and wire tensioning. The strain clamp 8 is of a hydraulic type and is used for crimping a large-span large-section ground wire.
The length of the grounding wire 9 is preferably 2.0m to 2.5 m.
The strain fitting string for the large-section ground wire of the large-span line constructed by the utility model can meet the load requirement of the hanging wire of the large-section ground wire, reduce the difficulty of hanging the wire of the strain fitting string, improve the safe reliability of the line operation and ensure the long-term safe and stable operation of electric power facilities.
Various modifications and variations of the present invention may be made by those skilled in the art, and they are still within the scope of the present invention, provided they are within the scope of the claims of the present invention and their equivalents.
What is not described in detail in the specification is prior art that is well known to those skilled in the art.
