Abstract
The utility model relates to a device used on a transmission line, in particular to a device for preventing the vibration of the transmission line. The device comprises a line card and a line card fixed bolt and is characterized in that only two line clips are installed on a transmission lead and the lower end of the line card is fixed with a steel-core aluminum strand. The device is characterized by: 1. effectively absorbing the intermediate and high frequency vibration in the breeze vibration of the transmission line without obviously increasing the tension of the transmission line due to the adoption of multi-point hanging; 2. reducing the phenomenon that the strands of the transmission line break with a pre-stranded wire installed on a lead of a connecting section between the line card and the transmission lead; and 3. effectively decreasing the generation of the phenomenon that the strands of the transmission line break with fatigue caused by the breeze vibration by the use combined with an existing vibration-proof hammer in an experiment.
Description
Affiliated technical field
The utility model relates to the device that uses on a kind of high-tension line, particularly a kind of device that prevents the transmission line vibration.
Background technology
At present, the known stockbridge damper of overhead transmission line aeolian vibration that prevents is made up of tup, steel strand wire, connecting rod and wire clamp.Tup is bound up on the two ends of steel strand wire, and wire clamp is clamped power transmission line, and link rod connects steel strand wire and wire clamp.During the power transmission line aeolian vibration, drive the vibration of steel strand wire and tup, the internal damping consumption power transmission line aeolian vibration energy by steel strand wire reaches the purpose that weakens the power transmission line aeolian vibration.But this stockbridge damper has only a hanging point on power transmission line, in order significantly not increase the tension force of power transmission line, the quality of tup is little, the line footpath of steel strand wire is little, length is short, and therefore, the aeolian vibration energy that its internal damping consumes is few, thereby can not weaken the power transmission line aeolian vibration effectively, particularly medium-high frequency vibration.Hanging with on the power transmission line of this stockbridge damper at present still a large amount of phenomenons that tired disconnected thigh takes place.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, and a kind of vibrational energy that can effectively absorb transmission line is provided, and does not significantly increase the transmission line antihunting device of the tension force of transmission line again.
The technical solution of the utility model is: a kind of transmission line antihunting device, comprise ply-yarn drill and ply-yarn drill set bolt, and it is characterized in that on transmission pressure, being equipped with only rare two wire clamps, the lower end of ply-yarn drill is fixed with steel reinforced aluminium conductor.
Above-mentioned ply-yarn drill be two symmetries respectively be with half arc dop up and down, the middle double end ply-yarn drill that links to each other by connecting plate has bolt hole on connecting plate.
On the lead of the contact-segment of lead and ply-yarn drill, preformed armor rods is installed.
Characteristics of the present utility model are: 1, owing to adopt multiple spot to hang, under the situation of not obvious increase transmission line tension force, can effectively absorb the medium-high frequency vibration in the power transmission line aeolian vibration; 2, on the lead of the linkage section of ply-yarn drill and transmission pressure, preformed armor rods has been installed, so just can have been reduced disconnected burst of phenomenon of transmission line; 3, by test, this device is united use with existing stockbridge damper, can effectively reduce transmission line because the generation of the disconnected burst phenomenon of the fatigue that aeolian vibration brought.
Description of drawings
Accompanying drawing 1 is a mounting structure schematic diagram of the present utility model;
Accompanying drawing 2 is the A-A cutaway view of the utility model accompanying drawing 1;
Accompanying drawing 3 is the left view of the utility model accompanying drawing 2.
Embodiment
As shown in Figure 1, 2, 3, at interval four wire clamps 2 are installed on transmission line 1, the distance between each wire clamp is to determine by actual conditions.Ply-yarn drill be two symmetries respectively be with half arc dop up and down, the middle double end ply-yarn drill that links to each other by connecting plate has bolt hole on connecting plate, the upper end of ply-yarn drill is buckled on the transmission line 1, steel reinforced aluminium conductor 4 is put in the lower end, about two buckle after, be fixed by bolt 3.To make a decision a burst phenomenon in order better separating, on lead, preformed armor rods 5 to be installed in the contact-segment of lead and ply-yarn drill.
Claims (3)
