Abstract

The utility model relates to transmission line damping type shielding failure proof lightning arrester, including a wire clamp fastened with the ground, a damping cushion, a locking bolt, a needle bar rack, a balance weight and a leading needle bar. One end of the leading needle bar is connected with the balance weight into a whole through the needle bar rack. The wire clamp is tightly fixed with a groundwire through the damping cushion. The needle bar rack is tightly fixed and connected with a lower cover of the wire clamp through the damping cushion arranged inside the needle bar rack and is tightly fastened by the locking bolt. The utility model utilizes the mechanism that a needlepoint can generate thunderbolt bow-on pathfinding easily to invert the thunderbolt shielding failure wire into the long jab overhead earth wire to control, according to the modern technology of lightningproof theory and techniques, thus effectively reducing the accident of lightning strike and flashover on the wire of supervoltage and extra-high voltage, and enhancing the level of safe operation of electric fence as well as preventing the groundwire or OPGW optical cable from being hit directly by the lightning current, so as to prevent the wires from striking off by the lightning strike. The utility model also has the advantages of easy production and convenient installation and construction.

Description

Electric transmission line damping twist hit prevention lightning conductor

Technical field

The utility model relates to a kind of annex gold utensil of used for transmission line, is the protection gold utensil class device that prevents overhead transmission line thunderbolt breakdown of conducting wires, particularly a kind of electric transmission line damping twist hit prevention lightning conductor.

Technical background

At present ultra-high-tension power transmission line extra high voltage network particularly because of the lightning conducter shielding was lost efficacy, and causes thunderbolt breakdown of conducting wires rate height, at present in the world with the domestic used for transmission line lightning arrester that does not also have similar this version.This product is practicability and effectiveness both, makes easily again and produces, and also is convenient to installation.

Summary of the invention

The purpose of this utility model shields the failure rate height that lost efficacy for anti-shielding lead because of lightning conducter, a kind of electric transmission line damping twist hit prevention lightning conductor is provided, particularly superhigh pressure and extra high voltage line lost efficacy because of the lightning conducter shielding and caused the high characteristics of thunderbolt breakdown of conducting wires rate the utility model at ultra-high-tension power transmission line, rely on modern lightning protection theory and technology, utilize needle point to be easy to generate head on guide's mechanism of thunder and lightning, being intended to effectively the thunderbolt lead is converted into the direct attack overhead ground wire is controlled, thereby reach the lightning stroke flashover accident that reduces superhigh pressure and extra high voltage line, improve the purpose of electric power netting safe running level, simultaneously also can avoid lightning current directly to hit ground wire or OPGW optical cable, prevent that thunderbolt from causing disconnected strand.The utility model is made easily again and is produced, and also is convenient to installation.

The technical solution of the utility model is:

Electric transmission line damping twist hit prevention lightning conductor, comprise the wire clamp, damping rubber cushion, clamping screw 6, shank hanger 7, balance weight 8 and the guide's shank 9 that are anchored on ground wire, guide's shank 9 one ends are connected one by shank hanger 7 with a balance weight 8, wire clamp is anchored on the ground wire by the damping rubber cushion, the shank hanger is fastenedly connected by built-in damping rubber cushion and wire clamp lower cover, and utilizes fastening bolt 6 that it is fastening.

Described wire clamp is made up of chuck loam cake 1, chuck lower cover 2 and chuck locking pin 3, the chuck upper and lower cover (1 of wire clamp, 2) end links together by chuck locking pin 3, the chuck upper and lower cover (1 of wire clamp, 2) other end is placed horizontal damping rubber cushion 4, and the chuck lower cover 2 of wire clamp and vertical damping rubber cushion 5 are fastening with itself and shank hanger by locking fixing bolt 6.

Angle guide's shank 9 and that horizontal direction forms is between 10～15 °.

The utility model goes for various different-diameter overhead ground wires, wherein contains OPGW optical cable and good conductor ground wire.The utility model is anchored on head-on guide's shank on the ground wire by wire clamp, keeps installation position substantially constant with what guarantee shank when wind lotus and the icing with balance weight, promptly keeps producing thunder and lightning head on guide's direction and the whole performance that possesses the damping vibrationproof.

Particularly superhigh pressure and extra high voltage line lost efficacy because of the lightning conducter shielding and caused the high characteristics of thunderbolt breakdown of conducting wires rate the utility model at ultra-high-tension power transmission line, rely on modern lightning protection theory and technology, utilize needle point to be easy to generate head on guide's mechanism of thunder and lightning, being intended to effectively the thunderbolt lead is converted into the direct attack overhead ground wire is controlled, thereby reach the lightning stroke flashover accident that reduces superhigh pressure and extra high voltage line, improve the purpose of electric power netting safe running level, simultaneously also can avoid lightning current directly to hit ground wire or OPGW optical cable, prevent that thunderbolt from causing disconnected strand.The utility model is made easily again and is produced, and also is convenient to installation.In addition, apply reflectorised paint, have the navigation alarm function, avoid airborne aircraft bump transmission line at positions such as the anti-shielding lightning arrester counterweights of damp type.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

In conjunction with the accompanying drawings the utility model is further described.

It is same as the prior art that present embodiment does not relate to part.

The angle with horizontal direction formation of guide's shank 9 is 15 °.

During concrete enforcement,, which kind of improves, as long as similar lightning-arrest shank etc. is being installed on the ground wire all within the claimed scope of the utility model no matter doing.
