Abstract
The utility model relates to a double-rod type damped anti-shielding-failure lightning rod for a power circuit, which comprises a wire clamp fastened on a ground wire, damping rubber pads, damping rings, a rod rack and guide rods; wherein, the guide rods are symmetrically fixed on both sides of the rod rack; the wire clamp is fastened on the ground wire through the damping rubber pads; the rod rack is integrated with a lower wire clamp cover; and the damping rings are fixed on the rod rack. Utilizing the mechanism that the tips of the rods can easily generate lightning upward guide, the utility model can effectively convert a shielding-failure wire into a direct-struck overhead ground wire to be controlled, thus effectively preventing the shielding-failure wire, greatly reducing the trip-out rate of lightning-striking failure and ensuring the safe operation of a grid, and meanwhile, the utility model also can prevent lightning from directly striking the ground wire or an OPGW optic cable, and prevent strand breaking caused by lightning strike. In particular, the utility model adopts double rods to more effectively enlarge the anti-lightning protection range for a circuit with a single ground wire, and more notably reduce the construction investment of the circuit. The utility model can be easily fabricated and conveniently installed.
Description

Technical background
At present high-voltage electric power circuit 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 rod that does not also have similar this version.
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 power circuit damping two pointer type anti-shock arrester 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 high-voltage electric power circuit, 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 utility model be applicable to 110kV～500kV until 1000kV and ± 800kV transmission line overhead ground wire, the cross section is at 50～250mm
2Steel strand wire, aluminum-cladding stranded wire, good conductor twisted wire or OPGW Optical Fiber composite overhead Ground Wire etc.Especially it is more effective to increase lightning protection at single lightning conducter, and it is more remarkable to reduce the line construction investment.
The technical solution of the utility model is:
Power circuit damping two pointer type anti-shock arrester, comprise the wire clamp, damping rubber cushion, damping ring, shank hanger and the guide's shank that are anchored on ground wire, guide's shank symmetry is fixed on the both sides of shank hanger, wire clamp is anchored on the ground wire by the damping rubber cushion, it is an integral body that shank hanger and wire clamp lower cover link together, and damping ring is fixed on the shank hanger.
Described wire clamp is made up of chuck loam cake, chuck lower cover and chuck locking pin, chuck upper and lower cover one end of wire clamp links together by the chuck locking pin, the chuck upper and lower cover other end of wire clamp is placed the damping rubber cushion, and the chuck lower cover of wire clamp and shank hanger are an integral body.
The crosspointer horizontal symmetrical of guide's shank is distributed in shank hanger both sides, and the angle that guide's shank and horizontal direction form and upwarps between 10～15 °.
Described damping ring is fixed on the shank hanger by the whole cast of steel strand wire, and two damping rings are 30 ° with the ground perpendicular angle separately, and respectively to different directions, one is left, another to the right, the direction of damping ring is vertical with the direction of guide's shank.
The utility model be applicable to 110kV～500kV until 1000kV and ± 800kV transmission line overhead ground wire, the cross section is at 50～250mm
2Steel strand wire, aluminum-cladding stranded wire, good conductor twisted wire or OPGW Optical Fiber composite overhead Ground Wire etc.The utility model is anchored on head-on guide's shank on the ground wire by wire clamp, the shank symmetrical balance is arranged with what guarantee shank and is kept installation position constant substantially when wind lotus and the icing, promptly keep to produce 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 prevent the thunderbolt lead effectively, the lightning fault trip-out rate of Jiang Diing significantly, reduce the lightning stroke flashover accident of superhigh pressure and extra high voltage line, guarantee electric power netting safe running, 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 practicability and effectiveness both, makes easily again and produces, and also is convenient to installation.
