Abstract
A pre-twisted wire clamp additionally equipped with rubber liners is fixedly mounted on a conductor and ground wire of an overhead transmission line, so that a damping wire segment of a power transmission line vibration-proof facility is constructed, i.e. a pre-twisted damping wire is constructed. The pre-twisted damping wire is formed by a twisted wire, two hook clamps pressed and connected at two ends of the twisted wire respectively, rubber liners respectively attached to the inner sidewalls of the two hook clamps, and two pre-twisted wires. The wire clamp is practical, simple in structure and low in cost. When in use, the wire clamp is hung on a conductor and ground wire of an overhead transmission line through the hook clamps, and the hook clamps are then fixed to the conductor and ground wire of the overhead transmission line through winding of the pre-twisted wires. After mounting, since tubular structures of legs of the pre-twisted wires naturally wind a lead, gripping forces from the wire clamp evenly act on the lead of the overhead transmission line along the whole mounting length. Moreover, the rubber liners are attached to the inner sidewalls of the hook clamps, so that if the damping wire segment is blown by the wind and covered ice falls, the conductor and ground wire of the transmission line will not be damaged due to moving, driven by swing and greater waving of the twisted wire, of the wire clamp.
Description
Technical field
The utility model relates to a kind of large span power transmission circuit vibrationproof equipment, the top-twisted wire-clip that particularly employing adds rubber packing fixedly mounts in the lead wire and earth wire of overhead transmission line, to build a damping line segment for transmission line vibrationproof facility, i.e. a kind of preformed damping line.
Background technology
Aeolian vibration is the guidewire movement of a kind of high-frequency, little amplitude, its cause is when stable breeze winnowing overhead wire, lee face at overhead wire forms an air-flow vortex of pressing certain frequency variation and alternatively up and down, this air-flow vortex makes overhead wire be subject to the impulsive force of a upper and lower alternation, when the frequency of this impulsive force and the natural frequency of overhead wire equate, to make overhead wire in vertical plane, produce resonance, i.e. aeolian vibration.Aeolian vibration ripple is smooth sea, and node is motionless, and antinode alternatively up and down changes, and its consequence causing will be that disconnected strand of wire, gold utensil and shaft tower member damage, and very person develops into broken string accident by the thigh that breaks.
For general overhead transmission line, common vibration protection mainly contains stockbridge damper, spiral vibration rod etc. is set; And for large overhead crossing engineering, because span is long, electric wire hitch point is high, landform is open, wire tension is large, can make oscillation intensity increase, vibration frequency range broadens, vibration duration increases, this is more low-level with regard to requiring the oscillation intensity of transmission line to be restricted to, and adopts above-mentioned common vibrationproof facility can not achieve the goal; In addition,, for heavy icing area transmission line, due to its special climatic environment condition, also require vibrationproof facility to adapt to the special operation condition that coating ice falling causes electric wire to jump.
On January 27th, 2010, Chinese patent CN201393035Y discloses a tree-like damping wire, by interval, hung in built on stilts lead wire and earth wire, damping line segment for wire vibrationproof forms, described tree type damping line segment is at damping wire wire clamp of the two ends of lace twisted wire difference crimping, described damping wire wire clamp is by wire clip body, the wire clamp metallic channel of inner conductors, be used for covering pressure, the wire clamp gland of clamping wire, the exhibition arm being rotationally connected with wire clamp gland, be installed on the helical spring on wire clamp, for fastening helical spring bolt, nut forms, at described wire clamp gland lid, press, clamping wire, after helical spring on wire clamp is fastened, exhibition arm can embed wire clip body, block described fastening helical spring bolt, nut.Although advantage stable to wire curable grip, that do not get loose that this tree type damping wire has, can meet the vibrationproof requirement of large span power transmission line conductor (comprising power line, ground wire, OPGW optical cable) low frequency and high frequency, but have that damping wire cable clamp structure is complicated, cost is high and the damping wire wire clamp of rigidity to lead wire and earth wire in transmission line resilient clamp, when wind and coating ice falling, lace twisted wire swings and waves and drives wire clamp lead wire and earth wire in transmission line to be caused to the deficiency of damage.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned large span power transmission circuit vibrationproof facility to build equipment---the deficiency of damping line segment; and a kind of employing of overhead transmission line that the particular surroundingss such as large leap, heavy icing area are provided add the top-twisted wire-clip of rubber packing in the lead wire and earth wire of overhead transmission line, fixedly mount, to build the damping line segment of transmission line vibrationproof facility; it is a kind of preformed damping line; to reduce, build vibrationproof facility cost, and farthest protect power transmission line.
The technical scheme in the invention for solving the technical problem is:
The top-twisted wire-clip that a kind of employing adds rubber packing fixedly mounts in the lead wire and earth wire of overhead transmission line, to build the damping line segment of transmission line vibrationproof facility, it is a kind of preformed damping line, it is by a twisted wire, a pair of axial symmetry is crimped on respectively the crotch chuck at these twisted wire two ends and is attached to respectively rubber packing and the two groups of preformed armor rodses formations on two crotch chuck madial walls, the crotch chuck that described axial symmetry is crimped on respectively twisted wire two ends is respectively A to crotch chuck and B to crotch chuck, A forms A to top-twisted wire-clip to crotch chuck and the rubber packing and the one group of preformed armor rods that are attached on its madial wall, B forms B to top-twisted wire-clip to crotch chuck and the rubber packing and the one group of preformed armor rods that are attached on its madial wall, and A to crotch chuck and B to the lateral surface of crotch chuck on equal transversely arranged anti-skidding positioning convex of preformed armor rods that arranges.
Above-mentioned A to crotch chuck and B to the lateral surface of crotch chuck on laterally the anti-skidding positioning convex of preformed armor rods of spread configuration all have 2 at least.
The top-twisted wire-clip that this employing provided by the utility model adds rubber packing fixedly mounts in the lead wire and earth wire of overhead transmission line, to build the damping line segment of transmission line vibrationproof facility, cable clamp structure is simple, practical, cost is low, during use, with crotch chuck, hang in the lead wire and earth wire of overhead transmission line, and then be wound around crotch chuck fixing in the lead wire and earth wire of overhead transmission line by preformed armor rods, the tubular structure forming due to preformed armor rods both legs after installation is wound around wire naturally, wire clamp is evenly distributed on whole installation length the grip force of overhead transmission line lead wire and earth wire, in addition on the madial wall of crotch chuck, attach rubber packing, make this damping line segment provided by the utility model when wind and coating ice falling, twisted wire swings and waving by a larger margin can not caused damage to the lead wire and earth wire of transmission line to the drive of wire clamp.
