Abstract
The utility model provides a spacer that conductor spacer for preformed armor rod, it is sticked together by the freedom section in bank at both ends and the whole curved U -shaped form of making of mid portion winding heliciform preformed armor rods together constitutes, and the freedom section in bank at both ends sticks together and constitutes the section of gripping of conductor spacer, wholly is spirally wound on by two wires of spaced, and the supporting is done in the mid portion winding together between two wires. Its processing technology is simple and convenient, and the steady quality, and the uniformity is good, it can with preformed armor rods to lead, the static compressive stress of ground wire uniformly the dispersion to the great region, improve lead, the ground wire goes up abominable ambient stress with gold utensil looks the contact region, make lead, the ground wire avoids destructive vibration and fatigue, has superior fatigue resistance ability, its simple installation is swift, and bare -handed installation does not need the mounting tool, has improved the installation rate of gold utensil and the efficiency of hand labor, the great improvement of spacer rigidity is favorable to resisting horizontal direction pressure, keeps by the interval of two wires of spaced.
Description
Technical field
The utility model relates to a kind of conductor spacer for preformed armor rod of power circuit Anti-galloping.
Background technology
In overhead transmission line, often occur colliding between wire and rub, the problem such as relative motion, gentle breeze vibration occur between wire, all can cause damage in various degree to cable.In overhead transmission line, often use rigidity conductor spacer and damping conductor spacer to prevent the appearance of this problem at present, but rigidity conductor spacer and damping conductor spacer generally adopt aluminium alloy to cast, because aluminium alloy casting is higher to technological requirements such as temperature control and heat treatments, therefore very easily casting flaw is caused, especially latent defect not easily finds, can bring potential safety hazard after installing and using to transmission line; In addition, in overhead transmission line, lead, ground wire normally bears one of the most concentrated parts of various load, rigidity conductor spacer and damping conductor spacer is used to be easy to produce stressed centrostigma, the dynamic bending that stressed centrostigma near zone is subject to and static buckling stress maximum, therefore it very easily makes to lead, ground wire sustains damage when fatigue; All need to use specific purpose tool when also having rigidity conductor spacer and damping conductor spacer to install, and need periodic maintenance, intricate operation and lavishing labor on.Within on 09 29th, 2010, Chinese patent CN201594722U discloses a kind of conductor spacer for preformed armor rod, comprises U-shaped preformed armor rods, and two extension arms of described U-shaped preformed armor rods are holding section; Described holding section is spirality; Two holding sections of described U-shaped preformed armor rods are wrapped in two respectively by the sub-conductor at interval; The middle part of described U-shaped preformed armor rods is spacer.Spacer due to it is the parallel Side by side groupings of sub-thread preformed armor rods; rigidity is poor; stressedly namely occur that spacer preformed armor rods is out of shape; change the spacing between wire; the effect of interval cable can not be played; therefore, the current urgently conductor spacer for preformed armor rod that a kind of spacer rigidity is stronger protects cable better.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency overcoming above-mentioned existing conductor spacer for preformed armor rod, and provides the conductor spacer for preformed armor rod that a kind of spacer rigidity is stronger.
The technical scheme in the invention for solving the technical problem is: a kind of conductor spacer for preformed armor rod, it is in a row sticked together by the free segment at two ends and the helical form preformed armor rods Integral bending that mid portion is intertwined is made U-shape and formed, the free segment at two ends in a row sticks together and forms the holding section of conductor spacer, entirety is spirally wrapped around by two of interval wires, and mid portion is intertwined the spacer done between two wires and support.
This conductor spacer for preformed armor rod provided by the utility model adopts the prefabricated cold forming of high-strength aluminum alloy line, and processing technology is easy, and steady quality, consistency is good; Preformed armor rods is wrapped on wire by it, preformed armor rods is longer, can by preformed armor rods to leading, be distributed on larger region the static pressure stress equilibrium of ground wire, avoid the problem that compression joint type gold utensil produces stress concentration point, obvious reduction is led, Static and dynamic stress on ground wire, improve lead, ground wire contacts ambient stress severe on region with gold utensil, make to lead, ground wire from destructive vibration and fatigue, have superior anti-fatigue performance; Its simple installation is quick, and free-hand installation does not need erecting tools, can adjust after visual inspection installation quality, and the installation stopping to cause because installer uses instrument is inconsistent, improves the installation rate of gold utensil and the efficiency of hand labor; Its spacer adopts the mode being carried out the bottom of some strands of U-shaped preformed armor rodses being wound around, and substantially increases the rigidity of spacer, is conducive to opposing horizontal direction pressure, keeps by the spacing of two of interval wires.
