Abstract
The invention discloses a clearance type strain clamp for conducting wires. The strain clamp comprises an aluminium pipe, a steel anchor body, a drainage board and a jumper wire board, wherein the drainage board and the aluminium pipe are welded through an anchor ear in 360 degrees; the steel anchor body penetrates through the drainage board and is mounted in the aluminium pipe; the drainage board and the jumper wire board are fixedly connected through a bolt; a drainage tube is mounted in the jumper wire board; and a conducting wire is mounted in the drainage tube. The invention improves the stress condition of the aluminium pipe when the load of the jumper wire is transferred to the aluminium pipe and avoids partial force bearing of the aluminium pipe wall; the electrifying area between the drainage board and the aluminium pipe body is enlarged; and the construction is facilitated, the power cut time is shortened, and the pass of heavy-current is not influenced.
Description
Technical field
The present invention relates to a kind of strain clamp of clearance type lead.
Background technology
Along with growing continuously and fast of Chinese national economy, soaring significantly to the demand of electric power, the expansion in electricity needs market has promoted electric power transmission network and has promoted and spurred development of electric power industry.Power grid construction is just towards extra-high pressure, big capacity developer conveying direction at present.Under this kind situation, newly-built transmission line is more and more, and conductor cross-section is increasing, and land resource that takies and physical resources also will get more and more, and conflict has taken place this relative with physical resources present situation in short supply with China's land resource.Therefore, currently press for a kind of novel over capacity lead and replace traditional steel reinforced aluminium conductor.
Super heat-resisting clearance type capacity-improving conducting wires is that heat-resisting aluminium alloy is made one of serial lead of conductor, but its feature be mechanically stressed be steel strand wire, Ampereconductors is at aluminium alloy stranded conductor.Because it is gapped between steel strand wire and the superalloy twisted wire, fill the solid lubrication grease in the gap, the aluminium alloy stranded conductor layer can be free to slide at steel strand surface, can make overhead wire at 70 ° of C of 210 ° of C(ordinary steel core aluminum stranded wires) safe operation down, still can guarantee less electric wire sag this moment, (building) the over the ground required distance when satisfying the various operating mode of lead.Major advantage is that the current carrying capacity of conductor in same cross section can reach about 2 times.
Summary of the invention
The object of the present invention is to provide a kind of strain clamp of clearance type lead.The present invention has improved the wire jumper Load Transfer and has given the aluminum pipe force-bearing situation, has avoided aluminum pipe wall local pressure; And the energising area increases between drainage plate and the aluminum pipe body; Secondly convenient construction shortens interruption duration, does not influence big electric current again and passes through.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of strain clamp of clearance type lead comprises aluminum pipe, steel anchor body, drainage plate, jumper wire board; Wherein 360 ° of anchor ear welding of drainage plate and aluminum pipe; Steel anchor body is passed in the aluminum pipe; Drainage plate and jumper wire board are bolted to connection; Crimping drainage thread in the aluminum pipe of jumper wire board; Crimping lead in the described drainage tube.
Described steel anchor body is forged by steel loop, threaded body one successively and forms.
Described jumper wire board is provided with 2.
Described lead is the clearance type lead.
Beneficial effect of the present invention is: 360 ° of anchor ear welding of (1) drainage plate and aluminum pipe, and improve the wire jumper Load Transfer and given the aluminum pipe force-bearing situation, avoided aluminum pipe wall local pressure; (2) drainage plate and Al pipe butt welding area calculate with circumference, and the energising area increases between drainage plate and the aluminum pipe body; (3) drainage tube is made 2, and its dull and stereotyped end clamps with the drainage plate front and back and installs, and selects 2 super heat-resisting clearance type lead wire jumpers in parallel, and convenient construction shortens interruption duration, does not influence big electric current again and passes through.In old transmission line capacity-increasing transformation, be economic, quick and effective scheme.
