Description
Technical field
The present invention relates to AC Substation engineering field, more particularly to a kind of dual lead device clamp.
Background technology
At present, China have become in the world operation with establish diplomatic relations stream engineering it is most, capacity is maximum, the longest transmission of electricity of circuit
Big country.Substation is the important component in power transmission engineering, stand in largely employ dual lead device clamp extraction wire
Connection mode.As voltage class is continuously improved, wire gauge is increasing, is complicated across mode, to the strong of conducting wire gold utensil
Degree requirement is stringenter.In China some areas, especially northwest region, due to extreme natural environments such as strong wind, sleet, frosts
Influence, often occur dual lead device clamp weld fracture, spalling situation, it is often necessary to interruption maintenance, replace gold utensil,
Carry out secondary construction.
Traditional dual lead device clamp is welded using bushing type, and aluminium hydraulic pressed connecting pipe is sleeved on the outside of double division cylinder ends and is welded
It connects, in actual motion, external force is conducted by conducting wire to aluminium hydraulic pressed connecting pipe, and the position that is stressed directly of aluminium hydraulic pressed connecting pipe with weld seam fixed point distance is non-
The sum of length of area and double division cylinder ends is crimped, the arm of force is longer, and torque increases, and the practical stress born of weld seam is amplified,
The risk of weld cracking increases；Former dual lead device clamp can only determine installation site and side at the scene because of construction process requirement
Bore leakage hole, construction trouble again backward；Due to having certain gap between device clamp aluminium hydraulic pressed connecting pipe and double division cylinder ends, press
Ponding in taking over cannot be emptied by leakage hole completely, and ponding is endured cold expansion under arctic weather, is generated inside gold utensil
Larger stress, the easy spalling of weld seam, influences gold utensil service life.The many disadvantages of the prior art lead to interior dual lead device line of standing
Usually occurs the problem of commissure cracking, spalling in folder actual motion, maintenance cost is high, and repair is frequent, is unfavorable for the peace of power grid
Row for the national games.
Invention content
In view of the shortcomings of the prior art, the present invention provides, one kind is simple in structure, intensity is high, stress is good, no
Easy ponding spalling, the dual lead device clamp for being easy to construction.
To achieve these goals, the present invention uses following technical scheme：
A kind of dual lead device clamp, including wire clip body and aluminium hydraulic pressed connecting pipe, the aluminium hydraulic pressed connecting pipe uses interpolation with wire clip body
Formula connects.
Preferably, the aluminium hydraulic pressed connecting pipe is connect with wire clip body using interpolation type welding manner.
Preferably, the wire clip body includes terminal plate and a U-typed part, and the both ends of the U-typed part are respectively equipped with
One hollow cylinder for being used for grafting aluminium hydraulic pressed connecting pipe.
Preferably, the hollow cylinder inner diameter is fitted close with crimping pipe outside diameter, ensures that aluminium hydraulic pressed connecting pipe can not side after being inserted into
To waving.
Preferably, combination of the hollow-core construction of the hollow cylinder for column and cone structure, the cone structure position
In bottom, the cone structure is connected with the scupper of hollow cylinder bottom.
Preferably, the aluminium hydraulic pressed connecting pipe and wire clip body are aluminum alloy material.
Preferably, the U-typed part includes straightway and an even hollow cylinder, the straightway and hollow cylinder it
Between be respectively equipped with a reinforcing rib.
Preferably, the angle of the reinforcing rib and the straightway is 25 ° -35 °.
Present invention has the advantages that：The present invention is welded using aluminium hydraulic pressed connecting pipe interpolation type, is effectively increased bonding area, is improved
Weld seam integral strength, it is ensured that do not destroyed under the conditions of the harsh climates such as strong wind, sleet.After bonding area increase, wire clamp
Whole current capacity improve, caused by effectivelying prevent current carrying area deficiency gold utensil temperature rise it is excessively high the problem of.In actual motion, outside
Power is conducted by conducting wire to aluminium hydraulic pressed connecting pipe, aluminium hydraulic pressed connecting pipe be stressed directly position and weld seam fixed point distance be only one section of crimpless area away from
From the arm of force is short, and stress is good, and wire clamp is enable not snapped under the effect of higher external force, ensures longtime running；Dual lead device
The material of wire clamp is changed to aluminium alloy by the fine aluminium of traditional scheme, and tension and anti-bending strength increase substantially.Leakage hole can be opened
It is processed in gold utensil factory in the underface of gold utensil ponding position and directly, the process for reducing construction site, improves installation effect
Rate, and it effectively prevent gold utensil ponding spalling.
