Abstract
A strengthened lead splicing device relates to a lead splicing hardware tool, strengthens current carrying capacity of splicing tubes and greatly reduces resistance and loss of splicing positions. Leads are in butt joint via a crimping tube, a strengthening pre-twisting wire is wound and wrapped outside the leads and the crimping tube and is spiral, the spiral turning direction of the strengthening pre-twisting wire is identical to the turning direction of the leads, the strengthening pre-twisting wire is 1.5 times to 10 times longer than the crimping tube, the lengths of two portions, which exceed the crimping tube, of the strengthening pre-twisting wire are identical, a spiral pitch I, which corresponds to the crimping tube, of the strengthening pre-twisting wire is identical to the length of the crimping tube, spiral pitches II of the two exceeding portions of the strengthening pre-twisting wire are larger than the spiral pitch I by 5% to 50%. The strengthened lead splicing device adopts a single-layered pre-twisting wire structure, the middle of the single-layered pre-twisting wire structure and a contact portion of the crimping tube are stranded, so that the pitch length of the single-layered pre-twisting wire structure is close to the length of the crimping pipe, thereby bringing convenience for installation. In order to increase anti-corona capacity, the ends of the pre-twisting wire can be in special treatment, for example, the ends of the pre-twisting wire are made into smooth semi-spherical type or duckbilled type.
Description
Technical field
The utility model relates to a kind of lead gold utensil that continues, and particularly a kind of preformed lead splicing sleeve strengthens connection device.
Background technology
Using the very huge splicing sleeve of number on the power overhead network, adopting hydraulic pressure or pincers pressure technology, layering continues respectively to the steel core part and the aluminium lamination part of steel reinforced aluminium conductor.Its drawback is: 1. Shi Gong handshaking procedure more complicated, need special crimping apparatus, and effect is installed is subjected to operating personnel's artificial factor to a great extent, easily cause physical damnification (mechanical damage), cause taking place lead strand crack conditions lead; 2. power circuit service life often requires to surpass 30 years, and run duration forms thermal cycle owing to the instability of circuit operating load produces the temperature phenomenon of lifting repeatedly, makes adapting electric voltage increase, thereby has increased line loss; The mechanical strength that continues simultaneously descends, and the safe operation of transmission line is constituted a threat to.
The utility model content
The utility model is at above problem, provide a kind of and can solve the deficiency of aforementioned crimp type splicing sleeve existence in service effectively, both strengthened the current capacity of splicing sleeve, greatly reduce the resistance and the loss at the place that continues again, can also strengthen simultaneously the intensity that continues of splicing sleeve, make the heavier-duty lead connection device of its breakdown strength that is not less than lead.
The technical solution of the utility model is: comprise aluminium hydraulic pressed connecting pipe and reinforcement preformed armor rods, described aluminium hydraulic pressed connecting pipe docks described lead, described reinforcement preformed armor rods twines, wraps outside lead and aluminium hydraulic pressed connecting pipe, described reinforcement preformed armor rods twist, rotary orientation is identical with described lead rotation direction, the 1.5-10 that described reinforcement preformed armor rods length is aluminium hydraulic pressed connecting pipe times, two parts length that described reinforcement preformed armor rods two ends exceed aluminium hydraulic pressed connecting pipe is identical; The screw pitch one of the corresponding aluminium hydraulic pressed connecting pipe part of described reinforcement preformed armor rods is consistent with aluminium hydraulic pressed connecting pipe length, and described two screw pitches two that exceed part are the 5-50% of screw pitch one.
Described lead is a steel reinforced aluminium conductor, also is provided with the splicing sleeve that is used for the crimping steel core in the described aluminium hydraulic pressed connecting pipe.
The utility model adopts individual layer preformed armor rods structure, and middle part and aluminium hydraulic pressed connecting pipe contact site make its pitch length close with aluminium hydraulic pressed connecting pipe length through stranded, the convenient installation.The prefabricated shaping of preformed armor rods has conduction sand behind its inner surface additional, to improve electric conductivity; Preformed armor rods adopts the aluminum-alloy wire manufacturing, with convenience and the high conduction performance that utilizes its processing; Preformed armor rods is the monofilament state during payment, makes things convenient for the scene to install and use, and can allow preformed armor rods be wrapped in aluminium hydraulic pressed connecting pipe and lead outside equably.In order to improve anti-corona ability, special processing also can be carried out in the termination of preformed armor rods, such as being made into smooth dome-type or Duckbill type.
