In the invention, the preformed beam structure with single preformed layer and a plurality of parallel reinforced preformed armor rods is adopted, thus the high-efficiency enhanced type lead wire continuity device is convenient for installation. Compared with winding of single reinforced preformed armor rod, the invention has the advantage that the field installation and usage in the invention are more convenient.
Description
Technical field
The present invention relates to a kind of wire-connection gold utensil, particularly a kind of preformed lead splicing sleeve strengthens connection device.
Background technology
Power overhead network uses the splicing sleeve that number is very huge, adopt hydraulic pressure or pincers pressure technology, layering continues respectively to the steel core part of steel reinforced aluminium conductor and aluminium lamination part.Its drawback is: 1. the handshaking procedure more complicated of construction, need special crimping apparatus, and the impact that effect is subject to operating personnel's human factor is to a great extent installed, easily cause the physical damnification (mechanical damage) to wire, cause wire strand crack conditions occurs; 2. power circuit service life often requires more than 30 years, and run duration produces the phenomenon that temperature is elevated repeatedly due to the instability of circuit operating load, forms thermal cycle, adapting electric voltage is increased, thus adds line loss; The mechanical strength simultaneously continued declines, and constitutes a threat to the safe operation of transmission line.
Summary of the invention
The present invention is directed to above problem, provide a kind of deficiency that effectively can solve existence in the operation of aforementioned crimp type splicing sleeve, both the current capacity of splicing sleeve had been strengthened, greatly reduce again resistance and the loss at the place that continues, the intensity that continues of splicing sleeve can also be strengthened simultaneously, it is made to be not less than the breakdown strength of wire, and the high-efficient reinforced lead splicing device that installation effectiveness is higher.
Technical scheme of the present invention is: comprise aluminium hydraulic pressed connecting pipe and reinforcement preformed armor rods, described wire docks by described aluminium hydraulic pressed connecting pipe, described reinforcement preformed armor rods is wound around, wraps outside wire and aluminium hydraulic pressed connecting pipe, reinforcement preformed armor rods described in 2-5 root is single to be connected as one side by side, again coiling form preformed son bundle twist; The rotary orientation of described preformed son bundle is identical with described wire rotation direction, and described preformed sub-Shu Changdu is 1.5-10 times of aluminium hydraulic pressed connecting pipe, and two parts length that described preformed son bundle 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 preformed son bundle is consistent with aluminium hydraulic pressed connecting pipe length, and the two-part screw pitch two that described preformed son bundle two ends exceed aluminium hydraulic pressed connecting pipe is the 5-50% of screw pitch one.
Described wire is steel reinforced aluminium conductor, is also provided with the splicing sleeve for crimping steel core in described aluminium hydraulic pressed connecting pipe.
The present invention adopts that individual layer is preformed, the preformed sub-binding structure of many bunchys arranged side by side, and middle part and aluminium hydraulic pressed connecting pipe contact site, through stranded, make its pitch length and aluminium hydraulic pressed connecting pipe similar length, is convenient to install.The prefabricated shaping of preformed armor rods, has conduction sand after its inner surface additional, to improve electric conductivity; Preformed armor rods adopts aluminum-alloy wire manufacture, the convenience of processing to utilize it and high conduction performance; During payment, preformed armor rods is multifibres juxtaposition, is wound around relative to monofilament, and more convenient in-site installation uses, and preformed sub-synnema can be allowed to be wrapped in aluminium hydraulic pressed connecting pipe and wire outside equably.In order to improve anti-corona ability, special processing also can be carried out in the termination of preformed armor rods, is such as made into smooth dome-type or Duckbill type.
