Abstract
The invention discloses a reinforced wire connection device and relates to a wire connection hardware fitting. The current-carrying capability of a connection tube is reinforced and a resistance and the loss at the connection position are also greatly reduced. Wires are abutted by a compression joint tube; a reinforcing preformed armour rod is wound and coated outside the wires and the compression joint tube; the reinforcing preformed armour rod is of a helical shape; the helical turning direction of the reinforcing preformed armour rod is the same with the turning direction of the wires; the length of the reinforcing preformed armour rod is 1.5 to 10 times of the length of the compression joint tube; the two parts at both ends of the reinforcing preformed armour rod, which exceed the compression joint tube, have equal lengths; a first helical pitch of the part of the reinforcing preformed armour rod, which corresponds to the compression joint tube, has the same length with the compression joint tube; and the lengths of second helical pitches of the two parts of the reinforcing preformed armour rod, which exceed the compression joint tube, are 5 to 50 percent of the length of the first helical pitch. In the invention, a single-layer preformed armour rod structure is adopted; and the position at the middle part of the reinforced wire connection device, which is contacted with the compression joint tube, is stranded, so that the pitch length of the reinforced wire connection device is approximate to the length of the compression joint tube and the reinforced wire connection device is convenient to install. For improving the anti-corona capability, the end of the preformed armour rod can also be subjected to special treatment, for example, the end of the preformed armour rod is made into a smooth hemisphere or duckbill shape.
Description
Technical field
The present invention relates to a kind of lead gold utensil that continues, particularly a kind of preformed lead splicing sleeve strengthens connection device.
Background technology
Using number to dote on very much big splicing sleeve on the power overhead network, adopting hydraulic pressure or pincers to press technology, layering continues respectively to the steel core part and the aluminium lamination part of steel reinforced aluminium conductor.Its drawback is: 1. the handshaking procedure more complicated of constructing; Need special crimping apparatus; And effect is installed receives operating personnel's artificial factor to a great extent, be prone to 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 phenomenon that temperature is gone up and down 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.
Summary of the invention
The present invention is directed to 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 the intensity that continues of splicing sleeve simultaneously, make the heavier-duty lead connection device of its breakdown strength that is not less than lead.
Technical scheme of the present invention is: comprise aluminium hydraulic pressed connecting pipe and reinforcement preformed armor rods; Said aluminium hydraulic pressed connecting pipe docks said lead; Said reinforcement preformed armor rods twines, wraps outside lead and aluminium hydraulic pressed connecting pipe, said reinforcement preformed armor rods twist, rotary orientation is identical with said lead rotation direction; The 1.5-10 that said reinforcement preformed armor rods length is aluminium hydraulic pressed connecting pipe times, two parts length that said 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 said reinforcement preformed armor rods is consistent with aluminium hydraulic pressed connecting pipe length, and said two exceed screw pitch two partly is the 5-50% of screw pitch one.
Said lead is a steel reinforced aluminium conductor, also is provided with the splicing sleeve that is used for the crimping steel core in the said aluminium hydraulic pressed connecting pipe.
The present invention 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 let 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.

Embodiment
The present invention is shown in Fig. 1-8: comprise aluminium hydraulic pressed connecting pipe 1 and reinforcement preformed armor rods 2; Said aluminium hydraulic pressed connecting pipe 1 docks said lead; Said reinforcement preformed armor rods 2 twines, wraps outside lead and aluminium hydraulic pressed connecting pipe 1, said reinforcement preformed armor rods 2 twist, rotary orientation is identical with said lead rotation direction; The 1.5-10 that said reinforcement preformed armor rods 2 length are aluminium hydraulic pressed connecting pipe 1 times, two parts length that said reinforcement preformed armor rods 2 two ends exceed aluminium hydraulic pressed connecting pipe 1 is identical; Screw pitch one l of said reinforcement preformed armor rods 2 corresponding aluminium hydraulic pressed connecting pipe 1 parts
