Abstract
A composite core energy-saving aluminum wire connecting Clamps, the transition within a central link, linking the extreme left of the left threaded adjustment bolts connecting the left bolt, right left conditioning bolts connecting thread tension sets left, the transition of the pressure to take over the left contacts left Tension sets, left Inner Tension sets a folder left Tension Sandwich, left for the tension Sandwich hollow cone, from the two ends of radial-sharing 120 degrees, and has opened a gap at both ends of the chutes opened, and left Tension sets with Tension core ,Left matching its diameter from coarse to fine, a link connecting the right side of the structure and link structure connecting the same extreme left. The connector clamps simple structure, easy assembly, material selection non-permeable material, do not produce eddy current power loss, it is by adjusting the tension bolts Rotary setst achieve the required torque generated tension Sandwich axial movement to produce radial grip strength, clamping done automatically, tension load will be transmitted to the core from the two ends of composite wire, is the new generation of composite core of a new type of aluminum wire connecting clamps.
Description
Technical field
The present invention relates to fixing, the clamping connector of composite core power cable aluminium stranded conductor in a kind of high pressure overhead power line.
Background technology
At present, domestic transmission line connecting clamp, it fixes, clamps steel reinforced aluminium conductor one is that lead is pegged graft, and the less grafting of contact-making surface is not firm, and lead generates heat easily; The 2nd, aluminum pipe hydraulic pressure, the two ends lead inserts aluminum pipe during installation, and then with the hydraulic tool pressurization, but contact-making surface is less, and grip is not strong; The 3rd, explosion crimping makes wire clamp clamp lead by the powerful impulsive force of the moment of detonating, but because strong wallop changes metallographic, mechanical strength reduces, and it is dangerous to explode.The connecting clamp that uses on the present domestic transmission line all exist install inconvenient, contact-making surface is less, the lead heating, shortcomings such as grip deficiency, mechanical strength reduction, can not be applicable to new material composite core aluminium hinge line fixing, clamp and connect.
Summary of the invention
The objective of the invention is to provide that a kind of contact-making surface is big, grip is strong, composite core aluminium strand energy-saving connecting wire clamp easy for installation, that be suitable for mutually with thermal cycling temperature and tension intensity.
The object of the present invention is achieved like this: by transition conduit, hookup, left and right sides aluminium hydraulic pressed connecting pipe, left and right sides tension force chuck, left and right sides tension force sandwich, the left and right adjusting bolt is formed, there is hookup at the middle part in the transition conduit, the left end left-hand thread of hookup connects a left side and regulates bolt, a left side is regulated the bolt right-hand thread and is connected left tension force chuck, left aluminium hydraulic pressed connecting pipe in the transition conduit contacts left tension force chuck, be with left tension force sandwich in the tension force chuck of a left side, left side tension force sandwich is a hollow cone, radially divide equally 120 degree respectively from two ends, have the clearance groove that does not open at two ends, a left side tension force chuck and left tension force sandwich are complementary, its internal diameter from fine to coarse, the right-hand member right-hand thread of hookup connects right adjusting bolt, the right bolt left-hand thread of regulating connects right tension force chuck, right aluminium hydraulic pressed connecting pipe in the transition conduit contacts right tension force chuck, is with right tension force sandwich in the right tension force chuck, and right tension force sandwich is a hollow cone, radially divide equally 120 degree respectively from two ends, have the clearance groove that does not open at two ends, right tension force chuck and right tension force sandwich are complementary, and its internal diameter is from coarse to fine.
Beneficial effect: in the such scheme, material selection non-permeable material, do not produce the eddy current electric energy loss, it is to screw in moment that the tension force chuck reaches regulation and produce to move axially and make the tension force sandwich produce radially grip by regulating bolt, automatically finish clamping, tension load is sent on the lead of two ends from composite core, and it is simple in structure, assembling is easy, is a kind of novel connecting clamp of composite core aluminum stranded wire of new generation.
