Description
Technical field:
The utility model is used for the electric power system overhead transmission line, relates in particular to a kind of gold utensil that continues of carbon fiber composite core wire special use.
Background technology:
The lead gold utensil that continues is to use in the overhead power transmission engineering, two section leads is continued, to satisfy the gold utensil of lead interconnect function between two section leads.Its connection must be satisfied the electric conductivity requirement, promptly satisfies the gold utensil resistance that continues and is not more than resistance requirement between the equal length lead, and the gold utensil temperature rise that continues is not higher than the lead temperature rise.Also must satisfy the intensity that continues of lead, the intensity of the gold utensil that promptly continues is not less than 95% of lead pull-off force.At present, China's overhead transmission line conductor adopts steel reinforced aluminium conductor mostly.The strain clamp that is used for this lead adopts the steel core butt joint or has a common boundary, and re-uses the steel pipe crimping, satisfying the steel core requirement of strength, and then the steel anchor is inserted aluminum pipe crimping and tension-resisting clip aluminum pipe becomes one, and is used to carry lead stretching force and conduction.This class lead can satisfy conduction and tension force requirement at present, but because steel reinforced aluminium conductor has big magnetic loss, it is big to move line loss for a long time; When raise by conductor temperature, circuit degree of speeding increases, and is unfavorable for increasing the transmission of electricity of line span and high temperature.
In recent years, a kind of carbon fiber composite core wire of appearance began to be applied to overhead transmission line and began to replace conventional steel reinforced aluminium conductor.The carbon fiber complex core of carbon fiber composite core wire has replaced the steel core of steel reinforced aluminium conductor, that this lead has is in light weight, intensity is high, do not expand after being heated, degree of speeding is little after using on the high temperature transmission line, reduces advantages such as line steel tower quantity thereby help increasing line span.But because carbon fiber complex core is fragile material, do not have bending strength, its tension and anti-extrusion ability are lower than steel core, and the conventional steel reinforced aluminium conductor gold utensil that continues that is used for can not be applied to carbon fiber composite core wire.
Summary of the invention
The purpose of this utility model provides the energy-conservation lead of a kind of carbon fiber complex core gold utensil that continues, be used to connect the internal layer tension structure combination of carbon fiber complex core, do not need when mounted the carbon fiber complex core crimping, do not damage carbon fiber complex core, simple to operate, do not get loose after the installation, grip is strong, and internal structure can reuse.
Technical solution of the present utility model is that the contact tube main body is arranged, described contact tube main body is a tubulose, radial midpoint place in described pipe is provided with the double end connecting bolt, the double end connecting bolt is connected with all symmetrically arranged carbon fiber complex core clamping device in both sides respectively, described clamping device front end is provided with the filling bushing pipe, and the head end of filling bushing pipe stretches out outside the contact tube main body.
Be so that installation clamping square in the middle of the above double end connecting bolt, two ends are threaded portions, and screw thread is the setting of positive inverse taper thread, and described two ends end is provided with the lead that the concaves chamber of continuing.
Carbon fiber complex core clamping device described in the utility model is made up of with the external conical sleeve with conical internal cavity the inner conical drogue of a center radial direction through hole.
The above inner conical drogue center radial direction through hole diameter is less than carbon fiber complex core external diameter inner conical drogue, profile is coniform, two interspaces that the useful line of inner conical drogue cuts out, article one, be to hold extension to the setting of stub end direction by the cone microcephaly, but described gap has with a certain distance from stub end, another interspace is extended by the cone stub end holds setting to the microcephaly, but described gap has with a certain distance from little head end.
External conical sleeve described in the utility model is that a center is a conical cavity and profile is the pipe of cylinder, and one the big end of diameter of the conical cavity in the external conical sleeve is provided with internal thread part.
The tapering of above-described inner conical drogue outside is identical with external conical sleeve inner chamber tapering.
The internal thread of locating to be provided with that threaded portion, double end connecting bolt two ends described in the utility model and outer cone sleeve pipe inner conical chamber diameter are big adapts.
Above-described filling bushing pipe internal diameter is greater than wire diameter, and its length is consistent with contact tube main body crimping partial-length.
Separated by a distance between filling pipe described in the utility model and the described clamping device.
Operation principle of the present utility model is that two sections carbon fiber composite core wires insert from the filling bushing pipe at contact tube main body two ends respectively, described lead inside is composite core, the outside is an aluminum conductor, aluminum conductor fills bushing pipe with aluminium matter and aluminium matter contact tube main body conduction is connected, the inner composite core of described lead penetrates inner conical drogue, and inner cone is nested with in the external conical sleeve, and inner conical drogue is subjected to external conical sleeve pressure after the distortion of two interspace places, can guarantee certain combinational gap, the described composite core of stronger clamping.The composite core termination is stretched into lead that double end connecting bolt end face concaves always and is continued in the chamber, is right after with the double end connecting bolt, thereby realizes that two section leads conduction connects.Double end connecting bolt and external conical sleeve stub end internal thread screw, lift external conical sleeve thereby can tighten up, further reach the pressure of adjusting to inner conical drogue, guarantee that inner conical drogue clamps described composite core, filling interspaces between bushing pipe and the clamping device in advance is to compress in aggregates for penetrating lead and assembling back to filling the residing contact tube main part of bushing pipe hydraulic pressure.
Advantage of the present invention: be used to connect the internal layer tension structure combination of carbon fiber complex core, do not need when mounted the carbon fiber complex core crimping is not damaged carbon fiber complex core, simple to operate.Do not get loose after the installation, grip is strong, internal structure such as can reuse at advantage.
