Description
Technical field:
The utility model is used for the electric power system overhead transmission line and relates in particular to the special-purpose strain clamp of strengthening of a kind of carbon fiber composite core wire.
Background technology:
Strain clamp is to be used for overhead transmission line, and lead fixed on the strain insulator string that the non-rectilinear bar is set foot on, is played the anchoring effect, and strain clamp will bear the pulling force of lead.At present, China's overhead transmission line conductor adopts steel reinforced aluminium conductor mostly.The strain clamp that is used for this lead adopts steel anchor mode crimping lead steel core and then the steel anchor is inserted aluminum pipe crimping and tension-resisting clip aluminum pipe and 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 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, and that this lead has is in light weight, do not expand after being heated, and 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, conventional be used for the steel reinforced aluminium conductor strain clamp and can not be applied to carbon fiber composite core wire.
Summary of the invention
The purpose of this utility model provides a kind of carbon fiber composite core conductor strain clamp, it is 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 the special-purpose reinforced carbon fiber composite core wire that internal structure can reuse connects the fixed strain clamp of anchoring.
Technical solution of the present utility model is the steel anchor at existing strain clamp, drainage plate, on the basis of drainage wire clamp, the utility model particularly has the strain clamp main body, described strain clamp main body is the pipe of a hollow, be provided with bushing pipe in the leading portion radially in the pipe of hollow, be provided with the clamping device of carbon fiber composite core wire with bushing pipe place separated by a distance, the steel anchor inserts with the clamping device screw thread from the back segment port and fixes, can be connected simultaneously with the lead composite core that clamping device fix, at the pairing strain clamp body of the step part of bushing pipe and steel anchor through hydraulic pressure and crimping is fixed in aggregates.
The clamping device of above-described carbon fiber composite core wire is made up of with the external conical sleeve with conical internal cavity the inner conical drogue of a center radial direction through hole.
Inner conical drogue described in the utility model center radial direction through hole diameter is less than the carbon fiber complex core external diameter, the inner conical drogue profile is conical, 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 major part holds setting to the microcephaly, but described gap has with a certain distance from little head end.
Above-described external conical sleeve is that a center is a conical cavity and profile is cylindrical pipe, and one the big end of diameter of the conical cavity in the external conical sleeve is provided with internal thread.
Steel anchor described in the utility model is that an end is the shaft of a ring, the described shaft other end is provided with and the identical fixing external screw thread of the internal thread of external conical sleeve, the end face of termination is provided with the lead that the concaves chamber of continuing, and locates to be provided with the stressed step of aluminum pipe crimping between ring and external screw thread.
Above-described bushing pipe one end is provided with tapering.
Described bushing pipe front end stretches out the strain clamp main body.
Operation principle of the present utility model is with one section of the aluminum conductor strip off of carbon fiber composite core wire, the carbon fiber complex core that will expose passes bushing pipe, strain clamp main body from left to right successively until the other end that passes the strain clamp body, penetrate the central through hole of external conical sleeve, inner conical drogue more successively, carbon fiber complex core is clamped by external conical sleeve and inner conical drogue.Again external conical sleeve and inner conical drogue integral body are pulled back to the strain clamp body.The male end of steel anchor injected in the strain clamp body from right to left screw with external conical sleeve.Bushing pipe should should leave the deformation that produces when certain interval is used for the bushing pipe crimping with external conical sleeve and inner conical drogue.Adopting hydraulic method to carry out crimping in the pairing strain clamp body exterior of the step part of bushing pipe and steel anchor then becomes one.With bolt strain clamp is connected with the drainage wire clamp at last and can finishes installation.Under the tension force effect of lead, inner conical drogue moves in external conical sleeve and carbon fiber complex core is held tighter, guarantees that lead is had enough grips, and its grip is not less than and is mounted carbon fiber composite core wire and calculates 95% of pull-off force.
The utility model has the advantages that, it is 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 the special-purpose reinforced carbon fiber composite core wire that internal structure can reuse connects the strain clamp of anchoring.
