Embodiment Construction

[0021] Such as figure 1 As shown, the anchor 1 is mainly composed of the internal thread of the special component, which is connected in turn with the inner cone and external thread core sleeve 3, the inner cone and external thread core sleeve 3 is connected to the outer cone elastic core 4, and the outer cone elastic core 4 is internally connected to JRLX / T (ACCC) carbon fiber wire 6, then hydraulically connected to the hollow through hole, a tubular sleeve 2 with a disc 201 on the outside of one end, the end of the sleeve 2 is connected to the bushing 5 and JRLX / T (ACCC) carbon fiber wire insulation layer ) form the overall structure.

[0022] Such as figure 2 As shown, the internal thread pull anchor 1 of the special-shaped member is prepared by connecting a flat pull ring 102 with a long through hole 103 on the left side of the round stopper 101, and connecting 1 to 8 telescopic grooves 104 and half of the internal thread 105 on the right side. Hollow cylinder.

Abstract

The invention provides a strain clamp for JRLX / T carbon fiber leads, relates to a strain clamp for connecting, fixing and tensioning the JRLX / T (ACCC) carbon fiber leads on a pole tower in an overhead electric transmission and transformation circuit, is classified in H02G7 / 02, and relates to electric power fittings arranged in the electric transmission and transformation circuit, namely the technical field of devices for adjusting and keeping mechanical tension. The strain clamp comprises an internal thread pull anchor, a sleeve, an inner-cone external thread core sleeve, an outer-cone elastic clamp core, a bush, and the like. The strain clamp is mainly characterized in that the internal thread pull anchor is connected with the inner-cone external thread core sleeve the middle of which the outer-cone elastic clamp core passes through, a lead composite core passes through the interior of the outer-cone elastic clamp core, the outer-cone elastic clamp core is automatically clamped with the inner-cone external thread core sleeve through a radial acting force to lock the lead composite core, and the JRLX / T (ACCC) carbon fiber leads are connected and fixed on the pole tower through hydraulic pressure and the like. The strain clamp has the advantages of novel structure, good guide performance, strong stability, stable holding power, low cost, convenience for mounting and constructing, low labor intensity, and the like.

Description

technical field [0001] The invention relates to a strain clamp for connecting, fixing and tensioning JRLX / T (ACCC) carbon fiber conductors in overhead power transmission lines and on towers of substations. Classified in H02G7 / 02, it relates to the technical field of power fittings installed in power transmission and transformation lines, that is, devices for adjusting and maintaining mechanical tension. Background technique [0002] The strain clamp is a power fitting for connecting, fixing and tensioning the wires in the overhead transmission line and on the tower of the substation. At present, domestic power transmission lines all use steel core, aluminum stranded wire, and steel cored aluminum stranded wire. First, it is prone to hysteresis damage and consumes electric energy; After explosive crimping, the metallographic phase is changed due to the strong impact force, the mechanical strength is reduced, and the construction is unsafe. At present, JRLX / T (ACCC) carbon f...
