Electric power cable tension detection device

Abstract

The invention relates to the technical field of a glass fiber reinforced plastic pipeline, in particular to an electric power cable tension detection device. The electric power cable tension detectiondevice comprises a clamping body, wherein the clamping body comprises an outer ring, a middle ring and an inner ring in coaxial arrangement; a connecting mechanism is arranged between the outer ringand the middle ring; a clamping device used for tightly clamping a cable is arranged between the middle ring and the inner ring; the middle ring and the inner ring relatively rotate and can drive theclamping device to tightly clamp or release the cable; bulge structures which are distributed at equal intervals around the axis of the middle ring and are integrally connected with the middle ring are arranged on the inner wall of the middle ring; gaps are formed between the bulge structures and the inner ring; a self locking mechanism used for preventing the clamping device from rotating in a reverse direction is arranged on an inner groove formed between the two adjacent bulge structures. The cable clamping device has the advantages that the structure is simple; the design is ingenious andreasonable; the preorder preparation time of operators in the work process can be reduced; the work efficiency is improved; the economic pressure of enterprises can also be reduced.

Description

technical field [0001] The invention relates to the field of glass steel pipes, in particular to a power cable tension detection device. Background technique [0002] The power cable is used to transmit and distribute large-scale electric energy in the main line of the power system, and the control cable directly transmits the electric energy from the power distribution point of the power system to the power connection line of various electrical equipment and appliances. Its main feature is to extrude (wind) the insulation layer outside the conductor, twist several cores (corresponding to the phase wire, neutral wire and ground wire of the power system), and then add a sheath layer, such as plastic or rubber sheathed wire and cable. Main technology has drawing, stranded, insulation extruded (wrapped), stranding, armouring, sheath to extrude etc., and the different operation combinations of various products have certain difference. According to the voltage level, power cable...

Problems solved by technology

However, the existing tension detection devices all use pincer clamps to clamp the cables. This clamping method is easy to be rotated by the torsion when the cables are under tension, which is very prone to errors and affects the performance of the cable. Accuracy of cable tension testing data
