Clamping device and cable main insulation layer reaction force cone machining equipment
Technical Field
The utility model relates to a cable centre gripping equipment field especially relates to a clamping device and cable main insulation layer reaction force awl processing equipment.
Background
The high-voltage direct current transmission has the advantages of high transmission efficiency and low energy consumption. Because of its more economical characteristics than ac transmission, it is widely used for long-distance or ultra-long-distance transmission. And the length of the jointless manufacture is 10km at most due to the limitation of the high voltage cable manufacturing process. When ultra-long distance transmission is to be achieved, a single cable joint needs to be processed so that a plurality of cables are spliced together. At the joint of the cable, because of two different insulation materials, namely the cable body insulation and the additional insulation, the electric field distribution of the cable is different from that of the cable body, so that a certain potential difference, namely axial field intensity, namely axial stress is generated between two adjacent points on the same layer of insulation. Therefore, the insulation layer near the conductor connection end is usually cut into a conical surface, i.e. a reaction force cone, and then wrapped around the build-up insulation, so as to form a stress conical surface at the two ends of the build-up insulation. The potential distribution of the insulating surface is changed, the effect of uniform electric field is achieved, and the safety of the joint is ensured.
In the processing of the reaction cone, it is generally necessary to clamp the cable and then process the cable with a cutting tool to form the reaction cone. When the existing clamping equipment is used for clamping cables, the existing clamping equipment cannot be suitable for cables with various diameters, is difficult to operate, poor in clamping effect and incapable of stably clamping the cables, and the yield of the processed reaction force cone is low.
