Description

Technical Field

[0001] The invention relates to the technical field of auxiliary devices for making cable heads, in particular to a multifunctional bracket for making cable heads.

[0002] During the initial deployment or repair of power cables, it is inevitable to make cable joints or intermediate joints. The cable head is the weakest point of cable insulation. When the manufacturing process and quality of the cable head do not meet the standards, there will inevitably be defects (air gaps, bubbles and impurities, etc.) inside. The defects will lead to uneven distribution of the electric field, and the potential hidden dangers will be reflected in the future operation. When the defects are repeatedly subjected to overvoltage shocks, when the field strength reaches a certain value, dendritic discharge (tree-like fine channels and discharge marks) will be formed on the insulation, causing deterioration and local discharge. After a long period of cumulative effect, this local discharge will gradually expand the degradation channel, reduce the insulation performance and form a penetrating channel, leading to accidents. By dissecting and piercing the cable, traces of groove-shaped discharge paths and some voids (decomposition gas) can be found, which is the result of dendrite discharge degradation. The cable head is generally made of local materials. The cable is placed on a fixed structure or tool box. One or more people fix the end of the cable, and another person makes the cable head. This requires the cooperation of multiple people to operate, resulting in low work efficiency. At the same time, manual fixation is used, which has problems such as unstable operation, poor safety, and the inability to guarantee the quality of the cable head.

[0003] The published patent CN 102593765 A provides a cable head manufacturing bracket, which adopts an H-shaped bracket composed of two columns and a crossbeam with a retractable structure. The length and height of the H-shaped bracket are adjusted according to the on-site conditions, and the cable ends are fixed on the top of the two columns to manufacture the cable head. However, the stability of the bracket in this technical solution is obviously not as good as the triangular bracket. The H-shaped bracket is unstable when in use and is easy to tilt under the action of external force, and the cable is easy to slide, which increases the difficulty of manufacturing and the quality of cable head manufacturing cannot be guaranteed.

[0004] Therefore, it is necessary to develop a multifunctional bracket for making cable heads which is stable in operation, easy to carry and easy to promote, so as to reduce the fatigue of operators during the production of cable heads, improve work efficiency and ensure the production quality of cable heads.
