A method for controlling the bending radius of cables

Abstract

The invention discloses a cable bending radius control method, which uses a cable bending radius controller to select the corresponding scale required by the pull rope on the cable bending radius controller on the support rod according to the minimum bending radius required by the cable to be bent value, and then connect one end of the rope to the pull ring at the scale value, and the other end is at the distance between the pull ring at the scale value of the support rod and the bendable rod to ensure that the length is equal to the corresponding scale value of the support rod When the length of the support rod between the pull ring and the bendable rod is connected to the end of the bendable rod, then use the arc of the bendable rod to compare with the bent cable, and you can clearly see the bend Whether the cable meets the minimum standard requirements. In this way, the cable insulation will not be damaged, the operating life of the cable will be extended, the safe and stable operation of the power grid will be improved, and the investment in power grid construction will also be reduced.

Description

technical field [0001] The invention relates to a cable bending device, in particular to a cable bending radius controller and a cable bending radius control method. Background technique [0002] With the continuous deepening of urban cableization, the number of power grid cables in various regions is increasing day by day, and the cable occupies a dominant position in the power grid. The safety of its operation will directly affect the safe and stable operation of the power grid. Therefore, it is urgent to improve the quality of cable engineering. The focus of future project construction. The cable bending radius is an important index to ensure the insulation performance of the cable laying construction and operation. If the bending radius of the cable is less than the specified value during the laying construction or operation, it will directly lead to the destruction of its structure, directly affect its life, and eventually lead to insulation breakdown. , leading to saf...

The cable bending radius is an important index to ensure the insulation performance of the cable laying construction and operation. If the bending radius of the cable is less than the specified value during the laying construction or operation, it will directly lead to the destruction of its structure, directly affect its life, and eventually lead to insulation breakdown. , leading to safety and quality accidents, affecting the safe and stable operation of the power grid

[0003] 1. Due to urban planning and historical reasons, the size of cable wells in many places is generally small. How to reasonably arrange the position of cables and control the minimum bending radius of cables is a major problem in engineering construction.

[0004] 2. Due to various factors, the construction of cable projects is now undertaken by the cooperative team. Due to the low professional quality of the cooperative team members and driven by economic interests, etc., the construction of the project is often only about the progress, not about the quality, which leads to Many potential safety and quality hazards, such as: random placement of cables, hard extrusion of cables into the work well, resulting in the bending radius of the cables reserved for the work well cannot meet the requirements, etc.

Cable bending radius is an important indicator to ensure its insulation performance. Too small bending radius will damage its internal structure and directly affect its life. In severe cases, it will directly lead to insulation breakdown and lead to safety and quality accidents.

[0006] 4. The traditional method of measuring the minimum bending radius of cables is to use visual inspection or tape measure, etc. This method brings large errors, which is easy to cause misjudgment and misjudgment, is not scientific, and is not practical in the process of engineering construction
