Problems solved by technology

However, in the traditional cable laying construction process, the amount of project funds and the construction management level of the construction personnel are limited. The cable laying only reduces the stress on the cable by installing tension gauges and adding pulleys based on experience, lacking scientific guidance supported by data , the method used cannot really protect the cable, the cable is easily damaged, and the safety is low

Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0016] As described in the background art, in the traditional cable laying construction process, workers only reduce the stress on the cable by installing tension gauges and adding pulleys based on experience during the cable laying process. The inventor found that this way of reducing the force of the cable lacks scientific guidance supported by data. Due to the lack of accurate force analysis, the cable is often dragged during the laying process due to turning, inclination or various other factors. Such reasons ...

Abstract

The invention discloses a cable laying stress analysis method and device. The cable laying stress analysis method comprises the following steps: segmenting discrete points according to cable grounding modes, cable laying modes and cable bending types corresponding to pipeline detection discrete points in a cable laying channel; and carrying out stress analysis calculation on the minimum segment where the discrete point is located according to segment information and the measurement information of the discrete point. Real-time stress analysis of each section of the cable in the cable laying process is achieved, data support is provided for cable laying, a worker laying the cable can adopt a corresponding coping protection means in the laying process according to the stress analysis result, the effect of protecting the cable can be truly achieved, and the safety of the cable in the cable laying process is improved.

Description

technical field [0001] The embodiment of the present invention relates to power system technology, in particular to a method and device for stress analysis of cable laying. Background technique [0002] In recent years, cables have become an important part of transmission and distribution lines. Compared with overhead lines, cables have the characteristics of large available underground space, less susceptible to environmental influences and high reliability, and have been widely used in urban power grids. [0003] In order to standardize infrastructure and relocation projects and improve the efficiency of life cycle management of power grid assets, it is very important to strictly control the quality of cable laying. However, in the traditional cable laying construction process, the amount of project funds and the construction management level of the construction personnel are limited. The cable laying only reduces the stress on the cable by installing tension gauges and a...
