Description

Technical Field

[0002] Cable eccentricity detection mainly involves measuring the eccentricity of the cable insulation layer, which is an important quality control indicator in the power cable manufacturing process; Cable eccentricity, that is, the degree of misalignment between the cable insulation layer and the conductor axis, directly affects the electrical performance and safe use of the cable. Therefore, accurate measurement and control of cable eccentricity is crucial to ensure cable quality and safety. The measurement method of cable eccentricity mainly includes offline detection. Offline detection usually adopts a destructive sampling method, that is, the thickness distribution of the insulation layer is directly measured by cutting the cable insulation layer, and then the eccentricity is calculated. However, in actual measurement, the offline detection method under the existing technology still has the following shortcomings: First, the cable eccentricity offline detection device under the existing technology usually detects the thickness distribution of the cable insulation layer by manually cutting the cable insulation layer, and then calculates the eccentricity, but this method is labor-intensive and inconvenient, and the cable eccentricity offline detection method under the existing technology does not have a convenient automatic cutting detection function; Furthermore, the existing offline detection method for cable eccentricity generates some debris and impurities when cutting the cable insulation layer, and the existing offline detection device for cable eccentricity does not have the function of cleaning these debris and impurities; Therefore, in summary, it is necessary to provide an eccentricity measuring device for cable production.
