Description

technical field [0001] The invention belongs to the technical field of precision measurement, and in particular relates to a method and device for intelligently detecting parameters of each layer of a fully automatic cable. Background technique [0002] The insulation structure of general cables is mainly composed of conductor shielding layer, insulating layer, insulating shielding layer and semiconductor shielding layer. If the insulation thickness of the cable is lower than the standard or the eccentricity exceeds the standard, it will seriously affect the performance of the cable, and even endanger the safety of the power grid, resulting in property loss and casualties. [0003] At present, there are many manual operations in the method of measuring the thickness of cable insulation. Manually fix the cable slice on the pressing plate, manually adjust the position of the cable slice, and then determine the thinnest thickness of the cable slice according to the scale of the...

AI Technical Summary

Problems solved by technology

[0005] 1. Manual measurement steps are complicated, requiring manual operations including clamping cable slices, adjusting positions, judging with the naked eye and finding the thinnest point, and reading multiple measurement points. The measurement process is time-consuming and labor-intensive, and the process is complicated and inefficient

[0006] 2. Manual calculation is complex, with many calculation items and a large amount of calculation, which is prone to calculation errors

[0007] 3. Corresponding devices are required for measurement. When measuring certain types of cable slices, it is often necessary to use a magnifying glass or a projector with a magnification of at least 10 times as a measuring device. It is also necessary to read vernier calipers and calibration rulers. The operation is complicated. It takes a long time and has high requirements for testers

[0008] Therefore, the existing cable insulation thickness testing equipment cannot meet the needs of the industry, and technical transformation and upgrading are urgently needed
