Abstract

The invention relates to the technical field of conductor material detection, and discloses a coiled power cable conductor material detection system and method. The system comprises a resistance measuring module, a temperature measuring module and a central processing unit connected with the resistance measuring module and the temperature measuring module. The resistance measuring module is used for acquiring the conductor resistance of a measured cable, and the temperature measuring module is used for acquiring the environment temperature of the measured cable. The central processing unit is configured to acquire the conductor resistance of the tested cable at two groups of different temperatures, and determine whether the conductor material of the tested cable is pure metal according to the first temperature, the first conductor resistance, the second temperature, the second conductor resistance, the temperature coefficient of the resistance and the linear expansion temperature coefficient. The system provided by the invention can automatically judge the quality of the whole disc of tested cable, and effectively prevents cable manufacturers from having the behavior of sneak work and material.

Description

technical field [0001] The present application relates to the technical field of conductor material detection, and in particular to a system and method for detecting conductor material of coiled power cables. Background technique [0002] Because power cable products are closely related to the lives of consumers, their quality and safety directly affect the personal and property safety of consumers. High-voltage and extra-high-voltage cables in power cables are highly valued, and the products meet the requirements of technical specifications. High-voltage and extra-high-voltage cable products have strict inspection methods from design, production, delivery and on-site completion. The products also meet the requirements of technical specifications, and there are few problems. [0003] Low-voltage and medium-voltage cables receive little attention, the process is relatively simple, and the number of new cable suppliers is increasing rapidly. There are some prominent problems ...
