Abstract

The invention discloses a method for evaluating the electrical performance recovery degree of a self-repairing material. The method comprises the following steps: acquiring the resistivity of a plurality of test samples after the self-repairing material is cut by adopting a high-resistance method; cutting the test sample by adopting cutting treatment, and obtaining the resistivity of a plurality of self-healing test samples; obtaining the average value of the resistivity of the plurality of test samples and the percentage of the average value of the resistivity of the plurality of self-healing test samples to determine the self-healing efficiency; and if the self-healing efficiency meets a preset evaluation condition, determining that the electrical performance self-repairing capability of the self-repairing material is qualified. According to the method, the resistivity of the cutting material and the resistivity of the self-healing material are obtained, the outliers are further removed, the self-healing efficiency is obtained, the self-repairing capacity is further evaluated, the self-healing capacity of the material is effectively judged, and the judgment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a method for evaluating the recovery degree of electrical properties of self-healing materials. Background technique [0002] Self-healing cable insulation material is an emerging material. The existing cable repair mainly relies on simple technologies such as heat welding and heat shrinkable tubes. It is necessary to use positioning technology to check the faulty cable from the end and find the fault point, and also need to excavate the covering soil, Removing stitches and power outages consumes manpower and material resources. When further evaluating the self-healing ability of the material, it will lead to uninterrupted operations, resulting in low evaluation efficiency and low accuracy. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a method for evaluating the recovery degree of electrical properties of self-healing materials,...
