Abstract

Изобретение касаетс  испытаний на прочность электрических проводов и позвол ет повысить достоверность путем устранени  погрешностей, св занных с неоднородно расположенными микрополост ми изол ционного сло , при контроле проводов с полимерным изол ционным слоем. Провод подвергают разрывной нагрузке. Обрывок провода используют в качестве образца 2, который статически раст гивают грузом 7 и циклически изгибают вокруг стержней 9. В моменты максимального прогиба подают на образец 2 электрическое напр жение. Выдерживают его заданное врем , после чего изгибают образец в обратном направлении. О стойкости провода суд т по количеству перегибов до пробо . 6 ил.The invention concerns tests for the strength of electrical wires and makes it possible to increase the reliability by eliminating errors associated with non-uniformly arranged microcavities of the insulating layer, while monitoring wires with a polymeric insulating layer. The wire is subjected to breaking load. A piece of wire is used as sample 2, which is statically stretched with a load 7 and cyclically bent around the rods 9. At the moments of maximum deflection, electrical voltage is applied to sample 2. Hold it for a specified time, after which the sample is bent in the opposite direction. The resistance of the wire is judged by the number of kinks in the sample. 6 Il.
