摘要
绝缘电阻是电线电缆最基本的电气性能之一,它反映了电缆在正常工作状态下的电气绝缘性能,是电缆绝缘特性的重要指标。通过实例计算电缆70℃绝缘电阻的合成不确定度及扩展不确定度,并提出了绝缘电阻测量的注意事项。
Insulation resistance is one of the basic electrical properties of wires and cables, and it is an important quality feature of the tested object. Many factors of the uncertainty measurement of 70 insulation resistance are considered, and the uncertainty of insulation resistance is given also. This work is a useful guide for insulation resist-ance test.
