摘　　要：近年来中低压交联聚乙烯(XLPE)电缆的现场局部放电检测技术在国际上得到了快速发展。其中阻尼振荡波下测量电缆的局部放电在中国的电力运行部门得到广泛应用。笔者简述了该方法的测试原理与优缺点,综述了对不同频率振荡波的耐压与局部放电的测试效果及振荡波电压与工频电压下的耐压和局部放电测试结果的等效性以及其对电缆损害的可能性。In recent years,the technology of on-site partial discharge detection of MV and LV cables obtained the rapid development in the world.The method of partial discharge detection of XLPE cables under oscillating wave voltage is widely used in our power systems.This paper describes the principle,advantages and disadvantages of this test method,and reviews the test results of different frequency,the equivalence between oscillating wave voltage and power frequency voltage,and the damage to the cables.
