基于10 kV交联聚乙烯(XLPE)电缆试样,在阻尼振荡波(DAC)作用下,研究了20~300 Hz频率内含针尖缺陷电缆绝缘的击穿特性随频率的变化规律.结果表明:在38.2~173.2 Hz内,DAC击穿电压随频率的升高而增大,在173.2 Hz处击穿电压达到峰值约为24 kV;在173.2~300 Hz内,DAC击穿电压随频率的升高而降低.
The variation of breakdown characteristic versus frequency of 10 kV XLPE cable with needle defect was studied in a frequency range of 38.2~173.2 Hz under damped AC(DAC) voltage. The results show that when the frequency ranges from 38.2 Hz to 173.2 Hz, the breakdown voltage under DAC in-creases with the increase of frequency, and the breakdown voltage attains maximum at about 173.2 Hz. When the frequency is in the range of 173.2~300 Hz, the breakdown voltage under DAC decreases with the increase of frequency.
