摘要
概述了XLPE电缆的直流耐压试验、超低频耐压试验、振荡波电压试验和变频谐振试验,提出了直流耐压试验存在的问题,对运行过的电缆不再推荐做直流耐压试验,指出了超低频0.1H z耐压试验对XLPE电缆才是可行有效的耐压方法。
The paper summarizes DC withstand voltage test, ultra-low frequency withstand voltage test, oscillation wave voltage test and variable frequency vibration test. Propese the problems of DC withstand voltage test and no longer recommend to do DC withstand voltage test to running cables. It points out that the ultra--low frequency 0. 1 Hz withstand voltage test to XLPE cable is effective withstand voltgae method.
