摘要
当前用于XLPE电缆检测现场试验方法主要包括直流电压法、超低频(0.1 Hz)电压法、阻尼振荡波电压法,对各种方法的特点进行了论述,并介绍了不同试验方法等效性研究的发展概况。最后,在上述研究方法的基础上,结合实际经验,提出后续研究的内容及方法。
At prezent, the three main methods for XLPE cables on-site testing are dc withstand test, very low frequency test and damped alternating voltage test. The characteristics of the various methods are discussed and an overview of the development of the equivalence of these methods is presented. Finally, in terms of the practical problems, the content and method for further study were proposed based on the achievements of the previous study.
