摘要
Abstract
The ±660 kV DC power transmission pilot project from Ningdong to Shandong is the first ±660 kV DC power transmission project in the world. Based on the engineering practice of this project, detailed experimental conditions for the research are determined, and experimental research on the safety distance for live-line working of ±660 kV DC power transmission line under various operating conditions is performed. On the basis of experiments, firstly, the overvoltage multiple occurred in ±660 kV DC power transmission line is determined by theoretical calculation; secondly, according to discharge characteristics of safety distances for various positions where the live-line working is carried out and considering the calculated overvoltage multiple, the minimum safety distance and minimum combined spacing, via which the operators enter into the equipotential working position, for ±660 kV DC power transmission line located at the area with the altitude lower than 2 000 m are calculated. Results of this research can offer reference and technical support for live-line working carried out on ±660 kV DC power transmission.关键词
