摘要
Abstract
Coaxial cylinder is the basic structure in DC SF6 gas-insulated equipment. The basic research platform of DC SF6 gas-insulation characteristics was developed to study the insulation characteristics of different gap length and gas pressure. Based on these test results, the calculation model of breakdown voltage of SF6 in long length coaxial cylinder gap was established. Besides, the effect of surface roughness, metallic conducting particle and electrode surface area were also researched and analyzed. The calculation model which is obtained from similar non-uniformity of field and surface roughness with DC SF6 gas-insulated equipment can be used for insulation optimization.关键词
