Optimization Design for External Insulation of Electric Equipment of Traction Power Supply System in Plateau and High Altitude Area
高海拔环境条件对电气设备外绝缘有很大影响,国内外尚无海拔高度超过3 000 m电气化铁路相关设计经验.从某高原高海拔地区工程实际出发,开展了高海拔地区牵引变电系统外绝缘优化设计,通过对海拔校正因数的计算,确定了牵引变电所内外配电装置的空气绝缘间隙和高压电气设备耐受电压；讨论了绝缘子特征指数的选取,提出了绝缘泄漏距离修正方案,计算了悬式绝缘子外绝缘泄漏距离和绝缘子片数、支持绝缘子和电气设备外绝缘泄漏距离等参数.该线路开通后牵引变电设备保证了可靠和安…查看全部>>
The influence of plateau and high altitude environment on electric equipment external-insulation is serious, while the design experience of electrified railway with the elevation more than 3000m is lack. In this paper, with the practical needs of a certain actual project, the optimizaLion design of electric equipment external-insulation in traction power supply system in high altitude area was carried out. And then, through the calculation of altitude correc…查看全部>>
