摘要
750kV兰州东和官亭变电站自2004年建设以来,为西北地区750kV超高压输配电系统的建设奠定了基础。运行中发现了部分设备端子尖端放电、噪声大等问题,因此,高海拔地区750kV变电站防晕型金具的研究及应用成为变电站建设的重要环节。针对高海拔地区750kV变电站防电晕、降低噪音进行了可行性研究,通过对变电站电力金具的改进,成功地解决了设备电晕产生的噪音对环境污染和人身伤害,并在西宁750kV变电站得到成功应用,为今后高海拔地区750kV变电站防电晕措施的进一步改进奠定了基础。
Since the construction of 750 kV Lanzhoudong and Guanting substations in 2004, it was laid a foundation for the construction of 750 kV transmission system in the Northwest, but also the problems of discharge and noise were found at the terminals of some operating equipments. It is the important link to research and adopt corona-proof fitting in 750 kV substations in high altitude area. Aiming at reducing noise and preventing corona in 750 kV substations in high altitude area, the feasibility study was carried out, and through the improvement of fittings in substation, environmental pollution and personal injury generated by corona equipment were successfully solved, which is successfully applied in 750 kV Xining substation, and laid a foundation for further improvement of corona-proof measures in 750 kV substation in high altitude area.
