摘要
换流变压器是换流站工程中最为重要的设备之一,充当着交流电与直流电之间的变换核心作用。随着直流电压等级从±800 kV提升至±1 100 kV,换流站的高端换流变压器安装体积更大、吨位更重,安装环境的要求更严格,安装工艺的水平也更复杂。本文结合±1 100 kV古泉换流站工程总结提炼了世界上最高电压等级的换流变安装工艺水平和技术要求的新标准,为后续工程积累了经验和树立了标杆。
Converter transformer is one of the most important equipment in converter station engineering. It has acted as the core role of the conversion between AC and DC. With the increase of DC voltage level from ±800 kV to ±1 100 kV, high-end converter transformer has larger volume and heavier tonnage. The converter installation environment requirements are stricter and the installation process is also more complex. This paper summarizes and refines the technology level and technical requirements of converter transformer installation with the highest voltage level in the world based on the project of ±1 100 kV Guquan converter station.
