China has successfully completed the verification for the world’s first deep-earth grounding electrode, according to the state-owned China Southern Power Grid (CSG).
据中国南方电网(CSG)介绍,中国已经成功地完成了世界上第一个深地接地电极的验证工作。
The success marks that China has independently mastered the technologies in the deep-earth grounding electrode, and also a breakthrough in the field of direct-current transmission.
这一成功标志着我国自主掌握了深地接地电极技术,也是直流输电领域的一次突破。
A grounding electrode, a metallic conductor in direct contact with soil, is the passage of current into the earth and a vital part of direct-current transmission system.
接地电极是直接与土壤接触的金属导体,是电流进入大地的通道,是直流输电系统的重要组成部分。
Traditionally, grounding electrodes are horizontally arranged, covering an area of nearly one square kilometer, leading to difficulties in site selection or land acquisition, especially in economically-developed regions.
传统接地电极水平布置,占地面积近1平方公里,选址或征地困难,特别是在经济发达地区。
"This time, we make the horizontal grounding electrode vertical, going down into the earth one kilometer, which both largely saves land resources, and provides a more secure, reliable and environmental friendly operation mode," said Rao Hong, chief technical expert of CSG.
中电集团首席技术专家饶宏表示:“这一次,我们将水平接地电极垂直放置,深入地下一公里,既大大节约了土地资源,又提供了更安全、可靠、环保的运行模式。”
"It brings a new technical plan for the following direct-current project," Rao added.
饶宏补充说:“这为接下来的直流电项目带来了一个新的技术计划。”
The grounding electrode "plays a significant role in China’s west-east electricity transmission project and can ensure the whole system’s normal operation," said Cai Hansheng, a senior technical expert of CSG.
中电集团高级技术专家蔡汉生表示,接地电极“在中国西电东送工程中发挥着重要作用,可以确保整个系统的正常运行”。
