摘　　要：导线对地及交叉跨越距离对工程造价影响较大,是线路设计的关键技术原则之一。为确定溪洛渡送电广东±500 kV双回线路导线对地及交叉跨越距离,首先确定导线对地及交叉跨越距离的主要原则,然后分析了线路的电气绝缘强度,拟定电磁环境及其规范、建议限值标准,最后根据国内外设计经验和相关规程,计算分析了线路工程对地及交叉跨越最小间隙距离,为工程设计提供了依据。The clearance of conductor to ground and crossed facilities have a great impact on engineering cost,so it is one ol the key technical principles in transmission line design.In order to determine the clearances of conductor to ground and crossed facilities of Xiluodu-Guangdong 500 kV double circuit transmission line,the paper defines the main principles first.Then,the paper analyzes the electrical insulation strength of the line,and studies out the electromagnetic environment limits.Finally,according to domestic and overseas experience in the design and related procedures,this paper calculates and analyzes the clearances of conductor to ground and crossed facilities.
