架空地线与导线之间存在电磁感应，由此带来架空地线电能损耗问题。对架空地线节能接地技术进行系统研究，提出架空地线感应电压的控制原则，区分单回、多回线路提出架空地线节能接地方式以及地线分段节距计算公式。提出地线绝缘子及间隙选型要求，给出标准大气压以及不同海拔、温度、湿度条件下间隙距离参数，对冰区绝缘子还提出了覆冰绝缘配置和直流融冰技术要求。提出多种光纤复合地线（optical fiber composite overhead ground wire， OPGW）节能接续方案，并介绍了OPGW常用金具。提出的架空地线节能接地技术已在广东电网冰区、非冰区线路中实际应用。

Becaused of the electromagnetic induction between overhead ground wires and conductors,there is a huge power loss of overhead ground wires.Systematic study was carried out on the energy-saving grounding technology for overhead ground wires.The control principle of induced voltage of overhead ground wires was proposed,and different energy-saving grounding modes and calculation formula of segmented distance for overhead ground wires were presented according to single-circuit or double-circuit.Then,this paper proposed the selection requirements of ground wire insulator and its parallel gaps,and also introduced in detail how to choose the gap distance under standard atmospheric pressure,as well as different altitude,temperature and humidity conditions.For ground wire insulators in the icing area,this paper also proposed technical requirements of insulation configuration and DC ice melting.Finally,this paper suggested a variety of energy-saving splicing schemes of OPGW,and also introduced the common OPGW fittings.The proposed energy-saving grounding technology of overhead ground wires has been applied in Guangdong Power Grid,including overhead transmission lines in icing zone and non-icing zone.
