摘　　要：全球能源互联需要连接“一极一道”(即北极和赤道)和各洲大型能源基地,光纤复合架空地线(OPGW)作为电力系统通信的主要通信载体,将遇到西伯利亚、北极等地区的极寒条件。资料显示,在西伯利亚测到的历史最低温度为-70℃,而普通OPGW配套金具仅能保证-40℃以上稳定运行要求。文章通过研究极寒条件下35CrMo合金结构钢OPGW金具产品锻造与热处理工艺,对比了几种处理方案的工艺性能,确定了耐极寒OPGW金具锻造产品热处理和锻造工艺方案。本项研究作为通信解决方案的一部分,保证了极寒地区OPGW的应用。Global energy interconnection needs to connect"one pole together"(i.e.the Arctic and the equator)and large energy bases on all continents.Optical fiber composite overhead ground wire(OPGW)as the main carrier of power system communication will encounter extreme cold conditions in Siberia,the Arctic and other regions.The statistics show that the historic minimum temperature measured in Siberia is–70℃,while ordinary OPGW matching fittings can only guarantee stable operation above–40℃.In this paper,the forging and heat treatment processes of 35CrMo alloy structural steel OPGW metal products under extreme cold conditions are studied,and the technological properties of several treatment schemes are compared.The heat treatment and forging process schemes of the forging products of extreme cold resistant OPGW metal products are determined.As a part of communication solution,this research ensures the application of OPGW in extremely cold areas.
