- 为 了 减 轻 金 具 质 量 ，提 升 金 具 的 安 全 裕 度 ， 开展了高强材料金具的研制工作 。 结 果 表 明 ， 在 借 鉴
我 国 ±800 kV 直流和 1 000 kV 交流工程连接金具设计、制造、建设及运行经验基础上，结合输电线路连接金具的特点，
通过材料遴选、三维建模、力学性能、热处理仿真及锻造成型仿真分析、力学性能试验研究，成功研制了基于 ZG30CrMo
材料经过热处理和锻造仿真的轻型化金具，金具可减重 12%，技术经济效益显著。
In order to reduce the weight of fittings and improve the safety margin of fittings, the research and development of high-strength material fittings is carried out. Based on the design, manufacture, construction and operation experience of ±800 kV DC and 1 000 kV AC line project connecting fittings in China, and the characteristics of transmission line connecting fittings, the research on material selection, three-dimensional modeling, mechanical properties, heat treatment process, forging simulation analysis and mechanical property were carried out. As a result, the lightweight fittings based on ZG30CrMo material after heat treatment and forging process have been successfully developed. The weight of fittings can be reduced by 12%, and the technical and economic benefits are remarkable.
