摘要
根据覆冰形成和发展的物理过程,提出了冰灾发展过程的 3 个阶段理论:迎风面覆冰阶段、冰壳覆冰阶段和冰灾阶段,分析了各阶段的特点,并提出了冰冻前调度潮流抗冰和冰冻后利用直流电源融冰的构想。设计了冰灾综合防御框架,并介绍了构成框架的预警信息系统的功能,提出了融冰装置设计的要求和融冰过程中要遵循的 3 个约束条件。
The overview of ice coating disaster on transmission lines can be summerized into 3 stages： Ⅰ, ice accumulating on the windward side of the conductors; Ⅱ, ice sleeve; Ⅲ, ice damage. This paper has analyzed the characteristics of the three stages and the technologies of on-load network de-icing （ONDI） and HVDC-based de-icing to prevent the damage caused by ice accumulation. A framework for ice disaster prevention is designed and the function of the alert information infrastructure is introduced. The de-icer installments, which need to be designed and operated under certain constraint conditions are described at the end of this paper.
