摘要
以贵州电网为例,介绍了贵州电网采用的直流融冰技术的原理和系统,分析了所安装的直流融冰装置并介绍了贵州电网实施的大电流温升试验以及4次现场融冰情况。给出直流融冰技术带来的经济效益和社会效益,证明了直流融冰技术在贵州电网的应用是成功的。
Taking Guizhou Power Grid as example, the paper introduces the DC de-icing principles and system utilized in Guizhou Power Grid. Equipments installed in Guizhou Power Grid are analyzed. Temperature rising tests of transmission lines with large DC current by Guizhou Power Grid are given, together with 4 de-icing operations in Guizhou. The economic effect and social effect brought by DC de-icing technology are discussed. It is considered that the application of DC de-icing technology in Guizhou Power Grid is successful.
