摘要
220 kV及以上超高压变电站内在管型母线上方展放导线一般均采用停役管型母线、拖放式展放新导线,随着电网供电要求的不断提高,迫切需要开展跨越带电管型母线展放导线的研究。提出研制一套适合变电站内跨越带电管型母线展放导线的新工艺。对实施过程中的关键步骤进行了分析,对主要使用的工器具进行了介绍,提出了相应的安全控制措施,以适用变电站内跨带电管型母线放线作业。
In 220 kV and above ultra-high voltage substations,the conductor-putting on the tubular bus usually adopts the method of the drag-drop new conductor-putting with the service bus stopped.With the increasing requirements of the power supply,it is urgently needed to carry out the study of the conductor-putting in the charged crossing of the tubular bus.The new technology that was suitable for the substation conductor-putting in the charged crossing of the tubular bus was proposed and developed.The key steps in the course of implementation were analyzed,and the main tools and apparatus used were introduced,and the corresponding safety measures were proposed to apply to the operation of the substation conductor-putting in the charged crossing of the tubular bus.
