摘要
变电站一键顺控技术可将传统的就地倒闸操作转变为远程一键顺控模式,在安全、时效及节省人力等方面效果突出,因此常规变电站的一键顺控改造工程尤为重要。在一键顺控改造过程中,关键技术难点主要集中在隔离开关的分合闸位置“双确认”、开关柜手车及二次空开的电动化改造、压板和空开的监视与管理技术这3个方面。文章针对这3大技术难点,依据实际改造工程中的实践经验,提出了相应的解决方案,对常规变电站的一键顺控改造具有一定的参考价值和指导意义。
The one-key sequence control technology in substations can transform traditional local switching operations into remote one-stop sequential control modes,with significant effects in terms of safety,efficiency,and manpower saving.Therefore,the one-key sequential control renovation project in conventional substations is particularly important.In the process of one key sequential control transformation,the key technical difficulties mainly focus on three aspects:the"double confirmation"of the opening and closing positions of the isolation switch,the electrification transformation of the switchgear handcart and secondary air switch,and the monitoring and management technology of the pressure plate and air switch.This article focuses on these three major technical difficulties and proposes corresponding solutions based on practical experience in renovation projects.It has certain reference value and guiding significance for the one key sequential control renovation of conventional substations.
