浅谈智能变电站母差刀闸位置指示装置研究与应用

Elementary Introduction to the Research and Application of the P osition Indication Device of the Busbar Switch in the Intelligent Substation

本文提出了一种母差位置指示装置和母差位置指示系统,用于解决传统的通过电气回路连接的刀闸位置指示装置不适用于现有的通过光信号进行信息传递的智能变电站,而通过监控后台、高压场地的智能终端面板查看线路母线侧刀闸位置的方式,存在因光纤回路异常和通讯中断等原因,造成刀闸位置不对应的风险的技术问题。

This paper presents a bus differential position indication device and bus differential position indication system,which is used to solve the problem that the traditional knife switch position indication device connected through electrical circuit is not suitable for the existing intelligent substation with information transmission through optical signal,but to view the knife switch position on the side of line bus by monitoring the intelligent terminal panel in the background and high voltage field,There is a technical problem that the knife switch position does not correspond due to abnormal optical fiber circuit and communication interruption.
