隔离开关位置辅助判断技术比较研究

Comparative Study of the Isolating Switch Position Auxiliary Judgment Technologies

隔离开关分合位置的辅助判断技术是变电站程序化操作中的关键技术之一,其可靠性直接影响着程序化操作的成功率。本文对微动开关、传感器、视频图像识别等隔离开关位置辅助判断技术的基本原理、典型架构、安装方式进行了研究,并以此为基础对上述技术的特点进行了比较分析,提出了微动开关是一种现阶段可靠性和经济性较高的辅助判断技术,为变电站程序化操作在实践中提高隔离开关“双确认”的可靠性提供了有益的借鉴和参考。

The isolating switch position auxiliary judgment Technology is one of the key technologies in substation programmed operation,its reliability directly affects the success rate of programmed operation.In this paper,the basic principle,typical architecture and installation mode of the auxiliary judgment technologies such as micro-switch,sensor,video recognition are studied.Based on above studies,the paper compared and analyzed the characteristics of the isolating switch position auxiliary judgment technologies,and suggested that micro-switch is a judgment technology with the better reliability and economy at the present stage.The study provided a useful reference for improving the reliability of isolating switch“double confirmation”in the practice of substation programmed operation.
