基于姿态传感的隔离开关位置监测系统设计与实现

Design and Implementation of Disconnect Switch Position Monitoring System Based on Attitude Sensor

文中设计了一套基于姿态传感的隔离开关分合闸位置监测系统,实现隔离开关分合闸状态的精确判别,与传统辅助开关接点实现隔离开关分合闸位置的方式形成非同源的位置"双确认"判据,为一键顺控操作提供辅助判别支撑,满足变电站信息安全可靠性要求。试验证明,文中设计的系统具有较好的稳定性、准确性和可靠性,为一键顺控技术的工程实施起到了一定的推动作用。

In this paper,a position monitoring system based on attitude sensing was designed to accurately identify the opening and closing status of the disconnector.A non-homologous position"double confirmation"criterion was formed by realizing the opening and closing position of the disconnector with the traditional auxiliary switch contacts,which provided auxiliary discrimination support for one-key sequential operation and met the requirement of substation information security and reliability.The experiment results show that the system designed in this paper has good stability,accuracy and reliability,and it plays a certain role in promoting the implementation of one-key sequence control technology.
