摘　　要：智能变电站的建设需要对站内二次设备进行重点升级或换代,其中保护硬压板作为变电站关键二次设备之一,其投入与退出时动作是否到位对于变电站安全运行具有重要意义。针对传统保护硬压板操作人力消耗大、机械断点易开合不到位的问题以及满足现今无人值守工作模式的发展需要,设计了一种采用非同一原理工作状态检测技术的新型保护硬压板,检测过程采用工作电压与动作执行双重检测,并使用“与”运算方式,其中电压检测环节基于采样频率自适应更新与抽取突变算法,保证压板工作状态检测结果的正确性。工程应用表明所提自动保护压板及其检测方法具有有效性。The construction of smart substations requires key upgrades or replacements of secondary equipment in the substation.Among them,the protective hard plate is one of the key secondary equipment of the substation.Whether its input and withdrawal actions are in place is of great significan ce to the safe operation of the substation.In order to solve the problems of traditional protective hard plate operation,which consumes a lot of manpower,mechanical breakpoints are easy to open and close,and to meet the development needs of today’s unattended working mode,a new protective hard plate using non-identical principle working status detection technology was designed.The detection process uses working voltage and action to perform dual detection,and uses the‘AND’operation method.The voltage detection link is based on the sampling frequency adaptive update and extraction mutation calculation method to ensure the accuracy of the detection results of the pressure plate working status.Engineering applications demonstrate the effectiveness of the proposed automatic protection pressure plate and its detection method.
