摘　　要：在对变电站内保护及自动化二次设备倒闸操作中,运行人员易出现二次设备硬压板漏投退或多投退、停送电前后压板位置不一致等错误,造成二次设备安全隐患,威胁相关变电一次设备稳定运行。本文针对变电站二次设备硬压板操作中存在安全隐患,基于二次设备硬压板倒闸操作原则,设计防误操作报警回路与压板位置监测指示灯回路,能够帮助运行操作人员有效预防二次设备硬压板误操作,效果直观,实用性强,防误可靠性强。Hidden troubles of safety exist in hard pressing plate operation of secondary devices for the substation,based on the hard pressing plate operation principle of secondary devicl,desing anti-misoperation warning circuits and monitoring indicating lamp circuits,which can help operating pessonnel effectivey to prevent the hard pressing plate misoperation of the secondary device.The result is visible and practical.
