摘　　要：通过对某110kV变电站旁代操作中涉及的110kV备自投装置“旁代压板”投退顺序的典型错误进行分析,阐述旁代操作中旁代压板的错误投退对备自投跳闸逻辑、和电流逻辑及放电逻辑的影响,提炼归纳出一种安自装置旁代压板操作顺序,以保证在旁代操作过程中备自投逻辑的准确可靠动作。By analyzing the typical errors in the bypass platen switching sequence of 110 kV backup automatic switching device in the bypass operation of a certain 110 kV substation,the impact of incorrect switching of bypass platens in the bypass operations on the backup automatic switching trip logic,current logic,and discharge logic are expounded,based on which a kind of bypass platen operation sequence for safety automation device is proposed so as to ensure accurate and reliable actions of backup automatic switching logic in bypass operations.
