摘要
分析了110kV微机保护装置电源正常情况下,当控制电源消失后又恢复时,重合闸发生误动的原因,即当重合闸在选择非同期或检无压方式时会发生误动,只有当选择检同期方式且线路无压时才不发生误动。因此在实际工作中应采取预防重合闸误动的措施。
The cause of reclosing maloperation was analyzed when the power source of 110 kV microcomputer protection device was in the normal condition and the control power source was disappeared and then resumed again. This means that the maloperation can occur in asynchronous or non - voltage mode of automatic reclosing, and only in selecting the synchronous mode and non - voltage on transmission line, the maloperation cannot occur.
