单相接地跳闸和重合闸故障（单相死区时间），相位故障无重合闸
1.1P-3P单相跳闸后接三相约20 ms后跳闸，接地故障的三相重合闸（三相由单相跳闸启动的死区时间），
三相故障无重合闸1.接地1P3P-3P三相跳闸和重合闸和相位故障（三相死区时间）
1.1P3P-1P3P单相接地跳闸和重合闸故障（单相死区时间）、三相跳闸和相故障重合闸（三相死区时间）
外部选择：通过二进制输入进行外部选择1P_ 1P、MD1_，
MD1_EXT_1P3P_3P和自最后一次重合闸尝试下降沿起的MD1_EX_1P3P_1P3周期（CB恢复时间），在此期间，自动重合闸功能为被阻止，之后该功能被重置。
如果歧视和死区时间，一段时间从另一段时间的瞬间开始两次之间发生的跳闸。
如果保护在以下情况下跳闸，回收计时器也会启动：故障持续时间“t Oper”已过。条件阻塞信号的I/P。
阻塞仅在AR循环未进行时发生。
如果不需要，则设置为“off”（“F”或“False”）。当跳闸由距离保护SOTF逻辑或方向E/F PLC信号，相应的信号可以连接到该I/P以防止自动重合闸。手动关闭阻止由手动断路器关闭信号激励的I/P。
即使是正在进行的自动重合闸循环也会立即被施加到该输入的信号阻止。
如果不需要，则设置为“off”（“F”或“False”）。抑制Inp。
I/P，用于在冗余状态下阻止跟随器重合闸功能
计划从主对象的末端阻止跟随器关闭信号，直到回收时间结束。
如果不需要，则设置为“off”（“F”或“False”）。扩展t1
有条件延长死区时间的输入（单和三相）用于第一次（快速）重合闸。
如果不需要，则设置为“off”（“F”或“False”）。
single-phase trip and reclosure for earth
faults (single-phase dead time), no reclosure for phase faults
1. 1P-3P single-phase trip followed by three phase
trip after approx. 20 ms, three-phase reclosure for earth faults (three-phase
dead time initiated by single-phase trip),
no reclosure for -phase faults
1. 1P3P-3P three-phase trip and reclosure for earth
and phase faults (three-phase dead time)
1. 1P3P-1P3P single-phase trip and reclosure for earth
faults (single-phase dead time), threephase trip and reclosure for phase faults
(three-phase dead time)
Ext.Selection External selection by the binary inputs
MD1_EXT_1P_1P, MD1_EXT_1P_3P,
MD1_EXT_1P3P_3P and
MD1_EX_1P3P_1P3PPeriod (CB recovery time) from the falling edge of the last reclosure attempt during which the autoreclosure function is
blocked and after which the function is reset.
In the event of an evolving fault between discrimination and
dead times, the period commences at the instant of another
trip occurring between the two times.
The reclaim timer is also started if the protection trips after
the fault duration time ‘t Oper’ has elapsed.I/P for a conditional blocking signal.
Blocking only takes place providing an AR cycle is not in progress.
Set to ‘off’ (‘F’ or ‘False’), if not needed.
When tripping is by the distance protection SOTF logic or a
directional E/F PLC signal, the corresponding signals can be
connected to this I/P to prevent auto-reclosure.
Manual Close
Blocking I/P excited by the manual CB close signal.
Even an autoreclosure cycle that is in progress is immediately blocked by a signal applied to this input.
Set to ‘off’ (‘F’ or ‘False’), if not needed.
Inhibit Inp.
I/P for blocking the follower reclosure function in a redundant
scheme. The follower is blocked from the end of the master
closing signal until the end of the reclaim time.
Set to ‘off’ (‘F’ or ‘False’), if not needed.
Extend t1
Input for conditionally extending the dead time (single and
three-phase) for the first (fast) reclosure.
Set to ‘off’ (‘F’ or ‘False’), if not needed.
