WES13-3继电卡件
2或1½也需要识别时间“t Discrim 3P”断路器方案，其中每个断路器都有自己的自动重合闸功能。
参数“t Discrim 1P”或“t discrem”的典型设置单相和三相重合闸的3P'为最短值的50%这是一个死时间。
识别时间的最小允许设置为：100ms+CB时间
注：时间“t1EvolFaults”，在此期间，后续故障必须检测到（演变或不成功重合闸）是距离功能设置。
距离保护参数“t1EvolFaults”启用后续故障（演变或不成功重合闸）导致三相跳闸的时间，即距离保护功能的第二次跳闸使所有三个跳闸阶段。自动重合闸功能还发出切换信号
通过在故障识别时间的结束时间t Discrim。1P′。建议将时间“t1EvolFaults”设置为比自动重合闸死区时间“t Dead1 1P”长。“t超时”
参数't Timeout'确定死后的时间段必须发出关闭信号的时间，否则”“是的。“跳闸”被生成，并且没有进行进一步的重合闸尝试。
在每个死区时间结束时发出关闭命令之前
逻辑[（'synchroChck'和'CO ready'）或'Dead Line'或“ExtSCBypas”）]被选中，并且只有在“t超时”设置范围内所有条件都正确的情况下才启用该命令。如果在重合闸循环期间出现“CondBlkAR”信号（即。
“程序中的AR”信号激活），它只有在当前重合闸循环的结束，前提是它仍然有效。在机组运行期间，重合闸循环保持闭锁状态启用最后一个二进制I/P后的阻塞时间“t AR Block”。当辅助电源接通或参数设置加载时，保护继电器初始化期间也会发生闭锁。为了控制自动重合闸功能，必须配置三个I/P信号“跳闸CB”（一般跳闸），“跳闸CB 3P”（三相跳闸）和“启动”。实现这一点的正常程序
通过子菜单“输出”选择保护信号来自函数'。由于自动重合闸功能完全独立，来自其他功能的信号也可能挑选出来的。
The discrimination time ‘t Discrim 3P’ is also needed for 2 or 1½
breaker schemes, where each circuit-breaker has its own autoreclosure function.
A typical setting for the parameters ‘t Discrim 1P’ or ‘t Discrim
3P’ for single and three-phase reclosure is 50 % of the shortest
dead time.
The minimum permissible setting for the discrimination time is:
100 ms + CB time
Note:
The time ‘t1EvolFaults’ during which a subsequent fault has to
be detected (evolving or unsuccessful reclosure) is a distance
function setting.
The distance protection parameter ‘t1EvolFaults’ enables the
time to be set during which a subsequent fault (evolving or unsuccessful reclosure) results in a three-phase trip, i.e. every
second trip by the distance protection function trips all three
phases. The auto-reclosure function also signals the switchover
to three-phase tripping by exciting the signal ‘Trip 3-Pol’ at the
end of the fault discrimination time ‘t Discrim. 1P’.
It is advisable to set the time ‘t1EvolFaults’ longer than the autoreclosure dead time ‘t Dead1 1P’.
't Timeout'
The parameter ‘t Timeout’ determines the period after the dead
time within which the close signal must be issued, otherwise a
‘Def.Trip’ is generated and no further reclosure attempt is made.
Before a close command is issued at the end of every dead time,
the logic [(‘synchroChck’ AND ‘CO ready’) OR ‘Dead Line’ OR
‘ExtSCBypas’)] is checked and the command only enabled providing all the criteria are correct within the setting of ‘t Timeout’.Should a ‘CondBlkAR’ signal occur during a reclosure cycle (i.e.
the ‘AR in prog.’ signal is active), it only becomes effective from
the end of the current reclosure cycle and providing it is still active.
A reclosure cycle remains blocked for the duration of the set
blocking time ‘t AR Block’ after the last binary I/P has been enabled. Blocking also takes place during initialisation of the protection relay when its auxiliary supply is switched on or the parameter settings are being loaded.In order to control the auto-reclosure function, it is necessary to
configure the three I/P signals ‘Trip CB’ (general trip), ‘Trip CB 3P’
(three-phase trip) and ‘Start’. The normal procedure to achieve this
is to select the protection signals via the sub-menu ‘OUTPUT
FROM FUNCTION’. Since the auto-reclosure function is completely independent, signals from other functions may also be
selected.
