369-HI-R-M-0-0-0-0继电保护器
在鉴别时间之后和死区时间之前产生启动或跳闸信号。
当重合闸循环被阻断时发生跳闸（或通过阻塞I/P或通过回收时间）。
同步控制（或“死线”）和/或“CO就绪”I/P由于缺乏同步，在“t超时”期间未启用。
“断路器打开”信号在关闭信号后300毫秒仍处于激活状态已复位（即CB未响应关闭信号）。
启动信号之后的跳闸信号发生在故障持续时间“t操作”。
相位故障发生跳闸，选择的模式：第一次重合闸周期为1P-1P或1P-3P。执行三相跳闸“跳闸3-Pol”
“跳闸3-Pol”O/P指示线路保护跳闸所有三个阶段。
信号可以外部或内部连接。
如果重合闸被阻止，“CB就绪”处于非激活状态，CB打开，单相识别时间“t1P Discrim”已过或信号“First AR”3P’是活动的。区域扩展“ZExtension”自动重合闸参数“ZE Prefault”的设置确定距离保护的故障前范围自动重合闸功能未激活（在第一个故障之前），即，将“ZE预故障”设置为“on”将激活输出信号“ZExtension”然后将距离函数切换为超范围。
参数“ZE 1.AR reach”至“ZE 4.AR REATH”为每次重合闸尝试单独切换reach提供了便利。将其中一个参数设置为“on”意味着“ZExtension”O/P处于逻辑“1”，距离继电器在故障发生前或在随后的重合闸尝试中切换为超范围，否则距离继电器设置为欠范围。
除了在提供时的第一次状态变化“ZEPrefault”设置为“ON”，它与信号“跳闸”一起复位
“断路器”或“跳闸断路器3P”，该信号与“关闭断路器”信号。
距离继电器切换到“手动”的超范围关闭。
当自动重合闸功能时，切换至欠范围被阻挡。
还要注意，“ZExtension”信号连接到二进制在距离中输入区域扩展逻辑的“ZEMode AR”保护功能。
A starting or tripping signal was generated after the discrimination time and before dead time.
Tripping takes place while a reclosure cycle is blocked (either
via the blocking I/P or by the reclaim time).
The ‘synchroChck’ (or ‘Dead line’) and/or ‘CO Ready’ I/P’s
were not enabled during ‘t Timeout’ due to lack of synchronism.
The ‘CB open’ signal is still active 300 ms after the close signal
has reset (i.e. the CB has not responded to the close signal).
The trip signal that followed the start signal occurred after the
fault duration time ‘t Oper’.
Tripping occurred for a phase fault and the mode selected for
the first reclosure cycle is 1P-1P or 1P-3P.Perform three-phase trip ‘Trip 3-Pol'
The ‘Trip 3-Pol’ O/P instructs the line protection to trip all three
phases.
The signal can be externally or internally connected.
This signal is generated automatically, if reclosure is blocked,
‘CB Ready’ is inactive, the CB is open, the single-phase discrimination time ‘t1P Discrim’ has elapsed or the signal ‘First AR
3P’ is active.
Zone extension ‘ZExtension’
The setting of the auto-reclosure parameter ‘ZE Prefault’ determines the pre-fault reach of the distance protection when the
auto-reclosure function is inactive (before the first fault), i.e. setting ‘ZE Prefault’ to ‘on’ activates the output signal ‘ZExtension’
which then switches the distance function to overreach.
The parameters ‘ZE 1. AR reach’ to ‘ZE 4. AR reach’ provide facility for individually switching the reach for each reclosure attempt. Setting one of these parameters to ‘on’ means that the
‘ZExtension’ O/P is at logical ‘1’ and the distance relay is switched to overreach either before fault occurrence or for the followingreclosure attempt, otherwise the distance relay is set to underreach.
With the exception of its first change of state when providing
‘ZEPrefault’ is set to ‘ON’ it resets together with the signal ‘Trip
CB’ or ‘Trip CB 3P’, this signal picks up and resets together with
the ‘Close CB’ signal.
The distance relay is switched to overreaching for a ‘Manual
close’.
It is switched to underreaching when the auto-reclosure function
is blocked.
Note also that the ‘ZExtension’ signal is connected to the binary
input ‘ZEMode AR’ of the zone extension logic in the distance
protection function.
