369-HI-R-M-0-0-0-0繼電保護器
在鑒別時間之后和死區時間之前產生啟動或跳閘信號。
當重合閘循環被阻斷時發生跳閘（或通過阻塞I/P或通過回收時間）。
同步控制（或“死線”）和/或“CO就緒”I/P由于缺乏同步，在“t超時”期間未啟用。
“斷路器打開”信號在關閉信號后300毫秒仍處于激活狀態已復位（即CB未響應關閉信號）。
啟動信號之后的跳閘信號發生在故障持續時間“t操作”。
相位故障發生跳閘，選擇的模式：第一次重合閘周期為1P-1P或1P-3P。執行三相跳閘“跳閘3-Pol”
“跳閘3-Pol”O/P指示線路保護跳閘所有三個階段。
信號可以外部或內部連接。
如果重合閘被阻止，“CB就緒”處于非激活狀態，CB打開，單相識別時間“t1P Discrim”已過或信號“First AR”3P’是活動的。區域擴展“ZExtension”自動重合閘參數“ZE Prefault”的設置確定距離保護的故障前范圍自動重合閘功能未激活（在第一個故障之前），即，將“ZE預故障”設置為“on”將激活輸出信號“ZExtension”然后將距離函數切換為超范圍。
參數“ZE 1.AR reach”至“ZE 4.AR REATH”為每次重合閘嘗試單獨切換reach提供了便利。將其中一個參數設置為“on”意味著“ZExtension”O/P處于邏輯“1”，距離繼電器在故障發生前或在隨后的重合閘嘗試中切換為超范圍，否則距離繼電器設置為欠范圍。
除了在提供時的第一次狀態變化“ZEPrefault”設置為“ON”，它與信號“跳閘”一起復位
“斷路器”或“跳閘斷路器3P”，該信號與“關閉斷路器”信號。
距離繼電器切換到“手動”的超范圍關閉。
當自動重合閘功能時，切換至欠范圍被阻擋。
還要注意，“ZExtension”信號連接到二進制在距離中輸入區域擴展邏輯的“ZEMode AR”保護功能。
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.
