3BSE056767R1控制模塊
同步檢查和關(guān)閉/打開準(zhǔn)備信號的旁路第一次單相或三相重合閘:
“on”第一次重合閘未通過同步檢查啟用,并且關(guān)閉/打開就緒信號(旁路始終處于激活狀態(tài))。
通過同步檢查和關(guān)閉/打開就緒信號(旁路未激活)。Ext.SCBypas繞過“同步時鐘”和“CO就緒”信號。
如果不需要,則設(shè)置為“off”(“F”或“False”)。啟用關(guān)閉命令的I/P邏輯:[(“同步檢查”和“CO-Ready”)或“死線”或“Ext.SCBypas”]。用于啟用關(guān)閉命令的I/P邏輯:[('synchroChk2'和“CO就緒2”)或“死線”或“Ext.SCBypas”]。
同步器來自同步檢查繼電器的信號的I/P。
設(shè)置為“開”(“T”或“真”),如果不需要,則不安裝和“死”未使用“行”或“ExtSCBypas”。
I/P邏輯:[(“同步檢查”和“CO就緒”)或“死線”或“Ext.SCBypas”]。
區(qū)域擴(kuò)展
為了實現(xiàn)下述功能,必須將“ZExtension”信號連接到距離保護(hù)功能(參見第3.5.32.2節(jié))。
該信號可用于啟動包括過電流功能的方案中的快速跳閘(見第3.5.32.3節(jié))。ZE Prefault
第一次故障前的距離繼電器到達(dá)設(shè)置:“on”超范圍(“ZExtension”信號激活)
“關(guān)閉”欠伸(“ZExtension”信號無效)。ZE 1.AR距離繼電器到達(dá)后的第一。重合閘嘗試:
“on”超范圍(“ZExtension”信號激活)“關(guān)閉”欠伸(“ZExtension”信號無效)。
ZE 2.AR距離繼電器在第二次之后的到達(dá)。重合閘嘗試:
“on”超范圍(“ZExtension”信號激活)“關(guān)閉”欠伸(“ZExtension”信號無效)。
ZE 3.AR第三次重合閘嘗試后距離繼電器的到達(dá)范圍:“on”超范圍(“ZExtension”信號激活)“關(guān)閉”欠伸(“ZExtension”信號無效)
Bypass of the synchrocheck and close/open ready signals for
the first single or three-phase reclosure:
'on' First reclosure not enabled by synchrocheck and
close/open ready signals
(bypass always active).
'off' First reclosure enabled by synchrocheck and
close/open ready signals
(bypass inactive).Ext.SCBypas
Bypasses the ‘synchroChck’ and ‘CO Ready’ signals.
Set to ‘off’ (‘F’ or ‘False’), if not needed.
I/P logic for enabling the close command: [(‘synchrocheck’
AND ‘CO Ready’) OR ‘Dead line’ OR ‘Ext.SCBypas’].
I/P logic for enabling the close command: [(‘synchroChk2’
AND ‘CO Ready 2’) OR ‘Dead line’ OR ‘Ext.SCBypas’].
SynchroChck
I/P for a signal from a synchrocheck relay.
Set to ‘on’ (‘T’ or ‘True’), if not needed, not fitted and ‘Dead
line’ or ‘ExtSCBypas’ not used.
I/P logic: [(‘synchrocheck’ AND ‘CO Ready’) OR ‘Dead line’
OR ‘Ext.SCBypas'].
ZONE EXTENSION
To achieve the functions described below, the ‘ZExtension’ signal must be connected to the distance protection function (see
Section 3.5.32.2.).
This signal can be used to initiate fast tripping in schemes including overcurrent functions (see Section 3.5.32.3.).
ZE Prefault
Distance relay reach setting before the first fault:
'on' overreaching (‘ZExtension’ signal active)
'off' underreaching (‘ZExtension’ signal inactive).
ZE 1. AR
Distance relay reach after the 1st. reclosure attempt:
'on' overreaching (‘ZExtension’ signal active)
'off' underreaching (‘ZExtension’ signal inactive).
ZE 2. AR
Distance relay’s reach after the 2nd. reclosure attempt:
'on' overreaching (‘ZExtension’ signal active)
'off' underreaching (‘ZExtension’ signal inactive).
ZE 3. AR
Distance relay’s reach after the 3rd.. reclosure attempt:
'on' overreaching (‘ZExtension’ signal active)
'off' underreaching (‘ZExtension’ signal inactive)
