3BSE056767R1控制模块
同步检查和关闭/打开准备信号的旁路第一次单相或三相重合闸:
“on”第一次重合闸未通过同步检查启用,并且关闭/打开就绪信号(旁路始终处于激活状态)。
通过同步检查和关闭/打开就绪信号(旁路未激活)。Ext.SCBypas绕过“同步时钟”和“CO就绪”信号。
如果不需要,则设置为“off”(“F”或“False”)。启用关闭命令的I/P逻辑:[(“同步检查”和“CO-Ready”)或“死线”或“Ext.SCBypas”]。用于启用关闭命令的I/P逻辑:[('synchroChk2'和“CO就绪2”)或“死线”或“Ext.SCBypas”]。
同步器来自同步检查继电器的信号的I/P。
设置为“开”(“T”或“真”),如果不需要,则不安装和“死”未使用“行”或“ExtSCBypas”。
I/P逻辑:[(“同步检查”和“CO就绪”)或“死线”或“Ext.SCBypas”]。
区域扩展
为了实现下述功能,必须将“ZExtension”信号连接到距离保护功能(参见第3.5.32.2节)。
该信号可用于启动包括过电流功能的方案中的快速跳闸(见第3.5.32.3节)。ZE Prefault
第一次故障前的距离继电器到达设置:“on”超范围(“ZExtension”信号激活)
“关闭”欠伸(“ZExtension”信号无效)。ZE 1.AR距离继电器到达后的第一。重合闸尝试:
“on”超范围(“ZExtension”信号激活)“关闭”欠伸(“ZExtension”信号无效)。
ZE 2.AR距离继电器在第二次之后的到达。重合闸尝试:
“on”超范围(“ZExtension”信号激活)“关闭”欠伸(“ZExtension”信号无效)。
ZE 3.AR第三次重合闸尝试后距离继电器的到达范围:“on”超范围(“ZExtension”信号激活)“关闭”欠伸(“ZExtension”信号无效)
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)
