WES5302-150自动化卡件
当发出关闭命令时，该信号开始出现，并且如果在重合闸时发生跳闸，则在时间“t Close”结束或更早时复位。自动重合闸功能的状态（“AR就绪”和“AR阻塞的‘）
自动重合闸时产生信号“AR就绪”功能已准备好执行重合闸循环，信号“AR当它被阻止时“被阻止”。
“AR就绪”信号激活，前提是重合闸周期未阻塞（无“AR阻塞”信号）且死区时间未运行。
“AR就绪”信号在重新闭合命令期间激活启用同步检查功能的目的（参见中的图3同步检查功能部分）。正在进行自动重合闸循环
有六个信号表明重合闸循环正在运行，并且达到了什么阶段：“程序中的AR”正在进行重合闸循环
“首次AR 1P”首次单相重合闸尝试
“首次AR 3P”首次三相重合闸尝试“第二次AR”第二次重合闸尝试
“第三次AR”和第三次重合闸尝试
“第四次AR”是第四次重合闸尝试。
信号“AR in prog”在死区时间开始时拾取由最后一个重合闸命令的下降沿复位。
断路器闭合信号“闭合CB”和“闭合CB2”
CB闭合命令通常分配给重型
通过相应配置参数，辅助O/P继电器
“关闭CB”（在双工方案中也称为“关闭CB2”）。也可以将相同的信号分配给以下信令O/P：参数名称相同。
在“关闭”期间，关闭命令之后的跳闸+300ms切换死区时间步长（第二、第三和第四AR）或启动锁定跳闸（取决于设置）。接近跳闸后立即重置命令。
确定的行程。旅行“Def。“跳闸”信号表示断路器将保持
跳闸，不再尝试再次重合闸。以下情况可能导致最终跳闸：所有重合闸尝试均未成功
This signal picks up when the closing command is issued and
resets at the end of the time ‘t Close’ or earlier if there is a tripping occurs upon reclosing.
Status of the auto-reclosure function (‘AR Ready’ and ‘AR
Blocked’)
The signal ‘AR Ready’ is generated when the auto-reclosure
function is ready to perform a reclosure cycle and the signal ‘AR
Blocked’ when it is blocked.
The ‘AR Ready’ signal is active providing a reclosure cycle is not
blocked (no ‘AR Blocked’ signal) and a dead time is not running.
The ‘AR Ready’ signal is active during a reclose command for
purposes of enabling the synchrocheck function (see Fig. 3 in
the synchrocheck function section).Auto-reclosure cycle in progress
There are six signals which show that a reclosure cycle is running and what stage has been reached:
'AR in prog.' reclosure cycle in progress
'First AR 1P' first single-phase reclosure attempt
'First AR 3P' first three-phase reclosure attempt
‘second AR' second reclosure attempt
'Third AR' third reclosure attempt
'Fourth AR' fourth reclosure attempt.
The signal ‘AR in prog’ picks up at the start of the dead time and
is reset by the falling edge of the last reclose command.
Circuit-breaker closing signals ‘Close CB’ and ‘Close CB2'
The CB closing command is normally assigned to a heavy-duty
auxiliary O/P relay by correspondingly configuring the parameter
‘Close CB’ (also ‘Close CB2’ in a duplex scheme). It is also possible to assign the same signal to a signalling O/P under the
same parameter name.
A trip subsequent to a close command during the time ‘t Close’ +
300 ms switches the dead time step (second, third and fourth
AR) or initiates a lock-out trip (depending on the setting). A close
command is reset immediately after a trip.
Definitive trip ‘Def. Trip'
The ‘Def. Trip’ signal indicates that the circuit-breaker will remain
tripped and no further reclosure attempts will be made. The following conditions can cause a definitive trip:
All reclosure attempts were unsuccessful
