斷路器就緒信號：“CB就緒”和“CO就緒”（“CB2就緒”和“CO就緒2”）
參數(shù)“CO就緒”和“CB就緒”（或“CO”）的I/P雙工方案中的“準備就緒2”和“CB2準備就緒”）必須連接到斷路器，以便發(fā)出信號表明它們準備執(zhí)行完整的重合閘循環(huán)。如果如果未使用I/P，則必須將其設置為“真”。激活的“CB就緒”信號通知自動重合閘功能允許重合閘（即有足夠的能量用于完全打開/關閉/打開循環(huán)）。
一旦重合閘循環(huán)開始，該信號將被忽略（因為在空氣沖擊的重合閘循環(huán)期間壓力變化斷路器）。
該信號的復位在內部延遲100ms。
“CO就緒”信號（可執(zhí)行關閉-打開循環(huán)）為僅在重合閘循環(huán)期間有效，即在死區(qū)時間期間有效。
如果沒有足夠的能量打開斷路器關閉后，關閉信號再次被禁用，并出現(xiàn)“Def”。
生成跳閘（最終跳閘）。
該I/P僅與斷路器一起使用，斷路器提供相應的信息（C-O查詢），例如具有兩個開關能量的彈簧充電和空氣沖擊斷路器水平。斷路器斷開“CB斷開”（“CB2斷開”）
還必須包括斷路器的初始狀態(tài)，以防止斷路器接收到閉合信號，這是故障發(fā)生前已打開。
二進制I/P“CB open”（雙工方案中的“CB2 open”）為從而提供用于確定斷路器的初始狀態(tài)。
這些信號的拾取延遲100ms，以防止快速斷路器的意外阻塞。
“啟動”信號之前已經(jīng)打開的斷路器
自動重合閘功能未關閉接收到的（“邏輯“1”處的斷路器打開”）。
如果斷路器不提供必要的信息（“斷路器斷開”信號），則I/P必須永久設置為“關閉”（“F”或“False”）。假設方案也不是雙工的方案（即只有一個CB），二進制i/P“CB2打開”也必須永久設置為“on”（“T”或“True”）。因此，這些是“CB open”的默認設置“CB2開放”。
然后，自動重合閘功能可以在沒有“斷路器斷開”信號和無多余閉合的情況下使用單個斷路器運行為不存在的CB2生成信號。
Circuit-breaker ready signals: ‘CB ready’ and ‘CO Ready’
(‘CB2 ready’ and ‘CO Ready 2’)
The I/P’s for the parameters ‘CO Ready’ and ‘CB ready’ (or ‘CO
Ready 2’ and ‘CB2 ready’ in a duplex scheme) must be connected to the circuit-breakers in order to signal that they are
ready to perform a complete reclosure cycle. In cases where one
of the I/P’s is not used, it must be set to ‘TRUE’.
An active ‘CB ready’ signal informs the auto-reclosure function
that reclosure is permissible (i.e. sufficient energy is available for
a full open/close/open cycle).
Once a reclosure cycle has started, this signal is ignored (because the pressure varies during a reclosure cycle of an air-blast
breaker).
Resetting of this signal is internally delayed by 100 ms.
The ‘CO Ready’ signal (close-open cycle can be carried out) is
only effective during a reclosure cycle, i.e. during the dead time.
Should there be insufficient energy to open the circuit-breaker
again following closure, the close signal is disabled and a ‘Def.
Trip’ (definitive trip) is generated.
This I/P is only used in conjunction with circuit-breakers, which
provide the corresponding information (C-O query), e.g. springcharged and air-blast circuit-breakers with two switching energy
levels.Circuit-breaker open ‘CB open’ (‘CB2 open’)
It is also necessary to include the initial status of the circuitbreakers to prevent one from receiving a close signal, which was
already open before the fault occurred.
The binary I/P ‘CB open’ (and ‘CB2 open’ in a duplex scheme) is
thus provided to determine the initial status of a circuit-breaker.
The pick-up of these signals is delayed by 100 ms to prevent any
unwanted blocking of fast circuit-breakers.
A circuit-breaker which was already open before the ‘Start’ signal
was received (‘CB open’ at logical ‘1’) is not closed by the autoreclosure function.
Where a circuit-breaker does not provide the necessary information (‘CB open’ signal), the I/P must be permanently set to
‘off’ (‘F’ or ‘False’). Providing the scheme is also not a duplex
scheme (i.e. only one CB), the binary I/P ‘CB2 open’ must also
be permanently set to ‘on’ (‘T’ or ‘True’).
Accordingly, these are the default settings for ‘CB open’ and
‘CB2 open’.
The auto-reclosure function can then operate with a single circuit-breaker without a ‘CB open’ signal and no superfluous close
signal is generated for the non-existing CB2.
