Honeywell SPS5710開關量模塊
圖5.9/3用于使裝置PW1002/3適應風扇電流。X軸標準化為1并表示風扇電流。負載電阻為60歐姆(等于默認值):1等于5A。Y軸在輸出中按比例縮放電壓(外部上拉電阻為2k2至5V)作為轉換器電子設備的輸出信號。2 V和3 V范圍內的值值得關注,因為這些值可以通過軟件設置為閾值,使用溫度設置參數。如果電流低于/高于交叉點-參數值/選定曲線,轉換器將生成錯誤消息。該板用于快速零電流檢測特別適用于電機中的三相磁場變換器生成器應用程序。董事會提供了一個保險箱零電流檢測,也適用于其他非常大的負載電感。
該板位于SDCS-CON-2板上,并且插入X12、X13和X17。
X17:僅用于機械原因。這個電氣功能(與IOE-1的連接)保持不變。
所有DCS/DCF轉換器均配備零通過監測電流信號進行電流檢測某一水平。CZD-01板還具有所有晶閘管的陰極/陽極電壓測量。電壓測量提供了以下方面的清晰檢測:直流負載條件。
零電流檢測的要求是:?實際負載電流低于低閾值
?上部三軸器堵塞(V11、V13、V15…)
或下部晶閘管被功率信號測量板SDCS-MP-1阻斷(V12、V14、V15…)用于服務和重建
(DCR 500/DCR 600調試)幫助。沒有這個板實際上是不可能測量的使用示波器或通用儀表控制板和電源之間的信號接口板。板插入控制板連接器X12、X13和X17。帶狀電纜正常
連接到控制板,連接到測量板連接器具有:與上相應連接器的名稱相同控制板。
提供以下信號的測量點
-三相接地電壓UU、UV和華盛頓大學
-三相電壓UVU、UWV和UUW
-一個整流和濾波的相間電壓UAC
帶符號濾波的電樞電壓UDC
-帶符號的電樞電流IACT
-六個晶閘管點火命令BZP1…BZP6
-兩個電流方向命令SR1和SR2
SR2(測量點SR11和SR21)
-脈沖變壓器一次電流之和
可通過測量點進行測量SR11-SR12或SR21-SR22,取決于電流方向
-控制板接地0V。
測量點與控制板信號,帶10 k電阻或帶運算放大器,使意外短路測量點之間的電路不影響轉換器的工作。測量點0V直接連接到控制板接地。
The power signal measurement board SDCS-MP-1
is intended to be used as a service and rebuild
(DCR 500 /DCR 600 commissioning) aid. Without
this board it is practically impossible to measure
with oscilloscope or with general purpose meter
signals between the control board and the power
interface board(s).
The board is plugged to the control board connectors X12, X13 and X17. The ribbon cables normally
connected to the control board are connected to
the measurement board connectors having the
same name as the respective connector on the
control board.
Measurement points for following signals are provided:
- the three phase to ground voltages UU, UV and
UW
- the three phase to phase voltages UVU, UWV and
UUW
- one rectified and filtered phase to phase voltage
UAC
- armature voltage UDC with sign filtered
- armature current IACT with sign
- the six thyristor firing commands BZP1...BZP6
- the two current direction commands SR1 and
SR2 (measurement points SR11 and SR21)
- the sum of pulse transformer primary currents
can be measured accross measurement points
SR11-SR12 or SR21-SR22 depending on current
direction
- the control board ground 0V.
The measurement points are separated from the
control board signals either with 10 k resistors or
with operational amplifiers so that accidental short
circuits between the measurement points do not affect the converter operation. Measurement point 0V
is directly connected to control board ground.
