ABB 086318-501扩展驱动模块

外部电压调节变阻器（端子R1和R2）：端子R1和R2用于连接电压调节变阻器。
这个变阻器提供调节发电机电压的±10%名义上的它作为面板安装的单独项目提供。连接变阻器的导线连接到端子R1和R2。跨接导线必须连接在变阻器端子2和变阻器1之间如图6所示。
连接至无功电压降端子CT _、CT1和CT5并联运行：当发电机并联运行时，安装
B相电流互感器从每个发电机引出，并连接为跟随-电流互感器（1 A次级）：将次级引线连接到CT-公共和CT1。确保保持正确的极性。制作确保跨接器在提供时已从CT上拆除CT1。
-电流互感器（5 A次级）：将次级引线连接到CT公共和CT5。确保保持正确的极性。制作
确保跨接器在提供时已从CT上拆除CT1。
无功电压降或交叉电流补偿：调节系统可在无功状态下并联运行
电压下降或交叉电流补偿模式。按无功电压下降或交叉电流补偿。
-无功电压降：将电流互感器连接到各自的调节器（见图7）。
-交叉电流补偿：对于交叉电流，连接每个CT至其各自的调节器。然后连接 尼什 rst CT to第三个CT的开始等继续，直到所有CT连接到串联并连接 从后一个CT结束到 rst CT
-并联交叉电流补偿应用包括：对于两台或多台发电机，如果所有发电机并不总是在公共汽车上。如果不使用开关，系统将引入电压降，这将使输入发电机的电压： 在之前完成平行。这是由于发电机并联CT空载，而不是提供其补偿信号，但允许电压降发生在其上。理想情况下，开关是发电机上的辅助开关断路器闭合时断开的输出断路器。）对于单相传感，端子为E1和E3。见图2和图3。
2）那个 发电机运行时，eld不得打开、短路或接地。
3）外部电压调节器端子1和2之间必须有跨接导线。
4）输入功率标准KCR 760电压为120 Vac；可选240伏交流电。大限度
120伏交流输入的连续输出为65伏直流电，240伏交流输入为125伏直流电。看见图4和图5。
5）并联运行的发电机需要电流互感器。连接如图所示：1 A电流互感器和无功电压降
补偿参见图2和图3。
6）根据适用的电气规范将中性点接地External voltage adjust rheostat (terminals R1 and R2): Terminals
R1 and R2 are provided for connection of the voltage adjust rheostat. The
rheostat provides adjustment of the regulated generator voltage ±10% of
nominal. It is provided as a separate item for panel mounting. Connecting
wires from the rheostat attach to terminals R1 and R2. A jumper wire
must be connected between rheostat terminal 2 and rheostat terminal 1 as
shown in Figure 6.
Connection to reactive voltage droop terminals CT, CT1, and CT5
Parallel operation: When generators will be operating in parallel, install
the current transformer in Phase B from each generator and connect as
follows:
- Current transformer (1 A secondary): Connect secondary leads to
CT common and CT1. Be sure to maintain correct polarity. Make
certain the jumper, when supplied, is removed from across CT and
CT1.
- Current Transformer (5 A secondary): Connect secondary leads to
CT common and CT5. Be sure to maintain correct polarity. Make
certain the jumper, when supplied, is removed from across CT and
CT1.
Reactive voltage droop or cross-current compensation: The regulating
system may be connected for parallel operation in either the reactive
voltage droop or cross-current compensation mode. Connect according to
either reactive voltage droop or cross-current compensation.
- Reactive voltage droop: Connect the current transformer to the
respective regulator (see Figure 7).
- Cross-current compensation: For cross-current, connect each CT
to its respective regulator. Then connect the  nish of the  rst CT to
the start of the third CT, etc. Continue until all CTs are connected in
series and connect the  nish of the last CT to the start of the  rst CT
(see Figure 8).
- On parallel cross-current compensation applications consisting
of two or more generators, use a unit/parallel switch if all the
generators are not always on the bus. If the switch is not used,
a voltage droop will be introduced into the system, which will
cause the voltage of the incoming generator to  uctuate prior to
paralleling. This is due to the unloaded generator parallel CT not
supplying its compensating signal, but allowing a voltage drop to
occur across it. Ideally, the switch is an auxiliary on the generator
output circuit breaker that opens when the breaker is closed.) For single-phase sensing, terminals are E1 and E3. See Figures 2 and 3.
2) The  eld must not be opened, shorted or grounded while the generator is operating.
3) The external voltage adjust must have a jumper across its terminals 1 and 2.
4) Input power standard KCR 760 voltage is 120 Vac; optional 240 Vac. Maximum
continuous output is 65 Vdc for a 120 Vac input and 125 Vdc for a 240 Vac input. See
Figures 4 and 5.
5) A current transformer is required for generators operating in parallel. The connection is shown on this drawing: 1 A current transformer and reactive voltage droop
compensation. See Figures 2 and 3.
6) Ground the neutral in accordance with applicable electrical codes
