产品详情资料

控制单元包括以下主要模块：
-微控制器80C198用于控制和点火
-交流时的实际直流电流测量
电流互感器。
-转换器控制器的RS485接口
SDCS-CON-x板。
磁场电流控制软件存储在
80C198的ROM存储器
这通过使用电流控制器的PI结构来完成。控制或所需的所有参数
缩放原因（选择负载电阻器）如下：
存储在电枢的非易失性存储器中
并在每个初始化过程中通过RS485链路传输到现场控制器。
节点编号始终固定编码为节点
数量＝1。
输出Iact表示实际场电流，
通过交流变压器测量，然后
整流并转换为电压信号
负载电阻。如前所述，负载电阻器由电路板自身根据标称磁场电流的设置进行调整
电机（见前面的列表）。由此产生的负担

8.2.3动力部分
两个二极管晶闸管模块布置为
半控制单相整流器。阳极
这两个二极管不直接连接
其他照常；它们现在连接到两端
电流互感器的四匝初级绕组。中心抽头是的负输出
整流器。因此，可以用交流电流互感器测量直流电流。
MOV（金属氧化物变阻器）保护交流输入
防止来自外部电源的电压尖峰。
另一个MOV保护直流输出免受直流电机励磁绕组引起的电压浪涌。The control unit includes the following main blocks:
- Micro controller 80C198 for controlling and firing
- Actual DC current measurement with an AC
current transformer.
- RS485 interface to the converter's controller
board SDCS-CON-x.
The software for the field current control is stored in
the ROM memory of the 80C198. The control is
done by using a PI structure for the current controller. All parameters needed for the control or for
scaling reasons (selection of burden resistors) are
stored in the non-volatile memory of the armature
converter and transferred to the field controller during each initializing process via the RS485 link.
The Node number is always fix coded to Node
number = 1.
The output Iact represents the actual field current,
which is measured via the AC transformer, then
rectified and transferred into a voltage signal with
burden resistors. The burden resistors, as mentioned before, are adapted by the board itself depending on the setting of the nominal field current
of the motor (see list before). The resulting burden
voltage can be measured at test terminals beside
X14:. The 2.2 K
resistor allows a short circuit at
the terminals; the external measuring device should
have an internal resistance higher than 1M
.
The terminal row X20: is used for test purposes.
8.2.3 Power section
Two diode-thyristor modules are arranged as a
half-controlled single-phase rectifier. The anodes of
the two diodes are not connected directly to each
other as usual; they are now connected to the ends
of the four turn primary winding of the current transformer. The centre tap is the negative output of the
rectifier. Thus it is possible to measure the DC current with an AC current transformer.
A MOV (Metal Oxide Varistor) protects the AC input
against voltage spikes from the external source.
Another MOV protects the DC output against voltage surges which can be caused by the field winding of a DC machine.
