IS200EACFG1B 综合继电保护器 励磁机交流反馈

产品描述



IS200EACFG1B部分是GE从EX2100系列生产的励磁机交流反馈板，用于测量励磁机电位电力变压器交流电源电压和电流。该型号配有三个9针sub-D连接器，位于励磁机辅助柜中。



IS200EACFG1B型号是IS200EAFG1型号的B版。在物理上，IS200EACFG1A和IS200EAFG1B型号之间几乎没有差异。控制器上有两个三相电压互感器。变压器块位于T3和T2，变压器在T1和T4位置被省略。



IS200EACFG1B型号是一个励磁机交流反馈板，用于控制输入电位电力变压器（PPT）电压以及空心电流变压器信号。通过EACF板的电流被发送到三个DB9连接器，这三个连接器是连接到M1、M2和C的控制器的电缆。连接励磁机反馈板所需的电缆屏蔽端子螺钉位于框架上，距离其他输入螺钉不到三英寸。



板上还有两个端子，用于两个磁通/空心线圈。IS200EACFG1B型号与励磁机背板（EBKP）一起使用，EBKP是两个板之间的控制器。该控制器上没有LED指示灯或显示器，这就是为什么IS200EACFG1B必须连接到EBKP型号，如IS200EBKPG1B型号。

Product description



The IS200EACFG1B part is GE's exciter AC feedback board from the EX2100 series, which is used to measure the exciter level AC supply voltage and current of power transformers. This model is equipped with three 9-pin sub-D connectors located in the exciter auxiliary cabinet.



IS200EACFG1B is the B version of IS200EAFG1. Physically, there is little difference between the IS200EACFG1A and IS200EAFG1B models. There are two three-phase voltage transformers on the controller. The transformer block is located at T3 and T2, and the transformer is omitted at T1 and T4.



The IS200EACFG1B model is an exciter AC feedback board for controlling input potential power transformer (PPT) voltage as well as hollow current transformer signals. The current through the EACF board is sent to the three DB9 connectors, which are cables that connect to the controllers of the M1, M2 and C. The cable shield terminal screws needed to connect the exciter feedback board are located on the frame, less than three inches from the other input screws.



There are also two terminals on the board for two flux/hollow coils. The IS200EACFG1B model is used with the exciter backplane (EBKP), which is the controller between the two boards. There is no LED indicator or display on this controller, which is why the IS200EACFG1B must be connected to an EBKP model such as the IS200EBKPG1B model.
