DS200PTCTG1ABC  GE  Mark V 单工控制系统 用作电位变压器电流互感器（PTCT）板

产品描述

DS200PTCTG1ABC用作电位变压器电流互感器（PTCT）板。它用于隔离和调整来自 CT 和 PT 的电压和电流信号。该板还为 Mark V 系统提供用于低压电流信号的辅助输入。在DS200PTCTG1ABC上隔离信号后，它们被发送到TCCB传感器板。JKK 带状连接器从该板安装到 TCCB 板，并通过隔离变压器的次级。此外，DS200PTCTG1ABC接受三组三相PT输入中的一组进入系统。这些PT输入被控制系统用作可选的电压匹配功能。

DS200PTCTG1ABC板具有四个独立的端子条，沿一个长板边缘排列。DS200PTCTG1ABC这些端子上的大多数端子连接器都沿电路板表面单独标记，但不是全部。在电路板的另一侧，有一个用于 JKK 带状连接器的垂直连接器。其他电路板元件位于这些元件之间，包括202个框架变压器和<>个环形变压器，以及多个跳线开关、AD<>JY隔离放大器、电阻网络阵列、电阻和电容。该板标有通用电气徽标、板识别号以及几个有助于安装的代码。这对于像这样的电路板尤其重要，即使在主电源断开后，电压也可能存在。

DS200PTCTG1ABC is used as a potential transformer current transformer (PTCT) board. It is used to isolate and adjust voltage and current signals from CT and PT. This board also provides auxiliary inputs for low-voltage current signals for the Mark V system. After isolating signals on DS200PTCTG1ABC, they are sent to the TCCB sensor board. The JKK ribbon connector is installed from this board to the TCCB board and passes through the secondary of the isolation transformer. In addition, DS200PTCTG1ABC accepts one of the three sets of three-phase PT inputs into the system. These PT inputs are used by the control system as optional voltage matching functions.

The DS200PTCTG1ABC board has four independent terminal strips arranged along the edge of a long board. Most of the terminal connectors on DS200PTCTG1ABC terminals are individually marked along the surface of the circuit board, but not all of them. On the other side of the circuit board, there is a vertical connector for the JKK ribbon connector. Other circuit board components are located between these components, including 202 frame transformers and<>ring transformers, as well as multiple jumper switches, AD<>JY isolation amplifiers, resistor network arrays, resistors, and capacitors. The board is marked with the General Electric logo, board identification number, and several codes to aid in installation. This is particularly important for circuit boards like this, as voltage may still exist even after the main power supply is disconnected.
