IS200EPSMG1A与IS200EPSMG1ADC数字量32点励磁电源模块介绍

一、概述

IS200EPSMG1A和IS200EPSMG1ADC是由GE公司根据Mark VI涡轮机控制系统开发的数字量32点励磁电源模块。这两款模块在励磁控制系统和调节器控制中起着关键作用，为控制组件和外部设备提供稳定的电源。

二、主要特点

1. 设计与应用：
• 这两款模块均包含EPSM（励磁机电源模块）的两个主要部分：降压调节器和推挽式逆变器。
• 降压调节器负责将输入电压转换为50V直流中间电压，而推挽式逆变器则基于该中间电压生成必要的多个输出电压。
• 推挽式逆变器的变压器在输入电压源和控制系统的输出之间提供高压隔离，确保系统的安全稳定运行。
2. 电源供应：
• IS200EPSMG1A主要用于励磁控制系统，将来自配电模块（PDM）的125V直流电压转换为EX2100励磁控制所需的电压。
• 它为控制组件背板提供+5V直流、15V直流和24V直流电源，并为风扇、灭磁模块、撬棒模块等外部设备供电。
• IS200EPSMG1ADC（尽管具体型号“ADC”在参考文章中未详细说明，但基于命名习惯，可能代表某种特定配置或版本）的功能与IS200EPSMG1A类似，但可能具有特定的应用或配置差异。
3. 安装与连接：
• 在控制柜中，IS200EPSMG1A安装在励磁机电源背板（EPBP）上，该背板位于EBKPG A励磁机背板（EBKP）的下方。
• 电源通过连接器P1和P2（用于连接EBKP和其他板的电缆）从EPSMG1传输到EPBP。

IS200EPSMG1A and IS200EPSMG1ADC Digital 32 point excitation power module introduction

I. Overview

The IS200EPSMG1A and IS200epSMG1ADCs are digital 32-point excitation power modules developed by GE based on the Mark VI Turbine Control System. Both modules play a key role in the excitation control system and regulator control, providing a stable power supply to control components and external devices.

Two, the main characteristics

Design and Application:

Both modules contain the two main components of the EPSM (exciter Power Module) : the step-down regulator and the push-pull inverter.

The step-down regulator is responsible for converting the input voltage to a 50V DC intermediate voltage, while the push-pull inverter generates the necessary multiple output voltages based on this intermediate voltage.

The transformer of the push-pull inverter provides high voltage isolation between the input voltage source and the output of the control system, ensuring the safe and stable operation of the system.

Power supply:

The IS200EPSMG1A is primarily used in excitation control systems to convert the 125V DC voltage from the power distribution module (PDM) to the voltage required for EX2100 excitation control.

It provides +5V DC, 15V DC, and 24V DC power to the backplane of the control component, and supplies power to external devices such as fans, magnetic disconnection modules, and pry bar modules.

The IS200EPSMG1ADC (although the specific model "ADC" is not specified in the reference article, but may represent a particular configuration or version based on naming conventions) functions similarly to the IS200EPSMG1A, but may have specific application or configuration differences.

Installation and connection:

In the control cabinet, the IS200EPSMG1A is mounted on the exciter source backplane (EPBP), which is located below the EBKPG A exciter backplane (EBKP).

Power is transmitted from EPSMG1 to EPBP via connectors P1 and P2 (cables for connecting EBKP to other boards).
