IS200EPSMG1A與IS200EPSMG1ADC數(shù)字量32點勵磁電源模塊介紹

一、概述

IS200EPSMG1A和IS200EPSMG1ADC是由GE公司根據(jù)Mark VI渦輪機控制系統(tǒng)開發(fā)的數(shù)字量32點勵磁電源模塊。這兩款模塊在勵磁控制系統(tǒng)和調(diào)節(jié)器控制中起著關(guān)鍵作用，為控制組件和外部設(shè)備提供穩(wěn)定的電源。

二、主要特點

1. 設(shè)計與應(yīng)用：
• 這兩款模塊均包含EPSM（勵磁機電源模塊）的兩個主要部分：降壓調(diào)節(jié)器和推挽式逆變器。
• 降壓調(diào)節(jié)器負責(zé)將輸入電壓轉(zhuǎn)換為50V直流中間電壓，而推挽式逆變器則基于該中間電壓生成必要的多個輸出電壓。
• 推挽式逆變器的變壓器在輸入電壓源和控制系統(tǒng)的輸出之間提供高壓隔離，確保系統(tǒng)的安全穩(wěn)定運行。
2. 電源供應(yīng)：
• IS200EPSMG1A主要用于勵磁控制系統(tǒng)，將來自配電模塊（PDM）的125V直流電壓轉(zhuǎn)換為EX2100勵磁控制所需的電壓。
• 它為控制組件背板提供+5V直流、15V直流和24V直流電源，并為風(fēng)扇、滅磁模塊、撬棒模塊等外部設(shè)備供電。
• IS200EPSMG1ADC（盡管具體型號“ADC”在參考文章中未詳細說明，但基于命名習(xí)慣，可能代表某種特定配置或版本）的功能與IS200EPSMG1A類似，但可能具有特定的應(yīng)用或配置差異。
3. 安裝與連接：
• 在控制柜中，IS200EPSMG1A安裝在勵磁機電源背板（EPBP）上，該背板位于EBKPG A勵磁機背板（EBKP）的下方。
• 電源通過連接器P1和P2（用于連接EBKP和其他板的電纜）從EPSMG1傳輸?shù)紼PBP。

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).
