ABB-APFS-11C ABB 电源主板 驱动电路

AFPS-11C电源主板AFPS-11C

制造商:ABB

产品编号:68969972

ABB型号名称:电力SUPP AFPS-11C

目录描述:AFPS-11C电源主板

电源主板是电源内部的主要组件，负责将交流电转换为直流电，为整个系统提供稳定的供电。

ABB-APFS-11C电源主板主要由输入、输出、驱动电路等组成，其中输入电路包括整流滤波电路、功率因数校正电路等，输出电路包括主变换电路、输出滤波电路等，驱动电路包括PWM控制芯片、驱动信号放大器等。

ABB-APFS-11C安装和配置电源主板的步骤如下：

将电源放入机箱内，注意电源放入的方向，有些电源有两个风扇，或者有一个排风口，则其中一个风扇或排风口应对着主板。

将电源上的螺丝固定孔与机箱上的固定孔对正，拧上一颗螺丝固定住电源。

将最后三颗螺丝孔对正位置，再拧上剩下的螺丝即可。

ABB-APFS-11C检查电源是否正常的方法有：

检查电源背面的散热风扇是否不转。若是散热风扇不转，则表明电源已坏。

计算机主机面板上的电源指示灯是否不亮。若是电源指示灯不亮，则表明电源没有供电。

启动时是否听不到软驱、硬盘或光驱在工作的声音。若是听不到工作声音，则表明电源根本没有供给它们。

A8B为全球首条110千伏特高压工程供应的变压器及关键设备经过型式突验，书写电力前史新篇章A8B近日成功测试了包括高姗和低姥变压器在内的全球大功率110千伏特高压直流 压器，再次书写了全球电力前史的新篇章。该变压器由A8B与电网公司共同开发和出产，将应用在昌吉-古泉11⒁特高压直流线路中。该线路将新疆的电力输送到安徽，成功h经过的一系列型式实验为该线债的完工打下了坚实的报底。我国的用电负荷会集在东部，而许多的动力资源敏布在西部和西北部。不断增加的用电需求椎动了特高压线债的建造，然后增加输电才干、削喊损耗。昌吉∵古泉特高压直流蛐电纺路是全球条±1100千伏特高压直流线路，在电压等级、输电容量和间隔上都创下了新的世界记载。

AFPS-11C Power supply mainboard AFPS-11C

Manufacturer :ABB

Product number :68969972

ABB Model name: Power SUPP AFPS-11C

Catalog Description :AFPS-11C power board

The power board is the main component inside the power supply and is responsible for converting alternating current into direct current to provide stable power supply for the entire system.

ABB-APFS-11C power supply board is mainly composed of input, output, drive circuit, etc. The input circuit includes rectifier filter circuit, power factor correction circuit, etc. The output circuit includes main conversion circuit, output filter circuit, etc. The drive circuit includes PWM control chip, drive signal amplifier, etc.

The steps for installing and configuring the ABB-APFS-11C are as follows:

Put the power supply into the chassis, pay attention to the direction of the power supply into the chassis. Some power supplies have two fans, or there is an exhaust outlet, one of the fans or exhaust outlet is facing the motherboard.

Align the screw holes on the power supply with those on the chassis, and tighten a screw to secure the power supply.

Align the last three screw holes and screw on the remaining screws.

ABB-APFS-11C check whether the power supply is normal in the following ways:

Check whether the heat dissipation fan at the back of the power supply does not work. If the cooling fan does not turn, it indicates that the power supply is broken.

Whether the power indicator on the main panel of the computer is off. If the power indicator is off, it indicates that there is no power supply.

Check whether the FDD, hard disk, or CD-ROM drive cannot be heard during startup. If the working sound is not heard, it indicates that the power supply is not supplied to them at all.

A8B for the world's first 110 kV UHV project to supply transformers and key equipment through the type of sudden test, writing a new chapter in the history of power A8B recently successfully tested the world's high-power 110 kV UHV DC transformer, including Gaoshan and low voltage transformers, once again writing a new chapter in the history of global power. The transformer is jointly developed and produced by A8B and power grid Company, and will be applied in Changji-Guquan 11 (14) UHV DC line. The line will be Xinjiang power transmission to Anhui, h through a series of successful type tests for the completion of the line debt laid a solid report. China's electricity load will be concentrated in the east, while many power resources are distributed in the west and northwest. The increasing demand for electricity has led to the construction of UHV line debt, which in turn increases transmission capacity and cutting losses. Changji Guquan UHV DC electrical circuit is a global ±1100 kV UHV DC circuit, which sets a new world record in voltage level, transmission capacity and interval.
