ABB DSQC 266A 3HAB8796-1机器人系统PLC/DCS备件

1、ABB DSQC 266A电源:为励磁功率整流单元提供电源(自并励励磁系统一般采用励磁变的方式)

2、功率整流:指向同步发电机转子绕组提供直流励磁电流的部分。

3、ABB DSQC 266A调节控制器:根据控制要求的输入信号和给定的调节准则控制励磁功率单元输出的装置它感受发电机电压和运行工况的变化，自动的调节励磁功率单元输出的励磁电流的大小，以满足系统运行的要求

4、灭磁及起励:灭磁的作用是当发电机内部及外部发生诸如短路及接地等事故时迅速切断发电机的励磁，并将蓄藏在励磁绕组中的磁场能量快速消耗。起励的作用是为发电机转子绕组提供起始的励磁电流

5、ABB DSQC 266A发电机转子:为发电机提供励旋转磁场

1, ABB DSQC 266A power supply: provide power for the excitation power rectifier unit (self-shunt excitation system generally adopts the way of excitation change)

2, power rectification: the part that provides DC excitation current to the rotor winding of the synchronous generator.

3, ABB DSQC 266A regulation controller: according to the control requirements of the input signal and the given regulation criteria to control the excitation power unit output device it feels the generator voltage and operating conditions change, automatically adjust the excitation power unit output current size, in order to meet the requirements of the system operation

4, magnetization and excitation: the role of magnetization is to quickly cut off the excitation of the generator when the internal and external accidents such as short circuit and grounding occur, and the magnetic field energy stored in the excitation winding is rapidly consumed. The role of excitation is to provide the initial excitation current for the rotor winding of the generator

5, ABB DSQC 266A generator rotor: for the generator to provide exciting rotating magnetic field
