矸石电厂2#发电机改换励磁系统简述

An Introduction to Transformation of the Excitation System for a Dynamo

近几年来,由于新技术、新工艺和新器件的涌现和使用,使得发电机的励磁方式得到了不断的发展和完善,大幅度地提高了电厂的工作效率。本文就矸石电厂2#发电机改造前后的励磁系统做一简单阐述。

In order to realize transformation of electric energy , a direct current magnetic field is necessary for a synchronous dynamo , and the direct current which results in the direct current magnetic field , is called an excitation electric current. In light of the means of excitation electric current provided , those dynamos which gained excitation electric power from itself and other sources , are called a separate excitation dynamo and the self - driven dynamos . The 2# dynamo should be transform from the a separate excitation system into the self- driven dynamos .
