主要电气设备

Main electrical equipments
为了满足用电设备对电力的要求和保证电力系统运行的 安全稳定和经济性,发电厂电
气部分的主要工作是启、停机组,调整负荷,切换设备和线路,不断监视主 要设备的运行,
发生异常和故障时及时处理等。以上所有的工作都是靠操作主要电气设备来完成的。本厂
主要电气设备如下:

In order to satisfy the equipment

equipment and line, constant
survey major equipment, quickly react to failure or unusual situation, etc. The above missions are
completed by operation of major electrical equipment. The main electrical equipment in this plant
as follow:

1.1.1

汽轮发电机


发电机是根据电磁感应原理而 工作的一种旋转电气设备,它将机械能转变成电能。它
与汽轮机直接耦合传动。发电机旋转方向从汽轮机 端看为顺时针方向。

Generator
is
one
kind
of

柴油发电机


柴油发电机平时处于备用状态,当发生全厂停电事故时,自动 控制系统会自动隔离厂用
电母线和事故保安段母线,同时发出信号命令柴油发电机启动,柴油发电机自带 控制系统,
可以在
10-15s
内自动完成柴油启动、调速、升压、合闸一系列的过程 ,供电给事故保安段母
线,维持基本的设备运转,保障锅炉和汽机及其他辅助设备的安全停机。
