无励磁机的励磁方式
Excitation mode without exciter
在励磁方式中不设置专门的励磁机，而从发电机本身取得励磁电源，经整流后再供给发电机本身励磁，称自励式静止励磁。自励式静止励磁可分为自并励和自复励两种方式。自并励方式它通过接在发电机出口的整流变压器取得励磁电流，经整流后供给发电机励磁，这种励磁方式具有结构简单，设备少，投资省和维护工作量少等优点。自复励磁方式除设有整流变压外，还设有串联在发电机定子回路的大功率电流互感器。这种互感器的作用是在发生短路时，给发电机提供较大的励磁电流，以弥补整流变压器输出的不足。这种励磁方式具有两种励磁电源，通过整流变压器获得的电压电源和通过串联变压器获得的电流源。
In the excitation mode, no special exciter is set, but the excitation power is obtained from the generator itself, and then supplied to the generator itself after rectification, which is called self excitation static excitation. Self excited static excitation can be divided into self shunt excitation and self compound excitation. The self shunt excitation mode obtains the excitation current through the rectifier transformer connected at the outlet of the generator and supplies the generator excitation after rectification. This excitation mode has the advantages of simple structure, less equipment, less investment and less maintenance work. In addition to rectifying and transforming voltage, the self compound excitation mode is also provided with a high-power current transformer connected in series in the stator circuit of the generator. The function of this kind of transformer is to provide large excitation current to the generator in case of short circuit, so as to make up for the shortage of rectifier transformer output. This excitation mode has two kinds of excitation power supply, the voltage power supply obtained by the rectifier transformer and the current source obtained by the series transformer.
