发电机励磁自动调节系统(CAP)由以下部件组成:励磁机B、内反馈磁放大器A、同步副励磁机CIIB、分配变压器TP、给定环节Б3y、直流电流互感器TT、直流电压互感器TH、感应传感器ИД、整流桥ΠB1-ΠB3和许多可调电阻(电路图详见苏联1980年第6期插图)。为便于了解CAP的工作原理,让我们来研究CAP中某些部件的作用原理,这些部件在颇大程度上决定了整个调节系统的特性。内反馈磁放大器
Generator excitation automatic regulation system (CAP) is composed of the following components: exciter B, internal feedback magnetic amplifier A, synchronous secondary exciter CIIB, distribution transformer TP, given link Б3y, DC current transformer TT, DC voltage transformer TH , Inductive sensor ИД, rectifier bridge ΠB1-ΠB3 and many adjustable resistors (circuit diagram see the Soviet Union in 1980 No. 6 illustrations). For a better understanding of the working principle of CAP, let us examine the principle of some components in the CAP, these components to a large extent determine the characteristics of the entire regulatory system.
