近几年来,可控硅励磁装置应用于同步电动机励磁日益普遍。目前使用较多的有KGLF_(11)型和KGLF型。其电路型式,前者为三相全控励磁电路,后者为三相半控励磁电路。KGLF_(11)型适于同步电动机的重载启动(当然也适于空载启动),但电路较复杂,造价也较高。KGLF型比KGLF_(11)型虽然电路简单,维护调试较省事,造价较低,但它不适于同步电动机的重载启动(如球磨机),也不适于象矿井通风机这类负载(其负荷随转速升高而增大)启动。拖动通
In recent years, the SCR excitation device used in synchronous motor excitation increasingly common. Currently used more KGLF_ (11) and KGLF type. The circuit type, the former is three-phase full-controlled excitation circuit, which is three-phase half-controlled excitation circuit. KGLF_ (11) type is suitable for heavy-duty starting of synchronous motor (of course, it is suitable for no-load starting), but the circuit is more complex and the cost is higher. KGLF type KGLF type (11) Although the circuit is simple, maintenance and debugging more economical, lower cost, but it is not suitable for heavy-duty synchronous motor start (such as ball mill), is not suitable for mine fans and other such loads Speed increase and increase) start.
