Microcomputer controlled excitation apparatus for synchronous machine

Synchronous machine excitation combined tanks	3、When synchronous machine starts or stops, the field is eliminated automatically avoiding inducing over voltage.     4、Adjusting manually field voltage、current and so achieving to adjust power factor.     5、Excellent out of step protection and automatic regulation reloading.     6、Structure is rational, figuration beautiful, volume small, noise low, convenient to use, maintenance easy. Technique guide line:     Input voltage:     three-phase four-wire system 380V±10%     Rated output voltage:     50V、75V、110V、140V、170V     Rated output current:     200A、300A、450A、600A     Model introduction:     HRKLF11 and HRKLF12     HR-company abbreviation K-thyristor rectifier L-field  F-forced wind cooling 1-synchronous machine special symbol     The system characteristic symbol as follow:     1－full voltage or reduced voltage start, constant field     2－full voltage or reduced voltage start, adjusting field according to load, dynamic braking	Application 1 Application 2
Application:      support for 200-1000kW synchronous machine, used to mine ball mill, smelting blower, associated compressor in chemical fertilizer factory, refrigerator for cold storage, synchronous machine for rolling mill and so on. Main advantages::     1、Control section adopts,the number of control boards is reduced to one from several, improving control precision and reliability.     2、Replacing control board without stopping machine, advancing system reliability.
