可控硅恒压励磁调节器主要用于75千瓦同步发电机作恒压设备,可控制同步发电机的励磁机的励磁绕组电流,可控制硅通过2～3安培电流。当同步发电机电压变化时,反馈讯号使可控硅导通角移前,发电机励磁加强或削弱,以维持发电机电压恒定。在启动30千瓦以上电动机时,仍可使电压恒定。在柴油机速度由1500转/分降至1200转/分时,则发电机电压由400伏降至370伏左右。调节器于一九七五年七月完成,适用于中、小厂矿自行发电,维持厂内电压恒定。可以
SCR constant voltage excitation regulator is mainly used for 75 kilowatts synchronous generator as a constant voltage equipment, can control the synchronous generator excitation machine excitation winding current, silicon can be controlled by 2 to 3 amperes of current. When the synchronous generator voltage changes, the feedback signal to the SCR conduction angle before the generator excitation to strengthen or weaken to maintain the generator voltage is constant. The voltage can still be constant when starting a motor with more than 30 kW. When the diesel engine speed is reduced from 1500 rpm to 1200 rpm, the generator voltage drops from 400 volts to about 370 volts. The regulator was completed in July 1975, suitable for medium and small factories and mines to generate electricity to maintain the factory voltage. can
