河南商水县周口电机厂职工在党委的正确领导和省电业局的技术指导之下,经过克苦钻研和多次试验,试制成功了一台三相机械整流自激磁发电机。经过试验鉴定,这台发电机容量为10瓩,三相50周/秒,电压400/230伏,电流18.1安培;激磁电压200伏,激磁电流3安培,转速1,500转/分,运转质量良好。发电机型式为卧轴防滴式;转子为磁极,定子为电框绕组。一般交流发电机需要独立的励磁机供给激磁电流,但励磁机的制造比较困难,在维护上也比较复杂。机械整流发电机不需要励磁机,它的激磁电流是利用交流发电机发出的一部份电流,经过整流环整流以后变成直流电,送入转子磁场进行激磁。机械整流
Henan Shangshui Zhoukou Electric Machinery Factory under the leadership of the party committee and the provincial power industry under the guidance of technical guidance, after painstaking research and many tests, trial success of a three-phase motor rectifier self-excited magnetic generator. After testing, this generator has a capacity of 10 瓩, three phases of 50 cycles / second, voltage of 400/230 volts and current of 18.1 Amps. Excitation voltage of 200 V, excitation current of 3 A, rotation speed of 1,500 rpm, good running quality. Generator type for horizontal shaft anti-drip; rotor for the pole, the stator winding frame. The general alternator needs an independent exciter to supply the excitation current, but the exciter is more difficult to manufacture and more complicated in maintenance. Mechanical rectifier generator does not require exciter, the excitation current is generated by the use of alternator part of the current, after commutation rectifier into DC, into the rotor magnetic field excitation.
