同步电动机励磁装置改造后的效果探讨

Effect After the Synchro Motor Silicon Controlled Rectifier Excitation Device Reformed is Discussed

结合济三煤矿对通风机要求的实际情况,对同步电动机可控硅励磁装置进行了改造,取得了给定范围内调整励磁参数、电动机不会失步、励磁装置不会失控等较好的效果,确保了同步电动机的安全可靠运行。

Unifies jining No.3 coal ore theactual situation which requests to the ventilator, has arried on thetransformation to the synchronous motor silicon-controlled rectifierexcitation installment, obtained has as-signed in the scope to adjustthe excitation parameter, the electric motor cannot fall out of step, the excitation installment could not lose control and so on a bettereffect, has guaranteed the synchronous motor security reli-ablemovement.
