KGLF11-300／75可控硅励磁装置在深部铜矿三台100m3／min空压机上应用5年，有效保护了同步电动机处于正常运行状态，但是实践也证明，先进的技术装备必须首先要认识、了解并掌握它的基础工作原理，通过使用去进一步完善，才能使其发挥应好作用，取得最佳效果。
The application of KGLF11-300 / 75 thyristor excitation device to three 100m3 / min air compressor in deep copper mine for 5 years has effectively protected the synchronous motor in normal operation, but the practice also proves that advanced technology and equipment must first recognize , Understand and master its basic working principle, through the use to further improve in order to make it play a good role, to obtain the best results.
