摘要
针对当前变频调速控制系统设计中因选配电抗器不规范而导致系统工作运行不稳定的问题,对变频调速控制系统选用各类配套的附加电抗器的依据和方式进行了研究。在实践经验和电路分析的基础上阐释了附加电抗器的意义和作用,根据有关电路计算结果给出了改进型无线电干扰抑制电抗器、交变直整流后的电源侧交流电抗器、提高功率因数的直流电抗器的设计选型要点;并提供了具体的附加电抗器设计与选配方案推荐表。多次实验结果表明,按该方案对不同功率型号变频器所配套的各类电抗器在变频调速控制系统中工作稳定、可靠,提高了系统功率因数,对降低电动机的温升和噪音起到了积极作用。
Aiming at the problem that the frequency control of motor speed control system runs unstably caused by the non-standard selection of the reactor,the basis and the way to form a complete set of additional reactor were studied.On the basis of practical experience and circuit analysis the significance and function of additional reactor were illustrated,the design and selection of DC reactor were presented according to the relevant circuit calculations of radio interference suppression reactor,alternating straight after rectifying power supply side AC reactor,improving the power factor of the gist.And the specific additional reactor design and the selection scheme recommendation table were provided.Experimental results show that different models of inverter power supporting various types of reactor in the frequency control of motor speed control system can work stably and reliably,to improve the system power factor and reduce the temperature rise and noise of the motor.
