变频调速控制系统的设计与安装

Design and installation of frequency converter

为了解决"由于变频控制系统在设计、安装中存在诸如元件布置不合理、导线排列不规范、通风不畅等现象,从而导致变频控制系统运行不稳定,出现故障而停机"的问题,对变频器控制系统的理论、设计、元件安装和布置进行了分析,着重对变频器通风路径的选择、散热问题进行了分析,提出了解决变频控制系统不稳定的方法。实践结果表明,按该方法安装的变频器控制系统降低了运行故障率,提高了系统稳定性。

Aiming at solving problems that the frequency conversion control system in the design, installation of the existence of such component layout unreasonable, conductor arrangement is not standardized, poor ventilation and other phenomena, which leads to the frequency conversion control system instability, failure and downtime, the inverter control system theory, design, component mounting and arrangement were explored, mainly the converter ventilation path selection, heat dissipation problems were analyzed. The method to solve the unstabitily of frequency control system was put forward. Practice running result shows that, according to this method, the installation of frequency converter control system fault rate is reduced, it greatly improves the stability.
