磁阀式高压固态软起动装置在大功率同步电机中的应用

Application of Magnetic Valve Type High-voltage Solid Soft Starting Device for High Power Synchronous Motor

韶钢5号烧结主抽风机原采用水电阻起动,投运已近十年,设备老化,起动极不稳定,起动时间长.为了保证烧结设备生产长周期稳定、可靠、安全运行,提升起动可靠性,更换水电阻起动装置为磁阀式高压固态软起动装置,更新后运行状况良好,各项指标均能达到要求,为高炉生产稳定运行提供了可靠保障.

The main fan for the sintering machine #5 at SGIS with a water resistance starting had been in operation for near- ly ten years, the aging of equipment made the starting very unstable, and the start time was long. In order to ensure the sintering equipment could run stably, safely and reliably for a long time, the water resistance starting device had been re- placed with the magnetic valve type high-voltage solid soft starting device. After the replacement, it runs smoothly with all indexes meeting the requirements, providing a reliable guarantee for the stable operation of BFs.
