Practice on Protection and Improvement of Withstand Voltage Weighing Belt Coal Feeder

文章介绍了耐压称重式皮带给煤机的特性,通过对变频器参数修改实践,实现给煤机变频器故障保护自动恢复,提高给煤机运行的可靠性,消除电源意外扰动对给煤机的影响,保障锅炉安全持续稳定运行。

This paper introduces the traits of withstand voltage weighing belt coal feeder. According to the modification and practice of parameters of the frequency converter, when there is a malfunction, the automatic recovery of the frequency converter of coal feeder can be achieved. The reliability of the coal feeder＇s operation will be improved, and the effects of the accident power supply perturbation on the coal feeder can be eliminated. Eventually, the safety and stability of the boilers can be guaranteed.
