风机变频器抗“晃电”技术改造

ANTI-INTERFERENCE TECHNOLOGY MODIFICATION FOR FREQUENCY TRANSFORMER OF BLOWER

针对甲醛生产装置中罗茨鼓风机变频器遇"晃电"跳车的问题,通过采用DZQ-B抗"晃电"技术,结合变频器"再启动"功能对控制回路进行改造。实际运行表明能够有效解决供电系统"晃电"对变频器造成的影响,保证装置的安全稳定运行。

The interference electricity in frequency transformer caused Root blower tripped in formaldehyde plant. The control loop was modified by using DZQ-B anti-interference technology in connection with frequency transformer ＂restart＂ function. The modification effectively solved the problems and reassured the plant running in safe and steady mode.
