减少晃电对高压煤浆泵影响的措施

Measures for Decreasing Effect of Fluctuating Current on High-Pressure Coal Slurry Pump

电网电压波动时,变频器保护跳闸,使高压煤浆泵跳车,导致气化炉停炉,制约生产装置的长周期稳定运行。通过设置直流支撑装置和抗晃电接触器,在系统电压波动时起到了保护作用,保证了高压煤浆泵的稳定运行。

When the power grid voltage fluctuates, the protective device of the frequency converter trips, and the high-pressure coal slurry pump closes down, leading to the shutdown of the gasifier, thus restricting the stable long-cycle operation of the production equipment. The installment of a direct CUtTent supporter and a fluctuation resistant contactor plays a protective role when the voltage fluctuates in the system, ensuring the stable operation of the high-pressure coal slurry pump.
