变频器在电厂锅炉给水电气控制系统上的应用

Application of Frequency Inverter in Water-supply Electric Control System of Power Plant Boiler

电厂锅炉给水系统是采用集中母管制手动调节的方式,为更好地让锅炉给水稳定,我们对锅炉的给水系统进行了恒压给水改造.采用变频器控制.在改造中,我们根据原给水电控系统的要求和功能,将变频器电控系统很好的与原电控系统结合起来,既满足了恒压供水的电气要求,又使操作与原来的方式一样,方便了工人的操作。

To realize the stability of boiler water supply,the authors make transformation of water supply with constant pressure on centralized manually-adjusted water-supply system by frequency inverter,in which the electric control system with frequency inverter is well combined with the original electric control system to meet the electric requirements for water supply with constant pressure and make the operation the same as the original way and convenient for the workers.
