摘要
针对变频软启动在工程应用中存在的问题,分析了变频器依次启动多台电动机的切换问题,提出一种采用变频器和软启动器共同控制的恒压供水软启动系统,达到了较好的软启动效果,实现了泵控节能目的。
The problem of Switch-over was analyzed while frequency converter successively starting multi-sets of electromotor,and constant pressure water supply soft starting system controlled by both converter and soft starter was then developed.The system achieved effectively the soft starting and energy saving.
