摘要
针对目前变频恒压供水系统中多泵变频循环软起动设计方案对变频器、电机和供水系统的影响进行深入分析,指出其局限性和严重的危害的。并提出变频输出切换技术发展方向,即变频器和工频电网之间的同步切换控制技术。
Analyse the influence of multiple pump freqency transforming cyclical soft starting design plan on frequency transformer,motor and water supply system.piont out the limitations and serious harmfulness of the design plan and the development direction of frequency transforming output switching technique,the technique is a synchronous switching control technique between frequency transformer and power frequency electric network.
