摘要
本文以介绍SJVF-A变频器的保护为主线,对工作电源过电压、工作电源欠电压、瞬时停电保护、失速防止、过电流、过电压、过热、过负荷(电子热继电器)、抗干扰保护等通用型VVVF保护功能进行了讨论,对各种保护电路的工作原理和设计方法作了说明。
In this paper the protection of SJVF-A inverter is introduced as an example, various protective functions of VVVF inverter, such as overvoltage, undervoltage, momentary power failure, stall prevention, over-current, overheat protection. overload protection by electric thermal relay, and interference prevention are dis-cussed, the principle and design method of the protection are illustrated.
