IC670ALG310
通用变频器一般为电压型变频器,采用交—直—交工作方式,由于直流侧的平波电容容量较大,在变频器接入电源的一瞬间充电电流很大,可能导致电源开关跳闸,为此在充电回路中设置一个起动电阻来限制充电电流,而在充电完成后,控制电路通过接触器的触点或晶闸管将电阻短路。充电电路故障一般表现为起动电阻被烧坏,变频器报警显示为直流母线电压故障。当变频器的交流输入电源频繁通断时,或者短路接触器的触点接触不良或晶闸管的导通阻值变大时,都会导致起动电阻被烧坏。如遇这种情况,可购买同规格的电阻更换。同时找出烧坏电阻的原因,如果故障是由输入电源频繁通断引起的,这种现象,如果故障是由短路接触器触点或短路晶闸管引起,则更换这些元器件,才能再将变频器投入使用。
