(7)检查变频器交流输入电压是否超过大值。极限是418V(380V×1.1),如果主电路外加输入电压超过极限,即使变频器没运行,也会对变频器线路板造成损坏。
2.2定期检查
利用每年一次的大修时间,将检查重点放在变频器日常运行时无法巡视到的部位。
(1)作定期检查时,操作前必须切断电源,变频器停电后待操作面板电源指示灯熄灭后,等待4min(变频器的容量越大,等待时间越长,*长为15min)使得主电路直流滤波电容器充分放电,用万用表确认电容器放电完后,再进行操作。
(2)将变频器控制板、主板拆下,用毛刷、吸尘器清扫变频器线路板及内部IGBT模块、输入输出电抗器等部位。线路板脏污的地方,应用棉布沾上酒精或中性化学剂擦除。
(3)检查变频器内部导线绝缘是否有腐蚀过热的痕迹及变色或破损等,如发现应及时进
