變頻控制柜的維修保養

2018-10-11

 

1、變頻控制柜斷開電源,檢查機架是否有可靠的接地,并使接地電阻不大于4Ω。

2、變頻控制柜上有不同性質的電壓(直流110V;交流單相220V;三相交流),在維修保養時必須分清電路,防止發生短路事故。

3、變頻控制柜上的全部電器開關,應動作靈活可靠,無顯著噪聲,連接線結頭和接線柱應無松動現象,動觸頭連接線結頭處鋼絲應無斷裂現象。TDL-2000 發電機勵磁柜3.JPG

4、用軟刷或吹風清楚屏板插件和全部電磁開關零件的積塵,并檢查變頻控制柜內電器開關觸頭的狀態,接觸情況,線圈外表的絕緣以及機械部件的動作是否可靠。TDL-2000 發電機勵磁柜2.JPG

5、變頻控制柜更換熔絲時,應使熔斷電流與該回路的電流相匹配。
