檢查維修方法
1、檢查電動機是否發(fā)熱,如果電動機溫升不高,則應先檢查變頻器的電子熱保護功能設置的是否合理。如變頻器尚有裕量,則應調(diào)大電子熱保護功能的預設值。
如果電動機的溫升過高,這時的過載是屬于正常過載,則說明是電動機負荷過重。這時,首先應看能否適當加大傳動比,以減輕電動機軸上的負荷。如能夠加大,則加大傳動比;如果傳動比無法加大,則應加大電動機的容量。
2、檢查電動機側(cè)三相電壓是否平衡,如果電動機側(cè)的三相電壓不平衡,則應再檢查變頻器輸出端的三相電壓是否平衡,如果也不平衡,則問題在變頻器內(nèi)部發(fā)生故障,就必須對變頻器維修。
如果電動機側(cè)三相電壓平衡,則應了解跳閘時的工作頻率。如果工作頻率較低,又未用矢量控制(或無矢量控制),則首先降低V/f比。如果降低后仍能帶動負載,則說明原來設置的V/f比過高,勵磁電流的峰值偏大,可通過降低V/f比來減小電流;如果降低后帶不動負載了,則應考慮加大變頻器的容量;如果變頻器有矢量控制功能,則應采用矢量控制方式。
