上海韓施電氣代理施耐德EOCR電機保護器
上海韓施電氣提醒大家,使用電動機保護器時必須注意控制線路的接線問題,以確保正常運行。一旦線路異常了也不要擔心,可以通過以下幾種方法排除:
1、試送投運法
主要查找剩余電動機保護器自身故障。
具體操作方法是:先切斷,再將剩余電動機保護器的零序負荷側引線全部拆除(二級、三級剩余電流動作保護器直接將出線拆除)再合保護器。若保護器仍然無法投運,則說明保護器自身故障,應予以修理或更換。
若能正常運行,則保護器本身并*,再查找配電盤或者線路。其操作方法是:先將各路出線或交流負荷切斷,若不能運行則說明配電盤上有故障,應檢查各路、儀表等設備是否絕緣良好,接線是否正確;若能正常運行則說明配電盤上*。當確認故障發生在外線路上時,可采用分線查找法查找故障點。
2、直觀巡查法
就是巡視人員針對故障現象進行分析判斷,對保護區域包括剩余電動機保護器和被保護的線路設備等進行直觀巡視,從而找出故障點。巡視時應著重對線路的轉角、分支、交叉跨越等復雜地段和故障點進行檢查。這種方法簡便易行,適用于對明顯故障點的查找。如導線斷線落地、拉線與導線接觸及錯誤接線等。
3、數值比較法
就是借助對線路或設備進行測量,并把所測的數值與原數值進行比較,從而查出故障點。需要特別指出的是:當線路中性線絕緣下降或設備中性線重復接地,容易引起保護頻繁跳閘,而二級保護器不跳閘。在解決二級保護器跳閘時,不應采取將相線與中性線對調的方法投運二級保護,將設備重復接地線拆除即可。
4、分線排除法
上海韓施電氣建議排查線路故障點時,可以按照“先主干、再分支、后末端"的順序,斷開低壓電網的各條分支線路,僅對主干線進行試送電,若主干線*,那么主干線便能正常運行。然后,再依次將分支和末端投入運行。哪條線路投入運行時電動機保護器跳閘,故障點就在哪條線路上,就可在此線路上集中查找故障點。
