勵磁柜需要注意哪些問題

2018-09-12

 

小編給大家介紹一下勵磁柜需要注意哪些問題

必須首先保證斷路器常開輔助接點接觸良好;

初次并網后“并網指示”燈在閃爍,并不代表接線一定有誤;

初次并網后“并網指示”燈長亮,并不代表接線一定正確;TDL-5勵磁柜.jpg

并網后如果“并網指示”燈長亮,發電機功率因數調節正常。恭喜:可以正常發電!

并網后如果“并網指示”燈長亮,但電流不斷自動加大時請迅速按住“減”鍵降低電流后,解列分閘停機,并將兩根電流輸入線對調后再試。   勵磁柜

初次并網后“并網指示”燈在不斷閃爍,請先增加有功負荷到10%左右,同時使用“增”鍵增加一定的無功負荷。在帶上10%左右負荷的情況下,按“切換”鍵,檢查發電機電壓如果大于電網電壓約8V-15V!說明接線正確!這時請人為將參數HP設定為HPNO后重新并網即可解決問題。配電柜1.jpg

檢查接線正確但是并網指示紅燈閃爍,說明功率因數接線同名端自動確認失敗,引起控制器錯誤判斷同名端的原因大多是并網瞬間發電機電流反向。一般為并網同期誤差造成。  勵磁柜

 控制器自動確認功率因數接線同名端成功并網指示紅燈長亮,控制器會自動作出處理,無需人為干預。
