詳細說明
    啟動時間可以根據(jù)不同的負載進行設(shè)定,對啟動時間進行佳優(yōu)化,在該時間范圍內(nèi),電動機轉(zhuǎn)速緩慢上升, 具有缺相,三相不平衡,過載,過流等電機的保護。性價比高,操作簡單, 體積小,重量輕,安裝調(diào)試方便, 具有可控硅過熱和過電壓保護。 沒采用軟啟動器之前設(shè)備存在的問題 連軋廠冷剪機采用(星/ 三角) 轉(zhuǎn)換啟動裝置。連軋廠冷剪機所帶的飛輪重負載、大直徑,在啟動和停車過程中慣性大,切換瞬間出現(xiàn)高電流尖峰,電動機在啟動時的沖擊電流對電網(wǎng)電壓波動也帶來很大的影響,同時對控制設(shè)備產(chǎn)生很大的損害,經(jīng)常燒接觸器,需要經(jīng)常進行更換,嚴(yán)重影響生產(chǎn)。連軋廠的冷剪機在啟動時出現(xiàn)故障會造成全線停產(chǎn)。如果僅僅為啟動電機而配電容量,顯然不可取。傳統(tǒng)的降壓啟動沒有從根本上解決問題。 改造后采用的軟啟動器啟動 軟啟動器是一種集軟啟動、軟停車、輕載節(jié)能和多功能保護于一體的電機控制裝備。實現(xiàn)在整個啟動過程中無沖擊而平滑的啟動電機,而且可根據(jù)電動機負載的特性來調(diào)節(jié)啟動過程中的各種參數(shù),如限流值、啟動時間等。
