要切換到旁路運(yùn)行狀態(tài),如何平滑地切換到運(yùn)行狀態(tài),這也是軟啟動(dòng)器的一個(gè)難點(diǎn),如何選準(zhǔn)旁路點(diǎn)非常重要。旁路點(diǎn)早了,電流沖擊非常大,即使在低壓條件下,也會(huì)造成三相電源中斷路器跳閘,甚至?xí)p壞斷路器。高壓條件下危害更大。旁路點(diǎn)遲了,電機(jī)抖動(dòng)得厲害,影響負(fù)載正常工作。因此,旁路信號(hào)的硬件檢測(cè)電路必須非常,并且程序處理也要恰到好處。維修檢查編輯平時(shí)注意檢查軟起動(dòng)器的環(huán)境條件,防止在超過其允許的環(huán)境條件下運(yùn)行。注意檢查軟起動(dòng)器周圍是否有妨礙其通風(fēng)散熱的物體,確保軟起動(dòng)器四周有足夠的空間(大于150mm)。定期檢查配電線端子是否松動(dòng),柜內(nèi)元器件有否過熱、變色、焦臭味等異?,F(xiàn)象。定期清掃灰塵,以免影響散熱,防止晶閘管因溫升過高而損壞。

一旦輸出短路或嚴(yán)重過載時(shí)間超出幾百毫秒將導(dǎo)致二極管(通常為肖特基二極管)過熱損壞;其二,當(dāng)由于某種原因,比如人為關(guān)閉,使開關(guān)振蕩電路停止工作,負(fù)載端仍然有電壓存在,只是比輸入端低一個(gè)二極管的管壓降而已,這時(shí)輸出仍會(huì)消耗能量。除此之外,如果該殘存電壓低于負(fù)載穩(wěn)態(tài)工作電壓范圍,將使電路處于不確定狀態(tài)。對(duì)于輸出電流相對(duì)較小的應(yīng)用場(chǎng)合(小于5A),利用單片電流模式控制器和高端電流取樣技術(shù),上述兩個(gè)問題都可以很好地解決。在這些電路中,二極管被一同步整流開關(guān)三極管取代,因此通過關(guān)閉內(nèi)部開關(guān)三極管就可把輸入輸出通路截?cái)?,這樣一來,負(fù)載端對(duì)輸入端來說就呈高阻狀態(tài),而這正是所希望的結(jié)果。在正常工作狀態(tài),電路內(nèi)部的高端取樣電阻對(duì)負(fù)載電流周期性地進(jìn)行采樣。
