歡迎您的來(lái)電詢價(jià)。給我一次機(jī)會(huì),給您多一個(gè)選擇?。?!
軟起動(dòng)器是一種集電機(jī)軟起動(dòng)、軟停車、輕載節(jié)能和多種保護(hù)功能于一體的新穎電機(jī)控制裝置,國(guó)外稱為Soft Starter。它的主要構(gòu)成是串接于電源與被控電機(jī)之間的三相反并聯(lián)閘管及其電子控制電路。運(yùn)用不同的方法,控制三相反并聯(lián)閘管的導(dǎo)通角,使被控電機(jī)的輸入電壓按不同的要求而變化,就可實(shí)現(xiàn)不同的功能。
ABB PSS系列軟啟動(dòng)器有3個(gè)旋轉(zhuǎn)設(shè)定開關(guān)合一個(gè)2位撥動(dòng)開關(guān),對(duì)于各種不同的應(yīng)用場(chǎng)合都能完成基本的參數(shù)設(shè)定。
1.啟動(dòng)曲線——設(shè)定啟動(dòng)時(shí)電壓提升的時(shí)間
說(shuō)明:斜坡升壓軟起動(dòng)。這種起動(dòng)方式zui簡(jiǎn)單,不具備電流閉環(huán)控制,僅調(diào)整晶閘管導(dǎo)通角,使之與時(shí)間成一定函數(shù)關(guān)系增加。其缺點(diǎn)是,由于不限流,在電機(jī)起動(dòng)過(guò)中,有時(shí)要產(chǎn)生較大的沖擊電流使晶閘管損壞,對(duì)電網(wǎng)影響較大,實(shí)際很少應(yīng)用。啟動(dòng)時(shí)間可在1-30秒內(nèi)調(diào)整。
2.停止曲線——設(shè)定停止時(shí)間電壓下降的速度
說(shuō)明:電機(jī)停機(jī)時(shí),傳統(tǒng)的控制方式都是通過(guò)瞬間停電完成的。但有許多應(yīng)用場(chǎng)合,不允許電機(jī)瞬間關(guān)機(jī)。例如:高層建筑、大樓的水泵系統(tǒng),如果瞬間停機(jī),會(huì)產(chǎn)生巨大的“水錘”效應(yīng),使管道,甚至水泵遭到損壞。為減少和防止“水錘”效應(yīng),需要電機(jī)逐漸停機(jī),即軟停車,采用軟起動(dòng)器能滿足這一要求。軟起動(dòng)器中的軟停車功能是,晶閘管在得到停機(jī)指令后,從全導(dǎo)通逐漸地減小導(dǎo)通角,經(jīng)過(guò)一定時(shí)間過(guò)渡到全關(guān)閉的過(guò)程。停車的時(shí)間根據(jù)實(shí)際需要可在0 ~ 30s調(diào)整。
3.初始電壓/限流功能——設(shè)定啟動(dòng)曲線的開始電壓水平以及停止曲線的終止電壓水平
