近年來，電氣傳動跟控制技能的停止日新月異,PLC在機械設施德州剪板機主(zhu)動(dong)(dong)化控(kong)制中一(yi)大(da)量利用，新(xin)型(xing)的(de)馬達(da)(da)電(dian)(dian)(dian)(dian)子(zi)控(kong)制器(qi)(qi)（即(ji)軟啟動(dong)(dong)器(qi)(qi)）在大(da)功率三(san)相異(yi)(yi)步(bu)馬達(da)(da)的(de)限流起(qi)(qi)動(dong)(dong)中也(ye)結束一(yi)大(da)量利用。因(yin)為破(po)式(shi)剪(jian)板機主(zhu)拖動(dong)(dong)電(dian)(dian)(dian)(dian)機功率為37kW，需(xu)采取起(qi)(qi)動(dong)(dong)限流辦法，以減小起(qi)(qi)動(dong)(dong)直流電(dian)(dian)(dian)(dian)對電(dian)(dian)(dian)(dian)網的(de)沖鋒陷陣(zhen)。思忖到繞線旋子(zi)異(yi)(yi)步(bu)馬達(da)(da)有(you)機械(xie)換向(xiang)器(qi)(qi)跟(gen)電(dian)(dian)(dian)(dian)刷，存(cun)在故障率高的(de)缺(que)欠，因(yin)此咱們選(xuan)用YH型(xing)高轉差率三(san)相異(yi)(yi)步(bu)馬達(da)(da)來(lai)接(jie)替原來(lai)的(de)YZR型(xing)繞線旋子(zi)三(san)相異(yi)(yi)步(bu)馬達(da)(da)，同聲(sheng)選(xuan)用軟起(qi)(qi)動(dong)(dong)器(qi)(qi)來(lai)兌現主(zhu)電(dian)(dian)(dian)(dian)機的(de)限流起(qi)(qi)動(dong)(dong)。電(dian)(dian)(dian)(dian)控(kong)零碎的(de)論(lun)理控(kong)制采取三(san)菱公司的(de)FX2N型(xing)PLC實(shi)現。

軟啟(qi)動(dong)(dong)器在破(po)式剪板機中利用的(de)(de)(de)多余性。因為破(po)式剪板機主(zhu)拖(tuo)動(dong)(dong)電機功率為37kW，需采取(qu)起(qi)(qi)動(dong)(dong)限流(liu)(liu)辦(ban)法，以減小(xiao)(xiao)起(qi)(qi)動(dong)(dong)直流(liu)(liu)電對電網的(de)(de)(de)沖(chong)(chong)鋒(feng)陷陣。婦孺皆知，鼠(shu)籠異(yi)(yi)步(bu)(bu)馬達帶載(zai)間接起(qi)(qi)動(dong)(dong)時(shi)將會產生4～8倍額定直流(liu)(liu)電的(de)(de)(de)起(qi)(qi)動(dong)(dong)直流(liu)(liu)電，會對電網造成周折莫須(xu)有(you)。定量較(jiao)大的(de)(de)(de)電機，畸形不容(rong)許(xu)帶載(zai)間接起(qi)(qi)動(dong)(dong)，需采取(qu)起(qi)(qi)動(dong)(dong)限流(liu)(liu)辦(ban)法，以減小(xiao)(xiao)對電網的(de)(de)(de)沖(chong)(chong)鋒(feng)陷陣。避(bi)免鼠(shu)籠異(yi)(yi)步(bu)(bu)馬達間接起(qi)(qi)動(dong)(dong)時(shi)的(de)(de)(de)大直流(liu)(liu)電沖(chong)(chong)鋒(feng)陷陣，通常的(de)(de)(de)步(bu)(bu)驟是采取(qu)降壓起(qi)(qi)動(dong)(dong)。傳統的(de)(de)(de)鼠(shu)籠異(yi)(yi)步(bu)(bu)馬達降壓起(qi)(qi)動(dong)(dong)步(bu)(bu)驟有(you)：星(xing)—角起(qi)(qi)動(dong)(dong)、轉(zhuan)子串(chuan)電阻(zu)起(qi)(qi)動(dong)(dong)跟自(zi)耦變壓器起(qi)(qi)動(dong)(dong)。

德州剪板機廠家軟啟動器的選型及其外層線路設計。破式剪板機的起動內中屬于帶標準負載通例起動，因此軟起動器的選型可能間接從其出品選型畫冊中查出。主馬達參數為：Pn=37kW，In=72A。查ABB公司的軟起動器出品選型畫冊，滿意電壓頭銜400V、額定直流電≥72A這一技(ji)能前(qian)提(ti)的軟起動器型號為：PSS85/147-500L，其(qi)技(ji)能參數為：In=8。

隨著電腦(nao)技能跟風力電子(zi)技能在(zai)電氣控(kong)制畛(zhen)域的進一(yi)步停止，軟起動(dong)器的機(ji)能也(ye)始(shi)終遍布，機(ji)能日益強(qiang)大，它在(zai)輕產業(ye)當場大功率馬達軟啟動(dong)中的利用也(ye)日趨寬泛(fan)。白(bai)文說明了利用ABB軟啟動(dong)器，來兌現破式剪板機(ji)主(zhu)電機(ji)的軟啟動(dong)。通(tong)過一(yi)年多工夫的運(yun)行察(cha)看，整機(ji)電控(kong)零(ling)碎達成(cheng)了設計務求(qiu)，運(yun)行牢固(gu)，操作靈(ling)敏。
