水阻柜,別稱水阻(zu),又(you)被(bei)稱作液阻(zu)柜,在中國各大廠礦企業很多普及(ji)化(hua)應用。

  水阻(zu)(zu),說白了(le),即水電(dian)(dian)(dian)(dian)阻(zu)(zu)器(qi)(又被(bei)稱作液(ye)阻(zu)(zu)柜)。此技術性(xing)開始(shi)起源于日本國,在(zai)1985年上半年度被(bei)引(yin)入到我(wo)國,在(zai)現如今大空間電(dian)(dian)(dian)(dian)動(dong)機(ji)上獲(huo)得普遍的(de)(de)運用,目(mu)前比較合(he)適我(wo)國國情。因為電(dian)(dian)(dian)(dian)機(ji)立即啟(qi)動(dong)時,啟(qi)動(dong)電(dian)(dian)(dian)(dian)流量會(hui)超過(guo)電(dian)(dian)(dian)(dian)動(dong)機(ji)額定(ding)電(dian)(dian)(dian)(dian)壓(ya)的(de)(de)7~8倍,通常上一級變電(dian)(dian)(dian)(dian)器(qi)的(de)(de)容積都承擔不(bu)上,非常是(shi)功率的(de)(de)電(dian)(dian)(dian)(dian)動(dong)機(ji),務(wu)必改裝啟(qi)動(dong)機(ji)器(qi)設備,不(bu)然會(hui)導致變電(dian)(dian)(dian)(dian)器(qi)部分下跳電(dian)(dian)(dian)(dian)。

  以(yi)前的啟動(dong)(dong)機器(qi)設備,關鍵(jian)有(you):變(bian)(bian)阻器(qi)啟動(dong)(dong)和(he)頻(pin)敏啟動(dong)(dong)等(deng)。變(bian)(bian)阻器(qi)啟動(dong)(dong)根據轉換電(dian)(dian)阻器(qi)的總數,更(geng)改串(chuan)入電(dian)(dian)動(dong)(dong)機的電(dian)(dian)阻器(qi),因為轉換電(dian)(dian)阻器(qi)歸屬于有(you)級變(bian)(bian)速,因此轉換一瞬間沖擊(ji)性很大(da)。頻(pin)敏啟動(dong)(dong)聽說是脈沖電(dian)(dian)流成份(fen)較為大(da)。

隨之技術性(xing)(xing)的逐漸(jian)發(fa)展(zhan),中后期發(fa)展(zhan)趨勢的水阻啟動(dong),因(yin)為(wei)歸屬于無極調整,因(yin)此啟動(dong)全過程較光滑,轉(zhuan)換(huan)無沖擊性(xing)(xing)電流量這(zhe)些(xie)優勢。

水阻柜原理

  在(zai)被控纏線電(dian)(dian)機(ji)的(de)電(dian)(dian)機(ji)轉子(zi)控制(zhi)(zhi)回(hui)路(lu)中(zhong)串(chuan)(chuan)入(ru)(ru)獨特(te)配(pei)備的(de)鋰(li)電(dian)(dian)池(chi)電(dian)(dian)解液(ye)做為電(dian)(dian)阻(zu)器(qi),并(bing)根據調節(jie)鋰(li)電(dian)(dian)池(chi)電(dian)(dian)解液(ye)的(de)濃度值(zhi)及更改兩方面板間的(de)間距使串(chuan)(chuan)入(ru)(ru)電(dian)(dian)阻(zu)器(qi)電(dian)(dian)阻(zu)在(zai)啟(qi)動全過(guo)程中(zhong)自始至終考慮電(dian)(dian)動機(ji)機(ji)械設備特(te)點對串(chuan)(chuan)入(ru)(ru)阻(zu)值(zhi)的(de)規(gui)定,進而使電(dian)(dian)機(ji)在(zai)得到(dao)較大起動轉矩(ju)及少(shao)啟(qi)動電(dian)(dian)流(liu)量的(de)狀況(kuang)下勻(yun)稱升速,啟(qi)動完(wan)畢,電(dian)(dian)器(qi)開(kai)關短接(jie)電(dian)(dian)機(ji)轉子(zi)控制(zhi)(zhi)回(hui)路(lu)。

水阻柜的分類依照電動機的不一樣,分成(cheng)二(er)種水(shui)阻:

  這(zhe)(zhe)種是轉(zhuan)子(zi)串(chuan)水(shui)阻,即(ji)電(dian)動(dong)機歸屬于繞線式電(dian)機,即(ji)電(dian)機轉(zhuan)子(zi)控(kong)制(zhi)回路(lu)未短接。這(zhe)(zhe)時(shi)根(gen)據更(geng)改(gai)啟動(dong)全(quan)過程中電(dian)機轉(zhuan)子(zi)控(kong)制(zhi)回路(lu)的阻值(zhi)來逐步實(shi)現軟起(qi)動(dong)。

二是定(ding)子串水阻,即電(dian)(dian)動機(ji)歸屬于鼠籠型電(dian)(dian)動機(ji),即電(dian)(dian)機(ji)轉(zhuan)子控(kong)制回(hui)路在(zai)電(dian)(dian)動機(ji)內部已短接。這時根(gen)據(ju)更(geng)改啟動全過程中電(dian)(dian)機(ji)定(ding)子控(kong)制回(hui)路的阻值來逐步實現軟起動。

依照(zhao)保持方法(fa)的不一樣,分(fen)(fen)成二種水(shui)(shui)阻:這種是(shi)溫度(du)更(geng)改(gai)(gai)(gai)電(dian)(dian)(dian)阻尺寸,即在起(qi)動全過(guo)程中,因為液(ye)體內部的鋰電(dian)(dian)(dian)池電(dian)(dian)(dian)解(jie)液(ye)隨之液(ye)體溫度(du)的上升(sheng)(sheng),鋰電(dian)(dian)(dian)池電(dian)(dian)(dian)解(jie)液(ye)分(fen)(fen)子(zi)結構主題活動加(jia)重(zhong),使阻值逐漸減少,逐漸更(geng)改(gai)(gai)(gai)機(ji)端電(dian)(dian)(dian)壓(ya),使之超過(guo)軟起(qi)動的目地(di)(di)。二是(shi)根據柜里(li)提(ti)升(sheng)(sheng)極片(pian)升(sheng)(sheng)降機(ji)電(dian)(dian)(dian)動機(ji),均(jun)速(su)的更(geng)改(gai)(gai)(gai)I/O極片(pian)中間的間距,更(geng)改(gai)(gai)(gai)阻值的尺寸,逐漸更(geng)改(gai)(gai)(gai)機(ji)端電(dian)(dian)(dian)壓(ya),使之超過(guo)軟起(qi)動的目地(di)(di)。在其中倘若溫度(du)更(geng)改(gai)(gai)(gai)電(dian)(dian)(dian)阻尺寸,關鍵歸(gui)屬(shu)于定子(zi)串水(shui)(shui)阻系列產品。若根據極片(pian)升(sheng)(sheng)降機(ji)電(dian)(dian)(dian)動機(ji)更(geng)改(gai)(gai)(gai)電(dian)(dian)(dian)阻尺寸,則定子(zi)和轉子(zi)串水(shui)(shui)阻都(dou)可以。
