使(shi)用(yong)(yong)(yong)三(san)菱(ling)(ling)變(bian)(bian)(bian)頻(pin)器(qi)(qi)有(you)什么好(hao)處？1、三(san)菱(ling)(ling)變(bian)(bian)(bian)頻(pin)器(qi)(qi)首先使(shi)用(yong)(yong)(yong)的(de)(de)是價格(ge)便宜、容易維護的(de)(de)籠型感應電(dian)動(dong)(dong)機(ji)。并且，可直接使(shi)用(yong)(yong)(yong)原有(you)感應電(dian)動(dong)(dong)機(ji)，不(bu)必(bi)改造機(ji)械和驅(qu)動(dong)(dong)系統(tong)，提高機(ji)械功能。2、可進(jin)行連續、普遍的(de)(de)操作。使(shi)用(yong)(yong)(yong)原有(you)的(de)(de)常用(yong)(yong)(yong)電(dian)源時(shi)，利用(yong)(yong)(yong)另外的(de)(de)變(bian)(bian)(bian)速(su)設備（減速(su)機(ji)、傳動(dong)(dong)帶等）進(jin)行變(bian)(bian)(bian)速(su)。但是，只能進(jin)行階段性變(bian)(bian)(bian)速(su)、不(bu)能進(jin)行連續變(bian)(bian)(bian)速(su)。3、以變(bian)(bian)(bian)頻(pin)器(qi)(qi)可替代DC發(fa)動(dong)(dong)機(ji)，這時(shi)使(shi)用(yong)(yong)(yong)感應電(dian)動(dong)(dong)機(ji)。與DC發(fa)動(dong)(dong)機(ji)相(xiang)同，無需(xu)刷子(zi)、slip-ring等，維護性和耐環境性優良。4、變(bian)(bian)(bian)頻(pin)器(qi)(qi)可以軟啟動(dong)(dong)和軟關閉，任意調整(zheng)發(fa)動(dong)(dong)機(ji)的(de)(de)加/減速(su)時(shi)間。變(bian)(bian)(bian)頻(pin)器(qi)(qi)的(de)(de)輸(shu)出側嚴禁(jin)安(an)裝(zhuang)接觸器(qi)(qi)、開關器(qi)(qi)件。浙江FR-F800變(bian)(bian)(bian)頻(pin)器(qi)(qi)廠家

三(san)(san)菱變(bian)(bian)(bian)(bian)頻(pin)器(qi)(qi)(qi)的(de)(de)安(an)(an)裝(zhuang)環(huan)境(jing)：1、三(san)(san)菱變(bian)(bian)(bian)(bian)頻(pin)器(qi)(qi)(qi)工作(zuo)溫度(du)：三(san)(san)菱變(bian)(bian)(bian)(bian)頻(pin)器(qi)(qi)(qi)內部(bu)是大(da)功率(lv)的(de)(de)電子元件(jian)，極易(yi)受(shou)到工作(zuo)溫度(du)的(de)(de)影響，產品(pin)一(yi)般要求為0～55℃，但為了保證工作(zuo)安(an)(an)全、可靠(kao)，使用(yong)時應考慮留(liu)有(you)余地，應該(gai)控制在(zai)40℃以(yi)下。在(zai)控制箱中(zhong)，三(san)(san)菱變(bian)(bian)(bian)(bian)頻(pin)器(qi)(qi)(qi)一(yi)般應安(an)(an)裝(zhuang)在(zai)箱體上部(bu)，并嚴格(ge)遵守(shou)產品(pin)說明書中(zhong)的(de)(de)安(an)(an)裝(zhuang)要求，不允許(xu)把發熱元件(jian)或易(yi)發熱的(de)(de)元件(jian)緊靠(kao)三(san)(san)菱變(bian)(bian)(bian)(bian)頻(pin)器(qi)(qi)(qi)的(de)(de)底部(bu)安(an)(an)裝(zhuang)。2、三(san)(san)菱變(bian)(bian)(bian)(bian)頻(pin)器(qi)(qi)(qi)環(huan)境(jing)溫度(du)：溫度(du)太高且溫度(du)變(bian)(bian)(bian)(bian)化較(jiao)(jiao)大(da)時，三(san)(san)菱變(bian)(bian)(bian)(bian)頻(pin)器(qi)(qi)(qi)內部(bu)易(yi)出現結(jie)露現象，其(qi)絕緣性能(neng)就會(hui)(hui)大(da)幅降低，甚至可能(neng)引發短路(lu)事(shi)故(gu)。必要時，必須(xu)在(zai)箱中(zhong)增加干燥劑和加熱器(qi)(qi)(qi)。在(zai)水處理間，一(yi)般水汽都比(bi)較(jiao)(jiao)重，如(ru)果溫度(du)變(bian)(bian)(bian)(bian)化大(da)的(de)(de)話(hua)，這(zhe)個問題會(hui)(hui)比(bi)較(jiao)(jiao)突出。浙江FR-F800變(bian)(bian)(bian)(bian)頻(pin)器(qi)(qi)(qi)廠家變(bian)(bian)(bian)(bian)頻(pin)器(qi)(qi)(qi)有(you)哪些功能(neng)特(te)點(dian)？

三(san)(san)(san)菱(ling)變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)的(de)工作原(yuan)理：1、主回(hui)路：電(dian)(dian)抗器(qi)(qi)(qi)的(de)作用是防(fang)止三(san)(san)(san)菱(ling)變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)產生(sheng)的(de)高(gao)次諧波通過電(dian)(dian)源的(de)輸(shu)(shu)入(ru)回(hui)路返回(hui)到電(dian)(dian)網從而影響其(qi)他的(de)受電(dian)(dian)設(she)備，需要根據三(san)(san)(san)菱(ling)變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)的(de)容量大小來(lai)決定是否需要加電(dian)(dian)抗器(qi)(qi)(qi)；濾波器(qi)(qi)(qi)是安裝在三(san)(san)(san)菱(ling)變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)的(de)輸(shu)(shu)出端(duan)，減少三(san)(san)(san)菱(ling)變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)輸(shu)(shu)出的(de)高(gao)次諧波，當三(san)(san)(san)菱(ling)變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)到電(dian)(dian)機的(de)距離較遠時(shi)(shi)，應該安裝濾波器(qi)(qi)(qi)。雖(sui)然(ran)三(san)(san)(san)菱(ling)變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)本(ben)(ben)身(shen)有各種(zhong)保護功能(neng)，但缺相保護卻并不完(wan)美，斷路器(qi)(qi)(qi)在主回(hui)路中起到過載，缺相等保護，選(xuan)(xuan)型時(shi)(shi)可按照三(san)(san)(san)菱(ling)變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)的(de)容量進行選(xuan)(xuan)擇。可以用三(san)(san)(san)菱(ling)變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)本(ben)(ben)身(shen)的(de)過載保護代替熱繼電(dian)(dian)器(qi)(qi)(qi)。2、控(kong)制回(hui)路：具(ju)有工頻(pin)(pin)變(bian)(bian)(bian)頻(pin)(pin)的(de)手動切換，以便在變(bian)(bian)(bian)頻(pin)(pin)出現故障時(shi)(shi)可以手動切工頻(pin)(pin)運行，因輸(shu)(shu)出端(duan)不能(neng)加電(dian)(dian)壓，固(gu)工頻(pin)(pin)和變(bian)(bian)(bian)頻(pin)(pin)要有互鎖(suo)。

變頻器(qi)(qi)(qi)的(de)作用(yong)：1、可(ke)(ke)逆(ni)運行(xing)(xing)控(kong)(kong)(kong)制(zhi)：在變頻器(qi)(qi)(qi)控(kong)(kong)(kong)制(zhi)中，要(yao)(yao)實現可(ke)(ke)逆(ni)運行(xing)(xing)控(kong)(kong)(kong)制(zhi)無(wu)須額外的(de)可(ke)(ke)逆(ni)控(kong)(kong)(kong)制(zhi)裝置，只需要(yao)(yao)改變輸出電(dian)(dian)壓的(de)相(xiang)序即可(ke)(ke)，這樣就(jiu)(jiu)能降(jiang)低(di)維護(hu)成(cheng)本(ben)和節(jie)(jie)省安裝空間(jian)。2、減少機(ji)(ji)械(xie)傳動部件(jian)：由于目前矢量控(kong)(kong)(kong)制(zhi)變頻器(qi)(qi)(qi)加上同步電(dian)(dian)機(ji)(ji)就(jiu)(jiu)能實現高效的(de)轉(zhuan)矩輸出，從(cong)(cong)而節(jie)(jie)省齒輪箱等機(ji)(ji)械(xie)傳動部件(jian)，構(gou)成(cheng)直接(jie)(jie)變頻傳動系統。從(cong)(cong)而就(jiu)(jiu)能降(jiang)低(di)成(cheng)本(ben)和空間(jian),提高穩定性。3、啟動時需要(yao)(yao)的(de)功率(lv)(lv)更(geng)低(di)：電(dian)(dian)機(ji)(ji)功率(lv)(lv)與(yu)電(dian)(dian)流和電(dian)(dian)壓的(de)乘積成(cheng)正(zheng)比，那(nei)么通過(guo)工頻直接(jie)(jie)啟動的(de)電(dian)(dian)機(ji)(ji)消耗的(de)功率(lv)(lv)將大幅高于變頻啟動所(suo)需要(yao)(yao)的(de)功率(lv)(lv)。如果采(cai)用(yong)變頻器(qi)(qi)(qi)進(jin)行(xing)(xing)電(dian)(dian)機(ji)(ji)起(qi)停,就(jiu)(jiu)不會產(chan)生類似(si)的(de)問題。變頻器(qi)(qi)(qi)本(ben)身(shen)具(ju)有各種保(bao)護(hu)功能，如：負載(zai)側接(jie)(jie)地保(bao)護(hu)、短路保(bao)護(hu)、電(dian)(dian)流限制(zhi)、逆(ni)變器(qi)(qi)(qi)過(guo)熱、過(guo)載(zai)等。

在維護變頻(pin)(pin)器(qi)的(de)(de)(de)過程中(zhong)我(wo)們需要注意哪些地方？1、檢查(cha)動力電(dian)(dian)纜(lan)(lan)、控(kong)(kong)制電(dian)(dian)纜(lan)(lan)和其他電(dian)(dian)纜(lan)(lan)是(shi)否損(sun)壞(huai)，電(dian)(dian)線(xian)的(de)(de)(de)防護罩和絕緣層是(shi)否完好(hao)。2、檢查(cha)變頻(pin)(pin)器(qi)是(shi)否受(shou)潮(chao)和露(lu)珠。如果是(shi)，請先干(gan)燥(zao)(zao)(通(tong)風、加熱、添(tian)加干(gan)燥(zao)(zao)劑等)。)3、檢查(cha)變頻(pin)(pin)器(qi)后負載的(de)(de)(de)機械(xie)部(bu)分是(shi)否有(you)明顯損(sun)壞(huai)(滑動不順暢、堵塞等。)4、請有(you)秩序地打開(kai)電(dian)(dian)源(yuan)。先關(guan)(guan)總開(kai)關(guan)(guan)，再(zai)關(guan)(guan)斷(duan)路開(kai)關(guan)(guan)，之(zhi)后再(zai)依次打開(kai)各(ge)種機器(qi)。5、請不要在排除上(shang)述問題(ti)后立即運(yun)行設備(bei)電(dian)(dian)源(yuan)。通(tong)電(dian)(dian)20分鐘以干(gan)燥(zao)(zao)設備(bei)內部(bu)的(de)(de)(de)組(zu)件。6、觀察無問題(ti)后，低速(su)(su)試運(yun)轉(zhuan)一段時(shi)間，正常運(yun)轉(zhuan)前預演，無異常時(shi)再(zai)全速(su)(su)運(yun)轉(zhuan)。三菱變頻(pin)(pin)器(qi)是(shi)利用(yong)電(dian)(dian)力半導體器(qi)件的(de)(de)(de)通(tong)斷(duan)作用(yong)將(jiang)工頻(pin)(pin)電(dian)(dian)源(yuan)變換為另一頻(pin)(pin)率(lv)的(de)(de)(de)電(dian)(dian)能控(kong)(kong)制裝置(zhi)。浙江FR-F800變頻(pin)(pin)器(qi)廠(chang)家

變頻器(qi)的(de)作用是改變交流(liu)電機供電的(de)頻率和(he)幅(fu)值，因(yin)而改變其運(yun)動(dong)磁場的(de)周(zhou)期，達到平(ping)滑控制電動(dong)機轉(zhuan)速(su)的(de)目的(de)。浙江FR-F800變頻器(qi)廠家

變(bian)(bian)頻器(qi)有哪(na)些功(gong)能特(te)點？1、軟啟(qi)動(dong)功(gong)能：用(yong)市電(dian)(dian)(dian)直接啟(qi)動(dong)電(dian)(dian)(dian)機(ji)(ji)，其啟(qi)動(dong)電(dian)(dian)(dian)電(dian)(dian)(dian)流為(wei)(wei)電(dian)(dian)(dian)機(ji)(ji)額定電(dian)(dian)(dian)流的5-7倍。這種電(dian)(dian)(dian)機(ji)(ji)直啟(qi)情況(kuang)下(xia)，會導(dao)致電(dian)(dian)(dian)網電(dian)(dian)(dian)壓(ya)下(xia)降，影響其他用(yong)電(dian)(dian)(dian)設(she)備的正常運行。采用(yong)變(bian)(bian)頻器(qi)軟啟(qi)動(dong)，其啟(qi)動(dong)電(dian)(dian)(dian)流一(yi)般(ban)(ban)為(wei)(wei)額定電(dian)(dian)(dian)流的1.2-1.5倍，有效地降低了啟(qi)動(dong)沖擊電(dian)(dian)(dian)流，減少變(bian)(bian)壓(ya)器(qi)的占有量，2、變(bian)(bian)頻調(diao)速(su)(su)(su)(su)：傳(chuan)統的電(dian)(dian)(dian)機(ji)(ji)調(diao)速(su)(su)(su)(su)為(wei)(wei)變(bian)(bian)極(ji)調(diao)速(su)(su)(su)(su)；根據三(san)相異步(bu)電(dian)(dian)(dian)動(dong)機(ji)(ji)同轉速(su)(su)(su)(su)：可通過(guo)改(gai)(gai)變(bian)(bian)電(dian)(dian)(dian)機(ji)(ji)定子(zi)繞(rao)組的磁極(ji)對數,就能改(gai)(gai)變(bian)(bian)它的同步(bu)轉速(su)(su)(su)(su),從而改(gai)(gai)變(bian)(bian)轉子(zi)轉速(su)(su)(su)(su)。通過(guo)繞(rao)組的不同組合連接方式,一(yi)般(ban)(ban)可得到兩極(ji)、三(san)極(ji)、四極(ji)速(su)(su)(su)(su)度。調(diao)速(su)(su)(su)(su)范圍較窄，一(yi)般(ban)(ban)為(wei)(wei)雙速(su)(su)(su)(su)。浙江FR-F800變(bian)(bian)頻器(qi)廠家
