三菱(ling)變(bian)頻(pin)(pin)器(qi)(qi)(qi)電(dian)(dian)(dian)磁干擾問題(ti)：1、三菱(ling)變(bian)頻(pin)(pin)器(qi)(qi)(qi)在(zai)工作中(zhong)(zhong)由于(yu)整流(liu)和變(bian)頻(pin)(pin)會(hui)產(chan)生高次諧波，這種高次諧波會(hui)通過供電(dian)(dian)(dian)回路進入整個供電(dian)(dian)(dian)網(wang)絡，從而影響其他儀表。如(ru)果(guo)三菱(ling)變(bian)頻(pin)(pin)器(qi)(qi)(qi)的(de)功率很大占整個系(xi)統25以上(shang)(shang)，需(xu)要(yao)(yao)考慮控(kong)制電(dian)(dian)(dian)源(yuan)的(de)抗干擾措施。2、當系(xi)統中(zhong)(zhong)有(you)高頻(pin)(pin)沖擊負(fu)載(zai)如(ru)電(dian)(dian)(dian)焊機、電(dian)(dian)(dian)鍍電(dian)(dian)(dian)源(yuan)時，變(bian)頻(pin)(pin)器(qi)(qi)(qi)本身會(hui)因(yin)為干擾而出現(xian)保護(hu)，則考慮整個系(xi)統的(de)電(dian)(dian)(dian)源(yuan)質量問題(ti)。三菱(ling)變(bian)頻(pin)(pin)器(qi)(qi)(qi)防(fang)(fang)護(hu)問題(ti)需(xu)要(yao)(yao)注意以下幾點(dian)：1、防(fang)(fang)水(shui)防(fang)(fang)的(de)結(jie)(jie)露：如(ru)果(guo)變(bian)頻(pin)(pin)器(qi)(qi)(qi)放在(zai)現(xian)場，需(xu)要(yao)(yao)注意變(bian)頻(pin)(pin)器(qi)(qi)(qi)柜上(shang)(shang)方不(bu)的(de)有(you)管道法蘭或(huo)其他漏點(dian)，在(zai)變(bian)頻(pin)(pin)器(qi)(qi)(qi)附近不(bu)能有(you)噴(pen)濺(jian)水(shui)流(liu)，總之現(xian)場柜體防(fang)(fang)護(hu)等(deng)級要(yao)(yao)在(zai)IP43以上(shang)(shang)。2、三菱(ling)變(bian)頻(pin)(pin)器(qi)(qi)(qi)的(de)防(fang)(fang)塵(chen)：所有(you)進風口要(yao)(yao)設置(zhi)防(fang)(fang)塵(chen)網(wang)阻隔絮狀雜(za)物進入，防(fang)(fang)塵(chen)網(wang)應該設計為可拆卸式，以方便(bian)清理(li)(li)，維(wei)護(hu)。防(fang)(fang)塵(chen)網(wang)的(de)網(wang)格(ge)根據(ju)現(xian)場的(de)具體情況確定，防(fang)(fang)塵(chen)網(wang)四周(zhou)與控(kong)制柜的(de)結(jie)(jie)合處要(yao)(yao)處理(li)(li)嚴密。成都FR-F800變(bian)頻(pin)(pin)器(qi)(qi)(qi)銷售變(bian)頻(pin)(pin)器(qi)(qi)(qi)的(de)作用(yong)是什(shen)么(me)？

變(bian)(bian)(bian)頻器工作(zuo)原理：1、整(zheng)流(liu)(liu)(liu)器：它(ta)(ta)的(de)(de)作(zuo)用是把三相(xiang)(或單(dan)相(xiang))交(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)源(yuan)整(zheng)流(liu)(liu)(liu)成(cheng)(cheng)直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)源(yuan)。在SPWM變(bian)(bian)(bian)頻器中(zhong)，大(da)(da)多采用全波整(zheng)流(liu)(liu)(liu)電(dian)(dian)(dian)路(lu)(lu)(lu)。大(da)(da)多數中(zhong)、小容量(liang)的(de)(de)變(bian)(bian)(bian)頻器中(zhong)，整(zheng)流(liu)(liu)(liu)器件(jian)采用不可控(kong)(kong)的(de)(de)整(zheng)流(liu)(liu)(liu)二極(ji)管或者二極(ji)管模(mo)塊。2、逆(ni)(ni)變(bian)(bian)(bian)器：它(ta)(ta)的(de)(de)作(zuo)用與整(zheng)流(liu)(liu)(liu)器相(xiang)反，是將直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)逆(ni)(ni)變(bian)(bian)(bian)為電(dian)(dian)(dian)壓和頻率可變(bian)(bian)(bian)的(de)(de)交(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)，以實現交(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)機變(bian)(bian)(bian)頻調速(su)。逆(ni)(ni)變(bian)(bian)(bian)電(dian)(dian)(dian)路(lu)(lu)(lu)由開(kai)關器件(jian)構成(cheng)(cheng)，大(da)(da)多采用橋式電(dian)(dian)(dian)路(lu)(lu)(lu)，常稱逆(ni)(ni)變(bian)(bian)(bian)橋。在SPWM變(bian)(bian)(bian)頻器中(zhong)，開(kai)關器件(jian)接受控(kong)(kong)制電(dian)(dian)(dian)路(lu)(lu)(lu)中(zhong)SPWM調制信號的(de)(de)控(kong)(kong)制，將直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)逆(ni)(ni)變(bian)(bian)(bian)成(cheng)(cheng)三相(xiang)交(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)。3、控(kong)(kong)制電(dian)(dian)(dian)路(lu)(lu)(lu)：這部分電(dian)(dian)(dian)路(lu)(lu)(lu)由運(yun)算電(dian)(dian)(dian)路(lu)(lu)(lu)、檢(jian)測電(dian)(dian)(dian)路(lu)(lu)(lu)、驅(qu)動電(dian)(dian)(dian)路(lu)(lu)(lu)、保(bao)護電(dian)(dian)(dian)路(lu)(lu)(lu)等(deng)組成(cheng)(cheng)，一般均采用大(da)(da)規模(mo)集成(cheng)(cheng)電(dian)(dian)(dian)路(lu)(lu)(lu)。

變(bian)(bian)頻器(qi)的(de)(de)(de)(de)(de)作用是什么(me)？1、在自(zi)動(dong)(dong)(dong)化系(xi)統(tong)(tong)中(zhong)的(de)(de)(de)(de)(de)應用：由于變(bian)(bian)頻器(qi)內(nei)置(zhi)有(you)32位或(huo)者16位的(de)(de)(de)(de)(de)微處理器(qi)，具有(you)多種(zhong)算(suan)數邏(luo)輯運算(suan)功(gong)(gong)能(neng)和(he)(he)智能(neng)控制(zhi)(zhi)(zhi)功(gong)(gong)能(neng)，輸(shu)出頻率精度為0.1%~60%，且(qie)設置(zhi)有(you)完善的(de)(de)(de)(de)(de)檢測(ce)、保護環節(jie)，因(yin)(yin)此在自(zi)動(dong)(dong)(dong)化系(xi)統(tong)(tong)中(zhong)得到(dao)普(pu)遍應用。例如，化纖工業(ye)中(zhong)的(de)(de)(de)(de)(de)卷(juan)繞、拉(la)伸、計(ji)量(liang)、導(dao)絲；玻(bo)璃工業(ye)中(zhong)的(de)(de)(de)(de)(de)平板玻(bo)璃退(tui)火爐、玻(bo)璃窯攪拌、拉(la)邊機(ji)、制(zhi)(zhi)(zhi)瓶機(ji)；電(dian)(dian)弧(hu)爐自(zi)動(dong)(dong)(dong)加(jia)料、配(pei)料系(xi)統(tong)(tong)以及電(dian)(dian)梯的(de)(de)(de)(de)(de)智能(neng)控制(zhi)(zhi)(zhi)等(deng)。2、變(bian)(bian)頻器(qi)還可以普(pu)遍用于傳送、起(qi)重(zhong)、擠壓和(he)(he)機(ji)床等(deng)各種(zhong)機(ji)械設備(bei)控制(zhi)(zhi)(zhi)領域(yu)，它(ta)可以提高(gao)工藝(yi)(yi)水平和(he)(he)產品質量(liang)，減(jian)少設備(bei)的(de)(de)(de)(de)(de)沖擊和(he)(he)噪(zao)音，延(yan)長(chang)設備(bei)的(de)(de)(de)(de)(de)使(shi)用壽命。采用變(bian)(bian)頻調速(su)控制(zhi)(zhi)(zhi)后，使(shi)機(ji)械系(xi)統(tong)(tong)簡化，操(cao)作和(he)(he)控制(zhi)(zhi)(zhi)更加(jia)方便，有(you)的(de)(de)(de)(de)(de)甚至改(gai)(gai)變(bian)(bian)原有(you)的(de)(de)(de)(de)(de)工藝(yi)(yi)規范，從而提高(gao)整個設備(bei)的(de)(de)(de)(de)(de)功(gong)(gong)能(neng)。變(bian)(bian)頻器(qi)的(de)(de)(de)(de)(de)作用是改(gai)(gai)變(bian)(bian)交流電(dian)(dian)機(ji)供電(dian)(dian)的(de)(de)(de)(de)(de)頻率和(he)(he)幅值(zhi)，因(yin)(yin)而改(gai)(gai)變(bian)(bian)其(qi)運動(dong)(dong)(dong)磁場的(de)(de)(de)(de)(de)周期，達到(dao)平滑控制(zhi)(zhi)(zhi)電(dian)(dian)動(dong)(dong)(dong)機(ji)轉速(su)的(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)。

三菱變(bian)(bian)頻器(qi)的(de)使用(yong)注意事(shi)件(jian)：1、接(jie)(jie)(jie)地(di)(di)：變(bian)(bian)頻器(qi)正確接(jie)(jie)(jie)地(di)(di)是(shi)(shi)提高控(kong)制系(xi)統(tong)靈(ling)敏度、抑制噪聲能(neng)(neng)力(li)的(de)重(zhong)(zhong)要手段(duan)，變(bian)(bian)頻器(qi)接(jie)(jie)(jie)地(di)(di)端(duan)子E(G)接(jie)(jie)(jie)地(di)(di)電(dian)(dian)(dian)阻(zu)越(yue)小(xiao)越(yue)好(hao)，接(jie)(jie)(jie)地(di)(di)導線截(jie)面積應(ying)(ying)不小(xiao)于(yu)2mm2，長度應(ying)(ying)控(kong)制在20m以(yi)內。變(bian)(bian)頻器(qi)的(de)接(jie)(jie)(jie)地(di)(di)必須與(yu)動力(li)設(she)備接(jie)(jie)(jie)地(di)(di)點分開，不能(neng)(neng)共(gong)地(di)(di)。信號(hao)(hao)輸入(ru)(ru)(ru)線的(de)屏蔽(bi)層，應(ying)(ying)接(jie)(jie)(jie)至(zhi)E(G)上，其另(ling)一端(duan)絕不能(neng)(neng)接(jie)(jie)(jie)于(yu)地(di)(di)端(duan)，否則(ze)會引起信號(hao)(hao)變(bian)(bian)化波(bo)動，使系(xi)統(tong)振蕩不止(zhi)。變(bian)(bian)頻器(qi)與(yu)控(kong)制柜之間(jian)應(ying)(ying)電(dian)(dian)(dian)氣連通，如果實際安裝(zhuang)有困難(nan)，可利用(yong)銅芯導線跨接(jie)(jie)(jie)。2、防(fang)雷：在變(bian)(bian)頻器(qi)中，一般都設(she)有雷電(dian)(dian)(dian)吸收網(wang)絡，主要防(fang)止(zhi)瞬(shun)間(jian)的(de)雷電(dian)(dian)(dian)侵入(ru)(ru)(ru)，使變(bian)(bian)頻器(qi)損(sun)壞。但在實際工作(zuo)中，特別是(shi)(shi)電(dian)(dian)(dian)源(yuan)線架空引入(ru)(ru)(ru)的(de)情況下，單靠變(bian)(bian)頻器(qi)的(de)吸收網(wang)絡是(shi)(shi)不能(neng)(neng)滿足要求的(de)。在雷電(dian)(dian)(dian)活躍地(di)(di)區，這一問(wen)題尤為重(zhong)(zhong)要，如果電(dian)(dian)(dian)源(yuan)是(shi)(shi)架空進線，在進線處裝(zhuang)設(she)變(bian)(bian)頻避雷器(qi)(選件(jian))，或有按(an)規范要求在離變(bian)(bian)頻器(qi)20m的(de)遠處預埋鋼管做接(jie)(jie)(jie)地(di)(di)保護(hu)。如果電(dian)(dian)(dian)源(yuan)是(shi)(shi)電(dian)(dian)(dian)纜引入(ru)(ru)(ru)，則(ze)應(ying)(ying)做好(hao)控(kong)制室的(de)防(fang)雷系(xi)統(tong)，以(yi)防(fang)雷電(dian)(dian)(dian)竄入(ru)(ru)(ru)破壞設(she)備。變(bian)(bian)頻器(qi)的(de)出現(xian)，使得復雜的(de)調速控(kong)制簡單化。成都FR-F800變(bian)(bian)頻器(qi)銷售
