 工作(zuo)(zuo)原理。PowerSmartTM系列高(gao)壓(ya)(ya)(ya)(ya)變(bian)頻(pin)器(qi)(qi)是(shi)采用(yong)(yong)單(dan)元串聯(lian)多(duo)重化(hua)(hua)技(ji)術屬于電壓(ya)(ya)(ya)(ya)源(yuan)型(xing)高(gao)-高(gao)式高(gao)壓(ya)(ya)(ya)(ya)變(bian)頻(pin)器(qi)(qi)。所謂多(duo)重化(hua)(hua)，就(jiu)是(shi)每(mei)相(xiang)由(you)幾個低壓(ya)(ya)(ya)(ya)功率單(dan)元串聯(lian)組成，各功率單(dan)元由(you)一個多(duo)繞(rao)組的(de)(de)(de)(de)移相(xiang)隔離變(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)來獨(du)立(li)供電。采用(yong)(yong)多(duo)重化(hua)(hua)疊加(jia)的(de)(de)(de)(de)方式，使變(bian)頻(pin)器(qi)(qi)輸(shu)出電壓(ya)(ya)(ya)(ya)的(de)(de)(de)(de)諧(xie)(xie)波(bo)(bo)含量(liang)很小，不會引起(qi)(qi)電動機(ji)的(de)(de)(de)(de)附加(jia)諧(xie)(xie)波(bo)(bo)發(fa)(fa)熱。其輸(shu)出電壓(ya)(ya)(ya)(ya)的(de)(de)(de)(de)dV/dt也很小，不會給電機(ji)增加(jia)明顯的(de)(de)(de)(de)應力，因(yin)(yin)(yin)此(ci)可以向普(pu)通標準(zhun)型(xing)交流電動機(ji)供電，而(er)且無(wu)需降容使用(yong)(yong)。由(you)于輸(shu)出電壓(ya)(ya)(ya)(ya)的(de)(de)(de)(de)諧(xie)(xie)波(bo)(bo)和(he)dV/dt都很小，不需要附加(jia)輸(shu)出濾(lv)(lv)波(bo)(bo)器(qi)(qi)，輸(shu)出電纜也長度無(wu)要求(qiu)。由(you)于諧(xie)(xie)波(bo)(bo)很小，附加(jia)的(de)(de)(de)(de)轉矩(ju)脈動也很小，避(bi)免了由(you)此(ci)引起(qi)(qi)的(de)(de)(de)(de)機(ji)械共振。變(bian)頻(pin)器(qi)(qi)工作(zuo)(zuo)時的(de)(de)(de)(de)功率因(yin)(yin)(yin)數達(da)0.96以上，*了供電系統的(de)(de)(de)(de)要求(qiu)。因(yin)(yin)(yin)此(ci)不需要附加(jia)電源(yuan)濾(lv)(lv)波(bo)(bo)器(qi)(qi)或(huo)功率因(yin)(yin)(yin)數補償裝置，也不會與現(xian)有的(de)(de)(de)(de)補償電容裝置發(fa)(fa)生諧(xie)(xie)振，變(bian)頻(pin)器(qi)(qi)工作(zuo)(zuo)時不會對同一電網(wang)上運行的(de)(de)(de)(de)電氣設備發(fa)(fa)生干(gan)擾，因(yin)(yin)(yin)而(er)被人們(men)譽為(wei)“完(wan)美無(wu)諧(xie)(xie)波(bo)(bo)的(de)(de)(de)(de)高(gao)壓(ya)(ya)(ya)(ya)變(bian)頻(pin)器(qi)(qi)”。
西門子直流調速器6RA7087報警F040當天修好本(ben)文中(zhong)所(suo)指(zhi)的(de)(de)電(dian)(dian)(dian)機(ji)為感(gan)應式(shi)交(jiao)流電(dian)(dian)(dian)機(ji)，在(zai)工業領域(yu)所(suo)使用(yong)的(de)(de)大(da)部分電(dian)(dian)(dian)機(ji)均為此類型電(dian)(dian)(dian)機(ji)。感(gan)應式(shi)交(jiao)流電(dian)(dian)(dian)機(ji)（以下簡(jian)稱為電(dian)(dian)(dian)機(ji)）的(de)(de)旋轉速度(du)(du)近似取決于(yu)電(dian)(dian)(dian)機(ji)的(de)(de)極(ji)數和(he)頻率(lv)。由(you)電(dian)(dian)(dian)機(ji)的(de)(de)工作原理決定電(dian)(dian)(dian)機(ji)的(de)(de)極(ji)數是固定不(bu)變的(de)(de)。由(you)于(yu)該極(ji)數值(zhi)不(bu)是一個連續(xu)的(de)(de)數值(zhi)（為2的(de)(de)倍數，例如極(ji)數為2、4、6），所(suo)以不(bu)適(shi)合改(gai)變該值(zhi)來調(diao)整電(dian)(dian)(dian)機(ji)的(de)(de)速度(du)(du)。另外(wai)，頻率(lv)是電(dian)(dian)(dian)機(ji)供電(dian)(dian)(dian)電(dian)(dian)(dian)源的(de)(de)電(dian)(dian)(dian)信號，所(suo)以該值(zhi)能夠在(zai)電(dian)(dian)(dian)機(ji)的(de)(de)外(wai)面調(diao)節后再供給電(dian)(dian)(dian)機(ji)，這樣(yang)電(dian)(dian)(dian)機(ji)的(de)(de)旋轉速度(du)(du)就可自由(you)控制。
