西門子PCU50風扇不轉/顯示器不亮維修，檢(jian)查方法 對(dui)這種(zhong)故障(zhang),應先(xian)檢(jian)查840D系統本(ben)身是否異(yi)(yi)常(chang)、參數設置是否正(zheng)確、調速輸(shu)入(ru)(ru)(ru)信(xin)號是否 正(zheng)常(chang)。如均正(zheng)常(chang),且運行(xing)時(shi)測(ce)得變(bian)頻(pin)(pin)器(qi)(qi)直(zhi)流(liu)母(mu)線(xian)(xian)(xian)電(dian)(dian)(dian)壓(ya)(ya)只有約450V(正(zheng)常(chang)值(zhi)應為(wei)(wei)580~600V), 則這種(zhong)故障(zhang)多(duo)是缺(que)相(缺(que)一相)引起的(de),應檢(jian)查電(dian)(dian)(dian)路中(zhong)的(de)空氣開(kai)關(guan)接觸是否良好。 (2)故障(zhang)原(yuan)因 變(bian)頻(pin)(pin)器(qi)(qi)輸(shu)入(ru)(ru)(ru)缺(que)相不報警仍(reng)能在低頻(pin)(pin)段工作(zuo)(zuo),是因為(wei)(wei)多(duo)數變(bian)頻(pin)(pin)器(qi)(qi)的(de)母(mu)線(xian)(xian)(xian)電(dian)(dian)(dian)壓(ya)(ya)下限為(wei)(wei)400V, 而當母(mu)線(xian)(xian)(xian)電(dian)(dian)(dian)壓(ya)(ya)降至400V以(yi)下時(shi),變(bian)頻(pin)(pin)器(qi)(qi)才(cai)顯示直(zhi)流(liu)母(mu)線(xian)(xian)(xian)電(dian)(dian)(dian)壓(ya)(ya)低故障(zhang)。當兩相輸(shu)入(ru)(ru)(ru)時(shi),直(zhi) 流(liu)線(xian)(xian)(xian)電(dian)(dian)(dian)壓(ya)(ya)為(wei)(wei) 大(da)于(yu)400V。當變(bian)頻(pin)(pin)器(qi)(qi)不運行(xing)時(shi),由(you)于(yu)濾波(bo)電(dian)(dian)(dian)容器(qi)(qi)的(de)作(zuo)(zuo)用,直(zhi)流(liu)電(dian)(dian)(dian)壓(ya)(ya)也(ye)可(ke)達(da)到正(zheng)常(chang)值(zhi)。新 型的(de)變(bian)頻(pin)(pin)器(qi)(qi)都采用PWM(脈寬調制)控(kong)制技術,調壓(ya)(ya)調頻(pin)(pin)的(de)工作(zuo)(zuo)在逆變(bian)橋完成(cheng),所以(yi)在 低頻(pin)(pin)段輸(shu)入(ru)(ru)(ru)缺(que)相仍(reng)可(ke)以(yi)正(zheng)常(chang)工作(zuo)(zuo),但因輸(shu)入(ru)(ru)(ru)電(dian)(dian)(dian)壓(ya)(ya)、輸(shu)出電(dian)(dian)(dian)壓(ya)(ya)低,造成(cheng)異(yi)(yi)步電(dian)(dian)(dian)動機轉(zhuan)矩低 頻(pin)(pin)率(lv)上不去。
