西門子840D伺服電源炸機/模塊壞維修廠家，故(gu)(gu)障維修處理：采(cai)用(yong)加(jia)(jia)接(jie)電(dian)(dian)(dian)抗(kang)器(qi)(qi)(qi)的(de)(de)(de)(de)方(fang)式來(lai)抑(yi)(yi)制(zhi)高(gao)次諧波(bo)(bo)(bo)(bo)(bo)引(yin)起(qi)的(de)(de)(de)(de)電(dian)(dian)(dian)源(yuan)故(gu)(gu)障? (1)連接(jie)電(dian)(dian)(dian)路 所謂加(jia)(jia)接(jie)電(dian)(dian)(dian)抗(kang)器(qi)(qi)(qi),也就是在(zai)電(dian)(dian)(dian)源(yuan)輸入側與輸出(chu)側串(chuan)接(jie)適當的(de)(de)(de)(de)電(dian)(dian)(dian)抗(kang)器(qi)(qi)(qi),也可以(yi)設置 諧波(bo)(bo)(bo)(bo)(bo)濾波(bo)(bo)(bo)(bo)(bo)器(qi)(qi)(qi),但濾波(bo)(bo)(bo)(bo)(bo)器(qi)(qi)(qi)必須采(cai)用(yong)LC類型濾波(bo)(bo)(bo)(bo)(bo)方(fang)式的(de)(de)(de)(de)。 這(zhe)樣(yang)既增大(da)了電(dian)(dian)(dian)源(yuan)容量(liang)或負載阻抗(kang),又可以(yi)起(qi)到抑(yi)(yi)制(zhi)諧波(bo)(bo)(bo)(bo)(bo)的(de)(de)(de)(de)目的(de)(de)(de)(de)。 (2)具有(you)(you)進(jin)相電(dian)(dian)(dian)容器(qi)(qi)(qi)的(de)(de)(de)(de)系統(tong) 對于(yu)變(bian)頻(pin)器(qi)(qi)(qi)電(dian)(dian)(dian)源(yuan)具有(you)(you)進(jin)相電(dian)(dian)(dian)容器(qi)(qi)(qi)的(de)(de)(de)(de)系統(tong),由(you)于(yu)高(gao)次諧波(bo)(bo)(bo)(bo)(bo)電(dian)(dian)(dian)流會使電(dian)(dian)(dian)容器(qi)(qi)(qi)的(de)(de)(de)(de)電(dian)(dian)(dian)流增加(jia)(jia), 容易(yi)引(yin)起(qi)電(dian)(dian)(dian)容器(qi)(qi)(qi)嚴(yan)重發熱,故(gu)(gu)必須在(zai)電(dian)(dian)(dian)容器(qi)(qi)(qi)前串(chuan)接(jie)電(dian)(dian)(dian)抗(kang)器(qi)(qi)(qi),用(yong)于(yu)減小諧波(bo)(bo)(bo)(bo)(bo)分量(liang)。變(bian)頻(pin)器(qi)(qi)(qi)輸 入電(dian)(dian)(dian)源(yuan)端(duan)串(chuan)聯(lian)電(dian)(dian)(dian)抗(kang)器(qi)(qi)(qi)的(de)(de)(de)(de)方(fang)法。所加(jia)(jia)設的(de)(de)(de)(de)電(dian)(dian)(dian)抗(kang)器(qi)(qi)(qi)的(de)(de)(de)(de)電(dian)(dian)(dian)感量(liang)必須經(jing)過(guo)合理的(de)(de)(de)(de)計(ji)算(suan)，以(yi)防止產生IC振蕩。

加減(jian)速(su)模式選擇(ze)(ze)(ze)又叫加減(jian)速(su)曲(qu)線(xian)(xian)(xian)(xian)選擇(ze)(ze)(ze)，一般變(bian)(bian)頻器有線(xian)(xian)(xian)(xian)性、非(fei)(fei)(fei)線(xian)(xian)(xian)(xian)性和S三種曲(qu)線(xian)(xian)(xian)(xian)，通常大多選擇(ze)(ze)(ze)線(xian)(xian)(xian)(xian)性曲(qu)線(xian)(xian)(xian)(xian)；非(fei)(fei)(fei)線(xian)(xian)(xian)(xian)性曲(qu)線(xian)(xian)(xian)(xian)適(shi)用于變(bian)(bian)轉(zhuan)(zhuan)矩(ju)負載(zai)(zai)，如(ru)風機等；S曲(qu)線(xian)(xian)(xian)(xian)適(shi)用于恒轉(zhuan)(zhuan)矩(ju)負載(zai)(zai)，其加減(jian)速(su)變(bian)(bian)化較(jiao)為緩慢，設定時可根(gen)據負載(zai)(zai)轉(zhuan)(zhuan)矩(ju)特性，選擇(ze)(ze)(ze)相應曲(qu)線(xian)(xian)(xian)(xian)，但也有例外，筆(bi)者在調試一臺鍋爐引風機的變(bian)(bian)頻器時，先(xian)將(jiang)加減(jian)速(su)曲(qu)線(xian)(xian)(xian)(xian)選擇(ze)(ze)(ze)非(fei)(fei)(fei)線(xian)(xian)(xian)(xian)性曲(qu)線(xian)(xian)(xian)(xian)，一起動(dong)運轉(zhuan)(zhuan)變(bian)(bian)頻器就跳閘，調整改變(bian)(bian)許多參數(shu)無效果，后改為S曲(qu)線(xian)(xian)(xian)(xian)后就正常了
