西門子840D伺服電源炸機/模塊壞維修廠家，故障(zhang)維修(xiu)處(chu)理：采用(yong)(yong)加接(jie)電(dian)(dian)(dian)(dian)抗器(qi)(qi)(qi)(qi)的(de)(de)(de)方式來(lai)抑(yi)制高次(ci)(ci)諧(xie)波(bo)(bo)(bo)(bo)(bo)引起的(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)故障(zhang)? (1)連接(jie)電(dian)(dian)(dian)(dian)路(lu) 所謂加接(jie)電(dian)(dian)(dian)(dian)抗器(qi)(qi)(qi)(qi),也就是在電(dian)(dian)(dian)(dian)源(yuan)(yuan)輸入側與輸出側串接(jie)適當的(de)(de)(de)電(dian)(dian)(dian)(dian)抗器(qi)(qi)(qi)(qi),也可(ke)以設置 諧(xie)波(bo)(bo)(bo)(bo)(bo)濾(lv)(lv)波(bo)(bo)(bo)(bo)(bo)器(qi)(qi)(qi)(qi),但濾(lv)(lv)波(bo)(bo)(bo)(bo)(bo)器(qi)(qi)(qi)(qi)必須(xu)采用(yong)(yong)LC類型(xing)濾(lv)(lv)波(bo)(bo)(bo)(bo)(bo)方式的(de)(de)(de)。 這樣既增大了電(dian)(dian)(dian)(dian)源(yuan)(yuan)容(rong)(rong)量(liang)(liang)或負載(zai)阻抗,又可(ke)以起到抑(yi)制諧(xie)波(bo)(bo)(bo)(bo)(bo)的(de)(de)(de)目(mu)的(de)(de)(de)。 (2)具有(you)(you)進相(xiang)電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)的(de)(de)(de)系統(tong) 對(dui)于(yu)變頻(pin)(pin)器(qi)(qi)(qi)(qi)電(dian)(dian)(dian)(dian)源(yuan)(yuan)具有(you)(you)進相(xiang)電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)的(de)(de)(de)系統(tong),由于(yu)高次(ci)(ci)諧(xie)波(bo)(bo)(bo)(bo)(bo)電(dian)(dian)(dian)(dian)流(liu)會使(shi)電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)的(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)增加, 容(rong)(rong)易(yi)引起電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)嚴(yan)重發(fa)熱,故必須(xu)在電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)前(qian)串接(jie)電(dian)(dian)(dian)(dian)抗器(qi)(qi)(qi)(qi),用(yong)(yong)于(yu)減(jian)小諧(xie)波(bo)(bo)(bo)(bo)(bo)分(fen)量(liang)(liang)。變頻(pin)(pin)器(qi)(qi)(qi)(qi)輸 入電(dian)(dian)(dian)(dian)源(yuan)(yuan)端串聯電(dian)(dian)(dian)(dian)抗器(qi)(qi)(qi)(qi)的(de)(de)(de)方法。所加設的(de)(de)(de)電(dian)(dian)(dian)(dian)抗器(qi)(qi)(qi)(qi)的(de)(de)(de)電(dian)(dian)(dian)(dian)感量(liang)(liang)必須(xu)經過合理的(de)(de)(de)計算，以防止產生IC振蕩。
