描述
回到正題，用案例說一說直流調(diào)速器的大拿，abbdcs產(chǎn)品的兩個(gè)系列的維修心得。
先說abbdcs400系列，abb的直流調(diào)速器，dcs直流調(diào)速器是abb驅(qū)動(dòng)產(chǎn)品的一個(gè)重要產(chǎn)品，產(chǎn)品不但沒有像歐陸590那樣，一代產(chǎn)品用到底。Abb還投入了大量的人力物力，保持著dcs和acs一樣的換代速度，可見abb對(duì)旗下直流調(diào)速器產(chǎn)品的重視程度。abb也是為數(shù)不多，有實(shí)力和西門子6ra系列調(diào)速器直接叫板的品牌。
Abbdcs400直流調(diào)速器在市場上用得相當(dāng)普遍，功率從幾十千瓦到幾百千瓦不等，（這段功率覆蓋范圍相當(dāng)廣，更大的功率更復(fù)雜的應(yīng)用交給了dcs500/600系列完成）。Dcs400在abb的產(chǎn)品中談不上高端，但軟件操作界面友好，上手很快，組態(tài)容易。硬件方便，主要分電源驅(qū)動(dòng)板和應(yīng)用控制板，dcs400系列由于設(shè)計(jì)的原因，電源驅(qū)動(dòng)板還是容易出問題的，更讓人惱火的是，dcs400把勵(lì)磁控制也集成在這個(gè)板上，而dcs400軟件是不支持勵(lì)磁關(guān)閉這個(gè)功能，這給維修帶來了一定的難度。在實(shí)際維修中，abbdcs400由于勵(lì)磁引發(fā)的故障是最多的。還有就是控制電源，這個(gè)板的控制電源次級(jí)取樣相當(dāng)?shù)钠孑猓宦?lián)機(jī)主控板，電源會(huì)產(chǎn)生保護(hù)，但連上主控板維修電源，弄不好會(huì)燒壞主板，那就問題擴(kuò)大，得不償失。
一例：一臺(tái)用戶維修dcs400(500a)4q調(diào)速器，故障是電源打嗝，主板數(shù)碼管明滅不定，客戶送修。我對(duì)電源打嗝的分析分兩步:1后級(jí)有短路，2.取樣電路故障，造成反饋取樣過壓保護(hù)。測后級(jí)阻抗，靜態(tài)阻抗無明顯短接，拔掉勵(lì)磁供電，故障依然，由于不連接主板電源一樣打嗝。
