ABB變(bian)頻(pin)器維修(xiu)方(fang)法需要(yao)掌握(wo)得當,因為變(bian)頻(pin)器由(you)多種(zhong)部件組成,其中某些部件經長期工作后其性能會(hui)逐漸降低、老化(hua),這是產生故障的主要(yao)原因,為了保證(zheng)設備(bei)長期的正(zheng)常運轉,一些易損器件應不定期更換,如電容、散熱風扇等。
ABB直流電機控制器維修-
ABB直流電機控制器較常見故(gu)障有(you)驅(qu)動厚(hou)膜損(sun)壞(huai)。此(ci)驅(qu)動厚(hou)膜已(yi)包(bao)(bao)含驅(qu)動電路,還包(bao)(bao)括短路檢測(ce)、 IGBT模塊檢測(ce)、過流(liu)檢測(ce)等,具有(you)良好保護(hu)功(gong)能。ACS500大功(gong)率模塊很少(shao)損(sun)壞(huai)。維修(xiu)中遇到驅(qu)動厚(hou)膜損(sun)壞(huai),在沒有(you)配件(jian)(jian)情況下,只能對厚(hou)膜進(jin)行維修(xiu),厚(hou)膜元(yuan)(yuan)器件(jian)(jian)都焊接于(yu)陶瓷(ci)片(pian)上(shang)(shang),散熱相(xiang)當快,特別注意不要(yao)長時(shi)間把烙(luo)鐵加熱于(yu)元(yuan)(yuan)器件(jian)(jian)上(shang)(shang),而(er)導致器件(jian)(jian)損(sun)壞(huai)。受到使用時(shi)間限定,ACS500散熱風(feng)(feng)扇也會出現故(gu)障,常見現象是(shi)(shi)上(shang)(shang)電后只聽到“嗡嗡"聲(sheng)音(yin),但(dan)風(feng)(feng)扇不轉(zhuan),這類軸流(liu)風(feng)(feng)扇的(de)風(feng)(feng)扇線圈(quan)和軸承大多時(shi)候是(shi)(shi)好的(de),通常是(shi)(shi)偏轉(zhuan)電容發生故(gu)障,更換后就可以恢復(fu)正常。
ABB直(zhi)流電機控制器經常(chang)會遇到開關(guan)(guan)電(dian)(dian)(dian)源(yuan)損(sun)壞。變(bian)頻器開關(guan)(guan)電(dian)(dian)(dian)源(yuan)采用(yong)近似UC3844功能的(de)LT1244波形發(fa)生(sheng)(sheng)器集(ji)成塊(kuai),受工(gong)作(zuo)電(dian)(dian)(dian)壓突(tu)變(bian),以及開關(guan)(guan)電(dian)(dian)(dian)源(yuan)所帶(dai)負(fu)載損(sun)壞,而導致此集(ji)成塊(kuai)損(sun)壞時有發(fa)生(sheng)(sheng),當使用(yong)較長年數,電(dian)(dian)(dian)解電(dian)(dian)(dian)容也到了(le)它(ta)使用(yong)的(de)年限,那用(yong)于濾波電(dian)(dian)(dian)容也就成了(le)開關(guan)(guan)電(dian)(dian)(dian)源(yuan)損(sun)壞直接(jie)原因(yin)。維(wei)修(xiu)中(zhong)會遇到ACS300變(bian)頻器整流橋經常(chang)損(sun)壞,因(yin)為選用(yong)國際整流器公司一款*緊湊三相全橋整流器,體積和帶(dai)載電(dian)(dian)(dian)流都(dou)較小,散熱(re)性能較差,使用(yong)一段時間后就會出現損(sun)壞。ACS300主控板(ban)發(fa)生(sheng)(sheng)故障(zhang)(zhang)(zhang)(zhang)幾率也是相當高(gao),控制(zhi)盤與主板(ban)之間通訊故障(zhang)(zhang)(zhang)(zhang),主板(ban)CPU故障(zhang)(zhang)(zhang)(zhang)時有發(fa)生(sheng)(sheng),維(wei)修(xiu)此類故障(zhang)(zhang)(zhang)(zhang)有一定難(nan)度。ACS300選用(yong)了(le)三菱IPM模(mo)塊(kuai),相對(dui)來(lai)說故障(zhang)(zhang)(zhang)(zhang)幾率較低,模(mo)塊(kuai)損(sun)壞,只能更換,但更換前必須保證(zheng)驅動電(dian)(dian)(dian)路正常(chang)。
ABB直流電機控(kong)制器維修-日常檢查
變(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)上電之前應(ying)先(xian)檢測(ce)周(zhou)圍環(huan)境的溫(wen)(wen)度及濕度,溫(wen)(wen)度過(guo)高(gao)會(hui)(hui)導(dao)致變(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)過(guo)熱報(bao)警,嚴(yan)重時會(hui)(hui)直接導(dao)致變(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)功率器(qi)(qi)(qi)件(jian)損壞、電路(lu)短路(lu);空(kong)氣過(guo)于潮濕會(hui)(hui)導(dao)致變(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)內(nei)部直接短路(lu),在變(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)運行時要注意其冷卻系(xi)統是否正常。
ABB直流電機控制器(qi)維修-定期保養
清掃空氣過濾器(qi)冷卻風道及(ji)(ji)內部灰塵。檢查螺絲(si)釘、螺栓以及(ji)(ji)即插件等是否(fou)松動,輸入輸出電抗器(qi)的對(dui)地及(ji)(ji)相間電阻是否(fou)有短(duan)路現象,正(zheng)常應(ying)大于(yu)幾十兆歐(ou)。導體及(ji)(ji)絕緣體是否(fou)有腐蝕(shi)現象,如有要及(ji)(ji)時用酒精擦拭干凈。
5、在條(tiao)件允許的情況下,要用示波器(qi)(qi)測量(liang)開(kai)關電(dian)源輸出各電(dian)路(lu)電(dian)壓(ya)的平穩性,如(ru):5V.12V、15V、24V等電(dian)壓(ya)。測量(liang)驅(qu)動器(qi)(qi)電(dian)路(lu)各路(lu)波形的方(fang)法是(shi)否有畸變。UVW相(xiang)間(jian)波形是(shi)否正弦波,接觸器(qi)(qi)的觸點是(shi)否有打(da)火痕跡,損壞的要更換同型號或大(da)于原容量(liang)的新品(pin)。
ABB變頻器維修方法(fa)在于(yu)(yu)平時多檢(jian)(jian)查,防(fang)患于(yu)(yu)未然(ran),大檢(jian)(jian)查時間應至少半(ban)年進行一次。
