檢查電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)和電(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)基本步驟：1. 使(shi)用(yong)萬用(yong)表(biao)或類(lei)似的(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)表(biao)測量電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)以(yi)(yi)了(le)解變(bian)(bian)頻(pin)(pin)器(qi)(qi)的(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)范(fan)(fan)圍(wei)。一般來(lai)說，變(bian)(bian)頻(pin)(pin)器(qi)(qi)工作時(shi)(shi)(shi)需(xu)要(yao)較(jiao)穩定的(de)(de)(de)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，通常(chang)要(yao)求±10%的(de)(de)(de)精度和電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)范(fan)(fan)圍(wei)。可(ke)以(yi)(yi)使(shi)用(yong)萬用(yong)表(biao)將電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)與變(bian)(bian)頻(pin)(pin)器(qi)(qi)的(de)(de)(de)標準電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)進(jin)(jin)行(xing)比較(jiao)。2. 在(zai)變(bian)(bian)頻(pin)(pin)器(qi)(qi)正常(chang)工作情況下，可(ke)以(yi)(yi)使(shi)用(yong)功率計檢測電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)范(fan)(fan)圍(wei)。測量電(dian)(dian)(dian)(dian)流(liu)(liu)時(shi)(shi)(shi)需(xu)要(yao)注意電(dian)(dian)(dian)(dian)氣測試的(de)(de)(de)安(an)全性(xing)并采取適當的(de)(de)(de)措施。如果發現錯(cuo)誤或故障，需(xu)停止大功率試驗。3. 如果已經排(pai)除了(le)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)或電(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)問題(ti)，仍然存在(zai)故障，那么需(xu)要(yao)進(jin)(jin)一步檢查變(bian)(bian)頻(pin)(pin)器(qi)(qi)的(de)(de)(de)控(kong)制(zhi)電(dian)(dian)(dian)(dian)路和驅動器(qi)(qi)。廣(guang)州(zhou)發那科(ke)變(bian)(bian)頻(pin)(pin)器(qi)(qi)維(wei)修(xiu)變(bian)(bian)頻(pin)(pin)器(qi)(qi)維(wei)修(xiu)需(xu)要(yao)在(zai)維(wei)修(xiu)過程中及時(shi)(shi)(shi)處理必要(yao)的(de)(de)(de)金屬加工和焊接。

變(bian)頻器(qi)維修(xiu)的(de)注意(yi)事(shi)項：1、變(bian)頻器(qi)的(de)使用/維修(xiu)必(bi)須由相(xiang)應(ying)(ying)的(de)合格的(de)操(cao)作(zuo)(zuo)人員來進(jin)行(xing)，在進(jin)行(xing)任何(he)工作(zuo)(zuo)之(zhi)前，必(bi)須熟(shu)悉安全資料及安裝、操(cao)作(zuo)(zuo)和維修(xiu)的(de)說明。2、變(bian)頻器(qi)帶有危險(xian)電壓(ya)(ya)(ya)電平，在信號繼電器(qi)上會出現危險(xian)電壓(ya)(ya)(ya)。如果不是由專門受過培(pei)訓(xun)的(de)操(cao)作(zuo)(zuo)人員操(cao)作(zuo)(zuo)，則(ze)會造(zao)成傷(shang)亡、嚴重(zhong)的(de)人身傷(shang)害和重(zhong)大(da)的(de)財產損失。因此，在進(jin)行(xing)維修(xiu)、使用時請一定要遵守使用說明。3、在進(jin)行(xing)觀(guan)察和維修(xiu)工作(zuo)(zuo)之(zhi)前應(ying)(ying)確保交流(liu)電源被(bei)切斷(duan)并(bing)鎖上，而且整流(liu)器(qi)接(jie)地。在交流(liu)電源被(bei)切斷(duan)之(zhi)前，整流(liu)器(qi)和電動機都帶有危險(xian)電壓(ya)(ya)(ya)電平。即(ji)使斷(duan)開了整流(liu)器(qi)接(jie)觸器(qi)，仍存在危險(xian)的(de)電壓(ya)(ya)(ya)。
