交流變頻電源的日常檢查不要忘記溫度和濕度
變頻(pin)電(dian)(dian)源(yuan)上(shang)電(dian)(dian)之(zhi)前首要應(ying)該先查看周圍(wei)環(huan)境(jing)的溫度及濕(shi)度，溫度過高會(hui)導致(zhi)變頻(pin)電(dian)(dian)源(yuan)過熱報警(jing)，嚴峻(jun)的會(hui)直接導致(zhi)變頻(pin)電(dian)(dian)源(yuan)功率(lv)器件損壞、電(dian)(dian)路短路；空(kong)氣(qi)過于(yu)潮濕(shi)會(hui)導致(zhi)變頻(pin)電(dian)(dian)源(yuan)內部直接短路。
在變(bian)(bian)頻電(dian)(dian)源(yuan)(yuan)運(yun)行時特別要注意其(qi)冷卻體(ti)系是否(fou)(fou)(fou)正常，如(ru)：風(feng)道(dao)排(pai)風(feng)是否(fou)(fou)(fou)流(liu)暢，風(feng)機是否(fou)(fou)(fou)有(you)異常聲音。一般防護等級比較高(gao)的(de)(de)變(bian)(bian)頻電(dian)(dian)源(yuan)(yuan)如(ru)：IP20以上的(de)(de)變(bian)(bian)頻電(dian)(dian)源(yuan)(yuan)可(ke)直接敞開裝(zhuang)(zhuang)置，IP20以下的(de)(de)變(bian)(bian)頻電(dian)(dian)源(yuan)(yuan)一般應是柜(ju)式裝(zhuang)(zhuang)置，所以變(bian)(bian)頻柜(ju)散(san)熱作(zuo)用如(ru)何將直接影響(xiang)變(bian)(bian)頻電(dian)(dian)源(yuan)(yuan)的(de)(de)正常運(yun)行，變(bian)(bian)頻電(dian)(dian)源(yuan)(yuan)的(de)(de)排(pai)風(feng)體(ti)系如(ru)電(dian)(dian)扇(shan)旋(xuan)轉是否(fou)(fou)(fou)流(liu)暢，進風(feng)口(kou)是否(fou)(fou)(fou)有(you)灰塵及阻塞物都是我們(men)日常查看不行疏忽(hu)的(de)(de)地方。
電(dian)(dian)動機(ji)電(dian)(dian)抗器、變(bian)頻(pin)電(dian)(dian)源(yuan)等(deng)是(shi)否(fou)(fou)過(guo)熱(re)，有異(yi)味(wei)；變(bian)頻(pin)電(dian)(dian)源(yuan)及馬(ma)達是(shi)否(fou)(fou)有異(yi)常響聲(sheng)；變(bian)頻(pin)電(dian)(dian)源(yuan)面板電(dian)(dian)流(liu)顯現(xian)是(shi)否(fou)(fou)偏大(da)或(huo)電(dian)(dian)流(liu)變(bian)化幅(fu)度太(tai)大(da)，輸出UVW三相電(dian)(dian)壓與電(dian)(dian)流(liu)是(shi)否(fou)(fou)平衡等(deng)都是(shi)日常需(xu)求查看的事項。
