　　  二(er). 日常檢查事項(xiang)

　　  高(gao)(gao)壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)頻(pin)(pin)(pin)(pin)(pin)器(qi)(qi)(qi)(qi)上電(dian)(dian)(dian)之前應先檢(jian)查周圍環(huan)境的(de)(de)(de)溫度(du)及(ji)濕度(du)，溫度(du)過高(gao)(gao)會導(dao)(dao)致高(gao)(gao)壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)頻(pin)(pin)(pin)(pin)(pin)器(qi)(qi)(qi)(qi)過熱報警(jing)，嚴重的(de)(de)(de)會直接導(dao)(dao)致高(gao)(gao)壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)頻(pin)(pin)(pin)(pin)(pin)器(qi)(qi)(qi)(qi)功(gong)率器(qi)(qi)(qi)(qi)件損壞，微(wei)電(dian)(dian)(dian)網電(dian)(dian)(dian)路(lu)短(duan)(duan)路(lu);空氣(qi)過于潮濕會導(dao)(dao)致高(gao)(gao)壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)頻(pin)(pin)(pin)(pin)(pin)器(qi)(qi)(qi)(qi)內(nei)部直接短(duan)(duan)路(lu)。在高(gao)(gao)壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)頻(pin)(pin)(pin)(pin)(pin)器(qi)(qi)(qi)(qi)運(yun)行時(shi)要注意其冷卻系(xi)統是(shi)否(fou)正常，高(gao)(gao)壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)頻(pin)(pin)(pin)(pin)(pin)器(qi)(qi)(qi)(qi)的(de)(de)(de)七大(da)(da)應用領域如：風(feng)(feng)道排風(feng)(feng)是(shi)否(fou)流(liu)暢(chang)，風(feng)(feng)機是(shi)否(fou)有異(yi)常聲音(yin)。一般(ban)防(fang)護等級(ji)比較高(gao)(gao)的(de)(de)(de)高(gao)(gao)壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)頻(pin)(pin)(pin)(pin)(pin)器(qi)(qi)(qi)(qi)如：IP20以(yi)上的(de)(de)(de)高(gao)(gao)壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)頻(pin)(pin)(pin)(pin)(pin)器(qi)(qi)(qi)(qi)可(ke)直接敞開安裝(zhuang)，IP20以(yi)下(xia)的(de)(de)(de)高(gao)(gao)壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)頻(pin)(pin)(pin)(pin)(pin)器(qi)(qi)(qi)(qi)一般(ban)應是(shi)柜式安裝(zhuang)，所以(yi)變(bian)(bian)(bian)頻(pin)(pin)(pin)(pin)(pin)柜散(san)熱效果如何(he)將直接影響高(gao)(gao)壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)頻(pin)(pin)(pin)(pin)(pin)器(qi)(qi)(qi)(qi)的(de)(de)(de)正常運(yun)行，高(gao)(gao)壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)頻(pin)(pin)(pin)(pin)(pin)器(qi)(qi)(qi)(qi)的(de)(de)(de)排風(feng)(feng)系(xi)統如風(feng)(feng)扇(shan)旋轉是(shi)否(fou)流(liu)暢(chang)，進風(feng)(feng)口(kou)是(shi)否(fou)有灰塵(chen)及(ji)堵塞物都是(shi)我們(men)日常檢(jian)查不(bu)可(ke)忽略的(de)(de)(de)地方。電(dian)(dian)(dian)動(dong)機電(dian)(dian)(dian)抗器(qi)(qi)(qi)(qi)，變(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)(qi)等是(shi)否(fou)過熱，有異(yi)味;高(gao)(gao)壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)頻(pin)(pin)(pin)(pin)(pin)器(qi)(qi)(qi)(qi)及(ji)馬(ma)達是(shi)否(fou)有異(yi)常響聲;高(gao)(gao)壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)頻(pin)(pin)(pin)(pin)(pin)器(qi)(qi)(qi)(qi)面板電(dian)(dian)(dian)流(liu)顯示是(shi)否(fou)偏大(da)(da)或電(dian)(dian)(dian)流(liu)變(bian)(bian)(bian)化幅度(du)太(tai)大(da)(da)，輸出UVW三相電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)與電(dian)(dian)(dian)流(liu)是(shi)否(fou)平衡。

　　三. 定期保養(yang)

　　  清掃空氣過濾器(qi)(qi)冷卻風道及內(nei)部灰塵。檢(jian)查螺絲釘，微(wei)電網螺栓以及即插件等(deng)是(shi)否(fou)(fou)松動，輸入輸出(chu)電抗器(qi)(qi)的(de)對地及相間(jian)電阻(zu)是(shi)否(fou)(fou)有短路(lu)(lu)現(xian)象，正常應大于幾十(shi)兆歐(ou)。導體(ti)及絕緣體(ti)是(shi)否(fou)(fou)有腐蝕現(xian)象，如(ru)有要及時(shi)用酒(jiu)精(jing)擦試干凈。如(ru)條件允許的(de)情況下(xia)，要用示(shi)波器(qi)(qi)測(ce)量(liang)開關電源輸出(chu)各(ge)路(lu)(lu)電壓的(de)平穩性，如(ru)：5V，12V，15V，24V等(deng)電壓。測(ce)量(liang)驅動電路(lu)(lu)各(ge)路(lu)(lu)波形(xing)的(de)方波是(shi)否(fou)(fou)有畸變(bian)。UVW相間(jian)波形(xing)是(shi)否(fou)(fou)為正弦(xian)波。接觸器(qi)(qi)的(de)觸點是(shi)否(fou)(fou)有打火痕跡，嚴重的(de)要跟換同型(xing)號(hao)或大于原容量(liang)的(de)新品(pin);確認(ren)控制電壓的(de)正確性，微(wei)電網進行順序保護動作試驗;確認(ren)保護顯示(shi)回路(lu)(lu)無異常;確認(ren)高壓變(bian)頻器(qi)(qi)在單獨運行時(shi)輸出(chu)電壓的(de)平衡度。建議(yi)定期檢(jian)查，應一年(nian)進行一次。

　　  四. 備件的更換

　　  高壓變(bian)頻器由多種部件(jian)組成(cheng)，高壓變(bian)頻器的(de)七大應用領(ling)域其(qi)中(zhong)一些部件(jian)經(jing)長期工作后其(qi)性能會逐漸降低，老化，這也(ye)是(shi)高壓變(bian)頻器發生故障的(de)主要原因，為(wei)了保證設備長期的(de)正常運轉(zhuan)，下(xia)列器件(jian)應定(ding)期更(geng)換(huan)：

　　  1，冷卻(que)風扇

　　  高(gao)壓(ya)(ya)變(bian)頻(pin)(pin)器(qi)(qi)(qi)(qi)的功率模塊(kuai)是發熱 嚴重的器(qi)(qi)(qi)(qi)件，其連續工作所產生(sheng)的熱量 須要(yao)(yao)及時(shi)(shi)排出，一(yi)般(ban)(ban)風(feng)扇(shan)的壽命(ming)大約為10Kh—40Kh。按高(gao)壓(ya)(ya)變(bian)頻(pin)(pin)器(qi)(qi)(qi)(qi)連續運行折算為2—3年就要(yao)(yao)更換(huan)(huan)一(yi)次風(feng)扇(shan)，高(gao)壓(ya)(ya)變(bian)頻(pin)(pin)器(qi)(qi)(qi)(qi)-高(gao)壓(ya)(ya)變(bian)頻(pin)(pin)器(qi)(qi)(qi)(qi)維(wei)修(xiu)-高(gao)壓(ya)(ya)變(bian)頻(pin)(pin)器(qi)(qi)(qi)(qi)維(wei)保-儲能系(xi)統-儲能雙向變(bian)流(liu)器(qi)(qi)(qi)(qi)PCS-維(wei)斯克電氣(qi)(山東)有(you)(you)限(xian)公司直接冷卻風(feng)扇(shan)有(you)(you)二線(xian)(xian)和三線(xian)(xian)之(zhi)分，二線(xian)(xian)風(feng)扇(shan)其中一(yi)線(xian)(xian)為正極，另一(yi)線(xian)(xian)為負極，更換(huan)(huan)時(shi)(shi)不(bu)(bu)要(yao)(yao)接錯;三線(xian)(xian)風(feng)扇(shan)除了正，負極外還(huan)有(you)(you)一(yi)根檢測(ce)線(xian)(xian)，更換(huan)(huan)時(shi)(shi)千萬注意，否則(ze)會(hui)引起(qi)高(gao)壓(ya)(ya)變(bian)頻(pin)(pin)器(qi)(qi)(qi)(qi)過熱報警。交流(liu)風(feng)扇(shan)一(yi)般(ban)(ban)為220V，380V之(zhi)分，更換(huan)(huan)時(shi)(shi)電壓(ya)(ya)等級不(bu)(bu)要(yao)(yao)搞錯。

　　  2，濾波(bo)電容:

　　  中間(jian)電路濾波(bo)(bo)電容：又稱電解電容，其主要(yao)作用(yong)就是平滑直流(liu)電壓(ya)，吸收(shou)直流(liu)中的(de)(de)低頻諧波(bo)(bo)，它的(de)(de)連續工作產生的(de)(de)熱(re)量(liang)(liang)(liang)加上高(gao)壓(ya)變頻器本身(shen)產生的(de)(de)熱(re)量(liang)(liang)(liang)都會加快其電解液的(de)(de)干(gan)涸，直接影響(xiang)其容量(liang)(liang)(liang)的(de)(de)大小。正常情(qing)況下(xia)電容的(de)(de)使用(yong)壽命為5年。建(jian)議每(mei)年定期檢查電容容量(liang)(liang)(liang)一(yi)次，一(yi)般其容量(liang)(liang)(liang)減少(shao)20%以上應更換.
