西門子直流控制器啟動合閘跳保險當天搞好；啟動合閘跳保險故障(zhang)處理；

在控制器使用過程(cheng)中，跳(tiao)閘(zha)(zha)是(shi)比較(jiao)常見的變頻(pin)器故障(zhang)。下(xia)面(mian)我們來了解一下(xia)一bai般情況(kuang)下(xia)變頻(pin)器跳(tiao)閘(zha)(zha)可能的原(yuan)因和(he)處(chu)理方法。

一(yi)、電(dian)源故障(zhang)引起的變頻(pin)器(qi)跳(tiao)閘

電(dian)(dian)(dian)源(yuan)瞬間斷電(dian)(dian)(dian)或電(dian)(dian)(dian)壓(ya)(ya)(ya)低(di)落出現“欠電(dian)(dian)(dian)壓(ya)(ya)(ya)”顯示，或這瞬間過(guo)電(dian)(dian)(dian)壓(ya)(ya)(ya)出現“過(guo)電(dian)(dian)(dian)壓(ya)(ya)(ya)”顯示，都可能會引(yin)起變頻器跳閘(zha)停機，這種情(qing)況下(xia)電(dian)(dian)(dian)源(yuan)恢復正(zheng)常后即可重新起動。

二、外(wai)部故障(zhang)引起(qi)的變頻器跳閘

如果輸(shu)入信號斷(duan)路，輸(shu)出線路開路、斷(duan)相(xiang)、短路、接地(di)或絕緣電(dian)阻很低(di)，電(dian)動機故障(zhang)或過載等，變頻器即(ji)顯示“外(wai)部”故障(zhang)而跳(tiao)閘(zha)停(ting)機，經排(pai)除故障(zhang)后，即(ji)可重新啟用(yong)。

三、內部故障引起的(de)變頻器跳閘

如果內部風扇斷路或過(guo)熱，熔斷器(qi)斷路，器(qi)件過(guo)熱，存儲器(qi)錯誤，CPU故障等，可切換至(zhi)工(gong)頻運行(xing)(xing)，不致影響(xiang)生(sheng)產，待(dai)內部故障排除后(hou)，即可恢復變頻運行(xing)(xing)。

變頻(pin)一旦發(fa)生內部故障，如果在保修(xiu)期(qi)內，應(ying)該盡快(kuai)通知廠家或廠家代理負(fu)責保修(xiu)。根(gen)據故障顯(xian)示的(de)類(lei)別和數據進行下列檢查(cha)。

1.打開機箱后，首(shou)先檢(jian)查內部有(you)否有(you)斷(duan)線(xian)、虛焊、燒(shao)焦(jiao)氣味(wei)或變(bian)質(zhi)變(bian)形的(de)元器件，如有(you)則(ze)及(ji)時(shi)做相應處理。

2.用(yong)(yong)萬用(yong)(yong)表檢測電阻的(de)阻值和二極管(guan)、開關(guan)管(guan)及模塊通斷(duan)(duan)電阻，判斷(duan)(duan)是(shi)否開斷(duan)(duan)或擊(ji)穿。如有，則按原(yuan)標(biao)稱值和耐(nai)壓值更換，或者(zhe)用(yong)(yong)同(tong)類型的(de)代替。

3.用(yong)雙(shuang)蹤示波(bo)器(qi)(qi)檢測(ce)各工作(zuo)點波(bo)形，采用(yong)逐級排除法判斷故障(zhang)位置和(he)元(yuan)器(qi)(qi)件。

控制器維修方法應當以生產設備合用為標準關電源故障在第二級開關電源的設計上電路結構特點。可以分為振蕩和穩壓控制電路，推動和逆變輸出三個部分。分故障范圍和維修。那么開關電源故障的檢修難點和要求有哪些？處于正常還是非正常的狀態。
