西門子6RA70沒有任何顯示,故障維修處理:控制器在停機降速過程中,多次出現模塊直流過壓故障,導致將用戶高壓開關跳掉。用戶母線電壓過高,6KV電源實際母線達6.3KV以上,10KV電源實際母線達10.3KV以上,母線電壓加到變頻器上時模塊輸入電壓過高,模塊報直流母線過壓。變頻器在啟動過程中,大約到運行到4HZ左右,變頻器直流母線過壓。
故障原(yuan)因:變頻器(qi)(qi)在(zai)停機(ji)(ji)過(guo)程由(you)于降速時間太快,使(shi)得電(dian)機(ji)(ji)處于發電(dian)機(ji)(ji)狀態,電(dian)機(ji)(ji)回(hui)饋能量到(dao)模塊的直流(liu)母(mu)線產生泵升電(dian)壓(ya),從(cong)而(er)使(shi)直流(liu)母(mu)線電(dian)壓(ya)過(guo)高(gao)。由(you)于現場變壓(ya)器(qi)(qi)出廠標準接(jie)線是10KV和6KV,母(mu)線電(dian)壓(ya)如(ru)果超過(guo)10.3KV或(huo)6.3KV,就會使(shi)變壓(ya)器(qi)(qi)輸出電(dian)壓(ya)過(guo)高(gao),從(cong)而(er)使(shi)模塊的母(mu)線電(dian)壓(ya)升高(gao)造成(cheng)過(guo)壓(ya)。同一位置的不同相模塊光(guang)(guang)纖(xian)接(jie)反(比如(ru)A4與B4光(guang)(guang)纖(xian)接(jie)反),造成(cheng)其相電(dian)壓(ya)輸出過(guo)壓(ya)。
