西門子6SE70風扇壞/熔斷器出售，變頻(pin)器(qi)(qi)在(zai)運(yun)轉中突然發(fa)出爆炸聲響，同時(shi)外接保(bao)險(xian)燒毀(hui)，拆(chai)(chai)機發(fa)現變頻(pin)器(qi)(qi)的igbt模塊(kuai)損壞。經(jing)過(guo)對相關板卡的測試，發(fa)現igbt觸發(fa)線路損壞，測量其(qi)他(ta)板塊(kuai)正常。在(zai)拆(chai)(chai)卸變頻(pin)器(qi)(qi)板卡時(shi)發(fa)現其(qi)電(dian)源板和電(dian)流檢(jian)測板上有很多的油污(wu)和灰(hui)塵。打開變頻(pin)器(qi)(qi)的散(san)熱片風(feng)機，看(kan)到(dao)散(san)熱片上也粘滿了油污(wu)和雜物，將變頻(pin)器(qi)(qi)的散(san)熱通道(dao)*堵死。由此推(tui)斷變頻(pin)器(qi)(qi)的IGBT模塊(kuai)因散(san)熱不良導致其(qi)損壞。

維修(xiu)過(guo)程：首(shou)先將變頻(pin)器*拆開，將散(san)熱(re)(re)(re)通道的(de)散(san)熱(re)(re)(re)片(pian)拆下，用空壓(ya)氣體(ti)將散(san)熱(re)(re)(re)片(pian)清(qing)理(li)干凈，同(tong)時將變頻(pin)器內部結構件(jian)和(he)板卡全部清(qing)理(li)干凈。安(an)裝igbt模塊(kuai)，安(an)裝igbt模塊(kuai)時候要(yao)按照(zhao)模塊(kuai)的(de)要(yao)求，順(shun)序安(an)裝，力(li)矩適度。修(xiu)理(li)觸發線路，然后依次安(an)裝其他器件(jian)。安(an)裝結束后進行靜態(tai)的(de)測試(shi)，靜態(tai)測試(shi)結果良好后進行通電測試(shi)和(he)帶負(fu)載試(shi)驗。帶負(fu)載試(shi)驗合格，順(shun)利完成維修(xiu)。
