西門子6SE70風扇壞/熔斷器出售，變(bian)(bian)頻(pin)器(qi)(qi)在運轉中突(tu)然發出爆(bao)炸聲響，同時外接保(bao)險(xian)燒毀，拆機發現(xian)變(bian)(bian)頻(pin)器(qi)(qi)的igbt模(mo)塊損(sun)壞。經過(guo)對相關(guan)板(ban)卡(ka)的測(ce)試，發現(xian)igbt觸發線路損(sun)壞，測(ce)量(liang)其(qi)他板(ban)塊正常。在拆卸變(bian)(bian)頻(pin)器(qi)(qi)板(ban)卡(ka)時發現(xian)其(qi)電源板(ban)和電流檢測(ce)板(ban)上有很多的油污和灰塵(chen)。打開變(bian)(bian)頻(pin)器(qi)(qi)的散(san)熱(re)片(pian)風機，看到散(san)熱(re)片(pian)上也粘(zhan)滿了油污和雜物，將變(bian)(bian)頻(pin)器(qi)(qi)的散(san)熱(re)通道*堵死。由此推斷變(bian)(bian)頻(pin)器(qi)(qi)的IGBT模(mo)塊因散(san)熱(re)不良導致其(qi)損(sun)壞。

維修(xiu)(xiu)過程：首先將(jiang)變(bian)頻(pin)器*拆開，將(jiang)散熱(re)通道(dao)的散熱(re)片(pian)拆下，用(yong)空壓氣體將(jiang)散熱(re)片(pian)清理(li)干凈，同時(shi)將(jiang)變(bian)頻(pin)器內部結構(gou)件和板卡(ka)全部清理(li)干凈。安(an)(an)(an)裝(zhuang)igbt模塊(kuai)，安(an)(an)(an)裝(zhuang)igbt模塊(kuai)時(shi)候(hou)要(yao)按照模塊(kuai)的要(yao)求，順序安(an)(an)(an)裝(zhuang)，力矩適(shi)度。修(xiu)(xiu)理(li)觸發線路，然(ran)后(hou)依次安(an)(an)(an)裝(zhuang)其他器件。安(an)(an)(an)裝(zhuang)結束(shu)后(hou)進行靜態(tai)的測試(shi)，靜態(tai)測試(shi)結果良好后(hou)進行通電測試(shi)和帶負載試(shi)驗。帶負載試(shi)驗合格(ge)，順利完成維修(xiu)(xiu)。
