西(xi)門子(zi)6SE70整(zheng)流柜運行時報F031診斷(1)
故障現象
整(zheng)流柜報f031故障,變頻不能啟動,檢查后發現,整(zheng)流柜左起第二個保(bao)險560a斷(duan),逆變柜500a四(si)個保(bao)險全斷(duan)。
故障分析(xi)及處(chu)理(2)
f031故障(zhang)代(dai)碼的含(han)義是:可控硅(gui)(gui)支路熔斷器損壞,首先做外觀(guan)(guan)檢(jian)(jian)查(cha)(cha)及用萬用表測量可控硅(gui)(gui)、igbt等(deng)部(bu)(bu)件(jian),檢(jian)(jian)查(cha)(cha)結果正(zheng)常(chang)。更換(huan)保險后(hou)(hou)重新通電(dian),啟(qi)動變(bian)(bian)頻(pin)(pin)器,電(dian)機(ji)運行(xing)在20hz后(hou)(hou),逆變(bian)(bian)柜4個(ge)(ge)保險全斷,整(zheng)流柜保險左起第(di)2個(ge)(ge),第(di)5個(ge)(ge)斷,再次檢(jian)(jian)查(cha)(cha)電(dian)機(ji)及變(bian)(bian)頻(pin)(pin)器,測量結果全部(bu)(bu)正(zheng)常(chang),此時維修工作陷入困境,之后(hou)(hou)繼續(xu)更換(huan)保險進行(xing)觀(guan)(guan)察(cha),啟(qi)動變(bian)(bian)頻(pin)(pin)后(hou)(hou),發現逆變(bian)(bian)柜與整(zheng)流柜之間直流母線排連(lian)接處有打火現象,檢(jian)(jian)查(cha)(cha)后(hou)(hou)發現母線排連(lian)接處螺栓松(song)動,更換(huan)螺栓后(hou)(hou),變(bian)(bian)頻(pin)(pin)器正(zheng)常(chang)工作。從這個(ge)(ge)故障(zhang)可以看出,因為(wei)鉆機(ji)需要不斷搬遷,造成變(bian)(bian)頻(pin)(pin)柜內緊(jin)固件(jian)松(song)動,在變(bian)(bian)頻(pin)(pin)柜日常(chang)維護中應加強對重點連(lian)接部(bu)(bu)位檢(jian)(jian)查(cha)(cha)工作。
