使用西門(mén)子6SE70變頻器(135KW)一拖二電機(jī)方式(2*45KW)驅(qū)動(dòng)翻車(chē)機(jī),變頻器開(kāi)環(huán)控制,翻車(chē)機(jī)定位置控制采用接近開(kāi)關(guān)定位。
在一次翻車(chē)機(jī)設(shè)備改造中,需控制軟件升級(jí),翻車(chē)機(jī)需變頻器功率放大,用于滿足生產(chǎn)產(chǎn)量的需要,設(shè)備改造由廠家全包,在設(shè)備廠家調(diào)試過(guò)程中,廠家派來(lái)一年青工程師,基礎(chǔ)自動(dòng)化與傳動(dòng)一個(gè)人全包,年青的工程師忙了幾天后,總個(gè)電氣系統(tǒng)也準(zhǔn)備得差不多了,準(zhǔn)備測(cè)試傳動(dòng)部分時(shí),由于年青工程師經(jīng)驗(yàn)不足,在對(duì)6SE70變頻器初次上電時(shí),未能仔細(xì)檢查變頻器各種接線,而當(dāng)時(shí)年青工程師重點(diǎn)在校對(duì)6SE70變頻器參數(shù),就在這年青工程師對(duì)6SE70變頻器上電一瞬間,6SE70變頻器電源部分瞬間變成一片紅光,還好,年青工程師反映較快,快速切斷6SE70變頻器進(jìn)線電源,所有在場(chǎng)看的人都心跳了,全場(chǎng)一片寧?kù)o,所有人驚呆了,領(lǐng)導(dǎo)急了,打破了寧?kù)o,忙問(wèn)年青工程師出什么問(wèn)題了,年青工程師由于經(jīng)驗(yàn)也沒(méi)看到過(guò)這種情況,估計(jì)當(dāng)時(shí)的他,心跳比看的人還要跳得快,呵呵!

他回答領(lǐng)導(dǎo),說(shuō)要跟他的領(lǐng)導(dǎo)匯報(bào)才知道,年青工程師忙著給家里的領(lǐng)導(dǎo)打電話去了,后來(lái)得知,因6SE70變頻器配有制動(dòng)單元,由于制動(dòng)單元DC+,DC—與6SE70變頻器直流母線接反造成的,仔細(xì)一看制動(dòng)單元主接線圖可見(jiàn),6SE70變頻器直流母線電源580V的直流電壓通過(guò)制動(dòng)單元的續(xù)流二極管直接放電,勢(shì)必會(huì)造成電源部分的預(yù)充電阻過(guò)大電流,最終導(dǎo)致變頻器預(yù)充限流電阻燒紅。后來(lái)廠家派來(lái)一個(gè)有經(jīng)驗(yàn)的工程師到現(xiàn)場(chǎng)指導(dǎo),由于趕進(jìn)度,并借來(lái)新的6SE70變頻器繼續(xù)調(diào)試,另外因6SE70變頻器在第一次上電過(guò)程中出現(xiàn)一片紅的現(xiàn)象,我單位要求更換新的6SE70變頻器,通過(guò)雙方單位責(zé)任人溝通,最后由廠家請(qǐng)西門(mén)子6SE70變頻器維修專家?guī)浼?,帶工具到現(xiàn)場(chǎng)來(lái)診斷該6SE70變頻器,等了維修工程師一天后,維修工程師從武漢出發(fā)趕到現(xiàn)場(chǎng),記得當(dāng)時(shí)西門(mén)子維修專家?guī)еA(yù)充電電阻,一個(gè)西門(mén)子6SE70變頻器測(cè)試盒,開(kāi)始工作了,首選 更換了6SE70變頻器預(yù)充電電阻,然后用6SE70變頻器測(cè)試盒對(duì)6SE70變頻器做了一個(gè)全身體檢,記憶憂心,當(dāng)時(shí)維修工程師給6SE70變頻器直流母線施加直流電源24V,測(cè)試各IGBT工作情況,然后維修工程師對(duì)總個(gè)6SE70變頻器做了個(gè)空載運(yùn)行試驗(yàn)后,將設(shè)備交由我廠保管,就說(shuō)到這里吧
