Inverter intermediate frequency furnaces must have advantages over parallel intermediate frequency furnaces

1. I-thyristor parallel circuit iyi-parallel resonance intermediate frequency furnace. Ngesikhathi sokuncibilika, ikakhulukazi ukuncibilika kwe-aluminium, ithusi nezinye izinto, umthwalo ulula kakhulu, futhi ukuphuma kwawo kwamandla kuncane kakhulu, okuhlobene kakhulu nemvelo yomthwalo, ngakho-ke ijubane layo lokuncibilika lihamba kancane , Ubunzima ekushisiseni. Isithando somlilo esincibilikisa ifrikhwensi emaphakathi ye-thyristor silungisa amandla ngokushintshashintsha imvamisa, ngakho-ke asithintwa kancane yimvelo yomthwalo. Yonke inqubo yokuncibilika icishe igcine ukuphuma kwamandla okungashintshi. Ngoba i-resonance yochungechunge, okungukuthi, i-voltage resonance, i-voltage ye-coil yokungeniswa iphezulu futhi yamanje incane, ngakho Ukulahlekelwa kwamandla kuncane.

2. Ngenxa yokuthi i-inverter yochungechunge, isici samandla siphezulu futhi ama-harmonics amancane, ngakho-ke asikho isidingo sokufaka idivayisi yesinxephezelo samandla asebenzayo. Lokhu kungonga abasebenzisi imali eningi, futhi futhi kuyithuluzi elithuthukisiwe elikhuthazwa kakhulu umnyango wokuphakelwa kukagesi.

3. Uma uchungechunge lwesithando somlilo esiphakathi sisebenza, isilungisisi sihlala sisebenza esimweni sokusebenza ngokugcwele, futhi amandla okukhiphayo wesifunda se-inverter ashintshwa ngokulawula imvamisa yokushaya kwe-inverter trigger. Futhi umthamo wamanje uyigagasi le-sine, ngakho-ke uchungechunge lwesithando somlilo esimaphakathi ngeke lungcolise kakhulu igridi yamandla ngama-harmonics aphezulu, futhi isici samandla siphezulu. Ama-inverter ahambisanayo awakwazi ukufeza ukusebenza kokulungiswa kwamandla okuzenzakalelayo kokukodwa kuya kokubili, ngoba ukulungiswa kwamandla okunikezwa kwamandla okuguquguqukayo okuhambisanayo kungafinyelelwa kuphela ngokulungisa i-voltage ephumayo yebhuloho elilungisa kabusha. Lapho ibhuloho elihambisanayo le-inverter rectifier lisebenza ku-voltage ephansi, i-engeli ye-rectifier conduction incane kakhulu. Esimweni, isici samandla semishini sizoba phansi kakhulu, futhi i-parallel inverter load current iyigagasi lesikwele, elizongcolisa kakhulu igridi. Uma amandla elungiswa ngokulungisa i-angle yokucindezela emuva kwe-inverter, ububanzi bokulungiswa kwamandla buncane kakhulu. Ngakho-ke, izinsiza zamandla ze-inverter ezihambisanayo azikwazi ukufeza ukusebenza okukodwa kuya kokubili.
