Isilawuli Sokushisela Ngokumelana se-MFDC esine-Inverter Emaphakathi

Izinzuzo Eziyinhloko Uma Kuqhathaniswa Nemishini Yokushisela Evamile ye-AC ene-50/60Hz Line-Frequency

1. Ukusebenza Kokulawula

• Ama-welder e-Traditional line-frequency AC aguqulela okukhipha i-transformer yesibili ngokusebenzisa i-thyristor firing angle. Ukuxhumeka ngqo kugridi kuholela ekutheni kube ne-power factor ephansi, umjikelezo wokulungisa ongu-20ms ngaphansi kwe-50/60Hz mains.
• Isilawuli sethu se-MFDC inverter DC siguqula i-3-phase AC ibe yi-DC, bese i-IGBT inversion inika amandla ku-welding transformer. Isebenza nge-1kHz inverter frequency enempendulo yokulungisa engu-1ms kuphela—ishesha ngokuphindwe ka-20 kunamayunithi avamile. Ukunemba okuphezulu kokulawula, impendulo esheshayo kanye nokukhishwa okuzinzile ngokwedlulele kuyaqinisekiswa.

2. Ukuzivumelanisa Negridi Yamandla

• Ama-welder e-Traditional AC spot asebenzisa i-single-phase 380V input, okubangela ukungalingani okukhulu kwe-3-phase, ukusetshenziswa kwegridi okuphansi, amandla aphezulu e-reactive kanye nokungcoliswa kwegridi nge-harmonics. Amayunithi amaningi adinga ama-transformer amakhulu futhi akhuphula izindleko zokutshala imali zekhasimende.
• Isilawuli se-IDW MFDC sisebenzisa i-balanced 3-phase 380V input nge-full-wave rectification, i-power factor ingaphezu kuka-90%, umsinga olinganiselayo kuwo wonke amaphase amathathu kanye nokuphazamiseka okuncane kwegridi.

3. Umshini Wokushisela & Ukonga Amandla

• I-AC yomugqa we-frequency ikhiqiza izikhala zokungena kwe-zero-current, ukushisa okuhlakazekile, ikhwalithi yokushisela engazinzile kanye nokulahlekelwa okukhulu ukushisa. Ukushintshashintsha kwe-voltage yegridi kubangela ukushintshashintsha okusobala kwamanje; i-inductance yesekethe yesibili iphazamisa kakhulu umsinga wokushisela.
• I-MFDC ikhiqiza i-DC eqhubekayo ngaphandle kokungena kwe-zero. Ukushisa kugxila endaweni yokushisela ukuze kuncishiswe ukulahlekelwa ukushisa futhi kufinyezwe isikhathi sokushisela ukuze konga amandla ngokuphawulekayo. Ukungabi khona kwe-AC peak current kunciphisa ukuchithwa kwe-spatter futhi kwandise impilo yokusebenza ye-electrode. I-inductance yesekethe yesibili ayithinti kakhulu umsinga wokushisela futhi iqeda ukulahlekelwa kwamandla esekethe.

4. I-Transformer Yokufanisa

• Ama-transformer emugqa wamandla angu-50/60Hz ayinkulu, asindayo futhi awasebenzi kahle ngaphansi kwesilinganiso samandla esifanayo.
• Ama-transformer afanisiwe anemvamisa ephakathi engu-1kHz anobukhulu obuncane, ukulahlekelwa okuphansi kanye nokusebenza kahle ukuze kufakwe kalula.

5. Ukuhambisana Okubanzi Kwezinto

• Ngaphezu kwamandla angenhla, izilawuli ze-MFDC zisekela amashejuli ahlukahlukene okushisela futhi zilingana nazo zonke izinsimbi: insimbi emboziwe, insimbi ye-galvanized, insimbi engagqwali, i-aluminium kanye nezinsimbi ezingafani, ezamukelwa kabanzi kuzo zonke izimboni zokucubungula izinsimbi.
• Izici Eziyinhloko Zesilawuli
• Imvamisa ye-inverter yokukhipha: 1kHz–4kHz, ukunemba kwesikhathi kwe-millisecond-level
• Igcina amaqembu afinyelela ku-32 amashejuli okushisela, anganwetshwa abe amaqembu angu-256
• Uhlelo lokushisisa olunezigaba ezi-3: ukushisisa kuqala, ukushisela, ukuthambisa; ukukhuphula/ukwehlisa kwamandla kagesi okwenziwa ngokwezifiso kanye nezibalo zomjikelezo wesigaba sokushisela
• Amachweba okukhipha okungenwayo angama-3 ahlelekayo, ahambisana ne-PLC, amarobhothi okushisela kanye nemigqa ezenzakalelayo
• Ukuxhumana kwe-RS485 ne-BCD code, kuxhunywa kwi-PC yezimboni ukuze kulawulwe kude futhi kuphathwe ngokuzenzakalelayo okuphakathi
• Ukuvalwa kwesekethe kwamanje kwesibili kwesikhathi sangempela, ukunemba kokulawula kwamanje kufika ku-5‰
• Umsebenzi wokurekhoda izexwayiso zomlando ukuze kutholakale amaphutha ngokushesha
• Ithebula Eligcwele Lezimpawu Zobuchwepheshe
