Ungakhetha kanjani isithando somlilo esincibilikayo sekhwalithi ephezulu?

1. Isekethe yokulungiswa kabusha kwesithando somlilo sokuncibilika kwe-induction iyisilungisi sebhuloho, esihlukaniswe izigaba ezintathu nezigaba eziyisithupha. Phakathi kwabo, isifunda sokuvuselela ibhuloho lesigaba sesithathu sakhiwe ngamaqembu amathathu e-thyristors, eyaziwa ngokuthi ukulungiswa kwama-pulse ayisithupha; isifunda sokuvuselela ibhuloho lesigaba esiyisithupha sakhiwe ngamaqembu ayisithupha ama-thyristors, aziwa kakhulu ngokuthi ukulungiswa kwe-pulse eyishumi nambili; ibuye isetshenziswe ezithandweni zokuncibilikisa zokungeniswa kwamandla aphezulu. Kukhona amashumi amabili nane okulungiswa kwe-pulse noma amashumi amane nesishiyagalombili ukulungiswa kwe-pulse.

Umgomo wokusebenza wesekethe yokulungisa ye ukuchithwa kwesithando somlilo ukuhlela i-thyristor ehambisanayo ukuthi ivulwe futhi ivalwe ngesikhathi esifanele ngokomthetho othile, futhi ekugcineni uqaphele ukuguqulwa kwamandla ashintshayo wezigaba ezintathu abe wamanje oqondile.

2. Isekhethi ye-inverter yesithando somlilo esincibilikisa i-induction iwukuguqula amandla akhona aqondile alungisiwe abe amandla aphezulu ashintshashintshayo ukuze anikeze umthwalo wekhoyili, ngakho-ke le inverter yokuncibilika kwesithando somlilo empeleni iyinqubo ye-“AC-DC-AC”.

Isifunda se-inverter yesithando somlilo sokuncibilika se-induction sihlukaniswe isithando somlilo esihambisanayo ne-resonance inverter yochungechunge. I-parallel resonant inverter circuit isetshenziswa kabanzi, futhi cishe zonke izithando zokuncibilika zakuqala zisebenzisa lesi sijikelezo sokulawula, esivuthiwe. Okubi ukuthi isici samandla sikhuphuka ngokunyuka kweshaja, futhi isici samandla esijwayelekile singaba ngu-0.9; I-series inverter induction melting isithando somlilo sivele eminyakeni eyishumi edlule, futhi inzuzo ukuthi isici samandla siphezulu, ngokuvamile ngaphezu kuka-0.95, singakwazi ukubona imizimba emibili yomlilo isebenza ngesikhathi esisodwa, ngakho-ke ibizwa ngokuthi ukuncibilika okukodwa kokubili. isithando somlilo embonini ye-Foundry.

3. Okokuhlunga kwe- ukuchithwa kwesithando somlilo, ngenxa yokuguquguquka okukhulu kwe-voltage elungisiwe, kuyadingeka ukuxhuma i-inductor enkulu ochungechungeni lwesekethe ukwenza yamanje bushelelezi, okungenza i-voltage ngokuguquguquka okukhulu kube bushelelezi. Lokhu kubizwa ngokuhlunga. Le inductance ngokuvamile ibizwa ngokuthi i-reactor. Isici se-reactor ukugcina umsinga ekushintsheni okungazelelwe.

Isithando somlilo esincibilikayo se-induction sinikezwa kumjikelezo we-inverter ngamandla abushelelezi e-DC ngemva kokuhlunga. Amadivayisi ochungechunge ahlungwa ngama-capacitor ukuze athole i-voltage ebushelelezi.
