Abaguquli yizakhi ezibalulekile ezinhlelweni zikagesi, zidlala indima ebalulekile ekudluliseleni nasekusatshalalisweni kwamandla. Beza ezinhlotsheni ezahlukahlukene, kufaka phakathi abaguquli bemvamisa ephansi kanye nabaguquki bemvamisa ephakeme, ngalinye liklanyelwe ukusebenza ngaphakathi kwamabanga athile avamisile. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zabaguquli kubalulekile kunoma ngubani osebenza nezinhlelo zikagesi. Kulesi sihloko, sizohlola ukuthi yimaphi ama-transformers aphansi aphansi, anciphise umehluko phakathi kokuvama okuphezulu kanye nabaguquli abaphansi, bese nixoxa ngezicelo zabo.
Yini i-transformer ephansi yemvamisa?
I-Transformer ephansi yemvamisa uhlobo lomguquki kagesi oklanyelwe ukusebenza kumafrikhwensi ngokujwayelekile ngaphansi kuka-500 Hz. Lawa ma-transformers asetshenziswa kakhulu ezinhlelweni zokusabalalisa kwamandla, izinhlelo zezimboni, kanye namadivayisi ahlukahlukene kagesi. Zenzelwe ukuphatha amazinga aphezulu amandla futhi zivame ukuba zikhulu futhi zisinda kakhulu uma kuqhathaniswa nabaguquli abaphezulu bemvamisa. Ama-transformers aphansi aphansi ayaziwa ngekhono lawo lokudlulisela amandla kagesi ngempumelelo kusuka kumjikelezo owodwa kwelinye, ngokulahleka kwamandla okuncane.
Umehluko phakathi kokuguqulwa imvamisa ephezulu kanye ne-transformer ephansi yemvamisa
Umehluko oyinhloko phakathi kwama-transformers aphezulu aphezulu kanye nabaguquli abaphansi bemvamisa balele ebangeni lemvamisa lapho basebenza khona. Abaguqukayo abaphezulu kakhulu be-transformers benzelwe ukusebenza emafrikhwe ngenhla kwe-500 Hz, imvamisa ifinyelela ku-kilohertz noma ibanga le-megahertz. Ngokuphambene nalokho, abaguquli bemvamisa ephansi basebenza emafrikhwensi ngaphansi kwama-500 hz. Lo mehluko ebangeni lemvamisa kuholela ezicini eziningana ezihlukile kanye nezicelo zohlobo ngalunye lwe-transformer.
Enye yokwehluka okusemqoka phakathi imvamisa ephezulu kanye nama-transformers aphansi aphansi ngosayizi wawo nesisindo sawo. Ama-transformers aphezulu wemvamisa amancane ancanyana futhi alula kunama-transformers aphansi aphansi, abenze balungele izinhlelo zokusebenza lapho isikhala nesisindo ziyizinto ezibucayi. Ngokwengeziwe,I-High Frequency TransformersBayaziwa ngekhono labo lokuhlinzeka ngokuguqulwa kwamandla okusebenzayo kumadivayisi we-elekthronikhi afana nabakwa-Inverters, izinsiza zamandla wemodi yokushintsha, kanye nezicelo zemvamisa yomsakazo.
Ngakolunye uhlangothi ama-transformers aphansi, ngakolunye uhlangothi, aklanyelwe ukusetshenziswa kwamandla aphezulu lapho ukusebenza kahle kanye nokwethembeka kubaluleke kakhulu. Lawa ma-transformers asetshenziswa kakhulu ezinhlelweni zokusabalalisa kwamandla, imishini yezimboni, kanye nemishini kagesi esindayo. Ubukhulu babo obukhulu bubavumela ukuba basingathe amazinga aphezulu bamandla ngenkathi benciphisa ukulahleka kwamandla, okwenza balungele izinhlelo zokusebenza lapho ikhwalithi yamandla nokuthembeka kubaluleke kakhulu.
Omunye umehluko obalulekile phakathi imvamisa ephezulu kanye nabaguquli abaphansi bemvamisa yizinto zabo zokwakha nokwakha. Ama-transformers afinyelela amaza aphezulu avame ukusebenzisa ama-Ferrite cores noma ezinye izinto eziphakeme zokufezekisa ukufezekisa ukusebenza okusebenzayo kumafrikhwensi aphezulu. Ngokuphambene nalokho, abaguquli bemvamisa ephansi bavame ukusebenzisa ama-cores ensimbi alenga ukubhekana namazinga aphezulu kazibuthe ahlotshaniswa namafrikhwensi aphansi. Lo mehluko wezinto zokwakha okuyisisekelo nokwakhiwa kukhombisa izidingo eziyingqayizivele zohlobo ngalunye lwe-transformer ngokususelwa ebangeni lakubo elisebenzayo.
Izicelo zama-transformers aphansi aphansi kanye nabaguquli abaphezulu bemvamisa
Ama-transformers aphansi aphansi athola ukusetshenziswa okubanzi ezinhlelweni zokusabalalisa kwamandla, ukufakwa kukagesi, imishini yezimboni, nemishini kagesi esindayo. Amandla abo okuphatha amazinga aphezulu aphezulu futhi anciphise ukulahleka kwamandla kubenza babe yizingxenye ezibalulekile ekuqinisekiseni ukuhanjiswa kwamandla okuthembekile nokusatshalaliswa. Ngokwengeziwe, abaguquli bemvamisa ephansi basetshenziswa ezinhlelweni ezahlukahlukene zezimboni ezinjengemishini yokushayisana, ukushayela kwezimoto, kanye nokuhlinzekwa kwamandla ngemishini esindayo.
Abaguqukayo Abaphezulu Bemvamisazivame ukuqashwa kumadivayisi we-elekthronikhi nezinhlelo lapho ukuguqulwa kwamandla okusebenzayo kanye nosayizi ohlangene kubalulekile. Zisetshenziswa kabanzi ku-switch-Mode Power Supplies, imishini yokuxhumana ngocingo, ama-amplifiers audio, kanye nezinhlelo zokusebenza zemvamisa yomsakazo. Ubukhulu obuhlangene kanye nokusebenza okuphezulu kwama-transformer aphezulu wemvamisa kubenza balungele amadivaysi anamuhla kagesi adinga ukuguqulwa kwamandla okuthembekile esikhaleni esilinganiselwe.
Ekuphetheni, umehluko phakathi kwama-transformers aphezulu wemvamisa kanye nama-transformers aphansi aphansi agxile ebangeni lawo lokusebenza, usayizi, ukwakhiwa kanye nezicelo. Ngenkathi ama-transformers aphezulu efinyelela kufinyelela ekuguqukeni kwamandla kagesi kanye nosayizi ohlanganisiwe wamadivayisi we-elekthronikhi, abaguquli abaphansi abaphansi babalulekile ekuphatheni amazinga aphezulu amandla kanye nokuvikela ukuhanjiswa kwamandla okuthembekile. Ukuqonda izici ezihlukile kanye nokusetshenziswa kohlobo ngalunye lwe-transformer kubalulekile ukuklama nokusebenzisa amasistimu kagesi asebenzayo futhi athembekile.
