DC eliminator: imigaqo kunye nomda ukuguquka

Kuye into kwengxoxo edlulileyo phakathi AC ne DC elide. Ngemihla okuqala kombane umbane kwemiba zothutho ziye kuxoxwe nzulu. I wonder xa ndijonga indlela iziphaluka elektroniki, ukuba kukho ukungaqondani njalo kwezisekelo? Kodwa abaxhasi i-AC waphumelela, kwaye ukuguqula ngoku kuyimfuneko ukusebenzisa nezikmu ezininzi nezahlukeneyo. Abaninzi kubo baye yakudala ezisetyenziswa kakhulu kuyilo izixhobo ezahlukeneyo.

Enye iintsika zombane kunye ngombane yi DC rectifier. Zuza ekusebenziseni kwayo ayikwazi babebiza imali, i-DC ombane ukuze igunya phantse zonke izixhobo. Loo ukutya kuyimfuneko ukulungiselela eqhelekileyo kwisixhobo. Lisetyenziswa kwi kwimveliso.

scheme uqhagamshelo diode Classical ecetywayo yi Hertz ngexesha elililo, kukade icangcisiwe, elingasetyenziswanga. Kuyenzeka ukufumana incazelo enengqondo, wasebenzisa diode ezine ekulungiseni le ombane AC waba ukuyilahla ubuncinane. Nangona iimpawu semiconductors ziye kancinane wafunda, yaye kwimibhobho ongenawo babebiza kakhulu. Rectifier DC wakhangela ezahlukeneyo, kunye neempawu zawo zimbi.

Le meko kakhulu nokufika izixhobo semiconductor. Kwakukho iziphaluka ezahlukeneyo rectifier, ngamnye enobuhle kunye neengxaki. Kodwa Hertz scheme DC-based nangoku umthombo inokuthenjwa. Ububi le ibandakanya imilinganiso yalo lulonke kunye nokusebenza ephantsi. Kukholelwa ukuba imithombo ezinjalo ndawonye kwi indlela ekuthiwa-yomgama.

A umfanekiso ezahlukeneyo ngokupheleleyo uyaqapheleka izixhobo rectifier buthathwa kwisiphaluka non-linear. Kakhulu yimpumelelo, njengoko kubonisiwe, baba isenza izinto ngamandla. Bona, ndayihluthwa zonke ezingalunganga yesixhobo yomgama ekulungiseni, kodwa ube kwinqanaba eliphezulu kwimveliso nengxolo ngaphantsi nokuthembeka. Ezinjalo DC rectifier ngokufuthi kuqhekeze, ekubeni imveliso yazo lu dityanisiwe inani elikhulu leziqalelo ezisetyenziswayo.

Ezinamandla di- semiconductor, bahlanganisana ibhulorho diode, ingasetyenziswa ukuqokelela iwelding rectifier DC. Loo isixhobo kulula ukwenza ngezandla zakho. Ama 250 Amp nangaphezulu zifakwe kwi isinki ubushushu. Bona ekhwele kwisiseko engqongqo textolite. izixhobo Cathodes ezidityaniswe kunye, oku kuya kuba plus. Anodes nabo idityaniswe nge copper kunye, kuya kuba isixhobo thabatha. pair ezimbini lobuceducedu. Iziphelo isibini ngasinye nazo adityanisiweyo Shinko nobhedu, zibalwa ithombo ezinkulu iwelding yangoku. ke esidla kunye ifildi ombane le transformer welding. Wena obuziqokelele isixhobo ekwaziyo yokulayisha ifayile enkulu ibe current ngqo. Rectifier ukuba umatshini welding esetyenziswa kule nkqubo, ngokwaneleyo robust ukuqinisekisa ixesha yokusebenza elide lonke icebo.
