Ukuqapha voltage udlulisela - idivayisi iphinde Umgomo we operation

Kaningi, amakhaya ngisho yesimanje nezindawo zokuhlala voltage ezifundeni kagesi namanethiwekhi kungaba ukugibela ibanga kunalokho enkulu. Yiqiniso, lezi izinhlanga abe nomthelela omubi umsebenzi ekhaya Imishini ukuqina yayo. Ukuvimbela lezi zimo, usebenzisa isilawuli voltage udlulisela. Isizathu ka yokwanda kwama enjalo kungaba zokugwema ukuphuka wire noma nokuwohloka, ukuze isigaba wire ngokuphathelene no-zero. Kungakapheli imizuzwana embalwa, ngisho nangaphambi kokuba isivikelo esiyoba, ungafaka amakhompyutha, amafriji, nemisakazo kanye nezinye zikagesi zasendlini.

Kuyini voltage control edluliselwe? Le divayisi multi-pin (phakathi ezimbili futhi ezine izigxobo), leyentelwe ujike ngokuzenzakalelayo futhi uvule zikagesi ezahlukene kagesi (heater, amafriji, umsakazo, njll). Ukuze ukuzilawula ngokuzenzekelayo ukulawula voltage edluliselwe ukusetshenziswa microprocessors zahlelwa ngokukhethekile microcontrollers ukuthi kokubili izinzwa lokushisa, zamanje, voltage, undervoltage, futhi banesibopho zedivayisi ngokwayo phansi inqubo ngenkathi off.

Kumele sicacise ukuthi by design nemibandela ukusetshenziswa, kuye ngokuthi isibalo izigaba, ukuhlukanisa udlulisela ukulawula ezintathu okhombisa nasezakhini isigaba voltage. Ezintathu okhombisa kudivayisi Ukuvikelwa kagesi ngokumelene overloads okuseqophelweni kungenzeka subsidence uma iphutha ukujikeleza isigaba, izinyathelo amagugu ephumelelayo isigaba futhi umugqa voltages kumanethiwekhi kagesi nge ilahliwe noma earthed hlangothi, ilawula usuke iyunithi ugesi wesifunda umthwalo (ikakhulukazi ikhoyili we actuator kazibuthe). Njengoba ezintathu okhombisa ukulawula voltage udlulisela nedivayisi owodwa esigabeni engamele amandla oxhumana ukuziqalela kazibuthe noma contactor, kokubili ngaphambi nangemva ukhanyisa futhi ukushintsha umthwalo, ukulawula isimo ukuseviswa kanye operability lezi oxhumana nabo. Idivayisi sivaliwe uma esivuthayo noma ababambelela oxhumana. Udlulisela lokulawula voltage inganikwa amandla nge isikhathi ezichazwe umsebenzisi ekhethekile emva inkinga.

Isebenza edluliselwe ulula. Sebenzisa izindlu Kufanele usethe imibundu (esiphezulu kanye esincane) namagugu voltages at okuzokwenza razryvatsya chain. Amanani Standard - kuba 170 V kanye 240 V. Le edluliselwe okuzenzakalelayo usebenza 0.02 imizuzwana. Lokhu ijubane eliphezulu kakhulu off voltage ngaphambi kokuthi umxhwele imishini kanye nemishini. Nokho, udlulisela ukuqapha voltage musa ukuvikela iziteleka umbani.

Zimbili izinhlobo udlulisela ezifana: eyodwa uphuma khona, futhi indlu ngokuvamile. I last ezivamile. Amadivayisi kuhluke umthwalo futhi wamanje kuvunyelwe.

Uma ukhetha nokufaka ezimele ukulawula voltage udlulisela kufanele siqaphelisise imiyalelo yokufaka. Ngokwengxenye enkulu, okufanayo wiring imidvwebo, Nokho, kuye ngokuthi umenzi, eminye imininingwane ingehluka.
