Isigaba voltage

Eside siqine ezimpilweni zethu amagama kagesi kusukela ucwaningo lokuqala ngogesi. Kodwa manje, ngandlela-thile, ngisho abe ukuphela efile, ucabanga ngesikhathi lapho, njengoba besho, "Lutho." Akekho ayikwazanga khanyisa, isibonelo, okungukuthi voltage isigaba, ngoba lelo gama wayengekho. Kodwa konke kwemali, konke izinguquko, futhi manje nedlanzana izinguqulo ezimbili ezahlukene ukucindezeleka akumangalisi muntu. Isicelo wokuqala voltage ezintathu okhombisa, lapho zonke izinto zahamba, engxenyeni kwekhulu le-19 yesibili. Konke lokhu kwaqala lapho utadisha lo mkhuba lokungeniswa kagesi. Ingqikithi ukuhlola olandelayo kwaba elula - is badabula ikhoyili kagesi , futhi uheha induku yensimbi. Okuningi - ngaphezulu. Uma eceleni komunye ikhoyili, vala yamanje ithuba lokuqala nelesibili - induku ikhangwa futhi, kodwa ikhoyili yesibili. Izimangaliso! Rod wathutha emkhathini kuphela esebenzisa yanjalo isicelo wamanje lekhoyili! Yilokho lula kangaka futhi, njengoba besho, ngaphandle kokushiya Igumbi, ngalezo zinsuku benziwa okutholakele esaqopha umlando.

Uma uqhubeka ulinge, ngisho noma ngokwengqondo, ukubeka ohlobo 100 awaphendule zihlanganisa, cima, kungabonwa ukuthi induku liyasuswa ngowokuqala zokugcina. Ikhoyili ilungiselelo ukucushwa ushintsho - ngeke uwafake embuthanweni, kodwa esikhundleni induku inamathela eyodwa umcibisholo ku-eksisi circle phakathi. Futhi, ku-off izikhathi 100: umcibisholo waphenduka wathatha isikhundla ukuqala. Yini sifika? Sathola imodeli bakudala we ujikelezisa kazibuthe. Ngenxa yale njongo, ikhoyili ishayela ngamunye voltage lasetshenziswa ngesikhathi ( "ku-off"). Kubalulekile kakhulu ukuthi i-pulse olandelayo fed isikhathi ngikusenza maqondana amplitude odlule futhi yamanje ahluka zero kuya seqiwe - ku, futhi futhi zero - ivaliwe. Ngomqondo onabile, inkulumo inqubo nokuwa samanje ikhoyili ngamunye kwaba okufanayo. Le nqubo iterative kwabantwana okuthiwa ukubanika isikhathi-eyindilinga, nesikhathi komunye isiqongo elandelayo - umjikelezo.

Uma, ngesikhathi umjikelezo we samanje ikhoyili kushintsha yobukhulu nokusakazeka isiqondiso, ibizwa ngokuthi kwenombolo. Voltage AC has nemingcele ezilandelayo: amplitude - esiphezulu wamanje noma voltage imvamisa - isibalo oscillations ngomzuzwana. Ukubuyela ekuhlolweni ngenhla ohlobo, uqaphele ukuthi ngamunye wabo ifakiwe ngokuhlukile kwezinye (kusuka lwaluvelaphi voltage) kanye voltage supply imijikelezo kwahluka kuphela ukufakwa isikhathi noma, njengoba ugesi, isigaba. Ngakho, umehluko voltage kuphela ukuthi unesikhathi ezahlukene ukushintsha samanje ikhoyili kumbe voltage isigaba ezahlukene. ngqó, impendulo ingu esigabeni - kuyinto yinye igama elithi "ukulibala". It nanela ukuthi igama elithi "Isigaba voltage" sibhekisela kuphela ohlelweni multiconductor lapho umthombo wamandla nomunye ekupheleni exhunywe kwi iphuzu ovamile, nemikhawulo yomhlaba yesibili ngamunye wabo uxhumeke kwi-coil. Kwenzeka isimanga ngokomlando ukuthi babashayeli supply zibizwa futhi ngokuthi izigaba. Le nqubo uhlelo esetshenziswa kakhulu wathola nge voltage sinusoidal bese bakha shift isigaba 120 °, isb Isikhathi ingenye nantathu imvamisa yokusebenza kwesikhathi. The main umphumela yomsebenzi izinhlelo ezintathu okhombisa - ukuthola ujikelezisa kazibuthe.

Ukuze uqhathanise, izici amandla izinhlobo ezahlukene voltage ngokuthi kukhulunywa voltage ukwamukela DC. Ukuze sithole okulingana AC voltage njalo, uqhubeke ngendlela elandelayo: imithombo ehlukene ukucindezeleka ukulayishwa abathengi ezifanayo futhi ukulungiswa we ngabodwa ukucindezeleka sifinyelele esilinganayo amandla kuzo zombili imithwalo. Empirically wafakazela ukuthi isigaba voltage lapho kukhululwa amandla e umthwalo efanayo ne standard, has a ubukhulu izikhathi 1.42 DC. Ngo umkhuba, ukubaluleka voltage ekhombisa kudivayisi, futhi ubizwa esebenzayo AC voltage.

Ekuphileni kwethu kwansuku zonke sisebenzisa ezintathu okhombisa amandla zezimboni amanethiwekhi, lapho uthi "volts 3 kuya 380." Ngo amanethiwekhi enjalo, isigaba voltage kuyinto 220V, futhi isiqongo inani layo - 308B.
