Voltage line kumanethiwekhi kagesi

Ungahlala batholakala kulo lonke legatsha ubunjiniyela uhlobo echo bezikhathi zasendulo, okungukuthi isihloko, khomba uhlobo umlando ukuthuthukiswa kulesi siqondiso. Futhi bambalwa bayazi ukuthi omunye umqondo lobuchwepheshe has ibanga elide ukuze abe, umlutha, futhi ekuqaleni kosuku lokuzalwa kwakhe owamenyezelwa omunye, ngokuvamile eningi kakhulu, zobuchwepheshe isinyathelo kuyaqhubeka. Ngakho, ngokwesibonelo, kuvamile impela ukuzwa inkulumo ethi "ezintathu okhombisa voltage" phakathi imigomo kagesi "umugqa voltage", "unomphela" noma "AC voltage" nezinye amagama amaningi ngegama elithi "ukucindezeleka".

Ekuqaleni, njengoba ngokomzimba value voltage kuchazwa njengoba umehluko nekhono emkhakheni kagesi ukuthi ongenza umsebenzi ukuhamba icala kagesi kusuka kwelinye iphuzu eya kwelinye ensimini. Ophathwa ukufuduka ensimini amandla edliwe, Nokho, inani layo, noma ngaphezulu ngokunembile, umehluko ezingaba kuyehla kube zero. Ngo langempela circuit avaliwe ukunyakaza amacala kagesi iphathwa njengenhlangano zamanje kagesi - umphumela ukunyakaza electron kusuka kwelinye iphuzu eya kwelinye chain. Ukuthi akakashintshi, kubalulekile ukuba silondoloze njalo voltage umehluko. Njengoba yaziwa, ukugcinwa samanje wesifunda "uyazi" amandla supply. Kusukela ke sibone ukuthi wamanje yesifunda kuyoba njalo, okusho ukuthi, ayishintshi ezidlula yayo futhi isiqondiso, noma variable, ukushintsha ngokusho kwabanye umthetho. Igama elithi "umugqa voltage" kunengqondo kuphela amanethiwekhi kushintshana zamanje.

I kabanzi kunazo lisetshenziswe Ihluzo Elingafaki Ukuqoka wathola AC voltage wave sine. Umkhawulo voltage ukubaluleka lapho ebizwa oscillation amplitude Ua. Ukuze uthole voltage enjalo isebenza iyunithi eyengeziwe - F imvamisa kanye ψ isigaba. Imvamisa kunqunywa inani oscillations per unit isikhathi, futhi isigaba - yisikhathi offset ezifanayo amaphuzu vibration. Ngakho Ngokomlando, elithi "Isigaba" sabizwa ngokuthi, futhi amandla umugqa AC voltage, uma iyingxenye simiso izigaba eziningi - imvamisa emalunga lamatsatfu. Ezintathu okhombisa inethiwekhi kwaba enye impumelelo engineering kagesi kanye kunezimo eziningi ukuze akunakwenzeka ukuba kudlule. Futhi ebaluleke kakhulu kubo - leli yithuba elula kakhulu, eqinisweni, singenzi lutho ukuthola ujikelezisa kazibuthe - isimiso eziyisisekelo nokuqhutshwa motor. I wesifunda ezintathu okhombisa ukuhlukanisa phakathi isigaba kanye isigaba voltage, futhi sici yayo itholakala ukuthi ngamunye izigaba is offset mayelana nezinye degrees ezimbili +/- 120. I generator isigaba voltage kuyinto okukhipha Windings, lapho ikhipha esibekiwe Isigaba shift. Ngamunye the Windings inomkhawulo kanye ekuqaleni: u-N1-K1, K2, H2, H3, k3. Esimisweni ezintathu okhombisa, kukhona ezimbili amathuba isigaba uxhumano - "inkanyezi" futhi "delta".

Uma uxhuma kunoma "inkanyezi" yonke imikhawulo axhunyiwe komunye iphuzu - "isiphelo 0" futhi uqale ukukhonza imikhawulo esibulalayo generator kanye kwidivaysi yokufakwayo for the wabanika amandla. Ngo isimiso esinjalo, voltage line - ukubaluleka kulinganiswa phakathi iyiphi pair of okukhipha semikhawulweni H1, H2, H3, futhi selisho Ulin. Kukhona esinye futhi isici we ezintathu okhombisa - isigaba voltage. It luchazwa UF walinganisa phakathi kwezindawo "0 okukhipha", futhi yimiphi esidayisa uphela K1, K2 futhi k3. Yeqa imininingwane, kufanele kuphawulwe ukuthi, ngokusekelwe umdwebo phasor inethiwekhi ezintathu okhombisa, ubuhlobo phakathi kwalezi voltages Ulin = Ѵ3 * UF. Lapho oxhumanisa "unxantathu" semikhawulweni Windings axhunyiwe e indandatho: K1-H1-H2-K2-k3-K1-H3. Ngamunye kwakwakhe 'ukuphela - ukuqala "kuyinto okukhipha, futhi lapho voltage line lihlukile isigaba, okungukuthi, Ulin = UF. Kuyathakazelisa ukuqhathanisa phakathi zinamandla njalo Udir kanye amplitude kushintshana voltage Ua, isib, ngokusekelwe amandla efanayo ekhiqizwa kuleli umthwalo. Ukuze Kulokhu Udir = Ѵ2 * Ua.

Yilokho ngoba emashumini kuye efaka ulwazi mayelana nemvelo kanye nesimo ugesi, kanye nomqondo buthule okulula "ukucindezeleka" usezuze ngokwemibandela ahlobene, sithuthukisa ikhono lethu ukusebenzisa imvelo ukuze kufezwe izidingo zabantu.
