Zamanje Ukwahlukaniswa. umshini Ukwahlukaniswa: izici, injongo

Ngokuqondisisa kulula umsinga umehluko okufanele ibhekwe njengelungelo inqubo ngokomzimba. Lapho kukhona touch ukushisa namakhaza Umqhubi endleleni, kungani kungekho umuntu abanjwe ugesi? Impendulo isobala: ngabodwa kuvimbela ukugeleza wamanje ngokusebenzisa umzimba womuntu. Kodwa uma umqhubi oluze, iqale i substrate ekuvikeleni bese uthinta wire? Umthelela kuyafana - akukho ukushaqeka kagesi. Substrate akusho ukukhiya wesifunda ngomzimba emhlabathini.

Umqondo zamanje umehluko

Emvelweni kukhona inqubo ngokomzimba ezifana umehluko zamanje. Lo mqondo eliningi vector, wezwakalisa njengoba isamba imisinga ekhona wesifunda, kuthathwe ngomqondo square kusho. Ukuze uvele umehluko zamanje, inqubo ngokomzimba ukwenzeka, ngokuthi ukuvuza zamanje. Kodwa kubalulekile ukuba kuhlangatshezwene nakho ngaphansi kombandela owodwa: isakhiwo imishini, lapho kwakukhona khona zamanje ukuvuza uxhumeke phansi. Uma kungenjalo, uma umzimba akuyona lusekelwe ke okuvela ukuvuza zamanje akakubangeli a wamanje umehluko. Futhi asalile zamanje wesifunda full (RCD) akusebenzi.

Ukuxhumana phakathi umehluko kanye zamanje ukuvuza

Lapho ukuvuza zamanje kwenzeka yesifunda, ke wabe izici kokuba okokusebenza conductive (metal housings for zikagesi, amapayipi kodwa angabangi umsindo, njll) Kusukela izingxenye ngaphansi voltage (izifunda kagesi, izintambo). Kulezi amasayithi esifushane ukuvuza akudingeki. Futhi ngakho akukho Iqiniso ukwephulwa ukusebenza wesifunda (sobala-ke lesion).

Kusukela lwamanje umehluko lapho express yayo izibalo limelela umehluko (Vector value) phakathi zamanje wamanje umthombo okukhipha futhi emva umthwalo, kuyaqondakala ukuthi kucishe zamanje ukuvuza. Kodwa uma yokugcina ukhona ngempela ukwephulwa, ezifana ukwahlukanisa, okusezingeni eliphezulu nomswakama imvelo, okuyothi lapho izophela, noma enye into, lamanje umehluko livela lapho maqondana nomhlaba.

Tripping futhi okungezona ezithothene umehluko imisinga

Ngaphansi ezithothene wamanje (noma ezithothene) ukufeza umehluko ukugeleza zamanje eliphumela a Ukuvuza Ukukhipha VDT lapha.

Ukugeleza zamanje okuyinto kwamukelekile wesifunda kudivayisi (RCD) kanye actuation yayo ingekho libizwa umehluko zamanje ze-non-ezithothene.

Isifunda ukulayishwa kuqashwa ishayela-uhlobo idivayisi: rectifiers, ngokuqhubekayo amadivayisi obuchwepheshe ukulawula amandla - wonke nemishini yesimanje, khona imisinga isizinda umehluko. Kodwa lezi imisinga akuzona imisinga umonakalo, futhi wesifunda kagesi kuleli cala ayikwazi inqanyuliwe. Ngakho-ke, i-RCD ezithothene embundwini kuyakhethwa ezifana hhayi okufanele sisabele ngayo lapho ukubaluleka yokusebenza ngemuva, futhi ukuvala wamanje ukuvuza esingeqile kwaleli nani.

RCD noma Machine umehluko

Ukuze uvikele circuit ngokumelene emhlabeni iphutha imisinga ubuningi emikhulu, ithuthukiswe ekhethekile wesifunda oluseduze. kudivayisi Ukushayela njalo ivivinya wesifunda elawulwa i ukuvuza kagesi. Uma isamba Vector komugqa imisinga amagugu kuyoba ngaphezu kuka-zero futhi engena umkhawulo ukuthola, masinyane vala wesifunda. izinhlelo ezinjalo asethwe futhi owodwa esigabeni futhi ezintathu okhombisa imigqa.

Izici umehluko ukushintshwa

ukulungiswa abahlukahlukene amadivayisi zokuzivikela ihluke nomunye ngoku:

• tesakhiwo;
• Kusho ukuvuza kukagesi;
• izilungiselelo lokutfutfukako;
• isivinini.

Kuye design izici yilezi:

• kudivayisi VDT (shintsha umehluko), lapho kungekho isivikelo imisinga okusezingeni eliphezulu. Indlela abasabela ngayo ukuvuza imisinga, kodwa ukuba abavikele icebo labo, njalo Udinga ukufaka fuses.
• RCBOs apharathasi lapho zinikelwa othomathikhi uhlobo inkinobho. Lezi amadivayisi jikelele nge umsebenzi ezimbili - ukuze ivikele short circuit futhi sindisa, kanye nokulawula ukuvuza.
• BDT kudivayisi nge kungenzeka iveni umshini endaweni uxhumano. Idivayisi Kuhloswe ukuba ukufakwa kanye full wesifunda. design Its wasebenza ngendlela yokuthi ivumela ukuxhumana yesikhathi esisodwa kumshini.

Kuye ukuma imisinga ukuvuza athuthukile amadivayisi iqembu zokuzivikela ezilandelayo ukulungiswa:

• AC - amadivaysi ezisebenza nge kushintshana zamanje sinusoidal. Abanaso aphendule Ukwahlukaniswa ishayela imisinga zako okwamanje lapho, isibonelo, Fluorescent, izibani-X-ray apharathasi, amadivayisi ekucubunguleni amasignali ulwazi, thyristor converters.
• A - amathuluzi ukuba asivikele ejabhile njalo futhi uhlelo lokwabelana ngamafayela. Awuyazi isiqongo ishayela umehluko ukuvuza imisinga. Zisebenza kagesi ezifana rectifiers, nabalawuli positionally ukuguqulwa. Vimbela emhlabeni ukuvuza kukagesi pulsed, okuyinto has a njalo voltage ingxenye.
• B - izinhlelo ukusebenza variable, njalo kanye ejabhile ukuvuza zamanje.

Ukuzwela umehluko inkinobho has lezi zinhlobo ezilandelayo:

• Okuphansi ukuzwela uhlelo ukuthi ukukhubaza wesifunda contact engesobala.
• Systems nge high-oda ukuzwela. Vikela, uma sekube ukuthintana ngqo siyinikeze umqhubi.
• Fire-elwa senzo.

Ngokusho isikhathi adingekayo ukusebenza kudivayisi:

• isinyathelo okuzenzekelayo.
• Speed okuphezulu.
• Ukuze inhloso jikelele.
• Ibambezelekile - uhlobo zikhethe.

zamanje Ukuvikelwa umehluko amadivaysi isikhethi Ungakhubaza kuphela ingxenye imishini, lapho sokwephulwa kwe iphutha.

Kanjani asalile zamanje wesifunda full

RCD sakhiwa core ngesimo indandatho nocingo ezimbili. Lezi Windings ziyefana, ukuthi wenziwe eyodwa ngocingo cross kwesigaba kanye nenani ematfuba ezifanayo. Ngemva eyodwa notshwala ikhoyili samanje isiqondiso okokufaka umthwalo, futhi eminye ngokusebenzisa ukubuyiselwa load yesibili emazombezombe. Njengoba umthwalo ngamunye sihamba wamanje wazikala imisinga kuthiwa wafingqa ngesikhathi input bese eMhlanganweni ekhishwa Kirgofu zilingane. Ngenxa yalokho, i-Imisinga Windings kudala yokucucuza efanayo kazibuthe iqondiswe kolunye uhlangothi. Lezi notshwala offset nomunye futhi uhlelo uhlala isimo esifanayo. Uma kuphela kwakukhona zamanje ukuvuza, amandla kazibuthe kuzohluka, izosebenza umehluko edluliselwe zamanje, okuzoba nomphumela kuvulwa oxhumana kagesi. Umugqa kagesi uzobe ngokuphelele uyeke nginomdlandla.

Lapho ukuphepha esebenzayo kudivayisi asalile zamanje

Ngo ukwakhiwa yesimanje kanye kagesi imishini ezindaweni, kanye zilungiswe amadivayisi ngaphezulu ukusetshenziswa ukuthi zamanje asalile. Lokhu ulungisiswa ukwanda ukuphepha nokusebenza amanethiwekhi kagesi, kanye ukwehla ukulimala. RCDs asetshenziswa:

• nezakhiwo zomphakathi: izikole, izakhiwo namasiko, izibhedlela, amahhotela, zemidlalo;
• izakhiwo kanye ngabanye efulethini yokuhlala: izindlu, Cottages, emahostela, izakhiwo ezihambisana;
• isikhala okudayisa, esenzelwe ngesisekelo metal izakhiwo;
• izakhiwo zokuqondisa;
• amabhizinisi ezimbonini.

ongakhetha Connection izikimu RCD

Ukwahlukaniswa kudivayisi zamanje zokuzivikela ukukhiqiza inombolo ezahlukene izigaba elibukhali. Kukhona owodwa isigaba, ezimbili-isigaba kanye ezintathu okhombisa asalile zamanje wesifunda oluseduze.

Uma umugqa isigaba esisodwa futhi kumele exhunywe kulo kanye RCD olulodwa wesifunda full, akwenzi mehluko isimiso, ufake ini kwasekuqaleni. Zonke lezi amadivaysi ezibekwe phezu okokufaka wesifunda. Vele kuwusizo kakhudlwana ukuba agqoke Esigabeni sokuqala othomathikhi bese asalile zamanje wesifunda full emva. Njengoba umthwalo ke axhunywe oxhumana rcd esikhundleni isigaba - emshinini, esikhundleni zero - kule divayisi Ukuvikelwa.

Uma umugqa oyinhloko ihlukaniswe imigqa eziningana imithwalo, le RCD kuqala, bese kuba ngenxa ulayini yephula wesifunda ngamunye. Kubalulekile ukuthi ukalwe zamanje ukuthi luyakwazi RCD, kwaba isikhathi eside umshini yokusebenza yamanje, ngaphandle kwalokho ngeke bakwazi ukuvikela kudivayisi uqobo.

isiphetho

Zonke umsebenzi inhlangano izintambo zikagesi kanye wesifunda Ukuvikelwa izinhlelo kungcono ishiyelwe a ngogesi okhokhelwayo! Nguwe kuphela bangahlangana ngezandla elula izifunda kagesi kanye yokuxhuma kumadivayisi ukuphepha, ngokuqinile landela imiyalelo. Ngokuvamile, umuntu ngamunye oxhumana naye has a ilebula okuhambisanayo.
