Yenza transformer yokubala

Uyilo transformer eqhelekileyo elula. It iqulathe i core yentsimbi, imibhijelo ezimbini ngocingo jiko. Enye coil kuthiwa yokuqala, yesibini - aphakamileyo. Imbonakalo AC ombane (U1) kwaye ngoku (I1) ngendlela lokuqala lale core yayo wampompoza ngemagnethi. Oku kudala EMF ngqo kwi coil zasesekondari, nto leyo incamathele umxokelelwane, kwaye unawo amandla amandla, lingana ne ukuya kwiqanda.

Ukuba elijikeleza ezidityanisiweyo kunye nokusetyenziswa kwenzeka, oko kukhokelela ekwandeni inxenye amandla ngoku Ikhoyili yokuqala. Le modeli yonxibelelwano phakathi engathi ucacisa inkqubo yotshintsho kunye nokunikezelwa amandla ombane, nto leyo ifakiwe ukubala abaguquli. Ekubeni onke nocingo Ikhoyili yesibini sinxulumene series, afunyenwe Iziphumo ezihlanganisiweyo le EMF eboniswe kwi iziphelo ifowuni.

Abaguquli ndawonye ukuze ukuhla kwamandla ombane kule coil yesibini maqhezu encinane (2 - 5%), nto leyo eyenza ukuba Kwingcingane ukulingana kwizibonakalisi yayo iphela U2 kunye EMF. Inani U2 liya kuba ngaphezulu / ngaphantsi kunjalo, inkulu kangakanani na umahluko phakathi kwenani amathuba ye jiko ezimbini - N2 kunye uN1.

Ubudlelwane phakathi nenani lamanqanaba ngocingo kuthiwa ratio yenguqu. Kuchazwa yi kwifomula (kwaye zibonakaliswe yileta K), ezizezi: K = N1 / N2 = U1 / U2 = I2 / I1. Amaxesha amaninzi lo mzobo ikhangeleka ngathi umlinganiselo integers ezimbini, umzekelo 1:45, nto leyo ibonisa ukuba inani amathuba yomnye jiko amaxesha 45 ngaphantsi koku enye imali. Lo myinge kunceda ukwenza ekubaleni transformer yangoku.

umphakathi Electrical ukuvelisa iintlobo ezimbini: ezimilise W-, nezikrweqe, ngobhobhozo magnetic branched zibe mbini, kunye U-imilo - akukho ngokwahlukana. Ukunciphisa ilahleko mhlawumbi kwentonga eyenziweyo ayikho ngokuqhubekayo, kodwa ubunjwe maleko ngamnye ezingcakacileyo zibe ngazodwa ukusuka kwenye nenye iphepha. Uhlobo zezindlu kakhulu rhoqo: isakhelo enyanzeliswa phezu primary jiko, ekhwele iibhola ngaphezulu kwephepha, kwaye phezu kwale maleko ezisisongezo koohola nxeba ucingo.

Ukubalwa nesiguquli kungabangela iingxaki ezithile, kodwa umyili-lover uya kuza kubanceda iifomyula lula enikwe ngasezantsi. Pre kuyimfuneko ukuba ukujonga amanqanaba ombane kunye nemikhosi zangoku ngayinye coil nganye. amandla Ukubala kwe ngamnye kubo: P2 = I2 * U2; P3 = I3 * U3; P4 = I4 * U4, apho P2, P3, P4 - amandla (W), engathi stackable; I2, I3, I4 - amandla ngoku (A); U2, U3, U4 - Voltage (V).

Ukuze ubone amandla iyonke (P) kubalo nesiguquli kufuneka ufake izalathisi sum engathi ngamnye, uze emva koko iphindwe ngumba we 1.25, nto leyo ethatha ingqalelo iilahleko: P = 1,25 (P2 + P3 + P4 + ...). Ke kaloku, P ixabiso uzakubala icandelo ezingundoqo umnqamlezo (in cm²): Q = 1.2 * kor.kv.P

Emva koko kulandela inkqubo yokumisela n0 inani amagophe 1 volt ngasinye ifomula: n0 = 50 / Q. Ngenxa yoko, ukufumana inani amathuba ye jiko. Kuba, kuthathelwa ingqalelo nokuhla kuqala ombane kule sombane, kuya kuba kulingana: N1 = 0,97 * n0 * U1
Kwabaseleyo: N2 = 1.3 * n0 * U2; N2 = 1.3 * n0 * U3 ... bepali nayiphi engathi ngumqhubi ibalwe ngokomgaqo wokubala: d = 0.7 * kor.kv.1 apho - umfutho yangoku (A), d - sangqa (mm).

Ukubalwa nesiguquli likuvumela ukuba ufumane i kul le sheathe lwamandla: I1 = P / U1. Kuhleli iipleyiti ubungakanani ayaziwa kwindawo core. Ukuze ufumane kuyimfuneko ukubala indawo kwemicimbi lwebhokisi engundoqo: SM = 4 (D1 (q) * + D2 N1 (q) * N2 + D3 (q) * N3 + ......), Apho SM - ndawo (mm square. ), zonke engathi kwi window; D1, D2, D3 kunye D4 - Ububanzi (mm); N1, N2, N3 N4 - inani amagophe. Ukusebenzisa le formula lichaza iindawo ezimagqagala jiko, ucingo ubushushu balo babulingana nesandla, isahlulo zihlala isakhelo mithambo ye window engundoqo. Ngokwexabiso ndasifumana ndawo kukhethiwe ubungakanani ipleyiti esikhethekileyo ukufakwa simahla lale window yayo. Okokugqibela, kubalulekile ukwazi - Ebubanzini iseti undoqo (b), nto leyo ifunyenwe kwi ifomula: b = (100 * Q) / a, apho kukho - ububanzi kwipleyiti eliphakathi (mm); Q - kwisikwere. Bona enzima yale nkqubo, -. Ukuze enze ekubaleni transformer (a element ibha yokukhangela kunye nobukhulu esifanelekileyo).
