Transformer A si fiican u yaqaan tallaabo-up ...

aagga kasta wuxuu leeyahay technology qalab taariikhi ah u gaar ah, kaas oo eegaya hubaal ogaan waxa, halkaas oo, sida. Dhoofnay - waa badda, yachts, maraakiibta. Rafaasad - duulista, diyaaradaha, wheel - baaskiil, gaariga, iwm Oo annaguna waxaannu mar walba ma ka tarjumaya xaqiiqda ah in mar kuwan qalabka hadda fudud oo cad sida soo socota ahaayeen, tallaabo mararka qaarkood way adag tahay in horumarinta laanta dhan of injineernimada ama injineernimada farsamada.

taariikhda noocan oo kale ah oo wakiil ka ah si fiican u yaqaan of injineernimada korontada - transformer. In hore u fog 1831 Faraday galay taariikhda helitaanka induction electromagnetic - aasaasiga ah mabda 'hawlgalka of transformer ah. Kaliya 45 sano ka dib, saynisyahan Ruush PN Yablochkov la siiyey patent ah la alifay ee transformer ah. Labada gariiradda ku yaalaan on xudunta u furan, ayaa xaqiijiyay in suurtagalnimada inay u beddesho, in uu yahay, badalo, ka beddeli hadda iyo voltages. The transformer ugu horeysay waxaa laga dhigay ilaa. gudbiyeyaasha Modern leeyihiin dhinacyada dhismaha dhowr dabaq in sheyga yar waa in ka yar 1 cm, iyo wax soo saarka - waa laan ugu horeeysa ee warshadaha korontada.

Farsamada waxaa loo isticmaalaa tiro badan oo gudbiyeyaasha ujeedooyin kala duwan oo mid waliba ay leedahay magac gaar ah u gaar ah. Tusaale ahaan, isticmaalka baahsan ee korontada ayaa tallaabo-up a transformer danab, taas oo ah at danab saarka dhowr kilovolts waa danab sahayda of 220 V. ah

Sayidka, transformer ah - waa maxay? Qeexidda classic waa sida soo socota: transformer - waa mishiinka korontada in badasha talooyin loogu fuuli jiray la danab a kala duwan il awoodeed oo galay dugsiga sare ee hadda ka. transformer wuxuu ku shaqeeyaa iyadoo danab AC ah, maxaa yeelay, saamayn induction la arko marka kaliya ee beerta electromagnetic. kala iibsiga (Isbadal) ee tamarta maraa beddelidda ee tamarta korontada ee windings ee duurka ugu horeysay magnetic, iyo dheeraad ah - kala guurka ah dib ugu tamarta korontada hadda, laakiin in sare loogu fuuli jiray. Haddii dugsiga sare on tirada markooda fuuli ka badan aasaasiga ah, waxaan leenahay transformer tallaabo-up a, iyo haddii aad ku xidhi windings on lid ku ah, transformer uu noqon doono "horjeeda" - dhimista.

Ka soo qaad in aad u baahan tahay in garaashka, taas oo uu leeyahay oo ah urur 36V korontada, ku xidha xamuulka korontada, sida ku amraya akkamuljatora unit ku shaqeeya 220 - kiis caadiga ah si aad u dalbato transformer tallaabo-up a. Xalka dhibaatada this, waxaanu ka fiirsan tallaabooyinka wax ku ool ah.

1. Power xeedho doonaa baasaboorka - u badan tahay waxa ay noqon doontaa wax u eg 100 watts. Ogaaday in had iyo jeer u baahan tahay in margin ah mustaqbalka iyo in view of tayada mustaqbalka ee transformer ee ku saabsan 0.9, awood u helay 150W ku fuuli jiray aasaasiga ah.

2. Dooro harqoodka. Waa ay fududahay in la xakameeyo xudunta O-qaabeeya magnetic (TV jir). Waxaan isticmaali kartaa wax kasta, kuwaas oo qaybta cross waa ka yar yahay ka xiriirka saadaaliyay: P 1 = S * S / 1,44, halkaas oo P1 iyo S - awood transformer ee watts iyo core cross-qaybta in square cm. Xisaabinta qiimaha siinayaa ah S = 10,2 cm2.

3. Tallaabada xigta waa waxa ugu muhiimsan ee "dhismaha" of transformer ah - waxaa lagu go'aamiyaa tirada markooda 1B: N = 50 / S = 50 / 10.2 = 4.9 markooda / ku. Hadda waa ay fududahay in xisaabiso tirada markooda (ama, sida "fuuli jiray macluumaadka"), windings hoose iyo sare: W1 = 36 * N = 176 markooda iyo W2 = 220 * 5 = 1078 markooda.

4. Qeex hadda loogu fuuli jiray. Waxaan qaadaneynaa in xoogga kasta oo ka mid ah windings ee ku saabsan 150 watts. Xaaladdan oo kale, ka hawlgala windings hadda: J1 = 150/36 = 4,2A iyo J2 = 150/220 = 0,7A.

5. Hadda waxaad haysataa dhammaan xogta si ay u ogaadaan dhexroor ah oo silig of windings ah. Waxaan sidaas ku samayn doonaa, waayo, D1 ku gariiradda hoose = 0,8 * √J1 = 0,8 * 2,05 = 1,64mm sq. ;

Sidoo kale, waayo, D2 sare loogu fuuli jiray = 0,8 * √J2 = 0,8 * 0,84 = 0,67 mm square.

Fuuli jiray gariiradda dhexroor xulo soo socda ka caadiga ah.

Wax kasta! Xisaabinta waa in ka badan, laakiin soo saari kartaa transformer tallaabo-up a gacmahooda? Sida ay iyagu yidhaahdaan - ma jirto wax fudud, haddii si xun loo baahan yahay. Baahida loo qabo dhabta ah - waa DIY ugu weyn ee ciidamada driving, si ay gacanta dheeraad ah, ka qabtaa.

6. Samee laba baqtigooda on a circuit magnetic soo xulay.

Sargaal Sare 7. loox cufan la duubo kala badh aasaasiga ah loogu fuuli jiray iyo go'doomiyo waxaa quraarado ama la dahaadhey.

8. Next, Mire Waqaf oo ku saabsan loox kasta by badh sare loogu fuuli jiray iyo sidoo kale dabooli dahaadhey ah.

9. shirka The Bannaanka magnetic, qaybo harqood coupler - Dhibaatadu ma aha mid aad u adag. In ururinayo ka toortaha core magnetic waa la jecel yahay in ay u ogolow in Halabuurka kasta oo isticmaalaya ferroporoshka - this saaro doonaa "guuxayaan" qalab inta lagu jiro hawlgalka.

Taasi waa! Our guriga-dhigay, annagu kala ma qabaa shaqayn doona muddo dheer iyo farxad. Oo kuwa shakiya lahaa!
