Kuita transformer kukarukureta

The masikirwo randinenge nyore transformer. Inoitwa yesimbi chinoumba, Coils mbiri waya ichitenderera. Imwe coils akadana chikuru, wechipiri - yechipiri. The pakuonekwa AC voltage (U1) uye ano (I1) rokutanga coils chimiro paro ari rinobva nekubudisa. Zvinoita EMF zvakananga coils yechipiri, iyo isina vasiyana cheni, uye ane simba simba, zvakaenzana razero.

Kana redunhu kunofambidzana uye kuparadzwa kunoitika, inotungamirira kuti Proportional kuwedzera simba kuitika mune yokutanga coils. muenzaniso uyu kutaurirana pakati windings rinotsanangura kuchinja uye redistribution pamusoro magetsi simba, iyo yaisanganisira dzemaitirwe pamusoro transformers. Sezvo vose Coils rechipiri coils chokuita mu series, vakawana nokuda tinofanira kugara mugumisiro wacho emf kuratidzwa kumigumo mudziyo.

Transformers kuunganidza kuti donhwe voltage yechipiri coils chinhu chiduku (2 - 5%), iyo inoita kutora kubvuma wakanyatsojeka chacho yehombodo U2 uye EMF zviratidzo. Nhamba U2 huchava / zvishoma kudaro, sei hombe ndiyo musiyano pakati nhamba majana ose Coils maviri - n2 uye n1.

The ukama pakati nhamba waya akaturikidzana inonzi Kushandurwa reshiyo. Zvinonzi kunorondedzerwa yemaitiro (uye runotaurwa tsamba K), kureva: K = n1 / n2 = U1 / U2 = I2 / I1. Kazhinji nhamba iyi sokunge munhu nhamba integers maviri, somuenzaniso 1:45, iyo inoratidza kuti uwandu muchichinjana mumwe Coils 45 nguva shoma pane ichi mumwe mufananidzo. chikamu ichi chinobatsira kuita dzemaitirwe ari kuitika transformer.

Electrical cores kubereka mhando mbiri: W-zvakaumbwa, zvombo, mapazi rinobva nekubudisa migove miviri, uye U-chimiro - pasina nekupatsanurwa. Kuderedza fungidzira kurasikirwa shamhu kugadzirwa hakusi chinoenderera, asi rinoumbwa nomunhu matete akaturikidzana kuva kure kubva mumwe nokuda mapepa. Zvikuru kakawanda cylindrical mhando: puranga riri seari pasi chikuru ichitenderera, vakatasva zvakawanda mapepa balls, uye pamusoro yechipiri rukoko urwu yose muchikuvadza waya.

Kukarukureta of transformer zvingasafadza matambudziko, asi akagadzira-anoda vachauya kubatsira yeChirungu Chisina Kuoma Masvomhu dzakapiwa pazasi. Pre zvakakodzera kuona kwevari voltage uye ano mauto mumwe nomumwe nomumwe coils. Vakaverenga simba neimwe: p2 = I2 * U2; P3 = I3 * U3; P4 = I4 * U4, apo p2, P3, P4 - simba (W), stackable windings; I2, I3, I4 - simba ano (A); U2, U3, U4 - Voltage (V).

Kuti uone yose simba (P) dzemaitirwe pamusoro transformer anofanira kupinda mari zviratidzi nomumwe windings, uye ipapo kane ane chinhu pamusoro 1.25, izvo anofunga Nokurasikirwa: P = 1.25 (p2 + P3 + P4 + ...). Sezvineiwo, mutengo P kuchaita ngaaverenge makirisito muchinjikwa chikamu (mu cm²): Q = 1,2 * kor.kv.P

Zvadaro nzira kuziva nhamba n0 pamusoro muchichinjana por 1 volt kubudikidza nzira: n0 = 50 / Q. Somugumisiro, tsvaka nhamba majana ose Coils. Nokuti kutanga, kufungisisa voltage donhwe transformer, zvichava akaenzana: n1 = 0,97 * n0 * U1
Nokuti vamwe: N2 = 1.3 * n0 * U2; n2 = 1.3 * n0 * U3 ... The dhayamita upi kondakita windings zvinogona dzaona maererano nzira: D = 0,7 * kor.kv.1 apo I - ano kuchinyanya (A), D - dhayamita (mm).

Kukarukureta of transformer unokubvumira kuwana mashoko amperage simba sheathe: I1 = P / U1. Zvazvinosarira isingazivikanwi saizi mahwendefa pokupedzisira. Kuti tiwane zvakakodzera kuverenga ichitenderera nzvimbo makirisito bhokisi: Small = 4 (D1 (q) * n1 + D2 (q) * n2 + D3 (q) * n3 + ......), Where Small - nharaunda (Square mm. ), vose windings pahwindo; D1, D2, D3 uye D4 - dhayamita (mm); n1, n2, n3 uye n4 - nhamba muchichinjana. Tichishandisa nzira iyi inorondedzera gogonera ichitenderera, kuti waya kuputira ukobvu, chikamu chepamusoro pamatanda iri lumen pamusoro makirisito hwindo. Maererano vakawana kukosha nzvimbo anosarudzwa chinokosha saizi ndiro mahara placement yacho Coil pahwindo kwayo. Pakupedzisira, zvinokosha kuziva - pakukora musimboti yakatarwa (b), iyo yakatorwa nzira: b = (100 * Q) / a, uko - upamhi pakati mundiro (mu mm); Q - pachivara. Ona The wakaomesesa chikamu izvi, -. Kuti aite kukarukureta pamusoro transformer (a kutsvaga mubhawa chinhu ine akakodzera kukura).
