Kuchita thiransifoma mawerengedwe

Kamangidwe ka lililonse thiransifoma yosavuta. Amakhala ndi pakati chitsulo, coils awiri ndi waya kumulowetsa. koyilo anacemerwa yaikulu yachiwiri - sekondale. Maonekedwe a AC voteji (U1) ndi zikusinthira (I1) choyamba koyilo fomu pakati pake penipeni ndi maginito kamwazi. Iwo amalenga EMF mwachindunji mu koyilo sekondale, amene si Ufumuyo unyolo, ndipo ali mphamvu ya mphamvu, wofanana ziro.

Ngati dera ndi zikugwirizana ndi mowa zikachitika, imbaendesa kuwonjezeka njila za mphamvu panopa mu koyilo choyamba. machitidwe a kuyankhulana pakati windings limafotokoza ndondomeko ya kusintha ndi kusokonekera kwa mphamvu ya magetsi, zomwe zili m'gulu la mawerengedwe a tiransifoma. Popeza coils onse a koyilo chachiwiri ogwirizana mu mndandanda, akamagwira zotsatira chokhala wa emf asonyezedwa pa malekezero a chipangizo.

Transformers kusonkhanitsa kuti dontho voteji mu koyilo yachiwiri ndi kagawo kakang'ono (2 - 5%), chomwe chimathandiza kutenga kopanda ofanana pa malekezero U2 ndi EMF ake zizindikiro. Chiwerengero cha U2 adzakhala / zochepa choncho, kodi kwakukulu kusiyana kuli chiwerengero cha ankasinthana wa coils awiri - n2 ndi n1.

Kubverana chiwerengero cha zigawo waya amatchedwa kusintha chiŵerengero. Iwo limanenedwa mfundo (ndipo amaimira kalata K), akuti: K = n1 / n2 = U1 / U2 = I2 / I1. Nthawi zambiri chithunzi ichi amaoneka ngati chiŵerengero cha integers awiri, mwachitsanzo 1:45, lomwe limasonyeza kuti chiwerengero cha ankasinthana mmodzi wa coils nthawi 45 zosakwana chithunzi ichi. Molingana Izi zimathandiza kuchita mawerengedwe a thiransifoma panopa.

mitima magetsi kutulutsa mitundu iwiri: W woboola pakati, zida, nthambi maginito kamwazi pawiri, ndi U-mawonekedwe - popanda kulekana. Kuchepetsa imfa N'kuthekanso ndodo chopangidwa si mosalekeza, koma wapangidwa ndi zigawo munthu woonda kukhala kutali ndi mzake ndi pepala. Nthawi zambiri mtundu cylindrical: chimango ndi superimposed pa pulayimale kumulowetsa, wokwera mipira zambiri pepala, ndi pamwamba pa izi wosanjikiza lonse yachiwiri chilonda waya.

Mawerengedwe a thiransifoma ndi angayambitse mavuto ena, koma mlengi amakonda adzabwera kwa chithandizo kwa mitunduyi chosavuta anapatsidwa pansipa. Pre kofunika kudziwa kuchuluka kwa voteji ndi magulu panopa payekha aliyense koyilo. Calculated mphamvu ya aliyense wa iwo: P2 = I2 * U2; P3 = I3 * U3; P4 = I4 * U4, kumene P2, P3, P4 - mphamvu (W), stackable windings; I2, I3, I4 - mphamvu zikusinthira (A); U2, U3, U4 - Voteji (V).

Kudziwa mphamvu okwana (P) mu mawerengedwe a thiransifoma ayenera kulowa ndalama zizindikiro windings munthu, kenako kuchulukitsa ndi chinthu cha 1.25, amene amaganizira zomvetsa: P = 1.25 (P2 + P3 + P4 + ...). Zodabwitsa ndizakuti, phindu P adzakhala kuwerengera pakati mtanda gawo (mu cm²): Q = 1.2 * kor.kv.P

Ndiyeno ndondomeko adziwe nambala n0 wa ankasinthana pa 1 Volt mfundo: n0 = 50 / Q. Chifukwa cha zimenezi, kupeza chiwerengero cha ankasinthana wa coils lapansi. Pakuti loyamba, kutenga nkhani dontho voteji mu thiransifoma, izo kukhala wolingana: N1 = 0,97 * n0 * U1
Enawo: N2 = 1.3 * n0 * U2; n2 = 1.3 * n0 * U3 ... The awiri a windings aliyense wochititsa kuchita masamu malinga ndi njira: D = 0,7 * kor.kv.1 kumene ine - mwamphamvu zikusinthira (A), anthu d - awiri (mm).

Mawerengedwe a thiransifoma walola kuti mupeze ya amperage wa mphamvu sheathe: I1 = P / U1. Patsalanso mbale kukula osadziwika mu pakati. Kupeza kofunika kuwerengera kumulowetsa dera bokosi pachimake: SM = 4 (D1 (Q) * n1 + D2 (Q) * n2 + d3 (Q) * n3 + ......), Kodi SM - m'dera (lalikulu mm. ), ndi windings onse pa zenera; D1, D2, d3 ndi d4 - awiri (mm); n1, n2, n3 ndi n4 - chiwerengero cha motsatana. Kugwiritsa chilinganizo Izi zikulongosola m'goli kumulowetsa, waya kutchinjiriza makulidwe, gawo wotanganidwa ndi chimango mu lumen wa zenera pachimake. Mtengo analandira a m'dera amusankha kukula mbale wapadera kwaulere mayikidwe a koyilo zenera ake. Pomaliza, m'pofunika kudziwa - kakakulu akonzedwa pachimake pa (b), amene analandira kuchokera njira: b = (100 * Q) / munthu, kumene - kachigawo mbale pakati (mu mm); Q - pabwalopo. Onani chovuta kwa ndondomekoyi, -. Kuchita mawerengedwe a thiransifoma (a chinthu kufufuza kapamwamba ndi kukula abwino).
