The transformer-hal waji. Ujeeddo, qaab-dhismeedka iyo sifooyinka ugu muhiimsan ee

Waxaa machadka kaftan duug ah. On su'aasha ah ee macallinka "sida transformer ka-hal waji" guuxayaan arday ee wax ka qabashada: "! Oo-oo-oo". this dhab ahaan ku danbayso, waa dhawaajiyaan ay sabab u tahay xaqiiqda ah in marka aad guurto beerta induction soo baxdo saamaynta striction magnetic, keenaya waslad khafiif ah oo ay u gariiro Bannaanka magnetic.

The transformer-hal wajiga u dhalin karo danab talantaalli ah qiimaha load jeclaaday oo aan u baahan in sahayda awood saddex waji.

transformer kasta ka kooban yahay laba waaxood oo aasaasi ah: asaasiga ah iyo gariiradda iyaga waa aan ka yarayn laba. Mabda'a hawlgalka waa mid fudud. Sidaas darteed of maraya hadda korontada iyada oo kaari ah ee hoose ku fuuli jiray, laaluusheen sare xoog electromotive (EMF). core wuxuu ka kooban yahay taarikada ferromagnetic, i.e. kor u qaadida wax xoojinta duurka ku magnetic (fasalada gaarka ah birta korontada).

baaxadda EMF uu go'aamiyey formula ah:

E = 4,44 x F x f x ω

halkaas oo:

F - Ilodanimada inayan ee ka daadanayo magnetic;

f - inta jeer ee hadda;

ω - tirada markooda ee loogu fuuli jiray.

The awoodda load la ogolaan karo, taas oo "jiididda" transformer-hal wajiga, waxaa laga siiyaa qaybta silig ka dhigeen, kuwaas oo ku dhaawacay gariiradda iyo circuit magnetic Q, gaar ahaan permeability μ ferromagnetic. Cabirka ah ubucda iyo tirada windings ku xiran yihiin ee xisaabinta, taas oo inta badan ku xiran yahay ee shaqada koorsada ee jaamacadaha farsamo.

Si kastaba ha ahaatee, hal waji transformer danab oo awood badan ku, oo ay size more cajiib ah. On jidhkooda inta badan uu leeyahay calaamadda a liiska argument aasaasiga ah (input hadda la ogolyahay iyo voltages saarka). Si kastaba ha ahaatee, tani had iyo jeer ma aha kiiska.

In dhaqanka, repairers badan waxaa inta badan soo food leh baahida loo qabo in lagu badalo-hal waji transformer danab gubay-baxay. Si loo hubiyo haboonaanta waa in la baaraa sifooyinka qalabka, loogu tala galay si uu u bedelo.

Waxa ugu horeeyo ee la sameeyo waa in la go'aamiyo talooyin ku fuuli jiray. At gudbiyeyaasha tallaabo-down waxa uu leeyahay iska caabin ugu weyn.

Markaas, waxaa galay shabakad, waxaa suurto gal ah inay ku qiyaasto danab saarka at ula taagtaagan ah. ratio ee iyo wixii soo baxayey emf waa Wehliyaha isbedelka K. Sidoo kale waa jajab siman akhbaarta N. / N O., I.e. tirada markooda ee windings ah.

Intaas ka dib, sida load la xiran kartaa iska caabin ah variable awood (resistor) iyo ka saari sifo hadda-danab ka iyada oo qeexaysa hadda lagu qiimeeyo. Sida load ku kordhiyaa danab wax soo saarka si tartiib tartiib ah hoos u.

Gudbiyeyaasha waa xoog ma aha oo kaliya, laakiin sidoo kale cabbirka. Xaaladaha marka waxaa lagama maarmaan ah si ay u qeexaan qadar weyn ee hadda ka jirta wareeg ah iyadoo la isticmaalayo ammeter ah. Waxaa ka mid ahaa sequentially, iyo waa in ay leeyihiin iska caabin yar isku dhafan oo cross-qaybta silig weyn ee nidaamka darbo magnetic. qalab noocan oo kale ah uu noqon doono mid aad u qaali ah oo weyn, sidaas darteed isticmaali-hal waji gudbiyeyaasha hadda taas saaro saami la dhimay qiimaha, iyo iyaga quudinta in ay ammeters serial caadiga ah. Xisaabi amperage waa mid fudud, waxaa hadhay oo kaliya si aad u dalbato arrimahaasi waxay jidhka ka mid ah.
