Qabow: Sida loo akhriyo Koodhka qaboojinta Transformer

Hordhac

Transformer-ku wax yar ayuu u eg yahay mishiinka baabuurta: sida uu u shaqaynayo waxa uu dhaliyaa kulayl, kulaylkaasina waa in uu dibadda u baxaa, ama arrimuhu jabaan. Khasaaruhu waa sahlan yihiin mabda'a ahaan - xudunta birta waxay baabi'isaa "load-la'aan" lumin xitaa marka ay shaqaynayso, iyo dabaylaha naxaasta ah waxay baabi'iyaan "load loss" (I²R) mar kasta oo hadda socda. Haddii kulaylku aanu si degdeg ah uga bixi karin taangiga, meesha kulul ee dabaysha ayaa kor u kacaysa oo dahaarka ayaa da'da xilli hore. Nambarka afarta xaraf ah ee ku daabacan taarikada - ONAN, ONAF, OFAF, ODAF - ma aha nambarka moodeelka. Waa sharraxaad sax ah oo ku saabsan sida kulaylku u baxo , sidaas darteed inta culeyska cutubku dhab ahaantii qaadi karo.

Mabda'a iyo Noocyada

Magacaabistu waxay raacdaa IEC 60076-2 iyo IEEE C57.12.00. Afar meelood ka akhri:

• Xarafka 1aad - qaboojiye gudaha ah: O = saliidda macdanta (K = dareeraha-dabka sare / dareeraha ester, A = hawada noocyada qalalan).

• Xarafka 2aad - wareegga gudaha: N = qulqulka dabiiciga ah, F = bamka lagu qasbay, D = qulqulka toosan ee la maro marinnada dabaysha .

• Xarafka 3aad - dhexdhexaadinta dibadda: A = hawo, W = biyo.

• Xarafka 4aad - wareegga dibadda: N = dabiiciga, F = qasab.

Haddaba sallaanku wuxuu u fuulaa sidan:

• ONAN (Saliida Dabiiciga ah, Hawada Dabiiciga ah): kaligaa; marawaxad ma leh, matoob ma leh. Qiimaynta aasaasiga ah (100%).

• ONAF (Saliida Dabiiciga ah, Ciidanka Hawada): Isla socodka saliidda dabiiciga ah, laakiin taageerayaashu waxay afuufaan hiitarka. Caadi ahaan 125-133 % ee qiimaynta ONAN.

• OFAF (Oil Forced, Air Force): bamka saliidda ayaa lagu daray. Caadi ahaan cutubyada ka sarreeya ~ 20 MVA; ilaa ~140-166% ONAN.

• ODAF (Saliida hagta, Ciidanka Hawada): bamka ayaa ku riixaya saliida iyada oo la marayo dariiqyada dabaylaha, oo si toos ah u weeraraya meesha kulul. Waxaa loo adeegsaday cutubyada ugu waaweyn (200-500+ MVA).

Talaabo kasta oo kor u kac ah waxay dhaqaaqdaa kulayl badan laakiin waxay ku daraysaa qaybo dhaqaaqa, awood caawiye, iyo dayactir.

Tusaalaha Codsiga

Tixgeli koronto-beereedka hoose ee lagu magacaabo 25 MVA ONAN / 33.3 MVA ONAF / 50 MVA OFAF . Waa isku mid birta iyo naxaasta saddexda marxaladoodba. Habeenka qabow ee leh culeys fudud waxay si aamusnaan ah u socotaa 25 MVA, iyada oo ku tiirsan isugeynta. Marka culeyska iyo heerkulka kor u kaco, tusaha heerkulka-wareega (WTI) ayaa safra taageerayaasha, isagoo furaya 33.3 MVA; Haddii heerka bamka sidoo kale la awoodo, waxay gaartaa 50 MVA. Hagaha dejinta (IEEE C57.91 / IEC 60076-7) ayaa xukuma tan: ka sarreeya 98 °C tixraaca goobta kulul, gabowga dahaarka qiyaas ahaan labanlaabma 6 K kasta oo heerkul dheeri ah, sidaa darteed fasalka qaboojinta ayaa macno ahaan ka soo horjeeda nolosha dahaarka.

Fikradaha khaldan ee caadiga ah iyo Xaqiiqda Madadaalada

Fikradda khaldan: "Kaliya waxaan ku xidhi karaa taageerayaasha taransfoorka ONAN si aan u kordhiyo qiimaynteeda." Ficil ahaan jaantuska sare loo qaaday waa inuu ka yimaadaa nidaam qaboojin oo la tijaabiyay ; taageereyaasha garoonka lagu rakibay waxay buriyaan dammaanad-qaadka kulaylka ee soo-saaraha, sababtoo ah qofna si toos ah uma cabbiri karo goobta kulul ee dabaysha ee adeegga.

Xaqiiqo xiiso leh: Transformers badan oo waaweyn ayaa lagu qiimeeyay dhowr -hal magac, laba ama saddex lambar. Xitaa si ka sii wanaagsan, si qurux badan ayey u guul darraystaan: haddii taageere ama bamka uu safro, unugga ayaa si fudud hoos ugu soo degaya heerkiisa qaboojinta hoose oo wuu sii socdaa, halkii uu ka dejin lahaa khadka.
