Ingcaciso epheleleyo kakhulu yenkqubo yokupholisa ye-transformer

1. Indlela yokupholisa emele indlela

Indlela yokupholisa ye-transformer ngokubanzi imelwe yindibaniselwano yeekhowudi ezine, ezimelwe ngolu hlobo lulandelayo ukusuka ekhohlo ukuya ekunene:

Umzekelo: I-ONAN ithetha ukuzipholisa okuntywiliselwa kwioyile, oko kukuthi, ioyile yangaphakathi ijikeleziswa ngokwendalo, kwaye umoya wangaphandle ujikeleziswa ngokwendalo.

Okwesibini, indlela yokupholisa ye-transformer

Indlela yokupholisa yee-transformers zamandla ezintywilisiweyo kwi-oyile, ngokobukhulu bomthamo wazo, inkqubo yokupholisa inokwahlulwahlulwa ibe: ukuzipholisa okuntywilisiweyo kwi-oyile, ukuphola komoya okuntywilisiweyo kwi-oyile, ukuphola komoya okunyanzelekileyo kwi-oyile, ukuphola komoya okunyanzelekileyo kwi-oyile, ukuphola kwamanzi kwi-oyile njalo njalo.

1. Ukuzipholisa okuzintywilisela kwioyile

Inkqubo yokupholisa eyazipholisa ngokwayo entywiliselwa kwioyile ayinazo izixhobo zokupholisa ezikhethekileyo, ioyile ijikeleza ngokwendalo kwi-transformer, kwaye ubushushu obuvela kumbindi wesinyithi kunye nee-windings budluliselwa eludongeni lwetanki okanye kwi-radiator ngokudibanisa ioyile. Ngokobukhulu bomthamo we-transformer, inokwahlulwa ibe zizakhiwo ezintathu ezahlukeneyo:

1.1. Udonga lwebhokisi olugudileyo. I-transformer enomthamo omncinci iyamkela olu lwakhiwo, iqokobhe lebhokisi lidityaniswe ngepleyiti yentsimbi, kwaye udonga lwebhokisi lugudileyo ngokupheleleyo;

1.2. Udonga lwebhokisi yohlobo lwembambo yokupholisa. Shicilela ezinye iimbambo zokusasaza ubushushu eludongeni lwebhokisi olugudileyo ukuze wandise indawo edibana nomoya, efanelekileyo kwiitransformer ezinomthamo omkhulu kancinci;

1.3. Fudumeza umbhobho okanye i-radiator cooling. Kwii-transformers ezinomthamo omkhulu, ukuze kwandiswe umphezulu wokupholisa wetanki yepetroli, kufakelwa ii-radiator ezininzi ngaphandle kwetanki yepetroli. I-radiator yiseti yemibhobho yokusasaza ubushushu enezihloko eziphezulu nezisezantsi. Susa iindawo.

Umfanekiso 1 ubonisa indlela yokuhamba kweoyile yetransformer ezipholisele ngokwayo efakwe kwioyile enemibhobho yobushushu. Xa itransformer isebenza, ioyile ekwitanki yeoyile iyafudunyezwa ngenxa yokufudunyezwa kwesiseko sentsimbi kunye nokujijeka, ioyile eshushu iya kunyuka iye phezulu kwitanki yeoyile, ize ingene kumbhobho wokusasaza ubushushu ukusuka kwindawo ephezulu yombhobho wokusasaza ubushushu. Phola. Ioyile ebandayo yehla kumbhobho okhupha imisebe, ize igeleze iye kwinxalenye esezantsi yetanki yetransformer ukusuka kwisiphelo esisezantsi sombhobho, kwaye ijikeleze ngokuzenzekelayo ukuhamba kweoyile, ukuze isiseko setransformer kunye nokujijeka kuphole ngempumelelo.

Inkqubo yokuzipholisa efakwe kwi-oyile inesakhiwo esilula kwaye ithembekile kakhulu, kwaye isetyenziswa kakhulu kwiitransformer ezinomthamo ongaphantsi kwe-10,000kVA.

1- - itanki yepetroli; 2 - umbindi wentsimbi kunye nokujika; 3 - umbhobho wokupholisa

2. Ipholile emoyeni entywilisiweyo ngeoyile

Inkqubo yokupholisa epholiswe ngomoya efakwe kwi-oyile, eyaziwa ngokuba yi-oyile natural circulation, inkqubo yokupholisa epholiswe ngomoya enyanzelekileyo. Kukufaka ifeni enye okanye ezininzi ecaleni kweradiator nganye yetanki yeoyile yetransformer ukutshintsha i-convection yendalo yomoya ibe yi-convection enyanzelekileyo ukuphucula amandla okusasaza ubushushu be-radiator. Xa kuthelekiswa nenkqubo yokuzipholisa ngokwayo, isiphumo sokupholisa sinokunyuswa nge-150% ukuya kwi-200%, okulingana nokunyuka kwama-20% ukuya kuma-40% kumandla okukhupha e-transformer.

Xa umthwalo umncinci, ifeni ingamiswa ukuze i-transformer isebenze kwimo yokuzipholisa. Xa umthwalo udlula ixabiso elithile, njenge-70% yomthwalo olinganisiweyo, ifeni ingafakwa ngokuzenzekelayo. Le ndlela yokupholisa isetyenziswa kakhulu kwii-transformers ezinomthamo ophakathi ngaphezu kwe-10,000kVA.

3. Ukujikeleza kweoyile okunyanzelekileyo kupholiswe ngumoya

Inkqubo yokupholisa umoya epholisiweyo nge-oyile eqhutywa ngokunyanzela kwi-transformers ezinkulu ezinomthamo omkhulu. Le nkqubo yokupholisa isekelwe ekupholisweni komoya okuntywiliselwa kwi-oyile, kwaye kufakwa ipompo yeoyile engaphantsi komhlaba kumbhobho odibanisayo phakathi kwe-casing ephambili yetanki yepetroli kunye ne-radiator enefeni (ekwabizwa ngokuba yi-cooler). Xa ipompo yeoyile isebenza, ioyile ekwi-oyile eqhutywa ngokunyanzela ifunxwa kwi-radiator isuka kwinxalenye ephezulu, ize ingene kwi-oyile isuka kwinxalenye esezantsi ye-transformer ukuze ifezekise ukujikeleza kweoyile okunyanzelekileyo. Isiphumo sokupholisa sinxulumene nesantya sokujikeleza kweoyile. Umfanekiso 2 ubonisa isakhiwo sokupholisa senkqubo yokupholisa umoya epholisiweyo nge-oyile esetyenziswa kwi-transformers ezinkulu.

4. Ukupholisa amanzi ngokujikeleza kweoyile okunyanzelekileyo

Inkqubo yokupholisa amanzi e-oyile ephoqelekileyo iqulathe ipompo yeoyile engaphantsi komhlaba, i-oyile ephoqelekileyo, umbhobho yeoyile, umbhobho wamanzi opholisayo, njl. Xa isebenza, ioyile ekwinxalenye ephezulu ye-transformer ifunxwa yipompo yeoyile ize icinezelwe. Xa ioyile iphoqelekile ukuba idlule kwi-oyile ephoqelekileyo, amanzi okupholisa asetyenziselwa ukupholisa ioyile. Ke ngoko, kule nkqubo yokupholisa, ubushushu bombindi wesinyithi kunye nokujija kuqala kudluliselwe kwioyile, kwaye emva koko ubushushu obukwioyile budluliselwa emanzini okupholisa. Le ndlela yokupholisa isebenza kakuhle, kodwa iimfuno zokuvala ze-transformer ziphezulu kakhulu, kwaye uxinzelelo lweoyile kufuneka lube phezulu kunoxinzelelo lwamanzi okupholisa ngexesha lenkqubo yokupholisa. Ulwakhiwo lwenkqubo yokupholisa ephoqelekileyo ephoqelekileyo ephoqelekileyo ephoqelekileyo ephoqelekileyo ephoqelweyo ephoqelweyo ephoqelweyo ephoqelweyo ephoqelweyo ephoqelweyo ephoqelweyo ephoqelweyo ephoqelweyo ephoqelweyo ephoqelweyo ephoqelweyo ephoqelweyo ephoqelweyo ephoqelweyo ephoqelweyo ephoqelweni ...lweni ephoqelweyo ephoqelweni ephoqelweni ephoqelweni ephoqelweyo ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweyo ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweyo ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni ephoqelweni e
