Eyona nkcazo epheleleyo yenkqubo yokupholisa i-transformer

1. Ukumelwa kwendlela yokupholisa

Indlela yokupholisa ye-transformer ngokuqhelekileyo imelwe yindibaniselwano yeekhowudi ezine, ezime ngolu hlobo lulandelayo ukusuka kwesobunxele ukuya ekunene:

Umzekelo: I-ONAN ithetha ukuzipholisa nge-oyile, oko kukuthi, ioli yangaphakathi ijikeleza ngokwemvelo, kwaye umoya wangaphandle ujikelezwe ngokwemvelo.

Okwesibini, indlela yokupholisa ye-transformer

Indlela yokupholisa i-oyile-i-transformer yamandla antywiliselweyo, ngokobukhulu bomthamo wayo, inkqubo yokupholisa inokwahlulwa ibe: ukuzipholisa ngeoli, ukucwiliswa kwe-oyile, i-oil-immersed air-cooled, ukunyanzeliswa kweoli ye-oil-cooled, i-oil circulation. ukupholisa amanzi njalo njalo.

1. Ukuzipholisa nge-oyile

Inkqubo yokupholisa i-oil-immersed self-cooling system ayinazo izixhobo zokupholisa ezikhethekileyo, ioli ijikeleza ngokwemvelo kwi-transformer, kwaye ukushisa okuvela kwintsimbi yentsimbi kunye ne-windings idluliselwe eludongeni lwetanki okanye kwi-radiator ngokuguqulwa kweoli. Ngokobungakanani bomthamo we-transformer, inokwahlulwa ibe zizakhiwo ezintathu ezahlukeneyo:

1.1. Udonga lwebhokisi olugudileyo. I-transformer enomthamo omncinci wamkela esi sakhiwo, igobolondo yebhokisi idityaniswe ngepleyiti yensimbi, kwaye udonga lwebhokisi lugudile ngokupheleleyo;

1.2. Udonga lwebhokisi yohlobo lokupholisa imbambo. Weld ezinye iimbambo zokuchitha ubushushu kudonga lwebhokisi egudileyo ukwandisa indawo ekudibaneni nomoya, olungele iziguquli ezinomthamo omkhulu kancinci;

1.3. Umbhobho wokufudumala okanye ukupholisa kwirediyetha. Kubaguquli abanomthamo omkhulu, ukwenzela ukwandisa indawo yokupholisa yetanki yamafutha, ii-radiators ezininzi zifakwe ngaphandle kwetanki yamafutha. I-radiator isethi yemibhobho yokutshatyalaliswa kobushushu kunye neentloko eziphezulu kunye nezantsi. Susa iinxalenye.

Umzobo we-1 ubonisa indlela yokuhamba kweoli ye-oyile-immersed self-cooled transformer kunye nemibhobho yokushisa. Xa i-transformer isebenza, i-oyile kwitanki yeoli iyafudunyezwa ngenxa yokufudumeza kwentsimbi kunye nokujika, ioli eshushu iya kunyuka iye phezulu kwitanki yeoli, emva koko ifake umbhobho wokulahla ubushushu ukusuka kwindawo yokungena ephezulu. wombhobho wokuphelisa ubushushu. Phola. Ioli ebandayo ihla kumbhobho okhuphayo, kwaye emva koko igeleza kwindawo engezantsi yetanki ye-transformer ukusuka ekupheleni kombhobho, kwaye ijikeleze ngokuzenzekelayo ukuhamba kweoli, ukwenzela ukuba i-transformer core kunye ne-windings ipholile ngokufanelekileyo.

Inkqubo yokupholisa i-oil-immersed self-cooling system inesakhiwo esilula kunye nokuthembeka okuphezulu, kwaye isetyenziswa ngokubanzi kwiinguqu ezinomthamo ongaphantsi kwe-10,000kVA.

1- - itanki yamafutha; I-2 - i-core core kunye ne-winding; 3 - umbhobho wokupholisa

2. I-oyile-ifakwe emoyeni-ipholile

Inkqubo yokupholisa i-oyile-intywiliselwe emoyeni, eyaziwa ngokuba yi-oyile yendalo yokujikeleza, inkqubo yokupholisa ngenkani yomoya. Kukufakela ifeni enye okanye abaliqela ecaleni kweradiyetha nganye yetanki yeoli yesiguquli ukuze utshintshe ukuhanjiswa kwendalo komoya kukuhambisa ngenkani ukomeleza amandla okuphelisa ubushushu beradiyetha. Xa kuthelekiswa ne-self-cooling system, umphumo wokupholisa unokunyuswa nge-150% ukuya kwi-200%, elingana ne-20% ukuya kwi-40% yokwanda komthamo wemveliso ye-transformer.

Xa umthwalo umncinci, umtshini unokumiswa ukwenza i-transformer iqhube kwimodi yokuzipholisa. Xa umthwalo udlula ixabiso elithile, njenge-70% yomthwalo olinganisiweyo, umqhubi unokufakwa ngokuzenzekelayo ekusebenzeni. Le ndlela yokupholisa isetyenziswa kakhulu kwiziguquli zomthamo ophakathi ngaphezulu kwe-10,000kVA.

3. Ukujikeleza kweoli okunyanzeliswayo kupholile emoyeni

Inkqubo yokupholisa i-oyile ngokunyanzeliswa yi-air-cooled ye-transformer umthamo omkhulu. Le nkqubo yokupholisa isekelwe kwi-oyile-i-air-cooling, kwaye impompo yeoli ephantsi kwamanzi ifakwe kumbhobho wokudibanisa phakathi kwe-casing enkulu yetanki yamafutha kunye ne-radiator ene-fan (ekwabizwa ngokuba yi-cooler). Xa i-oyile yepompo isebenza, i-oyile kwi-tank ye-oyile enyanzeliswayo ifakwe kwi-radiator ukusuka kwindawo ephezulu, kwaye ingena kwi-tank yeoli ukusuka kwindawo engezantsi ye-transformer ukuze iqonde ukujikeleza kweoli okunyanzeliswayo. Umphumo wokupholisa uhambelana nesantya sokujikeleza kweoli. Umzobo we-2 ubonisa isakhiwo sokupholisa sokunyanzeliswa kwe-oyile yokujikeleza kwe-air-cooled system yokupholisa esetyenziswe kwii-transformers ezinkulu.

4. Ukupholisa kwamanzi okujikeleza kweoli ngenkani

Isixokelelwano sokupholisa samanzi sokujikeleziswa kwe-oyile ngenkani siquka impompo yeoli entywilayo ngaphantsi kwamanzi, isipholile se-oyile, umbhobho we-oyile, umbhobho wamanzi okupholisa, njl. Xa ioli inyanzelekile ukuba idlule kwi-oyile epholileyo, amanzi okupholisa asetyenziselwa ukupholisa ioli. Ngoko ke, kule nkqubo yokupholisa, ukushisa kwentsimbi kunye ne-winding kuqala idluliselwe kwioli, emva koko ukushisa kwioli kudluliselwa kumanzi apholileyo. Le ndlela yokupholisa isebenza kakuhle, kodwa iimfuno zokutywinwa kwe-transformer ziphezulu kakhulu, kwaye uxinzelelo lweoli kufuneka lube phezulu kunoxinzelelo lwamanzi okupholisa ngexesha lokupholisa. Ukujikeleza kweoli okunyanzeliswayo kwesakhiwo senkqubo yokupholisa amanzi epholileyo kuboniswe kuMfanekiso 3.
