Incazelo ephelele kakhulu yesistimu yokupholisa ye-transformer

1. Ukumelwa kwendlela yokupholisa

Indlela yokupholisa ye-transformer ngokuvamile imelelwa yinhlanganisela yamakhodi amane, amelwe kanje kusukela kwesobunxele kuya kwesokudla:

Isibonelo: i-ONAN isho ukuzipholisa okucwiliswe ngamafutha, okungukuthi, uwoyela wangaphakathi ujikeleziswa ngokwemvelo, kanti umoya wangaphandle ujikeleziswa ngokwemvelo

Okwesibili, indlela yokupholisa ye-transformer

Indlela yokupholisa yama-transformer kagesi acwiliswe ku-oyela, ngokuya ngobukhulu bomthamo wawo, uhlelo lokupholisa lungahlukaniswa kanje: ukuzipholisa okucwiliswe ku-oyela, ukuphola komoya okucwiliswe ku-oyela, ukuphola komoya okupholisiweyo ku-oyela, ukuphola komoya okupholisiweyo ku-oyela okupholisiweyo, ukuphola komoya okupholisiweyo ku-oyela okupholisiweyo njalo njalo.

1. Ukuzipholisa okucwiliswe uwoyela

Uhlelo lokupholisa oluzipholisa olucwiliswe ngamafutha alunazo izinto ezikhethekile zokupholisa, uwoyela ujikeleza ngokwemvelo ku-transformer, futhi ukushisa okuvela enkabeni yensimbi kanye nama-windings kudluliselwa odongeni lwethangi noma ku-radiator ngokuxhuma kwamafutha. Ngokusho kobukhulu bomthamo we-transformer, ingahlukaniswa ngezakhiwo ezintathu ezahlukene:

1.1. Udonga lwebhokisi olubushelelezi. I-transformer enomthamo omncane isebenzisa lesi sakhiwo, igobolondo lebhokisi lihlanganiswe ngepuleti lensimbi, futhi udonga lwebhokisi lubushelelezi ngokuphelele;

1.2. Udonga lwebhokisi lohlobo lwembambo yokupholisa. Shisela izimbambo zokushabalalisa ukushisa odongeni lwebhokisi olubushelelezi ukuze wandise indawo ethintana nomoya, efanele ama-transformer anomthamo omkhulu kancane;

1.3. Ukupholisa ipayipi noma i-radiator. Kuma-transformer anomthamo omkhulu, ukuze kwandiswe indawo yokupholisa yethangi likaphethiloli, kufakwa ama-radiator amaningana ngaphandle kwethangi likaphethiloli. I-radiator iyisethi yamapayipi okususa ukushisa anezihloko eziphezulu nezingezansi. Susa izingxenye.

Isithombe 1 sibonisa indlela yokugeleza kwamafutha ye-transformer ezipholisa ngokwayo ecwiliswe ngamafutha enamapayipi okushisa. Lapho i-transformer isebenza, uwoyela osethangini likawoyela uyashiswa ngenxa yokushisa kwe-iron core kanye nokugoba, uwoyela oshisayo uzokhuphukela phezulu kwethangi likawoyela, bese ungena epayipini lokusabalalisa ukushisa usuka endaweni yokungena ephezulu yepayipi lokusabalalisa ukushisa. Phola. Uwoyela obandayo wehla epayipini elikhipha imisebe, bese ugeleza engxenyeni engezansi yethangi le-transformer usuka ekugcineni okuphansi kwepayipi, bese ujikeleza ngokuzenzakalelayo ukugeleza kwamafutha, ukuze i-transformer core kanye nama-windings aphole kahle.

Uhlelo lokupholisa oluzipholisa olucwiliswe ngamafutha lunesakhiwo esilula kanye nokuthembeka okuphezulu, futhi lusetshenziswa kabanzi kuma-transformer anamandla angaphansi kuka-10,000kVA.

Umfanekiso 1 Indlela yokugeleza kukawoyela ye-transformer ezipholisa ngokwayo ecwiliswe uwoyela

1- - ithangi likaphethiloli; 2 - insimbi eyinhloko kanye nokugoba; 3 - ipayipi lokupholisa

2. Umoya opholile ocwiliswe uwoyela

Uhlelo lokupholisa olupholiswe ngomoya olucwiliswe uwoyela, olwaziwa nangokuthi ukujikeleziswa kwemvelo kwamafutha, uhlelo lokupholisa olupholiswe ngomoya oluphoqelelwe. Luwukufaka ifeni elilodwa noma amaningana eceleni kwerediyetha ngayinye yethangi likawoyela le-transformer ukushintsha ukujikeleza kwemvelo komoya kube ukujikeleza okuphoqelelwe ukuze kuthuthukiswe amandla okushisa kwerediyetha. Uma kuqhathaniswa nohlelo oluzipholisayo, umphumela wokupholisa ungandiswa ngo-150% kuya ku-200%, okulingana nokwanda okungu-20% kuya ku-40% kumandla okukhipha we-transformer.

Uma umthwalo umncane, ifeni ingamiswa ukuze i-transformer isebenze kwimodi yokuzipholisa. Uma umthwalo udlula inani elithile, njengo-70% womthwalo olinganisiwe, ifeni ingafakwa ngokuzenzakalelayo. Le ndlela yokupholisa isetshenziswa kabanzi kuma-transformer anomthamo ophakathi ngaphezu kuka-10,000kVA.

3. Ukugeleza kukawoyela okuphoqelelwe kupholiswe ngomoya

Uhlelo lokupholisa olupholishwe ngomoya olupholishwe ngomoya olujikeleza uwoyela ngenkani lwabaguquli abakhulu. Lolu hlelo lokupholisa lusekelwe ekupholisheni komoya okucwiliswe uwoyela, futhi kufakwa iphampu kawoyela engaphansi komhlabathi epayipini elixhumanisayo phakathi kwekhava eliyinhloko lethangi likaphethiloli kanye ne-radiator enefeni (ebizwa nangokuthi i-cooler). Lapho iphampu kawoyela isebenza, uwoyela osethangini likawoyela olupholishwe uyamuncwa ku-radiator usuka engxenyeni engenhla, bese ungena ethangini likawoyela usuka engxenyeni engezansi ye-transformer ukuze kufezwe ukujikeleza kukawoyela ngenkani. Umphumela wokupholisa uhlobene nesivinini sokujikeleza kukawoyela. Isithombe 2 sibonisa isakhiwo sokupholisa sohlelo lokupholisa olupholishwe ngomoya olujikeleza uwoyela olusetshenziswa kuma-transformer amakhulu.

4. Ukupholisa amanzi ngokujikeleza uwoyela okuphoqelelwe

Uhlelo lokupholisa amanzi oluqhutshwa ngogesi oluphoqelelwe luqukethe ipompo yamafutha engaphansi komhlaba, i-oyela cooler, ipayipi lamafutha, ipayipi lamanzi okupholisa, njll. Lapho lusebenza, uwoyela engxenyeni engenhla ye-transformer udonswa yipompo yamafutha bese ucindezelwa. Lapho uwoyela uphoqeleka ukuba udlule esitobhini samafutha, amanzi okupholisa asetshenziselwa ukupholisa uwoyela. Ngakho-ke, kulolu hlelo lokupholisa, ukushisa kwe-iron core kanye ne-winding kuqala kudluliselwa ku-oyela, bese ukushisa okuku-oyela kudluliselwa emanzini okupholisa. Le ndlela yokupholisa isebenza kahle, kodwa izidingo zokuvala ze-transformer ziphezulu kakhulu, futhi ingcindezi yamafutha kumele ibe phezulu kunengcindezi yamanzi okupholisa ngesikhathi senqubo yokupholisa. Isakhiwo sesistimu yokupholisa eqhutshwa ngogesi oluphoqelelwe siboniswe kuMfanekiso 3.
