Yintoni a owomileyo-uhlobo abaguquli? Kwizikhankanyo no Scope

Xa usebenzisa kuyimfuneko kwinqanaba lamandla ukutshintsha kwenye ombane. Owomileyo-type abaguquli (ngenye indlela - emoyeni-zipholile) owenza lo msebenzi ngokukhuselekileyo nangempumelelo kangokuba esisetyenziswa ngokubanzi ufakelo ngaphakathi kwizakhiwo zikarhulumente zokuhlala, apho ezinye iintlobo zezi zixhobo zithathwa ukuba ibe yingozi kakhulu.

Iintlobo transformer: ulwelo lomile

Enyanisweni, kukho iindidi ezimbini ezahlukeneyo zixhobo: a ubushushu ulwelo Ukupholisa (uhlobo ulwelo) kunye zipholile ngomoya okanye air-irhasi umxube (uhlobo eyomileyo).

Kuba yokuqala uhlobo sombane okupholisa medium inokuba yioli ngezimbiwa oluqhelekileyo. Kwakhona isicelo kwezinye izinto, ezifana hydrocarbon lula kunye neencindi abicah. Ezi abaguquli babe engundoqo kunye engathi antywiliselwa kwitanki equlathe eliphakathi engamanzi, nto leyo ukhonza yokwambathisa, kunye kupholile.

Uninzi abaguquli amandla efanayo engathi ezomileyo ezilayishwe epoxy intlaka ukukhonza nje yokwambathisa. Ikhusela abaqhubi ngothuli umhlwa komoya. Noko ke, ekubeni ukungunda ekubunjweni ekwazi zisetyenziswa kuphela ubukhulu esingatshintshiyo, kunokwenzeka ukuba ukutshintsha kuyilo izixhobo ezinjalo ingaphantsi. Xa uluhlu ezisetyenziswa ngokuxhaphakileyo umbane yombane kwamashishini zoshishino amancinci, kwakunye Izakhiwo zikarhulumente zokuhlala, eyomileyo-type abaguquli kuzidyuplikheyitha ngokupheleleyo inani umthamo osi ulwelo.

The main iparameters

Lo mzuzu kakhulu ebaluleke kakhulu ekusebenzeni yamacebo ingqalelo - kukuqinisekisa ukuba iqondo lobushushu engathi. Ukuze kunceda ukhetho okanye ukuthenga isixhobo for owomileyo-uhlobo umbane izinto ezahlukeneyo, cinga i parameters yokusebenza esisiseko embalwa:

1. KVA.
2. Le ombane rated le engathi zaseprayimari nasesekondari.
3. inkqubo yokuhanjiswa ubushushu Heat - isixa obushushu ubuninzi kokugquma lobushushu + avareji nokonyuka engathi + umahluko phakathi komndilili weqondo lobushushu nokonyuka engathi kunye nani liphezulu kuzo.
4. Oluphambili kunye coil - ngokubaluleka ezithile umonakalo kunokwenzeka ukuba engundoqo okanye ukuqokelelana iinyanda (ubhedu okanye aluminiyam abaqhubi).

Kukho iintlobo-ntlobo kuyilo sombane defined iindlela ezisetyenziswa ikakhulu lwe Ukuqhela engathi. Phakathi kwazo kukho eyaziwa kakuhle: Umshini ukumitha, encapsulation uphose coil. Makhe siqwalasele ngamnye kubo ngokwahlukeneyo.

Bodwa inkqubo ezincamathelayo ukumitha (VPI)

Le iteknoloji udala abaqhubi lacquer enamathela ngokuthi alternating kwengcinezelo kunye cleaner imijikelo. VPI-nkqubo isebenzisa ipholiyesta nentlaka. Inika abaqhubi endaba ngaphezu ngokuntywiliselwa eziqhelekileyo kuqamba. Ohlobo, wayigubungela ngazo, ngoko ibekwe ezikweni, apho ukubhaka. Bathi bakufika ukumelana ukuya isenzeko kokukhutshwa corona ngakumbi. njani transformer onjalo? Photo yokuthatyathwa ngezantsi.

Wedwa ngu ezincamathelayo encapsulation (VPE)

Le ndlela ungcono jikelele ukuba VPI-nkqubo. immersions ezininzi zongezwa ngexesha lenkqubo yokuvelisa ukudibanisa coil, emva kokuba umsebenzi wokosa ezikweni ukutyabeka. Ezi abaguquli zezona nkuselo nxamnye bume ndlongondlongo yaye kufumile ngaphezu kwabo VPI-analogue. njani transformer onjalo? Amafoto thaca esingezantsi.

Encapsulation (uphawu)

abaguquli anyityiliselwe - isixhobo aqhelekileyo kunye jiko wayifulela iikhompawundi lesilicon okanye epoxy intlaka kunye ngokupheleleyo livalelwe a istili enzima. inkqubo Production ezalise kwentsunguzi jiko kunye epoxy intlaka kunye amandla aphezulu Heating, ukukhusela transformer ukusuka nayiphi na impembelelo yokusingqongileyo.

Siphose coil (in a oluxonxiweyo epoxy nentlaka zilinganisiwe)

Ezi zixhobo ziquka i coil, anyityiliselwe ngaphakathi an nentlaka epoxy kule nkqubo ukubunjwa. Bazele ngokupheleleyo ne resin phantsi cleaner.

Ngalinye oko kwayijikeleza ubuchule yokugquma oluhambelana ngokukodwa kwiindawo ezithile. Kubalulekile ukuqonda apho okusemandleni ukusebenzisa iindidi ezifanelekileyo izixhobo. Umzekelo, eyomileyo-type abaguquli kunye cast yokwambathisa zimalunga-50% ibiza ngaphezu VPE imveliso okanye VPI. Ngoko ke, ukukhetha uhlobo oluthile isixhobo inokuchaphazela kakhulu iindleko zizonke zeprojekthi.

Izindululo ngokukhetha i

Ukuba kuyimfuneko, ukwanda ukumelana yamanzi corona (m. E. ugesi ebangelwa ngamandla entsimini ngaphezu amandla Heating ekwambathiseni) xa kwandiswe amandla yokugaya oko kwayijikeleza asifuneki, sebenzisa VPI-uhlobo sombane.

Ukusetyenziswa a ohlobo Yamxuluba ezifuna amandla ezongezelelweyo kunye nokukhuselwa, umzekelo, kwimvelo bako, ezifana izityalo processing lwekhemikhali, izinto izityalo, kwakunye kokufaka yangaphandle. Iindawo insimbi ziquka izinto ezinokuba yingozi kwabanye engathi of owomileyo-type abaguquli, kuquka ityuwa, uthuli, iigesi bako, ukufuma kunye amasuntswana zalo.

Ukongeza, ukusongwa kunye cast intlaka babe nako oluphuculiweyo ukumelana elifutshane elide phindo ukuxinana uphawu iinkqubo ezininzi kwezoshishino.

Injineli kudla kufuneka senze ukhetho phakathi kwisixhobo kunye nentlaka waphosa okanye VPI / VPE-udidi ukusetyenziswa kwiimeko ezigqithisileyo kunye bume entsimbini. Uhlobo lokuqala sidla ingqalelo kakhulu. Abanye abenzi, Noko ke, ibonisa ukuba yokugquma abaphosa intlaka ukulawula ubomi inkonzo ye transformer. Ngumlingani lokwanda thermal ye epoxy incincane kunolo izinikezeli yobhedu. kwanda oguquguqukayo kunye nokuhla ngokutshisa iyintsimbi- ohlobo ekugqibeleni kunokubangela ngokuhlaziya le nentlaka. Kuyaqapheleka ukuba VPI-uhlobo sombane unako ukumelana ngcono iinkqubo kwaye ngoko ke ithatha ixesha elide. Ekugqibeleni, ukhetho wokugqibela kwezobunjineli ngamandla.

uhlobo Ulwelo nxamnye owomileyo

abaguquli lulwelo-ezaliswe, bakholisa ukuba ukusebenza ngaphezulu owomileyo, ngoko babe nobomi elide. Ngaphezu koko, lo eliphakathi engamanzi iphumelela ngakumbi ukupholisa kwiindawo zasekuhlaleni lobushushu phezulu engathi. Plus, a izixhobo lulwelo-ezaliswe nomthamo engcono overload.

Ngenxa yoko, eyomileyo 1000 kVA sombane kunye kwinqanaba isiqingatha ukulayisha ilahleko nama-8 kW, kunye ngokupheleleyo - 16 kW. Ngoko ke "iwaka kaThixo", kodwa ilulwelo malunga inkunkuma nesiqingatha. Namafutha "dvuhtysyachnika" kwi kwisiqingatha ilahleko umthwalo 8 kW kunye ngokupheleleyo - 16 kW. Togu zakhe esibonakala iindleko 13 26.5 kW, ngokulandelelana. Oku kuthetha ukuba ubuntshatsheli yi abaguquli ezithandabuzekayo eyomileyo ukugcina izinga ilahleko. ixabiso labo ngexesha elifanayo ephezulu kunolo ulwelo.

Ngenxa isixhobo jiko olunzulu Ukupholisa ulwelo ngakumbi ube neempawu ezincinane (ubunzulu nobubanzi) kunokuba owomileyo umthamo efanayo. Oku kuba nesiphumo kwindawo eyimfuneko sezitishana sombane (ingakumbi eyakhelwe-in), kwaye ke ngoko iindleko ziko yonke. Ngaloo ndlela, a kVa owomileyo esiveza sombane 1000 ibe nobunzulu 1.6 m kunye nobubanzi 2,44 m. Kulo mzekelo, neoli efanayo xa ngokusondeleyo ubunzulu umntu ububanzi malunga 1.5 m. Kodwa olu hlobo kuye, Noko ke, ezinye kuneengxaki.

Umzekelo, ukhuseleko emlilweni kubaluleke ngakumbi ukuba abaguquli usebenzisa ulwelo medium okupholisa olukwazi lomlilo. Noko ke, eyomileyo-type abaguquli nako ukubamba umlilo. esebenza ngendlela engeyiyo fluid-uhlobo izixhobo bangaze zisenokuqhushumba.

Ngokuxhomekeke kwiimeko yokusebenza ye amanqaku lulwelo-ezaliswe ingafuna isixhobo pallet zokuqokelela njengesipholisi kwi ezivuzayo yayo kunokwenzeka.

Mhlawumbi xa kukhethwa abaguquli inxalenye utshintsho ukusuka ukhetho ngokucacileyo uhlobo engamanzi owomileyo luphakathi 500 kW kunye 2.5 MVA, apho uhlobo sokuqala ekukhethwa kusetyenziswa kuluhlu esezantsi, kwaye eyesibini ngaphezu kwayo.

Into ebalulekileyo ekukhetheni uhlobo transformer yofakelo indawo, ezifana ngaphakathi okanye ngaphandle kwesakhiwo ofisi, kunye nokulondolozwa imithwalo mveliso.

Owomileyo-type abaguquli rated ngaphezulu kwe 5MVa ezifumaneka lula, kodwa uninzi lwazo lulwelo-kuzaliswa. Kokufaka ngaphandle, kwanaloo nto uhlobo esikhulu.

A amagama ambalwa malunga umoya

Xa mayixhotyiswe umthwalo sombane blower fan nande kakhulu. Ngoko ke, ngokuba engathi waphosa umsebenzi olunjalo phakamisa amandla umthwalo ixesha elide nge-50% ngaphezu eliyimali. Kuba VPE okanye VPI-uhlobo lwamandla inzuzo kule meko kunokuba ukuya kwi-33%.

Umzekelo, nesiguquli amandla standard kVA ku-3000 kunye coil ongangokugibisela ngezixhobo fan komoya ukunyuka yayo 4,500 Township (50%). Ngelo xesha VPE- okanye VPI-uhlobo 2500 umthamo kVA ukuba fan okupholisa kuyivusa ku 3.333 Township (33%).

Noko ke, umntu kufuneka sihlale sikhumbula ukuba ubukho blower kunciphisa ukuthembeka kakuhle kwenkqubo. Ukuba usebenza nabafundi ukuvuthela phantsi umthwalo ngaphezu akaphumeleli fan ngegama, ngoko kukho umngcipheko lokwenyani engozini enkulu, ngenxa apho transformer yonke ingaba ilahlekile.

Kuthekani emarikeni Russian?

Kubalulekile ukuphawula ukuba kwiminyaka yakutshanje notyekelo ngokuthe ukuphinda amava Europe kwasekwa eRashiya, apho ama-90% azo zonke abaguquli abatsha efakwe inxulumene uhlobo owomileyo. Ngako oko, le imarike ngayo. Namhlanje eRashiya kukho izindululo zixhobo ukusuka kumaqela amabini abavelisi. Eyokuqala kwezi kungaquka Russian, brand Italian, IsiTshayina kunye Korean. Ngokomthetho libandakanya analogs noshowo eyaziwa yemiyinge Russian: TAP, TSL, TSGL. Yimalini sombane owomileyo na? Ixabiso eqhelekileyo "namawaka kaThixo" yahluka ukusuka engange 900 lamawaka 1 yezigidi.

Iqela lesibini liquka abavelisi waseJamani kunye isiFrentshi. Basebenzisa brand series DTTH, GDNN, GDHN. Ebudeni belo iindleko efanayo loo transformer kwamanye amazwe? Ixabiso iya kuba ukususela engange efanayo "amawaka kaThixo" 1.5 ukuya 2 million.
