Ukusuka kuhlelo ukuya kwimodi yocingo, eyona ngcaciso ibanzi ye-grounding transformer
I-transformer esezantsi ibizwa ngokuba yi-grounding transformer ngokufutshane. Ngokutsho kwendawo yokuzalisa, i-transformer yomhlaba ingahlulwa ibe yintlobo yeoli kunye nohlobo olomileyo; Ngokwenani lezigaba, i-transformer yomhlaba ingahlulwa ibe yi-transformer yesigaba esithathu kunye ne-single-phase grounding transformer. Umsebenzi wenguqu yesiseko kukubonelela indawo yokungathathi hlangothi yokwenziwa kwenkqubo enendawo engathathi hlangothi engathathi hlangothi, elungele ukusetyenziswa kwekhoyili yokucinezela i-arc okanye imowudi yokumelana encinci, ukuze kuncitshiswe i-capacitance yangoku ukuya emhlabeni kwimeko yokumisa. Iphutha lesekethe emfutshane kuthungelwano lokuhambisa kunye nokuphucula ukuthembeka konikezelo lwamandla kwinkqubo yokuhambisa.
Uhlalutyo loKhuseleko lweTransformer kuKhuseleko lweRelay
I-transformer iyisixhobo esisisigxina ekusebenzeni okuqhubekayo, okuthenjelwa ngokuthe tye ekusebenzeni kwaye kunethuba elincinci lokungaphumeleli. Nangona kunjalo, ekubeni ininzi ye-transformers ifakwe ngaphandle, kwaye ichaphazeleka ngumthwalo ngexesha lokusebenza kunye nephutha elifutshane lesiphaluka senkqubo yamandla, iimpazamo ezahlukahlukeneyo kunye neemeko ezingaqhelekanga zenzeka ngokungaqhelekanga ngexesha lokusebenza.
I-magnetizing inrush current iyenzeka nini kwiziguquli?
01 Inrush yangokuXa i-transformer iqala ukwenziwa amandla, kwenzeka into ebizwa ngokuba yi-magnetizing inrush. Nangona imisinga yokugxalathelana idla ngokungaphazamisi njengemisinga yempazamo, ubude bexesha lemisinga ye-magnetizing inrush ingolandelelwano lwemizuzwana (xa kuthelekiswa namaxesha anempazamo).
Ukusombulula ingxaki yeziganeko ezingaqhelekanga kwiziguquli
Uhlalutyo lokusebenza okungaqhelekanga kwee-transformersIsandi seTransformer asiqhelekangaNgokukhawuleza ukuba i-transformer idibaniswe nombane, kuya kubakho isandi esichukumisayo, esibangelwa ngokukodwa kwimpembelelo ye-high-voltage magnetic flux. Ngethuba lokusebenza okuqhelekileyo, isandi se-transformer siyafana. Xa kukho ezinye ingxolo, kufuneka ufumane ngononophelo unobangela kwaye ujongane nayo.
Umgaqo, isakhiwo kunye nokusebenza kunye nokugcinwa kokukhusela igesi ye-transformer
Ukukhuselwa kwegesi kukukhusela okuphambili kwiimpazamo zangaphakathi ze-transformer. Inokusebenza ngovelwano kwi-transformer inter-turn kunye ne-inter-layer short circuits, iimpazamo ezingundoqo zentsimbi, iimpazamo zangaphakathi ze-bushing, ukuqhawulwa kwangaphakathi kwamajiko, ukuwohloka kwe-insulation kunye nokuhla kwenqanaba le-oyile. Xa iphoso lenzeka ngaphakathi kwe-oyile-i-transformer-immersed, i-arc iya kubola i-insulating material kwaye ivelise inani elikhulu legesi, eliphuma kwi-tank yeoli ukuya kwi-oyile pillow, kwaye ukuqina kwayo kuyahluka kunye nobukhulu bephutha, kubonakalisa ukuhamba komoya kunye nokuhamba kwe-oyile Ukhuseleko lwesenzo lubizwa ngokuba lukhuseleko lwegesi, olukwabizwa ngokuba lukhuseleko lwerhasi. Ngethuba lokusebenza kwe-transformer, ngenxa yeempazamo zangaphakathi, ngamanye amaxesha asikwazi ukuchonga nokuthatha amanyathelo ngexesha, okulula ukubangela ezinye izingozi. Emva kokukhuselwa kwe-relay yegesi, ukuvela kweziganeko ezifanayo kunokuphetshwa kwinqanaba elithile.
Ngaba uyazi ukuba zeziphi iimeko ezifunekayo ekusebenzeni okufanayo kwee-transformers?
Ukusebenza okufanayo kwee-transformers kuthetha ukuba i-winding ephambili yee-transformers ezimbini okanye ngaphezulu zixhunyiwe ngokuhambelana kwi-busbar ye-voltage efanayo, kwaye i-windings yesibini ixhunyiwe ngokuhambelana kwi-busbar yomnye umbane.Intsingiselo yalo kukuba: xa enye i-transformer ihluleka, ezinye ii-transformers ezisebenza ngokufanayo zisengaqhubeka nokusebenza ukuqinisekisa ukusetyenziswa kwamandla kwabasebenzisi abalulekileyo; okanye xa i-transformer idinga ukulungiswa, i-transformer yokulinda inokudibaniswa ngokufanayo, kwaye emva koko i-transformer iya kulungiswa ikhutshwe kwaye ilungiswe. , okungenakuqinisekisa kuphela ukugcinwa okucwangcisiweyo kwe-transformer, kodwa kwakhona ukuqinisekisa ukuba ukunikezelwa kombane akuphazamiseki kwaye kuphuculwe ukuthembeka kokunikezelwa kwamandla.
Malunga nabaguquli, kufuneka wazi kakuhle amanqaku olwazi!
1. Yintoni i-transformer?Kwisekethe ye-AC, isixhobo esonyusa okanye esinciphisa amandla ombane sibizwa ngokuba yi-transformer. I-transformer inokuguqula naliphi na ixabiso le-voltage kwixabiso lombane esilidingayo kunye ne-frequency efanayo ukuhlangabezana neemfuno zokuhanjiswa kwamandla ombane, ukuhanjiswa kunye nokusetyenziswa.Umzekelo, umbane osuka kwiplanti yombane unomgangatho wamandla ombane ophantsi, kwaye amandla ombane kufuneka anyuswe ngaphambi kokuba ahanjiswe kwindawo ekude yokusetyenziswa kwamandla. Indawo yokusetyenziswa kwamandla kufuneka incitshiswe ukuya kwinqanaba lamandla ombane afanelekileyo ukubonelela ngezixhobo zombane kunye nombane wemihla ngemihla. Izixhobo.
Umonakalo we-oyile ye-transformer seepage kunye neendlela zayo zonyango
1. Ukuvuza kweoli ye-transformer akuyi kuchaphazela kakhulu ukubonakala, kodwa kubangele ukulahlekelwa kwezoqoqosho kuba i-transformer kufuneka ivalwe ukuze isuse ukuvuza. Ukuba kukho amabala amaninzi e-oyile kwisiseko somhlaba we-transformer, ingaba yingozi yomlilo.
Amanyathelo okuphucula ukuxhathisa kwi-short-circuit ye-transformers amandla
I-transformer yamandla yi-hub yokudluliselwa kunye nokuhanjiswa kwamandla ombane, kunye neyona nto ingundoqo yegridi yamandla. Ukusebenza kwayo okuthembekileyo akuhambelani kuphela nomgangatho wamandla uninzi lwabasebenzisi, kodwa kunye nokhuseleko lwenkqubo yonke. Ukuthembeka kwe-transformer yamandla kunqunywe yimeko yempilo yayo, ayixhomekeke kuphela kuyilo kunye nokuveliswa, izinto zokwakha, kodwa zihambelana ngokusondeleyo nokulungiswa kunye nokugcinwa. Ingxaki yokuphucula ukuchasana kwe-short-circuit of transformers kwiinkqubo zamandla kuxoxwa ngayo.
Eyona nkcazo epheleleyo yenkqubo yokupholisa i-transformer
Inkqubo yokupholisa ye-transformer yamandla iqulethwe ngamacandelo amabini: inkqubo yokupholisa yangaphakathi, eqinisekisa ukuba ukushisa kwe-winding kunye nentsimbi yentsimbi kuchithwa kwindawo ejikelezileyo; inkqubo yokupholisa yangaphandle, eqinisekisa ukuba ubushushu obuphakathi buchithwa ngaphandle kwe-transformer. Ngokobungakanani bomthamo we-transformer, i-medium kunye nohlobo lokujikeleza, i-transformer ithatha iindlela ezahlukeneyo zokupholisa.
Umahluko phakathi komgaqo wesenzo sokukhanya okuguquguqukayo okuphambili kunye nokukhusela igesi enzima
Izixhobo ezihambelanayo zokukhusela ziya kufakwa kwiimpazamo ze-short-circuit ye-transformer lead ingcingo, i-bushings kunye ne-internals, kwaye iya kuhlangabezana nezi mfuno zilandelayo:I-1) I-transformer ehambayo enye ye-10MVA nangaphezulu kunye ne-parallel running transformer ye-6.3MVA nangaphezulu kufuneka ixhotyiswe ngokhuseleko oluhlukeneyo lwe-longitudinal. I-transformers ebalulekileyo kunye ne-6.3MVA kwaye ingaphantsi isebenza ngokuzimeleyo nayo inokuxhotyiswa ngokukhuselwa kokwahlukana kwe-longitudinal.I-2) Abaguquleli abangaphantsi kwe-10MVA banokuxhotyiswa ngokukhuselwa ngokukhawuleza kwangoku kunye nokukhuselwa ngokugqithisileyo. Kwi-transformers ye-2MVA nangaphezulu, xa i-coefficient yangoku ye-sensitive sensitivity yangoku ingahambelani neemfuno, ukukhuselwa kwe-longitudinal differential kufuneka kufakwe.3) 0.4MVA nangaphezulu, i-voltage ephambili yi-10kV nangaphantsi, kwaye i-coil i-transformer ene-delta-star connection, kunye nesigaba sesibini sohlobo lwe-relay yokukhusela i-overcurrent ingasetyenziswa.4) Izixhobo ezahlukeneyo zokhuseleko ezichazwe kweli nqaku ziya kusebenza ukukhulula ii-breakers zesekethe kwicala ngalinye le-transformer.
Kufuneka ubone! Inkcazo ebanzi yokubunjwa, isakhiwo, inkqubo yeoli kunye nokusebenza kwempazamo kunye nokugcinwa
I-oyile-i-transformers ye-oyile ineempawu zokutshatyalaliswa kobushushu obuhle, ilahleko ephantsi, umthamo omkhulu kunye nexabiso eliphantsi. Okwangoku, uninzi lwabaguquli bamandla asebenzayo kwigridi yi-oyile-i-transformers, apho ngaphezu kwe-80% ipholile ngokujikeleza kweoli yendalo. Yisakhiwo sokupholisa esisetyenziswa ngokuqhelekileyo ukuseta ipleyiti yesikhokelo kwi-coil ye-oil circulation transformer yendalo. Eli phepha ligxininise ekuhlalutyeni isakhiwo, ukusebenza kunye nokugcinwa kwe-oil-immersed power transformers, kwaye ihlalutya ngokuthe ngqo inkqubo yeoli ye-oyile ye-oil-immersed transformers, kwaye ihlalutye ngokufutshane iimpazamo ze-oil-immersed power transformers. Ndiyathemba ukwandisa ukuqonda kunye nohlalutyo lweziguquli zombane zelizwe lam ezintywiliselwe ngeoli.
