Isingeniso esifushane se-transformer conservator
I-Conservator iyithuluzi lokugcina uwoyela elisetshenziswa ku-transformer. Umsebenzi wawo ukwandisa amafutha ethangini lamafutha lapho izinga lokushisa likawoyela likhuphuka ngenxa yokwanda komthwalo we-transformer. Ngalesi sikhathi, uwoyela omningi uzogelezela ku-conservator. Ngokuphambene nalokho, lapho izinga lokushisa lincipha, amafutha ku-conservator azogeleza ethangini lamafutha futhi ukuze alungise ngokuzenzakalelayo izinga likawoyela, okungukuthi, isilondolozi sidlala indima yokugcina uwoyela nokugcwalisa uwoyela, okungaqinisekisa ukuthi ithangi likawoyela. igcwele amafutha. Ngasikhathi sinye, njengoba isilondolozi samafutha sihlonyiswe, indawo yokuxhumana phakathi kwe-transformer nomoya iyancishiswa, futhi umswakama, uthuli kanye nokungcola kwamafutha ane-oxidized okumuncwa emoyeni kufakwa ku-precipitator ngaphansi kwesilondolozi samafutha, ngaleyo ndlela yehlisa kakhulu isivinini sokuwohloka kwamafutha e-transformer.
Isakhiwo se-oil conservator: indikimba eyinhloko yesilondolozi samafutha iyisitsha esiyicylindrical esishiselwe ngamapuleti ensimbi, futhi umthamo waso ungama-10% wevolumu yethangi lamafutha. Isilondolozi sifakwe ngokuvundlile phezu kwethangi likawoyela. Amafutha angaphakathi axhunywe nethangi likawoyela we-transformer ngepayipi elixhumayo le-relay yegesi, ukuze izinga likawoyela likhuphuke futhi liwe ngokukhululekile ngokushintsha kwezinga lokushisa. Ngaphansi kwezimo ezijwayelekile, ileveli kawoyela ephansi kunazo zonke kusilondolozi sikawoyela izoba phezulu kunesihlalo esiphakanyisiwe sesikhwama sokucindezela okuphezulu. Ebhokisini elinesakhiwo esixhunyiwe, ileveli kawoyela ephansi kakhulu kusilondolozi sikawoyela izoba phezulu kunesiqongo sekesi. Igeji yezinga likawoyela engilazi (noma igeji yezinga likawoyela) ifakwa ohlangothini lwesilondolozi samafutha ukuze kubhekwe ukuguqulwa kwezinga likawoyela kusilondolozi nganoma yisiphi isikhathi.

Ifomu le-transformer conservator
Kunezinhlobo ezintathu ze-transformer conservator: uhlobo lukathayela, uhlobo lwe-capsule kanye nohlobo lwe-diaphragm.
1. Isilondolozi samafutha ohlobo lwe-capsule sihlukanisa uwoyela we-transformer emkhathini wangaphandle ngama-capsules enjoloba ngaphakathi, futhi sinikeza uwoyela we-transformer isikhala sokunwetshwa okushisayo nokufinyela okubandayo.
2. Isilondolozi sohlobo lwe-diaphragm sisetshenziselwa ukuhlukanisa uwoyela we-transformer emkhathini wangaphandle nge-diaphragm yenjoloba futhi unikeze isikhala sokunwetshwa okushisayo nokufinyela okubandayo kwamafutha e-transformer.
3. Isilondolozi samafutha enziwe uthayela siyisinweshi sensimbi esakhiwe ngamashidi kathayela ensimbi ukuze sihlukanise uwoyela we-transformer emkhathini wangaphandle futhi sinikeze isikhala sokunwetshwa okushisayo nokufinyezwa okubandayo kwamafutha e-transformer. Isilondolozi sikawoyela sikathayela sihlukaniswe isilondolozi sangaphakathi sikawoyela kanye nesilondolozi samafutha sangaphandle. Isilondolozi sangaphakathi sikawoyela sinokusebenza okungcono kodwa umthamo omkhulu.

Ukuvalwa kwe-transformer conservator
Uhlobo lokuqala luyi-conservator yamafutha evulekile (engavaliwe), lapho amafutha e-transformer exhunywe khona ngokuqondile nomoya wangaphandle. Uhlobo lwesibili i-capsule oil conservator, eye yancishiswa kancane kancane ekusebenziseni ngoba i-capsule iguga kalula futhi iqhekeke futhi ingasebenzi kahle yokuvala. Uhlobo lwesithathu isilondolozi samafutha ohlobo lwe-diaphragm, esenziwe ngezingqimba ezimbili zendwangu yenayiloni enogqinsi oluyi-0.26rallr-0.35raln, ene-neoprene ehlanganiswe maphakathi nendawo embozwe i-cyanogen butadiene ngaphandle. Kodwa-ke, inezidingo eziphakeme zekhwalithi yokufaka nenqubo yokulungisa, futhi umphumela wayo wokusebenzisa awulungile, ikakhulukazi ngenxa yokuvuza kukawoyela nokugqoka izingxenye zenjoloba, ezithinta ukuphepha, ukwethembeka kanye nokukhiqizwa okuphucuzekile kokunikezwa kwamandla. Ngakho-ke, nayo iyancipha kancane kancane. Uhlobo lwesine luyisilondolozi samafutha esisebenzisa izakhi zensimbi ezinwebekayo njengezinxephezelo, ezingahlukaniswa zibe izigaba ezimbili: uhlobo lwamafutha angaphandle kanye nohlobo lwamafutha angaphakathi. Isilondolozi samafutha amile sangaphakathi sisebenzisa amapayipi kathayela njengesiqukathi sikawoyela. Ngokwenani lamafutha anxeshezelwe, ipayipi elilodwa noma ngaphezulu likathayela lisetshenziselwa ukubeka amapayipi kawoyela ku-chassis ngokuhambisana futhi ngendlela eqondile. Isembozo sothuli sengezwa ngaphandle. Umthamo wamafutha afaka insulating unxeshezelwa ngokuhambisa amapayipi kathayela phezulu naphansi. Ukubukeka ngokuvamile kuwunxande. Isilondolozi samafutha esivundlile sangaphandle sibekwe sivundlile kusilinda sesilondolozi samafutha ngemvuno njengesikhwama somoya. Amafutha avikelayo aqukethwe phakathi kohlangothi lwangaphandle lwezivuno kanye nesilinda, futhi umoya osesivulweni uxhunyaniswa nangaphandle. Umthamo wangaphakathi wesilondolozi sikawoyela ushintshwa ngokunwetshwa kanye nokufinyela kwemvulo ukuze kubonakale isinxephezelo sevolumu samafutha avikelayo. Umumo wangaphandle uyisilinda esivundlile:

I-conservator yohlobo olu-1 oluvulekile (i-conservator) noma ithangi likawoyela elinamandla amancane we-transformer emgqonyeni wensimbi ingeyokuqala, okungukuthi, ithangi likawoyela elixhunywe nomoya wangaphandle lisetshenziswa njengesilondolozi sikawoyela. Ngenxa yokungavalwa kwayo, uwoyela we-insulating kulula uku-oxidized futhi uthinteke umswakama. Ngemuva kokusebenza isikhathi eside, izinga likawoyela we-transformer lifakwe umoya-mpilo, kanti amanzi amancane kanye nokuqukethwe komoya kawoyela we-transformer awonakele kudlula kakhulu izinga, okubeka engcupheni enkulu ekusebenzeni okuphephile, kwezomnotho nokuthembekile kwe-transformer. kunciphisa kakhulu ukuphepha kwe-transformer kanye nempilo yesevisi yamafutha avikelayo. Njengamanje, lolu hlobo lwesilondolozi samafutha (i-conservator) luqedwa ngokuyisisekelo, olungavamile ukubonakala emakethe, noma lusetshenziswa kuphela kuma-transformer anamazinga aphansi kagesi:

I-capsule engu-2 yohlobo lwe-oil conservator i-capsule yohlobo lwe-oil conservator iyisikhwama se-nayiloni esimelana nowoyela esifakwe ngaphakathi kwendawo yokugcina uwoyela yendabuko. Ihlukanisa uwoyela we-transformer emzimbeni we-transformer emoyeni: njengoba izinga lokushisa likawoyela ku-transformer likhuphuka futhi lehla, liyaphefumula, Lapho umthamo wamafutha ushintsha, kunesikhala esanele: isimiso sayo sokusebenza ukuthi igesi ku-capsule. isikhwama sixhunyaniswa nomkhathi ngeshubhu lokuphefumula kanye nesinqamuleli somswakama. Iphansi lesikhwama se-capsule liseduze nezinga lamafutha le-conservator yamafutha. Lapho izinga likawoyela lishintsha, isikhwama se-capsule sizophinde sande noma sicindezele: ngoba isikhwama senjoloba singase siqhekeke ngenxa yezinkinga zezinto ezibonakalayo, umoya namanzi kuzongena emafutheni bese kungena ithangi likawoyela we-transformer, okuholela ekwandeni kokuqukethwe kwamanzi emafutheni, Ukusebenza kwe-insulation kunciphisa futhi ukulahlekelwa kwe-dielectric yamafutha kuyanda, okusheshisa inqubo yokuguga yamafutha okufakelwa: ngakho-ke, izinhlayiya zenjoloba ye-silicone ye-transformer zidinga ukushintshwa. Lapho isimo sokuhlanza sibucayi, i-transformer idinga ukuphoqeleka ukuthi ihlunge uwoyela noma inqume amandla okugcina.

I-3 isolated oil conservator diaphragm oil conservator ixazulula izinkinga ezithile zohlobo lwe-capsule, kodwa inkinga yekhwalithi yezinto zenjoloba kunzima ukuyixazulula, ukuze izinkinga zekhwalithi zenzeke ekusebenzeni, ezibeka usongo ekusebenzeni okuphephile kwama-transformers amandla. 4 ubuchwepheshe obamukelwe uthayela wensimbi (uwoyela wangaphakathi) ovalwe uwoyela ovalwe uphawu usuvuthiwe, Ukunwetshwa nokukhulisa into enwebekayo - ubuchwepheshe be-sheet metal expander technology for transformer, obusetshenziswe kabanzi ohlelweni lwamandla iminyaka engaphezu kwengu-20, ukugcwalisa into enwebekayo ngowoyela we-transformer futhi uvumele umongo wayo unwebe futhi unciphe phezulu naphansi ukuze unxephezele inani likawoyela. Isilondolozi sangaphakathi sikawoyela siwumgogodla othayela (1 cr18nigti) owenziwe ngepayipi le-vacuum exhaust, ipayipi lomjovo kawoyela, inkomba yezinga likawoyela, ipayipi elixhumayo eliguquguqukayo kanye nonyawo lwekhabhinethi. Yenziwe ngensimbi engagqwali enokumelana nokugqwala kwe-atmospheric kanye nokumelana nokushisa okuphezulu, okungahlangabezana nempilo yohambo olungaphezulu kuka-20000 nokubuya. Umnyombo wehla uye phezulu ngokushintsha kwezinga lokushisa likawoyela we-transformer futhi unxephezela ngokuzenzakalelayo ngokushintsha kwevolumu kawoyela we-transformer.

(1) i-damper yedivayisi yokuvikela ukucindezela ifakwe emgodini ongaphakathi we-core, ongabambezela umthelela kukhabhinethi yokugcina uwoyela okubangelwa ukwanda okungazelelwe kokucindezela kwamafutha ku-transformer. Lapho umkhawulo oyinhloko ufinyelelwa, umgogodla uzophuka, futhi umzimba we-transformer uzovikelwa ngokukhululeka kwengcindezi, ngaleyo ndlela ukwandisa ukuthembeka kokusebenza kwe-transformer. Lo msebenzi awutholakali kwezinye izilondolozi.
(2) umgogodla wakhiwe nge-core eyodwa noma ngaphezulu, nekhava yokuvikela ngaphandle. Ingaphandle lengqikithi ixhunywe emkhathini, onokushisa okuhle kokushisa kanye nomphumela we-ventilation, ingasheshisa ukuhamba kwamafutha e-transformer, inciphise izinga lokushisa likawoyela ku-transformer, futhi ithuthukise ukuthembeka kokusebenza kwe-transformer.
(3) inkomba yezinga likawoyela nayo iyafana nesandisa insimbi yeshidi ye-transformer. Ngokunwetshwa nokufinyezwa komgogodla, ibhodi lenkomba liphinde liphakame noma liwele ngomongo. Ukuzwela kuphezulu, futhi ukuguqulwa kwezinga likawoyela kungabonakala ngefasitela lokubuka elifakwe kukhava yangaphandle yokuvikela, enembile futhi enokwethenjelwa. Idivayisi ye-alamu kanye ne-switch range yokuqapha izinga likawoyela ifakwe kwivolumu yangaphandle yokuvikela, engahlangabezana nezidingo zokusebenza okungagadiwe.
(4) akukho mkhuba wezinga likawoyela wamanga: izinhlobo ezihlukahlukene zama-conservators kawoyela ezisebenzayo azikwazi ukuqeda umoya ngokuphelele, okungase kubangele izinga likawoyela wamanga. Okwesibili, ubuchwepheshe buzwela kakhulu ngenxa yokuthi umnyombo ubheka phezulu naphansi. Ngaphezu kwalokho, kukhona ibhalansi yensimbi yensimbi emgodleni, okhiqiza ingcindezi encane encane, ukuze umoya osenkabeni ungaqedwa ngokushelelayo kuze kube yilapho umoya uphela ngokuphelele futhi ufinyelela izinga likawoyela elidingekayo, ngaleyo ndlela kuqedwe izinga lamafutha angamanga.
(5) ithangi likawoyela elishintsha umpompi olayishiwe akufanele lisebenzise isinwebezi sensimbi esinothayela esishintshile sempompi yokulayisha njengengxenye ebalulekile yesiguquli. Ngesikhathi sokusebenza kwayo, idinga ukulungisa i-voltage njalo ngokuya ngesimo somthwalo. Okwesibili, ngenxa yokuthi i-arc izokhiqizwa nakanjani ngesikhathi senqubo yokulungisa futhi kuzokhiqizwa igesi ethile, evinjelwa umthamo we-expander yensimbi evalwe ngokugcwele, engahambisani nokukhululwa kwegesi ekhiqizwa ukubola kwamafutha, kudingekile ukuthumela abantu kusayithi ukuze baphele amandla njalo. Umkhiqizi noma umsebenzisi akagqugquzeli ukuthi isilondolozi esincane sikawoyela esinomshini wokushintsha umpompi olayishiwe kufanele sisebenzise isandiso sikathayela esivalwe ngokugcwele:
