Injongo ye-transformer AC ukumelana novavanyo lombane

Ngexesha lokusebenza kwezixhobo zamandla, ukugquma kuya kuncipha kancinci kancinci phantsi kwendima yombane, ubushushu kunye nokungcangcazela komatshini ixesha elide, kubandakanya ukuwohloka ngokubanzi kunye nokuwohloka kancinci, okukhokelela kwiziphene.isiphene.

Iindlela ezahlukeneyo zovavanyo lokuthintela, nganye inamandla ayo, inokufumana iziphene kwaye ibonise imeko yokugquma, kodwa umbane wovavanyo lwezinye iindlela zovavanyo uhlala usezantsi kunombane osebenzayo wesixhobo sombane, kodwa i-AC yokumelana novavanyo lombane ngokubanzi. phezulu kunaleyo yezixhobo zamandla.I-voltage yokusebenza iphezulu, ngoko emva kokuphumelela uvavanyo, izixhobo zinomlinganiselo omkhulu wokhuseleko, ngoko ke olu vavanyo lube yindlela ebalulekileyo yokuqinisekisa ukusebenza ngokukhuselekileyo.

Nangona kunjalo, okoko umbane wovavanyo osetyenziswa kuvavanyo lokumelana nombane we-AC uphezulu kakhulu kunombane osebenzayo, amandla ombane agqithisileyo aya konyusa ilahleko yesixhobo sokugquma, ukuvelisa ubushushu, kunye nokukhutshwa, okuya kukhawulezisa uphuhliso lweziphene zokugquma.Ke ngoko, ngandlela ithile, i-AC yokumelana novavanyo lombane luvavanyo olutshabalalisayo.Ngaphambi kokuba i-AC imelane novavanyo lombane, iimvavanyo ezahlukeneyo ezingonakalisi kufuneka zenziwe kwangaphambili.

Okufana nokulinganisa ukuxhathisa kokugquma, umlinganiselo wokufunxa, i-dielectric loss factor tanδ, i-DC yokuvuza yangoku, njl. njl., hlalutya ngokubanzi iziphumo zovavanyo ukufumanisa ukuba isixhobo simanzi okanye sineziphene.Ukuba kufunyaniswe ukuba kukho ingxaki, kufuneka kuqwalaselwe kwangethuba, kwaye uvavanyo lwe-AC lokumelana ne-voltage lunokwenziwa emva kokuba isiphene sisusiwe, ukuze kuthintelwe ukuqhekeka kwe-insulation ngexesha lovavanyo lwe-AC lokumelana nombane, ukwandisa ukugquma. iziphene, ukwandisa ixesha lokulondoloza, kunye nokwandisa umsebenzi wokulungisa..

Olu vavanyo lusetyenziselwa ukungqinisisa amandla angaphandle okumelana nomgca wesiphelo kunye neetheminali zeendawo ezingathathi hlangothi kunye ne-windings apho zixhunywe khona emhlabeni kunye nezinye ii-windings.Uvavanyo lwe-AC lokumelana ne-voltage yeyona ndlela ithe ngqo nesebenzayo yokuvavanya amandla e-insulation of the transformer.Kuluncedo ekufumaneni iziphene zasekhaya kwindawo ephambili yokugquma i-transformer, njengokuba ukugquma okuphambili kwe-winding kumanzi, kuqhekezekile okanye i-winding ikhululekile ngexesha lokuthutha, umgama okhokelayo awanelanga, kwaye kukho ioli kwi-insulation engundoqo. .Iziphene ezinje ngokungcola, amaqamza omoya, kunye nokungcola okubambelela kwi-insulation ejikozayo zisebenza kakhulu.Uvavanyo lwe-AC lokumelana novavanyo lwe-voltage ye-transformer lunokwenziwa kuphela emva kokuba i-transformer izaliswe nge-oyile yokugquma esemgangathweni, igcinwe imile ixesha elithile kwaye zonke ezinye iimvavanyo zokugquma zifanelekile.

HV HIPOT YDQ series gas test transformer

Uluhlu lwe-YDQ lwegesi yohlobo lovavanyo lwesiguquli yamkela izinto ezintsha kunye nobuchwepheshe obutsha, kwaye isebenzisa i-sulphur hexafluoride njengento ephakathi.Xa kuthelekiswa ne-transformer yokuvavanya i-oyile yendabuko, ubunzima be-gas-type test transformer kuphela yi-40% -80% ye-oyile-immersed test transformer phantsi kwinqanaba elifanayo lombane kunye nomthamo.Inqanaba le-voltage yeyunithi enye inokufikelela kwi-300KV, eyona nto ifaneleke ngokukodwa kwimisebenzi yesayithi.Ineempawu zobukhulu obuncinci, ubunzima obulula, akukho ngcoliseko yeoli, kwaye ayichatshazelwa kukutshintsha kwemozulu.I-corona incinci kakhulu, uvavanyo lunokwenziwa ngaphandle kokumiswa ngexesha lokuphatha kwisiza, kwaye ubomi benkonzo bude, kwaye akukho kugcinwa kufunwayo.

Isiqhulo seMveliso: YDQ AC kunye ne-DC SF6 iiguquli zovavanyo lwegesi, iiguquli zovavanyo ezizaliswe yigesi, iiguquli zovavanyo oluphezulu-voltage, iiguquli zovavanyo lwamandla aphezulu, iziguquli zovavanyo lwe-ultra-light high-voltage, cascade high-voltage test transformers, ezizaliswe yigesi. abaguquli bokuvavanya, abaguquli bovavanyo oluzaliswe yigesi, abaguquli bovavanyo oluzaliswe yigesi, abaguquli bovavanyo olugcwele igesi olune-voltage ephezulu.
