Inhloso ye-transformer AC ukumelana nokuhlolwa kwe-voltage

Ngesikhathi sokusebenza kwemishini yamandla, ukufakwa kancane kancane kuzowohloka ngaphansi kwesenzo senkundla kagesi, izinga lokushisa kanye nokudlidliza komshini isikhathi eside, okuhlanganisa ukuwohloka okuphelele nokuwohloka ngokwengxenye, okuholela ekulimaleni.isici.

Izindlela ezahlukahlukene zokuhlola zokuvikela, ngayinye enamandla ayo, ingathola ukukhubazeka okuthile futhi ibonise isimo sokufakelwa, kodwa i-voltage yokuhlola yezinye izindlela zokuhlola ivamise ukuba ngaphansi kune-voltage yokusebenza yemishini yamandla, kodwa i-AC ukumelana ne-voltage test voltage ngokuvamile ephakeme kunaleyo yemishini yamandla.I-voltage yokusebenza iphezulu, ngakho-ke ngemva kokuphumelela ukuhlolwa, imishini inomkhawulo omkhulu wokuphepha, ngakho-ke lokhu kuhlolwa sekuyindlela ebalulekile yokuqinisekisa ukusebenza okuphephile.

Kodwa-ke, njengoba i-voltage yokuhlola esetshenziswa ekuhlolweni kwe-AC ukumelana ne-voltage iphakeme kakhulu kune-voltage yokusebenza, i-voltage eyeqile izokhuphula ukulahleka kwe-insulating medium, ikhiqize ukushisa, nokukhipha, okuzosheshisa ukuthuthukiswa kokulimala kokufakwa kwe-insulation.Ngakho-ke, ngomqondo othile, i-AC ukumelana nokuhlolwa kwe-voltage kuwukuhlola okulimazayo.Ngaphambi kokuthi i-AC imelane nokuhlolwa kwe-voltage, ukuhlolwa okuhlukahlukene okungabhubhisi kufanele kwenziwe kusenesikhathi.

Njengokulinganisa ukumelana nokufakwa kwe-insulation, isilinganiso sokumuncwa, isici sokulahlekelwa kwe-dielectric tanδ, i-DC yokuvuza yamanje, njll., hlaziya ngokugcwele imiphumela yokuhlolwa ukuze kutholwe ukuthi okokusebenza kunomswakama noma kuqukethe ukukhubazeka.Uma kutholakala ukuthi kunenkinga, idinga ukusingathwa kusenesikhathi, futhi ukuhlolwa kwe-AC ukumelana ne-voltage kungenziwa ngemuva kokususwa kwesici, ukuze kugwenywe ukuqhekeka kwe-insulation ngesikhathi sokuhlolwa kwe-AC ukumelana nokuhlolwa kwe-voltage, ukwandisa ukwahlukanisa. amaphutha, ukwandisa isikhathi sokulungisa, nokwandisa umthwalo wokulungisa..

Lokhu kuhlola kusetshenziselwa ukuqinisekisa amandla angaphandle okumelana nesiphetho somugqa namatheminali ephoyinti amaphakathi namawindi axhunywe kuwo phansi namanye amawindi.Ukuhlolwa kwe-AC ukumelana ne-voltage kuyindlela eqondile nephumelelayo yokuhlola amandla okushisa e-transformer.Kuyasiza ekutholeni iziphambeko zasendaweni ekufakweni okuyinhloko kwe-transformer, njengokuthi ukufakwa okuyinhloko kwe-winding kunomswakama, kuqhekekile noma i-winding ikhululekile ngesikhathi sokuthutha, ibanga lokuhola alanele, futhi kukhona uwoyela ekufakweni okuyinhloko. .Amaphutha afana nokungcola, amabhamuza omoya, nokungcola okunamathela ku-insulation omazombezombe kusebenza kahle kakhulu.Ukuhlolwa kwe-AC ukumelana ne-voltage ye-transformer kungenziwa kuphela ngemuva kokuthi i-transformer igcwaliswe ngamafutha okuvikela afanelekile, agcinwe emile isikhathi esithile futhi zonke ezinye izivivinyo zokufakelwa zifanelekile.

I-HV HIPOT YDQ yochungechunge lwe-transformer yokuhlola igesi

I-YDQ yochungechunge lwegesi yokuhlola uhlobo lwe-transformer yamukela into entsha nobuchwepheshe obusha, futhi isebenzisa i-sulphur hexafluoride njengendlela ephakathi.Uma kuqhathaniswa ne-transformer yokuhlola egxilile kawoyela yendabuko, isisindo se-transformer yokuhlola uhlobo lwegesi singama-40% -80% kuphela aleso se-transformer yokuhlola ecwiliswe ngamafutha ngaphansi kwezinga le-voltage efanayo namandla.Izinga lamandla kagesi leyunithi eyodwa lingafinyelela ku-300KV, elifaneleka ngokukhethekile ukusebenza endaweni.Inezici zobukhulu obuncane, isisindo esincane, akukho ukungcoliswa kwamafutha, futhi ayithinteki ukushintsha kwesimo sezulu.I-corona incane kakhulu, ukuhlolwa kungenziwa ngaphandle kokumiswa ngesikhathi sokuphatha endaweni, futhi impilo yesevisi yinde, futhi akukho kulungiswa okudingekayo.

Isiteketiso somkhiqizo: I-YDQ AC ne-DC SF6 iziguquli zokuhlola igesi, iziguquli zokuhlola ezigcwele igesi, iziguquli zokuhlola ezine-voltage ephezulu, iziguquli zokuhlola amandla kagesi aphezulu, ama-ultra-light high-voltage test transformer, ama-cascade high-voltage test transformer, agcwele igesi iziguquli zokuhlola, iziguquli zokuhlola ezigcwele igesi, iziguquli zokuhlola ezigcwele igesi, iziguquli zokuhlola ezigcwele amandla okukhanya agcwele igesi.
