I-VPI TYPE TRANSFORMER

Ububanzi:

Umthamo olinganiselwe: 112.5 kVA Ku-15,000 kVA

Amandla kagesi ayisisekelo: 600V Through 35 kV

Amandla kagesi esibili: 120V Kudlulela ku-15 kV

I-Vacuum Pressure Impregnation (VPI) inqubo lapho i-stator ye-electric apparatus stator noma i-rotor enesilonda ngokugcwele icwiliswa ngokuphelele e-resin. Ngenhlanganisela yemijikelezo yevacuum eyomile nemanzi kanye nengcindezi, inhlaka ihlanganiswa kulo lonke uhlelo lokufakelwa. Uma sekucutshungulwe ngokushisa, ama-winding afakwe ngaphakathi abe yisakhiwo se-monolithic ne-homogenous.

Ama-transformer ohlobo olomile we-VPI alungele izinhlelo eziningi zezimboni nezohwebo. Lawa ma-transformer ahlinzeka ngamandla amangalisayo emishini kanye ne-short-circuit, ayikho ingozi yomlilo noma yokuqhuma, akukho uketshezi olungavuza, isisindo esingaphansi kwamayunithi amakhoyili acijile angaqhathaniswa, izindleko eziphelele zobunikazi kanye nezindleko eziphansi zokuqala. Basebenzisa i-UL esohlwini lwama-220°Isistimu yokufaka u-C, kungakhathaliseki izinga lokushisa. Ukufakwa okuphansi, ukugcinwa kanye nezindleko zokusebenza kwenza ama-VPI transformers abe utshalomali oluqinile.

Ama-VPI transformer awaqhumi futhi amelana nelangabi futhi awadingi ama-vault, ama-containment dikes, noma amasistimu abizayo okucima umlilo.

Inqubo ye-VPI

Amakhoyili e-VPI transformer ayingcindezi ye-vacuum efakwe ku-varnish yokushisa okuphezulu kwe-polyester. Le nqubo ihlanganisa ukucwiliswa ngokuphelele ku-vacuum ngaphansi kwe-vacuum nengcindezi kanye nokuphulukiswa okulawulwayo kusetshenziswa izinto zokusebenza ezilawulwa ngokwezibalo ukuze kuqinisekiswe ukuvumelana.

Amakhoyili aqediwe avikeleke ngokuphumelelayo emswakama, ukungcola, kanye nokungcola okuningi kwezimboni. AMANDLA E-JIEZOU'Ama-VPI transformer ngokuvamile alungele ukusetshenziswa ngaphakathi noma ngaphandle lapho abantu besebenza futhi bephefumula.

A 220Uhlelo lokufakwa kuhlu lwe-Class UL lusetshenziswa ku-JIEZOU POWER's ama-VPI ama-transformer kungakhathaliseki izinga lokushisa elishiwo. Lolu hlelo luvumela ukukhuphuka kwezinga lokushisa okujwayelekile okungu-150. Izinga lokushisa ongakukhetha likhuphuka ngo-80futhi 115futhi ukupholisa abalandeli kuvumela umthamo wokugcwala ngokweqile.

Iziguquli ze-VPI zinikeza ukuguquguquka komklamo futhi zihlala zisetshenziselwa ukuthuthukiswa kwamandla kanye nemiklamo ye-retrofit.

Ukwakhiwa Okuyinhloko

Ama-VPI transformer asebenzisa i-step-lap ekwakhiweni kwe-mitered core ukuqinisekisa ukusebenza okuhle kanye namazinga amancane omsindo. Amajoyinti ama-mitered core avumela ukuguquguquka okusebenzayo kwemigqa yezinhlamvu zemvelo phakathi kwemilenze ewumgogodla nejoka. Ukwakhiwa kwe-step-lap kuqhubekisela phambili ukuthuthukisa ukusebenza kahle kwesihlanganisi ngokunciphisa ama-fringing ahlangene, okunciphisa ukulahlekelwa okuyinhloko kanye namanje okuthakazelisayo.

Umnyombo uklanywe futhi wakhiwe ukuze unikeze ukulahlekelwa okuphansi okungenzeka okuvela emiphumeleni ye-magnetic hysteresis nama-eddy currents. Zonke izinyathelo ezingenzeka zithathwa ukuze kuvinjelwe imisinga ejikelezayo yendawo kanye nokugwema izingcindezi zokugoba ezakhelwe ngaphakathi.

Umnyombo wakhiwe kusuka ekungeneni okuphezulu, ukugoqa okubandayo, insimbi ye-silicon egxile kokusanhlamvu. Ukuminyana kwe-Magnetic flux kugcinwa ngaphansi kwephoyinti lokugcwala. Insimbi isikwe ngokunemba ukuze kuqinisekiswe ukuthi izoba bushelelezi futhi ingabi ne-burr. Ukuze aqine futhi asekele, amajoka aphezulu naphansi aboshelwe ngokuqinile namalungu asekela insimbi. Amapuleti e-tie axhuma ama-clamp aphezulu naphansi futhi anikeze isakhiwo esiqinile sokuphakanyiswa.

Umgogodla oqediwe uhlanganiswe ne-corrosion resistant sealant ehlinzeka ngokuhlangana kwe-lamination kanye nokuvikelwa kwezindawo ezimaphakathi kuya kwezinzima.

Ukwakhiwa Kwekhoyili

Idizayini yokumayo ayidingi ukucaciswa ngaphandle uma kukhona okuthandwa yikhasimende. AMANDLA e-JIEZOU athuthukisa ukwakhiwa okumazombezombe ku-voltage yokusebenza, ileveli yomfutho eyisisekelo, namandla amanje wokujika ngakunye.

Noma nini lapho kungenzeka, ama-transformer akhiwa ngama-windings esibili esilonda kanye nama-winding primary amanxeba.

Ukwakhiwa okumazombezombe kungase kube yindilinga noma unxande kudlule u-2500 kVA kumakhoyili e-VPI. Amawinding kuma-VPI transformer anezilinganiso ezingaphezu kuka-2500 kVA ngokuvamile ayindilinga.

AMANDLA E-JIEZOU'ama-voltage aphansi e-VPI windings, i-insulation class engu-1.2 kV (600V) nangaphansi, ngokuvamile alimala kusetshenziswa izikhondatha zeshidi. Lokhu kwakhiwa kuvumela ukusatshalaliswa kwamanje kwamahhala ngaphakathi kobubanzi be-axial bekhoyili obuqeda amandla e-axial athuthukiswe kwezinye izinhlobo zama-windings ngaphansi kwezimo zesifunda esifushane.

Ikhoyili yokuqala ilinyazwa ngqo phezu kwekhoyili yesibili futhi ihlukaniswa umgoqo wokuvikela. Ama-aluminium conductors ajwayelekile ngethusi elinikezwa njengenketho.
