I-Transformer ukusebenza okuqhubekayo kwemishini ye-static, ukusebenza okuthembekile, amathuba amancane okwehluleka.Kodwa ngoba iningi lama-transformer lifakwe ngaphandle, futhi lithinteka ukusebenza komthwalo kanye nomthelela wesiphambeko sesistimu yamandla inqubo yokusebenza, ngokungenakugwenywa zonke izinhlobo zamaphutha nezimo ezingavamile.
1. Amaphutha ajwayelekile nokungahleleki kwama-transformer
2. Ukucushwa kokuvikelwa kwe-transformer
3. Ukuvikelwa okungekho ugesi
(1) Ukuvikelwa kwegesi
(2) Ukuvikelwa kwengcindezi
(3) Ukuvikelwa kwezinga lokushisa nelikawoyela
(4) Ukuvikela ukuvikela isitophu okuphelele
4. Ukuvikelwa okwehlukile
(1) Magnetizing inrush yamanje ye-transformer
(2) Umgomo wokuzibamba kwesibili kwe-harmonic
(3) Umehluko ukuvikela okusheshayo-break
Yethula kafushane lokhu ekuvikelweni okuyinhloko kwe-transformer, bese uqhubeka nokwethula ukuvikelwa kwesipele kwe-transformer. Kunezinhlobo eziningi zokulungiselelwa kokuvikela okuyisipele koguquko. Nansi isingeniso esifushane kulezi zinhlobo ezimbili zokuvikelwa kokusekelayo, ukuvikelwa okuthe xaxa kanye nokuvikelwa kokusekwa kwe-transformer.
1. Ukuvikelwa ngokweqile ngokuvalelwa kabusha kwengcindezi
2. Ukuvikela okuyisisekelo kwe-transformer
Ukuvikelwa kokusekelwa kokusekelwa kwamaphutha wesigatshana esifishane kwama-transformer amakhulu naphakathi nendawo imvamisa kufaka phakathi: ukulandelana okungu-zero ukulandelana ngokweqile, ukuvikelwa kwe-zero ukulandelana kokuvikelwa kwamandla, ukuvikelwa kwegebe, njll. Okulandelayo isingeniso esifushane esisuselwe ezindleleni ezintathu ezahlukahlukene zokubeka phansi iphuzu.
(1) Iphuzu lokungathathi hlangothi lisisekelo ngqo
(2) Iphuzu elingathathi hlangothi alinasisekelo
(3) Iphuzu elingathathi hlangothi libekwe ngegebe lokukhipha
Ama-ultra-high voltage transformers onke angama-semi-insured transformer, futhi ukwahlukanisa komhlaba kwekhoyili yamaphoyinti angathathi hlangothi kubuthakathaka kunezinye izingxenye. Ukwehlukaniswa kwephoyinti elingathathi hlangothi kwehlukaniswa kalula. Ngakho-ke, ukuvikelwa kwegebe kudinga ukulungiswa.
Umsebenzi wokuvikelwa kwegebe ukuvikela ukuphepha kokuvikela iphuzu elingathathi hlangothi lephuzu elingathathi hlangothi le-transformer.
Ukuvikelwa kwegebe kutholakala ngokusebenzisa igebe lamanje i-3I0 eligeleza ngephuzu elingathathi hlangothi le-transformer kanye ne-open delta voltage 3U0 ye-busbar PT njengomgomo.
Uma iphuzu elingathathi hlangothi lephutha likhuphukela endaweni, igebe liyahlehla futhi kwenziwa igebe elikhulu lamanje i-3I0. Ngalesi sikhathi, ukuvikelwa kwegebe kuyasebenza futhi i-transformer iyanqunywa ngemuva kokubambezeleka. Ngaphezu kwalokho, lapho iphutha lomhlabathi livela ohlelweni, iphuzu lokungathathi hlangothi libekwe phansi futhi ukuvikelwa kokulandelana kwe-zero kwe-transformer kuyasebenza, futhi iphuzu lokungathathi hlangothi libekwe kuqala. Ngemuva kokuthi uhlelo lulahlekelwe indawo yokubeka phansi, uma iphutha lisekhona, i-delta voltage 3U0 evulekile ye-busbar PT izoba nkulu kakhulu, futhi ukuvikelwa kwegebe nakho kuzosebenza ngalesi sikhathi.
