Ukuhlaziywa Kwesizathu Sokushisa Okudlulele Kwe-Transformer

Ukuhlaziywa Kwesizathu Sokushisa Okudlulele Kwe-Transformer

Mina, imbangela yokwehluleka kwe-transformer uqobo

Ngesikhathi sokusebenza kwe-transformer, lapho ukukhiqizwa kokushisa kanye nokushabalaliswa kokushisa kufinyelela esimweni sokulinganisela, izinga lokushisa lengxenye ngayinye livame ukuba lizinzile. Uma ngaphansi kwezimo ezifanayo, izinga lokushisa likawoyela liphakeme kunokuvamile ngaphezu kuka-10°C, noma umthwalo uhlala ungashintshi, kodwa izinga lokushisa liqhubeka nokwenyuka, kungacatshangwa ukuthi kwenzeke iphutha ngaphakathi kwe-transformer.

1. Ukuthintana kabi kwe-tap changer

Ngenxa yokucindezela okunganele kwendawo yokuxhumana ye-tap changer ngesikhathi sokusebenza noma ukungcola kwendawo yokuxhumana, ukumelana kokuxhumana kuyanda. Ukwanda kokumelana kokuxhumana kuzokwenza izinga lokushisa lokuxhumana likhuphuke futhi likhiqize ukushisa. Ikakhulukazi ngemva kokushintsha ama-tap futhi lapho i-transformer igcwele ngokweqile, kulula ukwenza i-tap changer ithinte kabi futhi ikhiqize ukushisa.

Ukuxhumana okungekuhle kwe-tap changer kungahlulelwa ngesenzo esivamile segesi elula, futhi ngokuthatha amasampula kawoyela ukuze ahlolwe, kungatholakala ukuthi ukuxhumana okungekuhle kwe-tap changer kwenza iphuzu le-flash lamafutha lehle ngokushesha; ngaphezu kwalokho, i-tap inganqunywa ngokulinganisa inani lokumelana kwe-DC kwekhoyili. Isimo sokuxhumana seswishi.

2. Isekethe emfushane yekhoyili ejikayo ejikayo

Ngenxa yomonakalo wokushisa phakathi kokujika okuningana okuseduze kwekhoyili, kuzovela ugesi ojikelezayo omfushane ovaliwe. Ngesikhathi esifanayo, inani lokujika kwekhoyili yalesi sigaba liyancishiswa, futhi ukushisa okuphezulu okukhiqizwa ugesi ojikelezayo omfushane kuzokwenza ukuthi izinga lokushisa le-transformer libe phezulu kakhulu, futhi ezimweni ezimbi kakhulu, i-transformer izoshiswa.

Kunezizathu eziningi zokujikeleza okufushane phakathi kokujika kwekhoyili. Isibonelo, inqubo yokukhiqiza engalungile yekhoyili ibangela ukuthi ukufudumala komoya kulinyazwe ngomshini; izinga lokushisa eliphezulu libangela ukuthi ukufudumala komoya kuguge; Izizathu eziyinhloko ukudlula kwamandla kagesi kanye nokushisa komoya okweqile. Ukujikeleza okufushane okukhulu komoya okweqile kwenza izinga lokushisa likawoyela likhuphuke, futhi uwoyela ojikayo ojikelezayo omfushane ubonakala sengathi uyabila, futhi umsindo "wokugubha" ungezwakali. Lapho isampula kawoyela ithathwa ukuze ihlolwe, ikhwalithi kawoyela yehla futhi yathuthuka kusukela esenzweni segesi esincane kuya esenzweni segesi esindayo. Ngalesi sikhathi, ukujikeleza okufushane komoya okweqile kungatholakala nangokulinganisa ukumelana kwe-DC.

3. Ukujikeleza okufushane phakathi kwamashidi ensimbi e-silicon eyinhloko yensimbi

Ngenxa yomonakalo wamandla angaphandle noma ukuguga kokushisa kanye nezinye izizathu, ukushisa phakathi kwamashidi ensimbi e-silicon kuyonakala, umswakama we-eddy uyakhuphuka, futhi kubangwa ukushisa ngokweqile kwendawo. Ngaphezu kwalokho, umonakalo wokushisa kwesikulufu esiyinhloko nawo uyimbangela yomswakama we-eddy. Ukukhanya kubangela ukushisa kwendawo, futhi ngokuvamile ukwenyuka kwezinga lokushisa likawoyela we-transformer akubonakali; Isenzo segesi esindayo ezimweni ezinzima.

4. Ukuntuleka kwamafutha noma ukuvaleka kwepayipi lokupholisa

Uwoyela we-transformer uwumshini oyinhloko wokushisa ngaphakathi kwe-transformer, odlala indima yokushisa, ukupholisa kanye nokucima i-arc. Uma kunokuntuleka kwamafutha noma ingaphakathi lepayipi lokushisa livinjiwe, ijubane lokupholisa lokujikeleza kwamafutha lizokwehla, okuzobangela ukuba izinga lokushisa le-transformer likhuphuke ngesikhathi sokusebenza.

II. izizathu zangaphandle zokushisa okuphezulu kwe-transformer

1. Ukulayisha ngokweqile okukhulu

Ngesikhathi sokusebenza kwe-transformer, ukulahlekelwa yi-hysteresis kwe-iron core, ukulahlekelwa yi-eddy current kanye nokulahlekelwa yithusi kwe-coil konke kuguqulwa kube ukushisa, okwenza izinga lokushisa likhuphuke. Ukulahlekelwa yinsimbi kuwukulahlekelwa okuqhubekayo, okuhlobene nesakhiwo se-transformer, ngakho-ke akunakuncishiswa noma kuqedwe ngesikhathi sokusebenza, kuyilapho ukulahlekelwa yithusi kushintsha ngokushintsha komthwalo. Uma umthwalo unzima, ukwanda kokulahlekelwa yithusi kuzobangela izinga lokushisa le-transformer likhuphuke.

2. Indawo yokungena nomoya egumbini le-transformer ivaliwe noma uthuli lubi kakhulu

Ukungena komoya kanye nokuphuma komoya egumbini le-transformer kuyiziteshi zokudlulisa umoya ngesikhathi sokusebenza kwe-transformer. Uma ivinjiwe noma ihlanzwe kakhulu, izimo zokushisa ze-transformer azishintshi kodwa izimo zokushabalalisa ukushisa ziba zimbi kakhulu, futhi ukushisa akukwazi ukuhlakazeka endaweni ezungezile ngesikhathi, okuholela ekukhuphukeni kwezinga lokushisa le-transformer ngesikhathi sokusebenza. Linganisa izinga lokushisa lomoya endaweni eyi-1.5m kuya ku-2m ukusuka ethangini likawoyela le-transformer kanye nengxenye yokuphakama kwethangi likawoyela. Uma izinga lokushisa elilinganisiwe liphakeme ngo-8-10°C kunezinga lokushisa lomoya elizungezile, umoya womoya wegumbi le-transformer kufanele uthuthukiswe.

3. Ukwehluleka kwesistimu yokujikeleza kokupholisa kwe-transformer

Ngaphezu kokusebenzisa amapayipi okupholisa ukuze kuqedwe ukushisa, ama-power transformer anezindlela zokupholisa njengokupholisa umoya ngenkani, ukujikeleza kukawoyela ngenkani, kanye nokujikeleza kwamanzi. Uma uhlelo lokupholisa seluhlulekile noma izimo zokupholisa zimbi, izinga lokushisa le-transformer esebenza lizokhuphuka.
