Izingozi zokushisa ngokweqile kwama-transformer kagesi:
1. Umonakalo wokufakwa kwe-transformer ubangelwa kakhulu ukushisa ngokweqile, futhi ukwenyuka kwezinga lokushisa kuzonciphisa ukumelana kwamandla kagesi kanye namandla omshini wezinto zokufakwa kwe-insulation. Ngokusho kwe-IEC 354 “Iziqondiso Zomthwalo Wokusebenza Kwe-Transformer”, lapho izinga lokushisa elishisa kakhulu le-transformer lifinyelela ku-140°C, kuzokhiqizwa amabhamuza omoya ku-oyili, okuzonciphisa ukufakwa kwe-insulation noma kubangele ukushaqeka, okubangela umonakalo ku-transformer.
2. Ukushisa ngokweqile kwe-transformer kunethonya elikhulu empilweni yayo yokusebenza. Uma isigaba sokumelana nokushisa kokushisa kwe-transformer kuyi-Class A, izinga lokushisa elilinganiselwe lokushisa kwe-pilot holding winding liyi-105°C. I-GB 1094 ibeka ukuthi isilinganiso sokuphakama kwezinga lokushisa kwama-transformer acwiliswe ku-oyela angama-65K, ukuphakama kwezinga lokushisa eliphezulu likawoyela kungu-55K, kanti i-iron core kanye nethangi likaphethiloli kungu-80K. Ku-transformer, ngaphansi komthwalo olinganisiwe, indawo eshisayo kakhulu ye-winding ilawulwa ngaphansi kwama-98°C, ngokuvamile indawo eshisayo kakhulu iphakeme ngama-13°C kunezinga lokushisa eliphezulu likawoyela, okungukuthi, izinga lokushisa eliphezulu likawoyela lilawulwa ngaphansi kwama-85°C.
Ukushisa ngokweqile kwe-transformer kubonakala kakhulu njengokwenyuka okungavamile kokushisa kukawoyela. Izizathu eziyinhloko zingase zihlanganise:
(1) Ukulayisha ngokweqile kwe-transformer;
(2) Idivayisi yokupholisa iyahluleka (noma idivayisi yokupholisa ayifakwanga ngokuphelele);
(3) Iphutha langaphakathi le-transformer;
(4) Izinga lokushisa elibonisa idivayisi alichazi kahle.
Uma izinga lokushisa likawoyela we-transformer litholakala liphezulu ngendlela engavamile, izizathu ezingaba khona ezingenhla kufanele zihlolwe ngasinye ngasinye, bese kwenziwa isahlulelo esinembile. Amaphuzu ayinhloko okuhlolwa nokwelashwa yilena elandelayo:
(1) Uma ithuluzi lokusebenza libonisa ukuthi i-transformer igcwele ngokweqile, izinkomba zama-thermometer esigaba sesithathu eqembu le-transformer lesigaba esisodwa ziyafana (kungase kube nokuphambuka kwamadigri ambalwa), futhi i-transformer kanye nedivayisi yokupholisa kujwayelekile, ukwenyuka kwezinga lokushisa likawoyela kubangelwa ukugcwala ngokweqile. I-transformer iqapha (umthwalo, izinga lokushisa, isimo sokusebenza), bese ibika ngokushesha emnyangweni wokuthumela ophakeme. Kunconywa ukudlulisa umthwalo ukuze kuncishiswe ukugcwala ngokweqile futhi kufinyezwe isikhathi sokugcwala ngokweqile.
(2) Uma idivayisi yokupholisa ingafakwanga ngokugcwele, kufanele ifakwe ngokushesha. Uma idivayisi yokupholisa ingasebenzi kahle, imbangela kufanele itholakale ngokushesha, ixazululwe ngokushesha, bese ukungasebenzi kahle kuqedwa. Uma iphutha lingenakuqedwa ngokushesha, izinga lokushisa kanye nomthwalo we-transformer kumele kuqashwe ngokucophelela futhi kubikwe emnyangweni wokuthumela ophakeme kanye neminyango yokuphatha ukukhiqiza ehlobene nganoma yisiphi isikhathi ukuze kuncishiswe umthwalo wokusebenza we-transformer futhi isebenze ngokwenani elihambisanayo lokusebenza kokupholisa kanye nomthwalo wedivayisi yokupholisa ehambisanayo.
(3) Uma idivayisi yokulinganisa izinga lokushisa ekude ithumela isignali ye-alamu yokushisa futhi inani lokushisa elibonisiwe liphezulu, kodwa isibonakaliso se-thermometer esisendaweni singekho phezulu, futhi kungekho elinye iphutha ku-transformer, kungaba i-alamu engamanga yephutha lesekethe yokulinganisa izinga lokushisa ekude. Lolu hlobo lwephutha lungasuswa uma kufaneleka.
Uma izinga lokushisa likawoyela lesigaba eqenjini le-transformer lezigaba ezintathu likhuphuka, okuphakeme kakhulu kunezinga lokushisa likawoyela lokusebenza laleso sigaba ngaphansi komthwalo ofanayo kanye nezimo zokupholisa esikhathini esidlule, futhi idivayisi yokupholisa kanye ne-thermometer kujwayelekile, ukudluliselwa kokushisa kungabangelwa yi-transformer yangaphakathi. Uma kubangwa iphutha elithile, uchwepheshe kufanele aziswe ukuthi athathe isampula kawoyela ngokushesha ukuze ahlaziye i-chromatographic ukuze aphenye kabanzi ngephutha. Uma ukuhlaziywa kwe-chromatographic kukhombisa ukuthi kukhona iphutha langaphakathi ku-transformer, noma izinga lokushisa likawoyela liqhubeka nokwenyuka ngaphansi kwezimo zomthwalo kanye nokupholisa ze-transformer, i-transformer kufanele isuswe ekusebenzeni ngokuhambisana nemithethonqubo yasendaweni.
