Izingozi zokushisa ngokweqile kwama-transformer amandla:
1. Ukulimala kwe-transformer insulation ikakhulukazi kubangelwa ukushisa ngokweqile, futhi ukukhuphuka kwezinga lokushisa kuzonciphisa ukumelana nomthamo kanye namandla omshini wempahla yokuvikela. Ngokusho kwe-IEC 354 "Transformer Operation Load Guidelines", lapho izinga lokushisa elishisa kakhulu le-transformer lifinyelela ku-140 ° C, ama-bubbles omoya azokhiqizwa emafutheni, okuzonciphisa ukufakwa noma kubangele i-flashover, okwenza umonakalo ku-transformer.
2. Ukushisa ngokweqile kwe-transformer kunethonya elikhulu empilweni yayo yesevisi. Uma isigaba sokumelana nokushisa kwe-insulation se-transformer kuyi-Class A, izinga lokushisa lomkhawulo wokushisa womshayeli obambe ama-winging ngu-105°C. I-GB 1094 ibeka ukuthi umkhawulo ojwayelekile wokukhuphuka kwezinga lokushisa wama-winding e-transformer acwiliswe uwoyela ngu-65K, ukukhuphuka kwezinga lokushisa likawoyela okuphezulu ngu-55K, kanti umgogodla wensimbi nethangi likaphethiloli kungu-80K. Ku-transformer, ngaphansi komthwalo olinganiselwe, indawo eshisa kakhulu yokuvunguza ilawulwa ngaphansi kuka-98 ° C, ngokuvamile indawo eshisa kakhulu i-13 ° C ephakeme kunezinga lokushisa eliphezulu likawoyela, okungukuthi, izinga lokushisa eliphezulu likawoyela lilawulwa ngaphansi kuka-85 ° C.
Ukushisa ngokweqile kwe-Transformer kubonakala ngokuyinhloko njengokwenyuka okungavamile kwezinga lokushisa likawoyela. Izizathu eziyinhloko zingase zihlanganise:
(1) Ukugcwala kwe-transformer;
(2) Umshini wokupholisa uyahluleka (noma idivayisi yokupholisa ayifakwanga ngokugcwele);
(3) Iphutha langaphakathi le-transformer;
(4) Izinga lokushisa elibonisa ukuthi idivayisi inolwazi olungalungile.
Lapho izinga lokushisa likawoyela we-transformer litholakala liphakeme ngokungavamile, izizathu ezingenhla ezingenhla kufanele zihlolwe ngayinye ngayinye, futhi kufanele kwenziwe isinqumo esinembile. Amaphuzu abalulekile okuhlolwa nokwelashwa ami kanje:
(1) Uma ithuluzi elisebenzayo libonisa ukuthi i-transformer igcwele ngokweqile, izinkomba ze-thermometer yesigaba ezintathu zeqembu le-transformer yesigaba esisodwa zifana ngokuyisisekelo (kungase kube khona ukuphambuka kwamadigri ambalwa), futhi i-transformer kanye nedivayisi yokupholisa ijwayelekile, ukukhuphuka kwezinga lokushisa kwamafutha kubangelwa ukugcwala ngokweqile. Abaqaphi be-transformer (umthwalo, izinga lokushisa, isimo sokusebenza), futhi ngokushesha babika emnyangweni ophakeme wokuthumela. Kunconywa ukudlulisa umthwalo ukuze unciphise ukulayishwa okuningi futhi unciphise isikhathi sokulayisha.
(2) Uma idivayisi yokupholisa ingafakwanga ngokugcwele, kufanele ifakwe ngokushesha. Uma idivayisi yokupholisa ingasebenzi kahle, imbangela kufanele itholakale ngokushesha, ibhekane ngokushesha, futhi ukungasebenzi kuyaqedwa. Uma iphutha lingenakuqedwa ngokushesha, izinga lokushisa kanye nomthwalo we-transformer kufanele kuqashwe ngokucophelela futhi kubikwe emnyangweni ophakeme wokuthumela kanye neminyango yokuphatha ukukhiqiza ehlobene nganoma yisiphi isikhathi ukuze kuncishiswe umthwalo wokusebenza kwe-transformer futhi usebenze ngokuvumelana nenani elihambisanayo lokusebenza kokupholisa kanye nomthwalo wedivayisi yokupholisa ehambisanayo.
(3) Uma idivayisi yokulinganisa izinga lokushisa ekude ithumela isignali ye-alamu yezinga lokushisa futhi izinga lokushisa elibonisiwe liphezulu, kodwa inkomba ye-thermometer yasendaweni ayiphezulu, futhi lingekho elinye iphutha ku-transformer, kungase kube i-alamu engamanga yephutha lesifunda sokulinganisa izinga lokushisa elikude. Lolu hlobo lwephutha lungafakwa ngaphandle uma kufanele.
Uma izinga lokushisa lamafutha lesigaba eqenjini le-transformer lesigaba sesithathu likhuphuka, eliphakeme kakhulu kunokushisa kwamafutha okusebenza kwaleso sigaba ngaphansi komthwalo ofanayo nezimo zokupholisa esikhathini esidlule, futhi idivayisi yokupholisa kanye ne-thermometer evamile, ukudluliswa kokushisa kungase kubangelwe yi-transformer yangaphakathi. Uma kubangelwe iphutha elithile, uchwepheshe kufanele aziswe ukuthi athathe ngokushesha isampula likawoyela ukuze ahlaziye i-chromatographic ukuze aqhubeke aphenye iphutha. Uma ukuhlaziywa kwe-chromatographic kubonisa ukuthi kukhona iphutha langaphakathi ku-transformer, noma izinga lokushisa lamafutha liqhubeka likhuphuka ngaphansi kwezimo zomthwalo kanye nokupholisa kwe-transformer, i-transformer kufanele ikhishwe ekusebenzeni ngokuhambisana nemithetho yesayithi.
