Iingozi zokugqithisa kakhulu ii-transformers zamandla:
1. Umonakalo wokufakelwa kwe-transformer ubangelwa kakhulu kukushisa kakhulu, kwaye ukunyuka kobushushu kuya kunciphisa ukumelana kwe-voltage kunye namandla oomatshini wezinto zokufakelwa kwe-insulation. Ngokwe-IEC 354 “Izikhokelo zoMthwalo woMthwalo weTransformer”, xa ubushushu obushushu kakhulu be-transformer bufikelela kwi-140°C, amaqamza omoya aya kuveliswa kwioyile, nto leyo eya kunciphisa ukufakwa kwe-insulation okanye ibangele ukutsha, nto leyo eya kubangela umonakalo kwi-transformer.
2. Ubushushu obugqithisileyo be-transformer bunempembelelo enkulu kubomi bayo benkonzo. Xa udidi lokumelana nobushushu be-insulation lwe-transformer ludidi A, ubushushu obulinganiselweyo be-insulation ye-pilot holding winding yi-105°C. I-GB 1094 imisela ukuba umda ophakathi wokunyuka kobushushu be-transformer efakwe kwi-oyile yi-65K, ukunyuka kobushushu be-oyile ephezulu yi-55K, kwaye i-iron core kunye ne-fuel tank yi-80K. Kwi-transformer, phantsi komthwalo olinganisiweyo, indawo eshushu kakhulu ye-winding ilawulwa ngaphantsi kwe-98°C, ngokuqhelekileyo indawo eshushu kakhulu yi-13°C ephezulu kunobushushu be-oyile ephezulu, oko kukuthi, ubushushu be-oyile ephezulu bulawulwa ngaphantsi kwe-85°C.
Ukushisa kakhulu kwe-transformer kubonakala kakhulu njengokunyuka okungaqhelekanga kobushushu beoyile. Izizathu eziphambili zingabandakanya:
(1) Ukugqithisa kwetransformer;
(2) Isixhobo sokupholisa siyasilela (okanye isixhobo sokupholisa asifakwanga ngokupheleleyo);
(3) Ingxaki yangaphakathi yetransformer;
(4) Ubushushu obubonisa isixhobo abuchazi kakuhle.
Xa ubushushu beoyile yetransformer bufunyenwe buphezulu ngendlela engaqhelekanga, izizathu ezinokubakho ezingentla kufuneka zihlolwe nganye nganye, kwaye kwenziwe isigqibo esichanekileyo. Amanqaku aphambili ovavanyo kunye nonyango ngala alandelayo:
(1) Ukuba isixhobo sokusebenza sibonisa ukuba i-transformer igcwele kakhulu, imiqondiso yee-thermometers zesigaba sesithathu zeqela le-transformer lesigaba esinye iyafana ngokusisiseko (kunokubakho ukuphambuka okumbalwa kweedigri), kwaye i-transformer kunye nesixhobo sokupholisa ziqhelekile, ukunyuka kobushushu beoyile kubangelwa kukugcwala kakhulu. I-transformer ijonga (umthwalo, ubushushu, imeko yokusebenza), kwaye ngoko nangoko ixela kwicandelo eliphezulu lokuhambisa. Kucetyiswa ukuba kudluliselwe umthwalo ukuze kuncitshiswe ukugcwala kakhulu kwaye kuncitshiswe ixesha lokugcwala kakhulu.
(2) Ukuba isixhobo sokupholisa asifakwanga ngokupheleleyo, masifakwe ngoko nangoko. Ukuba isixhobo sokupholisa asisebenzi kakuhle, unobangela kufuneka ufunyanwe ngokukhawuleza, ujongwane naso ngoko nangoko, kwaye ukungasebenzi kakuhle kususwe. Ukuba isiphene asinakususwa ngoko nangoko, ubushushu kunye nomthwalo we-transformer kufuneka ujongwe ngokusondeleyo kwaye uxelwe kwisebe eliphambili lokuhambisa kunye namasebe olawulo lwemveliso anxulumeneyo nangaliphi na ixesha ukunciphisa umthwalo wokusebenza kwe-transformer kwaye isebenze ngokwexabiso elifanelekileyo lokusebenza kokupholisa kunye nomthwalo wesixhobo sokupholisa esifanelekileyo.
(3) Ukuba isixhobo sokulinganisa ubushushu esikude sithumela isignali yesilumkiso sobushushu kwaye ixabiso lobushushu elibonisiweyo liphezulu, kodwa isalathisi se-thermometer esikwindawo asiphezulu, kwaye akukho siphako sithile kwi-transformer, isenokuba yi-alamu yobuxoki yesiphako sesekethe yokulinganisa ubushushu esikude. Olu hlobo lwesiphako lunokukhutshwa xa kufanelekile.
Ukuba ubushushu beoyile yesigaba kwiqela le-transformer lesigaba esithathu bunyuka, obuphezulu kakhulu kunobushushu beoyile yokusebenza kweso sigaba phantsi komthwalo ofanayo kunye neemeko zokupholisa kwixesha elidlulileyo, kwaye isixhobo sokupholisa kunye ne-thermometer ziqhelekile, ukudluliselwa kobushushu kunokubangelwa yi-transformer yangaphakathi. Ukuba kukho impazamo ethile ebangelwe, ingcali kufuneka yaziswe ukuba ithathe isampuli yeoyile ngoko nangoko ukuze ihlalutywe nge-chromatographic ukuze iphande ngakumbi ngempazamo. Ukuba uhlalutyo lwe-chromatographic lubonisa ukuba kukho impazamo yangaphakathi kwi-transformer, okanye ubushushu beoyile buyaqhubeka nokunyuka phantsi kweemeko zomthwalo kunye nokupholisa ze-transformer, i-transformer kufuneka isuswe ekusebenzeni ngokuhambelana nemigaqo yendawo.
