Qhuav Transformers Normal Temperature
Qhov kub thiab txias ntawm cov transformers qhuav tsis tshaj 145 degree, thiab nws tuaj yeem siv tau ib txwm. Txawm li cas los xij, yog tias qhov kub thiab txias ntawm lub tshuab hloov pauv qhuav siab dhau lawm, nws yuav ua rau lub rwb thaiv tsev kom muaj hnub nyoog qeeb. Qhov kub ntawm lub transformer qis dua, qhov zoo dua.
Qhov tseeb, vim tias qhov tseeb ntawm qhov ntsuas kub ntawm hluav taws xob siv hluav taws xob hloov pauv hauv plaub lub caij ntawm txhua xyoo, lub caij ntuj sov kub tuaj yeem tshaj qhov ntsuas kub, thiab lub caij ntuj no kub feem ntau qis dua qhov ntsuas kub. Tab sis ntev npaum li qhov kev hloov pauv nruab nrab ntawm cov cua kub cua hauv plaub lub caij ntawm txhua xyoo tsis tshaj 145 degree, nws qhov kev laus ceev kuj tuaj yeem nyob rau hauv qhov qub thiab siv tau.
Qhov kub nce ntawm qhov qhuav transformers tsis tshaj 70 degree. Yog tias qhov kub thiab txias dhau lawm, kev laus ntawm cov khoom siv hluav taws xob sab hauv yuav nrawm dua. Yog tias nws tsim nyog los kho qhov kub thiab txias thaum lub sijhawm hloov pauv, nws tuaj yeem tswj tau qis dua 50 degree. Feem ntau, lub Hoobkas teeb tsa yog 90 degree los pib kiv cua rau cua sov dissipation, 120 degree pib lub tswb kub kub, thiab 160 degree mus rau qhov kub ntawm ultra-siab. Qhov siab dua qhov kub ntawm lub sijhawm ua haujlwm, qhov ntau dua qhov kev tiv thaiv tus nqi yuav, cov cua sov yuav nce ntxiv mus, thiab qhov ua tau zoo yuav txo qis. Qhov no yog ib qho teeb meem ntawm kev tawm tswv yim zoo. Yog tias nws yog F-class rwb thaiv tsev, kev ua haujlwm ib txwm raug tswj ntawm 40-60 degree tsim nyog dua. Nyob rau hauv ib txwm muaj, qhov kub ntawm ib tug qhuav transformers ua hauj lwm nyob rau hauv ib txwm tej yam kev mob mus txog 98 degree, uas yog xam tau tias yog kuj siab. Thaum ntawd ces tsis muaj load ntxiv lawm. Cov cuab yeej siv hluav taws xob tsawg feem ntau xav kom qhov ntsuas kub tsis tshaj 65 degree. Qhov kub ntau dhau yuav ua rau kom muaj kev laus ntawm cov rwb thaiv tsev ntawm cov khoom siv thiab txo nws lub neej kev pab cuam.
Rau cov coils ntawm qhuav transformers, thaum Class A insulating cov ntaub ntawv yuav tsum tau siv, lub siab tshaj plaws kev khiav hauj lwm kub yuav tsum tsawg tshaj li 65K ntawm 108 degree; Yog tias siv cov khoom siv insulating Class E, qhov siab tshaj plaws kev ua haujlwm yuav tsum yog 121 degree. Qhov kub siab tshaj plaws yuav tsum tsawg dua 78K; Yog tias chav kawm B insulating cov khoom siv, qhov siab tshaj plaws ua haujlwm kub yuav tsum tsawg dua 85K ntawm 131 degree; Yog tias chav kawm F cov khoom siv insulating siv, qhov siab tshaj plaws ua haujlwm kub yog 156 degree, qhov siab tshaj plaws kub yuav tsum tsawg dua 105K; Yog tias chav kawm H insulating khoom siv, qhov siab tshaj plaws ua haujlwm kub yuav tsum tsawg dua 125K ntawm 181 degree; Yog hais tias chav kawm C insulating khoom siv, qhov siab tshaj plaws kev khiav hauj lwm kub yuav tsum yog 221 degree, qhov siab tshaj plaws kub yuav tsum tsawg tshaj li 155K.
