Cov teeb meem ntsig txog Asmeskas -style transformer substations

American prefabricated substation enclosures muab faib ua ob hom: cov neeg uas muaj kev khiav hauj lwm txoj kev hauv tsev (cov neeg ua hauj lwm ua hauj lwm los ntawm sab hauv lub enclosure) thiab cov uas tsis muaj txoj kev khiav hauj lwm txoj kev (cov neeg ua hauj lwm ua hauj lwm los ntawm sab nraum lub enclosure). Lub chaw ua haujlwm prefabricated tuaj yeem yog ib qho, ib qho chaw kaw lossis ib lub thawv ntim khoom tsim los ntawm ob, peb, lossis ntau qhov chaw. Lub kaw lus yuav tsum muaj lub zog txhua yam txaus los tiv thaiv kev deformation thaum thauj thiab teeb tsa. Nws yuav tsum sib zog ua kom zoo nkauj zoo nkauj thiab kev sib haum xeeb xim nrog rau ib puag ncig. Qhov siab -voltage thiab low-voltage compartments yuav tsum tau nruab nrog lub teeb pom kev zoo thiab muaj plua plav tiv thaiv thiab tiv thaiv- ntsuas condensation. Cov av noo nyob rau hauv ob qho tib si high-voltage thiab low-voltage compartments yuav tsum tsis txhob ntau tshaj 90% (ntawm 25 degree), thiab chav transformer yuav tsum zoo-ventilated. Lub kaw lus yuav tsum muaj kev ntsuas lossis cov cuab yeej siv rau kev tiv thaiv hnub ci, tiv thaiv nag, tiv thaiv xeb, thiab tiv thaiv cov tsiaj me los ntawm kev nkag mus.

Vim tias kev siv hluav taws xob ntawm Asmeskas cov chav nyob yog qhov loj thiab siab -voltage metering tsis siv, cov khoom lag luam feem ntau tsis muaj siab -voltage metering, thiab qis -voltage compartments tsis muaj ntau yam twj paj nruag thiab kev faib hluav taws xob hluav taws xob. Cov khoom lag luam feem ntau ua haujlwm los ntawm cov neeg ua haujlwm, uas feem ntau tsis muaj peev xwm tsim khoom thiab hloov kho. Yuav kom ua tau raws li cov kev cai yooj yim heev ntawm cov neeg siv, nws yog ib qho tsim nyog yuav tsum tau outsource kev tsim cov khoom siv hluav taws xob tsawg-voltage tis rau switchgear manufacturers. Vim muaj qhov chaw tsawg, tsuas yog plaub qhov qis -voltage metering circuits tuaj yeem teeb tsa. High-voltage metering, low-voltage them, thiab multi{11}}circuit configuration tsis tuaj yeem ua tiav hauv cov khoom nws tus kheej.
