Distribution Transformer Efficiency Standard
Transformer yog ib qho khoom siv hluav taws xob uas siv los hloov hluav taws xob hluav taws xob los ntawm ib lub voj voog mus rau lwm qhov. Nws yog feem ntau siv nyob rau hauv cov cheeb tsam uas high voltage hluav taws xob thauj mus los ntawm lub hwj chim kis tau tus mob kab mus rau hauv nroog, suburban, thiab nyob deb nroog, qhov twg nws yog ces nqis mus rau ib tug qis voltage theem los ntawm ib tug faib transformer. Kev ua tau zoo ntawm cov khoom siv hluav taws xob faib hluav taws xob yog qhov tseem ceeb rau kev ua haujlwm tag nrho ntawm daim phiaj hluav taws xob. Higher efficiency transformers txo lub zog nkim thiab kev khiav hauj lwm cov nqi thaum txo cov tsev xog paj emissions.
Faib transformer efficiency cov qauv, uas txawv nyob rau hauv lub teb chaws, teem lub tsawg kawg nkaus lub zog efficiency theem rau transformers tsim los yog imported rau hauv ib qho kev lag luam. Hauv Tebchaws Meskas, kev faib khoom hloov pauv tau tswj hwm los ntawm Lub Tsev Haujlwm Saib Xyuas Lub Zog (DOE). DOE's Energy Efficiency Standards for Distribution Transformers xav kom cov transformers ua tau raws li qhov tsawg kawg nkaus ua haujlwm raws li lawv qhov kev ntsuas hluav taws xob thiab lub zog uas lawv muaj peev xwm hloov tau.
Hauv xyoo 2019, DOE tau hloov kho nws cov qauv kom ncav cuag qhov ua tau zoo tshaj plaws los ntawm 2025. Cov qauv tshiab yuav tsum muaj cov tshuab hloov pauv ntawm 13% mus rau 30% ntau dua li cov qauv yav dhau los. Cov qib kev ua haujlwm tshiab yuav tsum tau ntsib los ntawm ob qho tib si kua-immersed thiab qhuav-hom transformers. Hloov pauv, qee lub tebchaws hauv Tebchaws Europe, xws li Ltalis thiab Spain, muaj lub hom phiaj ua haujlwm zoo dua li Asmeskas, thiab tau teeb tsa qhov ua tau zoo tsawg kawg nkaus txog 10% siab dua li US cov cai.
High-efficiency faib transformers muaj ntau qhov zoo dua cov qauv qis. Ua ntej, lawv txo cov hluav taws xob poob thiab cov pa hluav taws xob hauv tsev cog khoom, ua rau cov nqi txuag thiab cov txiaj ntsig ib puag ncig. Qhov thib ob, lawv tuaj yeem txo qhov kev pheej hmoo ntawm transformer overheating thiab tsis ua haujlwm, uas tuaj yeem ua rau hluav taws xob tsis zoo thiab yuav tsum tau them nyiaj ntau. High-efficiency transformers kuj tsim kom muaj cua sov tsawg, uas txhais tau hais tias lawv muaj lub neej ua haujlwm ntev dua thiab yuav tsum tau txias dua, txo cov nqi khiav haujlwm ntxiv.

Kev faib tawm transformer efficiency qauv yog qhov tseem ceeb rau kev ua tau zoo thiab kev ruaj khov ntawm cov kab hluav taws xob. Tsoom fwv thiab cov koom haum tswj hwm thoob ntiaj teb, suav nrog DOE hauv Asmeskas thiab European Union, tau teeb tsa cov qauv los txhawb kev tsim khoom thiab kev xa khoom ntawm cov khoom siv hluav taws xob zoo. High-efficiency transformers yuav txo tau lub zog poob thiab lub tsev xog paj emissions, txo nqi ua hauj lwm, thiab ncua lub neej ua hauj lwm ntawm lub transformer. Kev siv cov qauv no yuav muaj txiaj ntsig zoo rau ib puag ncig, cov neeg siv khoom, thiab kev lag luam hluav taws xob.
