Cov Khoom Tiv Thaiv Surge: Lub "Daim Thaiv Tsis Pom" Tiv Thaiv Lub Neej Niaj Hnub Nim No
1. Cov Hluav Taws Xob Txaus Ntshai: Cov "Cov Neeg Tua Neeg Uas Ntshai" Hauv Peb Nruab Nrab
Hauv ib tsev neeg nyob sab nraud ntawm Bangalore, Is Nrias teb, Rajiv tseem nco qab txog qhov kev puas tsuaj los ntawm lub caij ntuj nag xyoo tas los - tom qab muaj cua daj cua dub, nws lub TV LCD tshiab, lub tub yees, thiab ob lub tshuab cua txias tsis ua haujlwm tib lub sijhawm. Tus kws kho tau kuaj pom tias nws tsis tau xav txog: "Nws tsis yog xob laim ncaj qha. Qhov kev puas tsuaj yog los ntawm lub zog hluav taws xob los ntawm lub grid."
Cov dab neeg zoo sib xws tab tom tshwm sim thoob ntiaj teb. Raws li cov ntaub ntawv los ntawm Munich Re, kev thov nyiaj pov hwm thoob ntiaj teb rau cov khoom siv hluav taws xob puas tsuaj los ntawm kev nce hluav taws xob tau nce 17% hauv xyoo 2022 xwb. Qhov txhawj xeeb ntxiv, kwv yees li 65% ntawm cov khoom siv cuam tshuam tsis muaj kev pab them nqi hloov pauv hluav taws xob tshwj xeeb.
"Cov neeg pheej tsis quav ntsej txog qhov muaj peev xwm ua puas tsuaj ntawm qhov hluav taws xob tam sim ntawd," piav qhia los ntawm Xibfwb Chen Zhiming los ntawm Department of Electrical Engineering ntawm National University of Singapore. "Kev nce hluav taws xob uas kav tsawg dua ib feem lab ntawm ib vib nas this tuaj yeem hloov kaum txhiab daus las ntawm cov khoom siv rhiab heev mus ua cov hlau seem."
2. Kev Tiv Thaiv Hluav Taws Xob Ncua: Kev Hloov Pauv Txog Kev Siv Tshuab Los Ntawm Cov Hoobkas Mus Rau Chav Nyob
Qhov kev nce ntawm cov khoom tiv thaiv hluav taws xob surge protectors yog ib qho kev hloov pauv ntawm kev nyab xeeb hluav taws xob nws tus kheej. Xyoo 1970, cov khoom siv no tsuas yog siv rau cov chaw ua haujlwm hnyav xwb. Cov engineers ntawm Siemens hauv lub teb chaws Yelemees Ruhr Valley tau teeb tsa cov qauv prototypes thaum ntxov los tiv thaiv cov kab ke tswj hwm hlau-rolling ntau lab.
Lub sijhawm tau hloov pauv lawm. Niaj hnub no, cov khoom siv tiv thaiv hluav taws xob (SPDs) tau dhau los ua ib qho uas siv ntau heev. Hauv Tokyo, cov tsev nyob niaj hnub no muaj cov txheej txheem tiv thaiv peb-txheej ua ntej. Hauv Los Angeles, cov neeg teeb tsa tsev ntse kho SPDs ua tus qauv. Thiab hauv kev lag luam hluav taws xob Huaqiangbei hauv Shenzhen, cov hlua fais fab tiv thaiv hluav taws xob nrog cov chaw nres nkoj USB muag tsawg dua 100 yuan.
"Lub lag luam no tab tom hloov pauv," Maria Gonzalez, tus kws tshuaj ntsuam xyuas ntawm Frost & Sullivan tau hais. "Cov lag luam kim heev xav tau cov kev daws teeb meem ntse thiab sib koom ua ke, thaum cov teb chaws uas tseem tab tom loj hlob xav tau kev tiv thaiv yooj yim 'zoo txaus'."
3. Lub Zeem Muag Kev Lag Luam Thoob Ntiaj Teb: Cov Kev Qhia Hauv Cheeb Tsam
Tebchaws Europe nyiam cov kev daws teeb meem uas muaj txheej txheem. Hauv Berlin, 85% ntawm cov tsev nyob tshiab suav nrog kev tiv thaiv hluav taws xob tag nrho lub tsev, uas tsav los ntawm cov cai tsim kho kom nruj.
Cov neeg siv khoom hauv North America qhia txog kev xav ua tiag tiag. Mike Johnson, tus kws hluav taws xob los ntawm Texas, hais tias, "Feem ntau cov neeg siv khoom tsuas yog xav txog SPDs tom qab raug kev poob. Nws zoo li kev pov hwm - tib neeg xav tias kev puas tsuaj yuav tsis ntaus lawv."
Nyob rau sab hnub tuaj Es Xias teb, cov neeg tsim kho tshiab tab tom kho cov kev daws teeb meem kom haum rau cov xwm txheej hauv zos. Lub tuam txhab pib tshiab hauv Thaib teb ElecSure cov SPDs uas tiv taus dej noo, tsim los rau huab cua sov, tau txais 15% ntawm kev lag luam hauv rau lub hlis tom qab pib.
4. Kev Tsis Muaj Zog Uas Tsis Tau Saib Xyuas
Txawm tias nyob rau hauv cov cheeb tsam uas muaj kev paub txog kev tiv thaiv hluav taws xob ntau, kev nkag siab yuam kev tseem muaj. Ib daim ntawv ntsuam xyuas ntawm Seoul National University tau qhia tias:
- 42% ntawm cov neeg teb tau ntseeg tias "cov khoom siv kim kim muaj kev tiv thaiv ua ke"
- 68% tsis paub tias SPDs xav tau kev hloov pauv tsis tu ncua
- Yuav luag 90% ntawm cov tsev neeg yeej tsis tau sim lawv cov kab ke grounding
"Cov kev phom sij loj tshaj plaws tsis yog cov kev pheej hmoo uas tsis paub, tab sis yog cov uas nkag siab yuam kev," Kim Min-chul ntawm Korea Electrical Safety Corporation hais.
5. Yav Tom Ntej Yog Ntawm No: Kev Tiv Thaiv Tiam Tom Ntej
Ntawm Geneva International Inventions Exhibition, lub tuam txhab Swiss GuardTech lub "self-healing" SPD tau ua rau muaj kev xav tsis thoob. Siv cov khoom siv nano, nws tuaj yeem rov zoo tom qab muaj kev kub ntxhov, raws li kev xav tau kav ntev dua kaum npaug dua li cov qauv ib txwm muaj.
Lub caij no, AI tab tom nkag mus rau hauv thaj chaw no. Huawei lub tshuab saib xyuas hluav taws xob siv kev kawm tshuab los kwv yees qhov tsis zoo ntawm lub grid, ua kom muaj kev tiv thaiv ua ntej.
"Qhov no tab tom hloov zuj zus mus dhau qhov kev tiv thaiv tsis siv zog," David Freeman, Thawj Tswj Hwm ntawm IEEE Power Electronics Society, hais. "Nws tab tom dhau los ua kev tiv thaiv ntse thiab ua ntej."
Xaus Lus: Kev Tiv Thaiv Tsis Pom, Yav Tom Ntej Pom Tau
Keeb kwm ntawm kev siv tshuab tiv thaiv hluav taws xob zoo li ib zaj dab neeg luv luv ntawm kev siv hluav taws xob niaj hnub no. Txij li cov khoom siv hauv kev lag luam uas tsis zoo mus txog rau cov neeg saib xyuas tsev ntse niaj hnub no, SPDs qhia txog tib neeg txoj kev nkag siab tob txog lub zog hluav taws xob.
Thaum kev hloov pauv huab cua zuj zus tuaj thiab huab cua hnyav zuj zus tuaj, tej zaum peb txhua tus yuav tsum nug tias: Thaum yuav lub TV ntse tshiab, peb puas yuav tsum nqis peev rau "tus neeg tiv thaiv hluav taws xob" uas ntseeg tau?
