Hauv cov tshuab fais fab niaj hnub thiab cov khoom siv hluav taws xob, cov tiv thaiv hluav taws xob (SPDs) thiab cov inverters, ua ob qho tseem ceeb, lawv txoj kev ua haujlwm sib koom tes yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab ruaj khov ntawm tag nrho lub cev. Nrog rau kev txhim kho sai ntawm lub zog rov ua dua tshiab thiab kev siv dav dav ntawm cov khoom siv hluav taws xob fais fab, kev siv ua ke ntawm ob qho no tau dhau los ua ntau dua. Tsab xov xwm no yuav nkag mus rau hauv cov ntsiab cai ua haujlwm, cov txheej txheem xaiv, cov txheej txheem teeb tsa ntawm SPDs thiab inverters, nrog rau yuav ua li cas lawv tuaj yeem ua ke zoo tshaj plaws los muab kev tiv thaiv rau cov tshuab fais fab.

Hauv cov tshuab hluav taws xob niaj hnub no, cov khoom siv tiv thaiv hluav taws xob (SPDs) ua lub luag haujlwm tseem ceeb. Txawm hais tias nyob hauv tsev, cov chaw tsim khoom, cov chaw khaws ntaub ntawv lossis cov chaw sib txuas lus, SPDs tuaj yeem tiv thaiv tau zoo tiv thaiv kev hloov pauv hluav taws xob los ntawm xob laim, kev hloov pauv ntawm lub zog hluav taws xob thiab lwm yam, ua kom ntseeg tau tias kev ua haujlwm ntawm cov khoom siv muaj kev nyab xeeb. Tsab xov xwm no yuav qhia txog kev txhais, txoj cai ua haujlwm, txoj kev xaiv thiab phau ntawv qhia kev teeb tsa ntawm SPDs kom meej, thiab tham txog nws qhov tseem ceeb nrog cov xwm txheej ua tau. Tsis tas li ntawd, peb tseem yuav tshuaj xyuas cov txiaj ntsig loj uas yuav tshwm sim yog tias tsis muaj SPD.

Xyoo 2024, kev poob nyiaj txiag ncaj qha los ntawm xob laim thoob ntiaj teb tau nce mus txog 4.7 billion daus las Asmeskas, yuav luag 60% ntawm cov kev poob no yog vim tsis muaj kev tiv thaiv zoo ntawm cov kab ke hluav taws xob. Ua ib lub cuab yeej tseem ceeb rau kev tiv thaiv hluav taws xob ntau dhau, qhov zoo ntawm kev teeb tsa ntawm cov khoom siv tiv thaiv hluav taws xob ntau dhau (SPDs) txiav txim siab qhov kev ntseeg siab ntawm tag nrho lub zog hluav taws xob. Tsab xov xwm no yuav nkag mus rau hauv cov lus zais ntawm kev teeb tsa ntawm "tus saib xyuas hluav taws xob" no, coj koj mus rau hauv kev daws teeb meem dav dav los ntawm lub hauv paus ntsiab lus mus rau kev siv tiag tiag.

Xyoo tas los no, lub peev xwm thoob ntiaj teb ntawm photovoltaic tau tshaj 350GW, nrog rau Tuam Tshoj pab txhawb ntau dua ib feem peb. Cov thev naus laus zis ntsuab no uas hloov lub hnub ci mus ua hluav taws xob tau pom nws cov nqi poob qis los ntawm 80% hauv kaum xyoo, tab sis nws ntsib kev hem thawj ntawm xob laim - lub chaw tsim hluav taws xob hauv Arizona, Tebchaws Meskas, ib zaug poob $ 2 lab vim yog xob laim. Cov cuab yeej tiv thaiv hluav taws xob tau dhau los ua "khoom siv cawm siav" ntawm cov chaw tsim hluav taws xob, coj kaum txhiab volts ntawm xob laim hluav taws xob mus rau hauv av los ntawm peb theem kev tiv thaiv network. Cov kws tshaj lij hauv kev lag luam tau taw qhia tias thaum lub zog ntawm cov kab ke photovoltaic nce mus txog 1500V, cov khoom siv tiv thaiv tab tom coj mus rau hauv kev hloov pauv thev naus laus zis hauv cov ntaub ntawv silicon carbide.

Txij ntawm kev teeb tsa mus rau kev saib xyuas, cov ntsiab lus no yuav tsum tsis txhob raug tsis quav ntsej

Hauv cov tshuab fais fab niaj hnub no, cov khoom tiv thaiv hluav taws xob (SPD) zoo li "daim ntawv pov hwm" rau cov khoom siv hluav taws xob. Tab sis koj puas paub? Lub cuab yeej yooj yim no, yog tias ntsia lossis siv tsis raug, tsis yog tsuas yog tsis ua haujlwm tiv thaiv xwb tab sis kuj tseem yuav ua rau muaj kev phom sij rau kev nyab xeeb. Niaj hnub no, cia peb tham txog cov ntsiab lus ntawm kev siv SPDs.

Raws li lub peev xwm thoob ntiaj teb ntawm photovoltaic tau teeb tsa ntau tshaj 1TW cim, kev ntseeg siab thiab kev nyab xeeb ntawm lub kaw lus tau dhau los ua qhov tseem ceeb. Raws li cov ntaub ntawv tshiab tshaj plaws los ntawm International Electrotechnical Commission (IEC) TC82 Technical Committee, kev ua tsis tiav ntawm lub kaw lus hluav taws xob suav txog li 41.3% ntawm kev ua haujlwm thiab kev saib xyuas tsis ua haujlwm ntawm cov chaw fais fab photovoltaic, uas cov khoom siv puas tsuaj los ntawm kev hloov pauv hluav taws xob ib ntus suav txog 28.7% ntawm tag nrho cov kev ua tsis tiav. Qhov xwm txheej no tseem ceeb heev hauv thaj chaw sov thiab thaj chaw sov uas muaj cua daj cua dub ntau.

Nrog rau kev loj hlob sai ntawm kev lag luam photovoltaic thoob ntiaj teb, kev nyab xeeb thiab kev ruaj khov ntawm cov tshuab hluav taws xob hnub ci tau dhau los ua qhov tseem ceeb ntawm kev lag luam. Cov tshuab photovoltaic raug rau sab nraum zoov ntev thiab muaj kev phom sij rau kev hem thawj xws li xob laim, kev hloov pauv ntawm lub zog hluav taws xob, thiab cov khoom siv tsis ua haujlwm, uas yuav ua rau cov khoom siv puas tsuaj lossis hluav taws kub. Cov cuab yeej tiv thaiv hluav taws xob (SPDs), cov cuab yeej hluav taws xob, thiab cov fuses yog cov khoom siv tiv thaiv tseem ceeb uas txhua tus ua lawv txoj haujlwm thiab koom tes nrog ib leeg kom ntseeg tau tias kev ua haujlwm zoo ntawm lub kaw lus. Tsab xov xwm no yuav tshuaj xyuas lawv cov haujlwm, cov txheej txheem sib koom tes, thiab qhov tsim nyog los muab cov ntaub ntawv rau cov neeg siv kev lag luam.

Vim li cas koj cov khoom siv thiaj xav tau "Voltage Bodyguard"?

Xav txog qhov no: Thaum hmo ntuj muaj cua daj cua dub nrog xob laim hla saum ntuj, koj cov khoom siv raug nqi ntau pua txhiab tus tam sim ntawd "tawg tawm." Qhov no tsis yog ib qho xwm txheej los ntawm zaj yeeb yaj kiab txaus ntshai tab sis yog ib qho kev phem tiag tiag uas ntau lub Hoobkas thiab tsev neeg tau ntsib. Lub cuab yeej tiv thaiv hluav taws xob (SPD) yog "tus neeg ua yeeb yam zoo tshaj plaws" ntawm zaj dab neeg no - muaj peev xwm cuam tshuam cov hluav taws xob txaus ntshai hauv ib lab vib nas this. Tab sis ntawm no yog qhov ntes: ntau tus neeg coj tus "neeg saib xyuas" no los tsev yam tsis paub siv nws kom raug.

Niaj hnub no, cia peb tham txog tus neeg saib xyuas kev nyab xeeb hluav taws xob uas zoo li yooj yim tab sis nyuaj heev.

Hauv lub ntiaj teb niaj hnub no uas siv thev naus laus zis ntau, cov khoom siv hluav taws xob thiab khoom siv hluav taws xob muaj kev phom sij ntau dua li yav dhau los rau kev puas tsuaj los ntawm kev nce hluav taws xob los ntawm xob laim, kev hloov pauv ntawm lub grid, lossis kev ua haujlwm hloov pauv sab hauv. Cov khoom tiv thaiv hluav taws xob, tseem hu ua cov khoom siv tiv thaiv hluav taws xob (SPDs), ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov khoom siv rhiab heev ntawm kev nce hluav taws xob. Tsab xov xwm no tshawb nrhiav cov kev siv tiag tiag ntawm cov khoom tiv thaiv hluav taws xob hauv ntau yam lag luam thiab qhia txog lawv cov txiaj ntsig los ntawm kev tshawb fawb.

Kev Taw Qhia

Cov khoom tiv thaiv hluav taws xob (SPDs) yog cov khoom tseem ceeb hauv cov tshuab hluav taws xob rau kev txo cov hluav taws xob overvoltages thiab shunting surge currents. Lawv siv dav hauv ob qho tib si tam sim no ncaj qha (DC) thiab alternating current (AC) systems. Vim muaj cov yam ntxwv sib txawv ntawm DC surge protectors thiab AC surge protectors, lawv cov surge protectors kuj sib txawv heev hauv cov qauv, cov ntsiab cai ua haujlwm, thiab cov xwm txheej siv. Tsab xov xwm no yuav tshuaj xyuas qhov zoo sib xws thiab qhov sib txawv ntawm DC surge protectors thiab AC surge protectors kom meej, thiab muab cov lus qhia xaiv.
