Tawm ntawm cov laj thawj uas tau hais hauv Txoj Cai Kev Tiv Thaiv Thoob Ntiaj Teb, qhov teeb meem uas cuam tshuam rau feem ntau txoj kev teeb ci sab nraum zoov yog kev tawm tsam ncaj qha rau cov kab hluav taws xob (kis tau los ntawm kab hluav taws xob). Thaj chaw teeb tsa yuav tsum raug kuaj xyuas kom zoo thiab siv tau rau qhov tshwm sim ntawm xob laim thiab qhov tshwm sim ntawm pob hluav taws xob yog qhov siab dua, kev tiv thaiv 10kV raug pom zoo.

Kev tiv thaiv ntawm LED teeb tiv thaiv overvoltage

Overvoltage ua rau, kev paub thiab cov ntsiab lus tiv thaiv

Qhov hloov mus rau LED teeb pom kev zoo nyob rau sab hauv thiab sab nrauv teeb pom kev zoo tsis tu ncua ntxiv. Hauv lub sijhawm, ntau lub nroog cov tub ceev xwm thiab cov neeg ua haujlwm sib txuas thoob plaws Tebchaws Europe tau ntsib nrog cov txuj ci tshiab no. Nws zoo nkaus li tias qhov zoo, tshwj xeeb ntawm kev txuag hluav taws xob thiab kev tswj hwm teeb pom kev zoo, yuav ua kom paub tseeb tias qhov sib koom ntawm LED kev daws teeb meem hauv kev siv tshuab teeb pom kev zoo yuav txuas ntxiv mus ntxiv rau yav tom ntej. Hauv kev teeb pom kev zoo, qhov no tau pom tseeb hauv ntau lub nroog, tab sis tus cwj pwm kuj tseem nyob hauv kev lag luam nce ntxiv thiab kev teeb tsa tsev. Txawm li cas los xij, ntawm no ib yam nkaus thiab ua kom pom tseeb tias muaj ob sab teeb thiab duab ntxoo.

Xyoo tsis ntev los no, nws tau pom meej tias dhau qhov ntsuas hluav taws xob hauv qhov tshwj xeeb sawv cev qhov teeb meem loj rau cov khoom siv hluav taws xob tsis zoo. Thawj lub tswv yim los ntawm daim teb lees qhov no. Piv txwv, lub nroog ntawm Esbjerg tau tshaj tawm tias kev tsis ua haujlwm loj tshaj plaws rau hnub dhau ntawm 400 txoj kev teeb pom kev vim muaj kev tawm tsam hluav taws xob. Qhov tshwj xeeb tshaj yog hais txog li Denmark yog ib tus xob laim pob cheeb tsam tsis zoo hauv tebchaws Europe.

Xob laim hluav taws xob tuaj yeem ncav cuag qhov tseem ceeb heev nyob ntawm qhov kev ncua deb ntawm qhov chaw nyob ze, thaj av thiab pob ntseg thiab lub teeb nrawm. Daim duab 1 qhia txog tus yam ntxwv zoo rau ntawm lub teeb pom kev ntawm cov teeb pom kev zoo tshwm sim los ntawm kev tsim lub zog ntawm lub teeb meem ntawm lub teeb hluav taws xob.

Thaum lub sijhawm hloov cov haujlwm hauv lub network, voltage peaks ntawm ntau txhiab volts raug tsim tawm, uas tawm los ntawm lub network hluav taws xob qis thiab thauj lwm cov khoom siv.

Ib qho piv txwv raug yog lub tripping ntawm fuses lossis sib xyaw sib txuas nrog LED thiab cov pa tawm tso hluav taws xob nrog cov pa ntawm cov pa, uas muab ob peb txhiab hluav taws xob ntawm lub txim hluav taws xob.

Kev siv hluav taws xob cov nqi hluav taws xob yog qhov tshwm sim tshwj xeeb tshaj yog nyob rau hauv rooj plaub ntawm Kev Tiv Thaiv chav kawm II Luminaires qhov twg them sib cais thiab tom qab ntawd qhov hluav taws xob siab ntawm lub teeb tsev teeb lossis cua sov ntawm cov LED. Qhov tshwm sim no yog qhov nyuaj rau txhua tus neeg tsav tsheb. leej twg, thaum nws grips nws lub tsheb, muaj peev xwm qee zaum tau txais hluav taws xob ceeb.

Tshwj xeeb cuam tshuam yog cov luminaires uas tau ua hauj lwm kiag li cais los ntawm lub ntiaj teb muaj peev xwm.

Mains yuam kev tuaj yeem ua rau qhov thiaj li hu overvoltages ib ntus. Txoj kev poob qis hauv nruab nrab ntawm tus neeg xyuas pib, piv txwv li vim yog kev puas tsuaj, yog qhov ua rau muaj feem ntau ntawm no. Nrog rau qhov kev txhaum no, cov voltage nominal tuaj yeem nce mus txog 400 V ntawm ntu vim qhov tseem ceeb asymmetries nyob rau hauv 3-theem pib. Cov kev tiv thaiv tiv thaiv overvoltages ib ntus yuav tsum tau tshwj xeeb xav.

Tab sis kuj tseem muaj teeb meem hauv lub tsev teeb thiab teeb pom kev zoo. Tshwj xeeb qhov twg overvoltages tsis xeeb los ntawm sab nraud, tab sis txhua hnub los ntawm tus kheej tsob ntoo. Hauv tshwj xeeb, cov xwm txheej tau paub los ntawm kev lag luam, uas tsim cov hluav taws xob ntau dhau ntawm cov khoom siv hluav taws xob thiab uas tau tshwm sim los ntawm cov xaim xaim xaim hluav taws xob tau mus txog lub teeb pom kev zoo. Thawj zaug tsis sib xws ntawm cov neeg luminaires lossis LEDs yog cov cim ntawm qhov no.

Raws li qhov kev paub dhau los no, dhau mus, luminaire cov tuam ntxhab tau ntsib lawv cov kev xav ua kom muaj zog ntawm cov luminaires tiv thaiv overvoltages. Lag luam lub zog ntawm cov luminaires txoj kev los tawm tsam overvoltages ntau xyoo dhau los. ntawm kwv yees li. 2,000 - 4,000 V, nws tam sim no nruab nrab kwv yees. 4,000 - 6,000 V.

Cov kev paub no tseem tau tshoov cov luminaire cov tuam txhab los tsa lawv cov kev xav tau ntawm luminaire lub zog tiv thaiv kev tawm tsam hluav taws xob. Xyoo ob peb xyoos dhau los lub zog ntawm txoj kev luminaires tiv thaiv overvoltages yog kwv yees li. 2,000 - 4,000 V, nws yog tam sim no kwv yees. 4,000 - 6,000 V ntawm qhov nruab nrab.

Txhawm rau coj qhov no mus rau hauv tus account, ntau lub luminaire tuam ntxhab muaj kev xaiv ntawm Luminaires nrog cov muaj zog hom 2 + 3 txheej tiv thaiv ntaus (SPD) los tiv thaiv lub ntiaj teb. Yog tias qhov no tsis tuaj yeem lossis tsis txhob txwm ua, piv txwv li vim tsis muaj chaw lossis vim tias cov luminaires twb tau teeb tsa rau hauv qhov chaw lawm, SPD kuj tseem tuaj yeem ntsia tau rau hauv lub mast fuse box. tuaj yeem siv tau. Qhov no tseem muaj qhov zoo ntawm cov kev saib xyuas yooj yim thiab rov kho dua. Ua kom tiav cov ntsiab lus tiv thaiv thiab nplij cov ntsiab lus teeb. Nws yuav tsum tau ntxiv nrog lub qhov sib txuas ntes cov najnpawb 1 + 2 hauv txoj kev hloov pauv / Lub chaw xa khoom nruab nrab tiv thaiv kev tshaj tawm ntawm xob laim ntawm cov xob laim thiab dhau kev tiv thaiv.

Hauv kev tsim cov kev pabcuam hauv tsev, kev tiv thaiv kev ua haujlwm zoo tuaj yeem ua tiav los ntawm kev nruab cov teeb tsa hluav taws xob nrog xob laim thiab kev tiv thaiv kev tiv thaiv. Piv txwv, ua ke nrog cov xob laim thiab cov neeg raug ntes ntau ntawm hom 1 + 2 tuaj yeem siv rau kev tiv thaiv tiv thaiv xob laim ntawm cov xob laim thiab qhov hloov pauv loj hauv kev tsim lub tshuab pub rau hauv, thiab SPD hom 2 + 3 lub teeb faib thawv thiab cov thawv ntim rau luminaires tuaj yeem siv rau kev tiv thaiv teb txuas thiab hloov overvoltages.

Kev tiv thaiv overvoltage tiv thaiv

Muaj ntau lub chaw tsim khoom rau cov kev tiv thaiv kom zoo rau lub khw. Yog li yuav tsum ua raws li cov ntsiab lus hauv qab no thaum xaiv cov cuab yeej tiv thaiv kev laus kom them nyiaj tshwj xeeb rau.

Kev tiv thaiv zoo overvoltage yuav tsum tau kuaj raws li IEC 61643-11 thiab qhov yuav tsum muaj VDE 0100-534. Yuav kom ua tiav qhov no, cov kev cai hauv qab no ntawm lwm tus tau ntsib cov xwm txheej teeb meem thiab cov khoom siv sib txuas tau txuas nrog hauv SPD.

Txij li SPD feem ntau tau muab zais rau ntawm qhov chaw tsis tau, piv txwv li hauv luminaires yog qhov teeb tsa, qhov ntsuas kom pom tseeb tsis yog qhov zoo tagnrho. SPD uas tseem tuaj yeem cuam tshuam lub luminaire ntawm lub rooj sib txig thaum muaj kev txhaum, cov yam ntxwv hauv qab no muaj nyob ntawm no txoj kev ua tau zoo thiab yooj yim ntawm kev taw qhia ncaj qha.
