Tus Tiv Thaiv Surge Puas Yuav Ua Haujlwm Tsis Muaj Av?
Lub tshuab tiv thaiv hluav taws xob tsis ua haujlwm zoo yog tsis muaj kev sib txuas hauv av. Yog xav kom muaj kev tiv thaiv tiag tiag los ntawm kev nce siab ntawm lub zog hluav taws xob, xyuas kom koj lub qhov hluav taws xob tau sib txuas hauv av thiab koj cov xov hlau tau ua raws li tus qauv.
Vim li cas koj lub tshuab tiv thaiv xob laim tsuas yog ib nrab tiav yam tsis muaj kev tiv thaiv sab hauv?
Ib lub cuab yeej tiv thaiv hluav taws xob ntau theem (SPD) ua haujlwm los ntawm ntau theem kev hloov pauv zog thiab cov txheej txheem clamping voltage. Hauv nws lub hauv paus, nws siv cov khoom xws li MOVs thiab GDTs kom hloov pauv lub zog hluav taws xob mus rau hauv av sai sai thiab clamp lub zog seem hauv cov kev txwv kev nyab xeeb rau cov khoom siv txuas nrog. Nws qhov ua tau zoo nyob ntawm qhov zoo ntawm cov khoom, qhov ntev ntawm cov hlau lead hauv av, thiab kev tiv thaiv txheej txheem sib koom ua ke. Cov cim qhia kev ua tau zoo tseem ceeb (KPIs) xws li clamping voltage (Up) thiab surge lub neej voj voog ua kom ntseeg tau tias muaj kev ntseeg siab mus sij hawm ntev.
Phau Ntawv Qhia Yuav Khoom Siv Tiv Thaiv Hluav Taws Xob: 3 Lub Tswv Yim Ntse Kom Xaiv Qhov Tseeb
Tshawb nrhiav seb yuav xaiv cov khoom siv tiv thaiv hluav taws xob (SPD) li cas los ntawm kev soj ntsuam cov txheej txheem tsim khoom, daim ntawv pov thawj, thiab kev kuaj hauv chaw kuaj mob - qhov tseem ceeb rau kev nyab xeeb ntawm lub tshuab hluav taws xob.
Kev Tiv Thaiv Xob laim Sab Hauv thiab Cov Khoom Siv Surge: Qhov Txawv Yog Dab Tsi?
Kev tiv thaiv xob laim sab hauv tsom mus rau kev tiv thaiv cov hluav taws xob txaus ntshai uas tshwm sim los ntawm cov hluav taws xob xob laim, feem ntau yog los ntawm kev sib txuas ua ke thiab kev rwb thaiv tsev. Kev tiv thaiv hluav taws xob siab lub hom phiaj yog tiv thaiv cov kab ke sab hauv los ntawm kev siv hluav taws xob siab los ntawm kev siv cov SPDs sib koom ua ke, kev tiv thaiv, kev sib txuas av, thiab cov txheej txheem cais tawm. Cov koob IEC 62305 qhia meej txog ob lub tswv yim no, nrog SPM daws cov teebmeem hluav taws xob siab thiab LPS sab hauv daws cov kev pheej hmoo hluav taws xob siab. Ua ke, ob qho tib si yog cov khoom tseem ceeb ntawm kev tiv thaiv xob laim tiav.
Kev Xaiv Cov Khoom Siv Tiv Thaiv Surge rau PV Systems - SPDs Parameter
Tsab xov xwm no piav qhia txog yuav ua li cas xaiv cov SPDs zoo rau sab DC ntawm cov tshuab hluav taws xob hnub ci ru tsev, hais txog qhov xav tau cov khoom siv PV tshwj xeeb nrog cov ntsuas hluav taws xob thiab tam sim no kom raug. Nws kuj taw qhia tias cov nqi txheem tsuas yog qhov tsawg kawg nkaus xwb, yog li kev teeb tsa lub kaw lus, kev sib txuas hauv av, thiab kev tiv thaiv xob laim yuav tsum tau ua tib zoo xav txog.
Yuav Ua Li Cas Xaiv Ib Lub Khoom Siv Tiv Thaiv Surge (SPD) Kom Yog
Kev xaiv SPD yuav tsum tau muaj kev ntsuam xyuas tag nrho ntawm qhov hluav taws xob ntawm lub kaw lus, kev pheej hmoo ntawm xob laim, lub peev xwm tiv taus cov khoom siv, thiab ib puag ncig kev teeb tsa.
Kev Xaiv Cov Khoom Siv Tiv Thaiv Surge rau PV Systems - SPDs Installation
Kev tsim hluav taws xob photovoltaic (PV) yog qhov tseem ceeb ntawm lub zog rov ua dua tshiab thiab nws tab tom sib tw ntau dua li kev tsim hluav taws xob ib txwm muaj los ntawm kev lag luam. Ntawm ntau hom kev siv PV, cov kab ke me me faib tawm - xws li kev teeb tsa PV saum ru tsev - yog qhov siv dav tshaj plaws.
Tsib Txoj Kev Tiv Thaiv ntawm Cov Khoom Siv Tiv Thaiv Surge
Kwv yees li ntawm 75% ntawm cov khoom siv hluav taws xob ua tsis tau zoo yog los ntawm kev hloov pauv sai sai thiab kev nce siab. Cov hluav taws xob hloov pauv sai sai thiab kev nce siab yog qhov muaj nyob txhua qhov chaw - txawm tias los ntawm cov hluav taws xob, xob laim ntaus, tawg, lossis txawm tias kev taug kev saum daim ntaub pua plag, uas tuaj yeem tsim kaum txhiab volts ntawm electrostatic induction. Cov no yog cov kev hem thawj uas tsis pom tab sis tuag taus rau cov khoom siv hluav taws xob.
Yog li ntawd, txhawm rau txhim kho kev ntseeg siab ntawm cov khoom siv hluav taws xob thiab xyuas kom meej tias tib neeg muaj kev nyab xeeb, yuav tsum muaj kev tiv thaiv kev hloov pauv hluav taws xob thiab kev nce siab.
Kev Xaiv Cov Khoom Siv Tiv Thaiv Surge Kev Xaiv rau PV Systems - Hom SPDs
Cov tshuab PV saum ru tsev muaj ob qho tib si AC thiab DC fais fab faib, nrog rau cov voltages ncav cuag 1500V. Tshwj xeeb, sab DC—xws li PV panels—tej zaum yuav raug ncaj qha rau thaj chaw uas yuav raug xob laim ntaus, ua rau lawv yooj yim raug hluav taws xob puas tsuaj. Txawm tias cov PV modules tsis raug kev puas tsuaj los ntawm kev rwb thaiv tsev nyob rau hauv qhov hluav taws xob overvoltage los ntawm xob laim, lawv cov kev ua haujlwm hluav taws xob tseem yuav poob qis. Qhov no ua rau muaj kev xav tau ntau dua rau kev tiv thaiv overvoltage rau cov tshuab PV saum ru tsev.
