Lub hnub ci DC Circuit Breaker: xyuas kom muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm cov tshuab hluav taws xob hnub ci
Raws li qhov kev thov rau lub zog rov ua dua tshiab txuas ntxiv mus, lub zog hnub ci tau dhau los ua ib qho kev xaiv tsim hluav taws xob nrov thiab ruaj khov. Cov tshuab hluav taws xob hnub ci siv lub zog hnub ci thiab hloov nws mus ua hluav taws xob siv tau, muab kev xaiv huv si, tsis muaj kev cuam tshuam rau ib puag ncig rau kev tsim hluav taws xob roj fossil ib txwm muaj. Txawm li cas los xij, kom ntseeg tau tias koj lub tshuab hluav taws xob hnub ci ua haujlwm tau zoo thiab muaj kev nyab xeeb, nws yog ib qho tseem ceeb uas yuav tsum siv cov khoom tsim nyog, xws li DC circuit breakers.
Lub tshuab hluav taws xob DC hnub ci, tseem hu ua lub tshuab hluav taws xob DC hnub ci, ua lub luag haujlwm tseem ceeb hauv kev nyab xeeb thiab kev ua haujlwm ntawm cov tshuab hluav taws xob hnub ci. Nws yog tsim los tiv thaiv lub tshuab los ntawm kev ua haujlwm ntau dhau thiab luv luv, yog li tiv thaiv kev puas tsuaj rau cov khoom siv thiab ua kom muaj kev nyab xeeb ntawm lub tshuab thiab nws cov neeg ua haujlwm. Tsis tas li ntawd, cov tshuab hluav taws xob DC pab cais cov khoom lossis cov ntu ntawm lub tshuab, ua rau yooj yim rau kev saib xyuas thiab daws teeb meem.
Ib qho ntawm cov haujlwm tseem ceeb ntawm DC circuit breaker hauv lub zog hnub ci yog los cuam tshuam cov dej ntws thaum muaj qhov txhaum lossis qhov xwm txheej tsis zoo. Qhov no tseem ceeb heev rau cov photovoltaic (PV) systems uas cov qib hluav taws xob DC siab heev. Los ntawm kev qhib lub voj voog sai sai thaum muaj qhov txhaum, DC circuit breakers pab txo qhov kev pheej hmoo ntawm hluav taws xob thiab lwm yam kev phom sij, tiv thaiv kev ncaj ncees ntawm koj lub hnub ci.
Ntxiv rau qhov kev xav txog kev nyab xeeb, kev siv DC circuit breakers tuaj yeem pab txhim kho qhov ua tau zoo thiab kev ntseeg siab ntawm koj lub zog hnub ci. Los ntawm kev muab ib txoj hauv kev los cais cov khoom tshwj xeeb ntawm lub cev, DC circuit breakers tso cai rau kev saib xyuas thiab kho kom tshwm sim yam tsis cuam tshuam rau tag nrho lub cev. Qhov no txo lub sijhawm tsis ua haujlwm thiab ua rau lub cev muaj zog ntau dua, thaum kawg ua rau muaj zog ntau dua thiab ua tau zoo dua.
Thaum xaiv lub DC circuit breaker rau lub zog hnub ci, nws yog ib qho tseem ceeb uas yuav tsum xav txog ntau yam kom ntseeg tau tias muaj kev sib raug zoo thiab kev ua haujlwm zoo tshaj plaws. Lub zog ntsuas thiab lub peev xwm tam sim no ntawm DC circuit breaker yuav tsum sib xws nrog cov lus qhia ntawm cov vaj huam sib luag hnub ci, inverter thiab lwm yam khoom ntawm lub kaw lus. Tsis tas li ntawd, DC circuit breakers yuav tsum tau tsim los kom tiv taus cov xwm txheej ib puag ncig uas feem ntau ntsib hauv kev teeb tsa hnub ci, suav nrog kev raug tshav ntuj, kev hloov pauv kub, thiab dej noo.
Tsis tas li ntawd xwb, kev teeb tsa thiab kev txuas hluav taws xob ntawm DC circuit breakers hauv cov tshuab fais fab hnub ci yuav tsum ua raws li cov qauv kev lag luam thiab cov kev coj ua zoo tshaj plaws los tswj kev nyab xeeb hluav taws xob thiab kev ua raws li txoj cai. Kev sau npe thiab kev kaw cov kev sib txuas DC breaker kom raug kuj tseem ceeb heev rau kev txheeb xyuas yooj yim thiab kev daws teeb meem yav tom ntej.
Hauv ntej, kev siv cov hluav taws xob DC hnub ci yog qhov tseem ceeb heev rau kev nyab xeeb, kev ntseeg siab thiab kev ua haujlwm zoo ntawm cov tshuab hluav taws xob hnub ci. Cov hluav taws xob DC ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov khoom siv thiab cov neeg ua haujlwm hauv kev teeb tsa hnub ci los ntawm kev muab kev tiv thaiv tiv thaiv overcurrent thiab luv luv. Tsis tas li ntawd, lawv lub peev xwm los cais cov khoom tsis zoo ntawm lub kaw lus ua rau kev saib xyuas thiab kho yooj yim, pab txhim kho kev ua haujlwm tag nrho thiab lub neej ntev ntawm lub tshuab hluav taws xob hnub ci. Thaum cov ntawv thov hnub ci txuas ntxiv nthuav dav, qhov tseem ceeb ntawm kev siv cov hluav taws xob DC zoo los pab txhawb kev xa tawm thiab kev ua haujlwm ntawm cov tshuab hluav taws xob hnub ci tsis tuaj yeem hais ntau dhau.
