Dab tsi yog ib qhochav tsev neeg siv khoom?
Lub tshuab hluav taws xob (consumer unit) yog dab tsi? Lub tshuab hluav taws xob no yog ib lub tshuab tseem ceeb hauv koj lub tsev, thiab nws yog lub tshuab uas tswj cov khoom siv hluav taws xob hauv koj lub tsev.
Nkag Siab Txog Chav Neeg Siv Khoom: Ib Feem Tseem Ceeb ntawm Lub Tshuab Hluav Taws Xob
Lo lus "lub thawv rau khaub ncaws" feem ntau yog hais txog hauv ntiaj teb ntawm cov tshuab hluav taws xob, tab sis ntau tus neeg yuav tsis nkag siab tag nrho nws lub ntsiab lus thiab kev ua haujlwm.Lub thawv rau khaub ncaws, tseem hu ua lub switchboard lossis lub thawv fuse, yog ib qho tseem ceeb hauv kev teeb tsa hluav taws xob hauv tsev thiab kev lag luam.Nws ua haujlwm ua lub hauv paus tseem ceeb rau kev tswj hwm hluav taws xob thiab kev faib tawm thoob plaws hauv lub tsev, kom ntseeg tau tias siv hluav taws xob tau zoo thiab muaj kev nyab xeeb.
Lub hauv paus tsim ntawm lub chaw faib hluav taws xob (PDU) yog los tiv thaiv cov hluav taws xob hauv lub tsev. Nws muaj cov cuab yeej hluav taws xob lossis fuses ua cov khoom siv kev nyab xeeb, tiv thaiv kev thauj khoom ntau dhau thiab luv luv uas yuav ua rau hluav taws xob kub hnyiab lossis ua rau cov khoom siv puas tsuaj. Yog tias muaj qhov txhaum, PDU yuav tua hluav taws xob cia li, ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv lub neej thiab khoom vaj khoom tsev.
Ib qho ntawm cov haujlwm tseem ceeb ntawm lub chaw faib hluav taws xob (PDU) yog faib cov hluav taws xob rau cov voj voog ib leeg hauv ib lub tsev.Txhua lub voj voog yog mob siab rau ib cheeb tsam lossis khoom siv tshwj xeeb, xws li teeb pom kev zoo, cua sov, lossis qhov hluav taws xob. Qhov kev faib tawm no tsis yog tsuas yog txhim kho kev nyab xeeb xwb tab sis kuj tso cai rau kev tswj hwm cov khoom siv fais fab zoo dua. Piv txwv li, yog tias lub voj voog raug overloaded, tsuas yog lub voj voog ntawd yuav tawg, thaum cov voj voog seem yuav txuas ntxiv ua haujlwm li qub.
Cov txheej txheem faib hluav taws xob niaj hnub no sawv cev rau kev txhim kho zoo dua li cov txheej txheem ib txwm muaj. Kev qhia txog cov khoom siv hluav taws xob seem (RCDs) tau hloov pauv kev nyab xeeb hluav taws xob. RCDs yog tsim los ntes cov hluav taws xob tsis sib npaug uas tuaj yeem qhia txog qhov ua yuam kev, xws li kev raug hluav taws xob tsis tau xav txog. Thaum pom, RCDs yuav txiav cov khoom siv hluav taws xob sai sai, txo qhov kev pheej hmoo ntawm kev raug hluav taws xob tsis tau xav txog. Yog li ntawd, ntau txoj cai tswjfwm kev tsim kho tam sim no xav kom muaj kev teeb tsa RCDs hauv cov txheej txheem faib hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv cov chaw muaj kev pheej hmoo siab xws li chav dej thiab chav ua noj.
Lwm yam tseem ceeb ntawm PDU yog nws ua raws li cov qauv hluav taws xob thiab cov cai. Hauv ntau lub tebchaws, kev teeb tsa hluav taws xob yuav tsum ua raws li cov lus qhia tshwj xeeb kom ntseeg tau tias muaj kev nyab xeeb thiab kev ntseeg siab. Cov PDUs yuav tsum tau teeb tsa los ntawm cov kws hluav taws xob tsim nyog uas paub txog cov cai no thiab xyuas kom meej tias lawv cov kev teeb tsa ua tau raws li cov kev xav tau hluav taws xob ntawm lub tsev. Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua ntawm PDU kuj tseem ceeb heev kom ntseeg tau tias kev ua haujlwm nyab xeeb txuas ntxiv mus.
Thaum xav txog kev txhim kho lossis hloov kho lub chaw faib hluav taws xob (PDU), yuav tsum xav txog ntau yam. Qhov loj ntawm lub chaw yuav tsum phim qhov xav tau ntawm lub tsev hluav taws xob. Cov tsev loj dua uas muaj ntau lub cuab yeej siv hluav taws xob yuav xav tau PDU uas muaj zog dua nrog ntau lub voj voog, thaum cov tsev me dua tsuas yog xav tau ib lub chaw yooj yim xwb. Ntxiv mus, qhov chaw ntawm PDU yog qhov tseem ceeb; nws yuav tsum yooj yim nkag mus rau kev saib xyuas thiab kaw thaum muaj xwm txheej ceev.
Thaum kawg, PDU yog ib qho tseem ceeb ntawm txhua lub tshuab hluav taws xob, ua kom muaj kev nyab xeeb, ua haujlwm tau zoo, thiab tswj tau kev faib hluav taws xob. Kev nkag siab txog nws txoj haujlwm thiab qhov tseem ceeb tuaj yeem pab cov tswv tsev thiab cov thawj coj vaj tse txiav txim siab txog lawv cov khoom siv hluav taws xob. Thaum thev naus laus zis txuas ntxiv mus, PDUs yuav pom kev tsim kho tshiab ntxiv, txhim kho lawv lub luag haujlwm hauv kev txhawb nqa kev nyab xeeb hluav taws xob thiab kev ua haujlwm tau zoo hauv lub neej txhua hnub. Txawm hais tias koj tab tom tsim lub tsev tshiab lossis hloov kho lub tshuab hluav taws xob uas twb muaj lawm, kev ua kom koj lub PDU hloov tshiab thiab ua raws li cov qauv tam sim no yog qhov tseem ceeb rau kev nyab xeeb thiab kev noj qab haus huv ntawm txhua tus neeg nyob hauv.
