Circuit Court tej tog neeg nyob rau hauv Switchear yog cov tseem ceeb ntawm cov khoom siv tseem ceeb, siv cov khoom siv hluav taws xob thiab kab hauv kev sib tw dhau los, kev ncua luv lossis undervoltage. Nws yog qhov tsis tseem ceeb tswj hwm thiab kev tiv thaiv ntaus ntawv hauv zog. Ntawm no yog qhov ze saib:
I. Cov haujlwm theem pib ua haujlwm ntawm Circuit Court breaker
Ib txwm / tawm tswj
Los ntawm kev ua haujlwm ntawm tes los yog qhib lub Circuit Court breaker los ntawm kev ua haujlwm lossis khawm hloov mus rau kev sib txuas lossis txuas ntxiv ntawm Circuit Court.
Tsis siv neeg tswj: Sib tham nrog relays, theem {{l} xauv mus rau kom ua tiav cov chaw taws teeb lossis lub sijhawm tsis muaj kev ua haujlwm.
Txhaum Kev Tiv Thaiv Ua Haujlwm
Kev tiv thaiv ntau tshaj: Thaum cov tam sim no tshaj li tus nqi rated (piv txwv li lub caij nyoog rated tsis pub dhau 1 teev), lub Circuit Coffic tso tawm tau ua haujlwm, txiav tawm ntawm Circuit Court.
Luv - Circuit Court tiv thaiv: Thaum lub sijhawm luv luv ua rau muaj ntau qhov kev kub ntxhov tam sim no (ntau txog kev siv hluav taws xob tam sim no, feem ntau tsis pub dhau 0.1 vib nas this). Undervoltage tiv thaiv: Thaum cov hluav taws xob hluav taws xob hauv qab ib feem pua ntawm cov nqi rated tau ua kom tiv thaiv cov khoom siv los ntawm kev ua haujlwm qis thiab ua rau muaj kev puas tsuaj.
Kev tiv thaiv kev tiv thaiv (xaiv cov qauv): Cov qauv no tam sim no hauv Circuit Court thiab txiav tawm cov kab mob yog tias cov dej xau tshaj tawm (piv txwv li 30ma) kom tiv thaiv hluav taws xob.
ii. Lub luag haujlwm ntawm Circuit Court cov tog hauv Switchgear
Chaw Tswj Circuit Court Chaw
Hloov cov khoom siv yog qhov chaw tsim hluav taws xob "ntawm lub zog hluav taws xob raws li kev tswj hwm lub xeev ntawm lub xeev tseem ceeb ntawm thiab tawm, faib khoom thiab hloov fais fab.
Piv txwv li, hauv qhov qis - voltage Faib, cov tog hluav taws xob tuaj yeem tswj hwm lub zog ntawm cov ceg sib txawv kom tau raws li lub zog xav tau ntawm ntau cov khoom siv.
Cov Khoom Siv Tiv Thaiv Teeb Meem
Thaum cov khoom siv hauv qab (xws li cov khoom siv rau cov roj teeb, hloov pauv, thiab lwm yam) yog cov kev sib txuas lossis luv nrawm nrawm los tiv thaiv cov khoom siv puas tsuaj lossis hluav taws kub.
Thaum lub cev muaj zog pib, piv txwv li, qhov tam sim no tuaj yeem ncav cuag 5 mus rau 7 zaug nws cov nqi nyob. Circuit Court tej rooj txhoj tuaj yeem tiv taus short - lub sij hawm overload thiab zam kev yuam kev. Kev Nyab Xeeb Kev Nyab Xeeb Kev Nyab Xeeb Kev Nyab Xeeb System
Thaum kuaj xyuas lossis kev saib xyuas, cov neeg ua haujlwm nrog Circuit Court tuaj yeem ua rau tus kheej ua kom tiav cais tawm ntawm lub zog ntawm cov neeg ua haujlwm.
Piv txwv li, hauv high - voltage switchgear, kev tiv thaiv Circuit Court ua haujlwm nrog kev khiav tawm ntawm kev poob siab thiab qhib thiab kaw thiab kaw thiab kaw thiab kaw thiab kaw hauv qab load).
III. Hom thiab kev faib tawm ntawm Circuit Court Shripers
Los ntawm voltage
Tsawg 'cov hluav taws xob hluav taws xob tsawg dua: ntsuas hluav taws xob tsawg dua lossis sib npaug ntawm 1kv (piv txwv li AC 400v, DC 800V, DC 800V, DC 800V, DC 800V, DC 800V, DC 800V, DC 800V, DC 800V, DC 800V, DC 800V, DC 800V, DC 800V, DC 800V, DC 800V) rau kev tswj hwm lub tsev, kev tswj hwm, thiab lwm yam.
High voltage Circuit Charterters: ntsuas voltage ntau dua 1kv (piv txwv li} kv, 35kv, 110kv) rau cov khoom siv hluav taws xob siab, hloov chaw, thiab lwm yam, thiab lwm yam.
Los ntawm cov qauv hom

Haum rau kev siv cov ntawv thov nruab nrab (piv txwv li . 10 A-1600A) xws li kev xa tawm thiab ua lag luam teeb pom kev zoo thiab ua lag luam.
Nws yog kev cog lus, qis {{{0} Tus nqi siv tus nqi, tab sis kuj yooj yim tiv thaiv.
Tej yam me me Circuit Court breaker (MCB):
Haum rau cov ntawv thov tam sim no xws li 1A-125A, xws li faib khoom hauv tsev thiab cov khoom siv tiv thaiv kev ua haujlwm.
Nws yog kev cog lus thiab tuaj yeem suav nrog kev tiv thaiv to furnage (piv txwv, RCD).
Los ntawm arc extinguishing nruab nrab:
Cua Circuit Court breaker: Siv cua raws li arc extinguishing nruab nrab, cov qauv yooj yim, tus nqi qis, tab sis txwv crushing muaj peev xwm.
Lub tshuab nqus tsev hluav taws xob: Siv lub siab insulation zog zog ntawm lub tshuab nqus tsev mus rau qhov hluav taws xob tua hluav taws (piv txwv li, 10kv-35kv), muaj lub neej ntev.
SF6 Circuit Court Breaker: Kev siv Sulphur Hexafluoride (SF6) roj mus rau Ultra- qhov kev siv siab siab (piv txwv li saum 110Kv). Txawm li cas los xij, txawm li cas los xij, yog lub zog tsev cog khoom roj uas yuav tsum muaj kev kho mob tshwj xeeb. IV. Taw qhia Ntsiab Lus Cov Qauv Tsis Muaj Cov Circuit Court
Nyob tam sim no: Qhov nyiaj siab tshaj plaws tau tso cai ntws los ntawm kev ua txhaum Circuit Circuit Court nyob ntev. Cov ntsuas no yuav tsum tau xaiv raws li lub nra tam sim no (piv txwv li, 1.2-1.5 zaug lub cev muaj zog tam sim no ntawm lub cev muaj zog).
Kev ntsuas hluav taws xob: Qhov ntsuas hluav taws xob ntawm qhov uas ib qho Circuit Court breaker ib txwm ua haujlwm. Qhov ntsuas no yuav tsum phim lub kaw lus system (piv txwv li, AC 400v, DC 110V).
Crushing muaj peev xwm (ICU / ICS):
Qhov kawg breaking muaj peev xwm (ICU: Qhov siab tshaj plaws luv - Circuit Racuit tam sim no (piv txwv li Ka) tias lub Circuit Court breaker yuav muaj kev ruaj ntseg.
Kev pabcuam hluav taws xob muaj peev xwm: Lub peev xwm ntawm Circuit Court breaker mus txuas ntxiv ua haujlwm tom qab kev cuam tshuam luv nqi tam sim no (feem ntau 50% -100%% ICU).
Kev Pab Lub Neej: Neeg kho tshuab lub neej (piv txwv li {{1} Kev cuam tshuam nrog hluav taws xob thiab qhib kev cuam tshuam hluav taws xob) yuav tsum muaj raws li kev cai thov.
V. Circuit Court xaiv xaiv thiab kev thov ua piv txwv
Xaiv cov ntsiab cai
Load Mattering: Xaiv cov rated tam sim no ntawm Circuit Court breaker raws li cov ntsuas tam sim no ntawm lub ntaus ntawv thiab pib tam sim no. Kev Tiv Thaiv Kev Tiv Thaiv: Up -}} {} Txoj Kev Ua Haujlwm Qib Circuit Court (piv txwv li Circuit Court Circuit Court yuav tsum ua haujlwm ntev dua li Cegruit Court breaker).
Kev hloov kho ib puag ncig: Circuit Court tej kev pab cuam nrog kev tiv thaiv kev tiv thaiv siab (piv txwv li IP65) yuav tsum tau siv hauv qhov chaw kub, noo noo.
Cov Khoom Siv Thov
Cov ntaub ntawv centre zog faib: Siv cov kev sib txuas ua ke raws li lub tsheb sib tshooj tseem ceeb, cov kev tiv thaiv tsis sib xws, kom qhov txuas ntxiv ntawm cov khoom siv fais fab.
Lub thawv faib khoom: Tej zaum cov kev sib cais me me (MCB) ua ke nrog cov cuab yeej tam sim no (RCD) muab kev tiv thaiv Cegrcuit Courload thiab tus kheej kev poob siab.
Txuas txuas dua lub zog hluav taws xob: Highverctage nqus hluav taws xob breakcuit Court yog siv rau kev tswj cov kab ke thiab cua ua liaj ua teb kom nrawm nrawm thiab lwm yam khoom siv.
