Kev xaiv tus naj npawb tsim nyog ntawm tus ncej rau lub Circuit Court breaker yuav tsum muaj kev ntsuam xyuas zoo raws li cov khoom siv hluav taws xob hom, cov yam ntxwv ntawm kev thauj khoom, thiab cov cai tswj kev nyab xeeb. Lub hauv paus ntsiab lus tseem ceeb yog ua kom tiav kev tiv thaiv Circuit Court thiab kev saib xyuas zoo.
Cov naj npawb sib txawv ntawm tus ncej hauv Circuit Court breaker yog tsim rau cov xwm txheej tshwj xeeb; Kev xaiv tsis raug yuav ua rau muaj kev tiv thaiv tsis ua haujlwm lossis ua rau muaj kev pheej hmoo ntawm hluav taws xob poob siab. Cov hauv qab no yog cov tswv yim xaiv ncej categorized los ntawm daim ntawv thov scenario:
Residential Single-Phase System (220V) - Feem ntau pom muaj nyob hauv thaj chaw fais fab
1P (ib tug ncej)
Haum rau: Tsawg-hwj chim, tsis yog- cov khoom tseem ceeb xws li teeb pom kev zoo
Nta: Tsuas yog disconnects nyob hlau; cov hlau nruab nrab tseem txuas nrog. Tus nqi qis tab sis feem ntau qis dua kev nyab xeeb.
Ceeb Toom: Cov hlau nruab nrab tseem nyob thaum kho; yuav tsum tau ceeb toom ntxiv.
1P + N (ib leeg ncej + nruab nrab)
Tsim nyog rau: Cov qhov hluav taws xob zoo tib yam, qis - cov khoom siv hluav taws xob hluav taws xob
Nta: Disconnects ob lub nyob thiab nruab nrab nyob ntawm tej ib txhij. Compact thaiv, muab kev sib cais yooj yim.
2P (Double Ncej) Pom zoo rau cov keyboards tseem ceeb thiab cov hluav taws xob tseem ceeb
Haum rau: Main hloov, cua txias, dej rhaub, chav ua noj sockets
Qhov zoo: Ob lub xov hlau nyob thiab nruab nrab muaj ntau dhau thiab luv luv - tiv thaiv Circuit Court, ua tiav kev sib cais fais fab thiab kev saib xyuas zoo dua.
Standard Requirements: Hauv kev tsim vaj tsev niaj hnub no, lub ntsiab hloov yuav tsum siv 2P ncej kom tau raws li cov qauv kev nyab xeeb.
Txoj cai ntawm tus ntiv tes xoo: Teeb pom kev zoo siv 1P, lub qhov (socket) siv 1P + N lossis 2P, cov keyboards tseem ceeb thiab siab - cov khoom siv fais fab yuav tsum siv 2P.
Industrial Peb-Phase System (380V) - Siv rau lub cev muaj zog thiab cov cuab yeej tswj fais fab
3P (Peb-ncej)
Haum rau: Peb-theem sib npaug loads, xws li lub cev muaj zog, kiv cua, thiab twj tso kua mis.
Nta: Tswj peb nyob ntawm tej, dav siv nyob rau hauv industrial tis thawv thiab tswj txee.
Kev txwv: Tsis txhob cuam tshuam cov hlau nruab nrab; haum rau TN -C systems (PEN xaim yuav tsum tsis txhob raug txiav).
3P+N
Tsim nyog rau: Peb-theem plaub- cov kab hluav taws xob uas yuav tsum tau tswj xyuas qhov nruab nrab ntawm cov xaim hluav taws xob thaum tiv thaiv cov kab hluav taws xob theem.
Lus Cim: Tsuas yog peb txoj kab hluav taws xob nyob tau raug txiav; txoj kab nruab nrab txuas ntxiv mus, thiab ua tiav qhov nruab nrab ntawm qhov sib cais tsis tuaj yeem ua tiav.
4P (Plaub-ncej) Muaj feem xyuam rau cov hloov pauv tseem ceeb hauv cov tshuab tseem ceeb
Muaj feem xyuam rau: Cov khoom siv tseem ceeb hauv peb -theem plaub-wire systems
TN-S thiab TT grounding systems
Generator rau mains switching keyboards
Cov chaw uas muaj kev tsis txaus ntseeg tam sim no lossis cov kab nruab nrab tsis raug cai
Qhov zoo: Ib txhij tshem tawm tag nrho peb cov xov hlau nyob thiab cov xaim nruab nrab, tiv thaiv kev sib tsoo los ntawm cov hlau tsis huv thiab ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm tu.
Tus qauv tsim los ntawm: "Low-Voltage Power Distribution Design Code" qhia tias TT qhov chaw nkag mus yuav tsum yog 4P.
