Cov ntaub ntawv hauv av thiab cov kev cai yooj yim ntawm cov tshuab hluav taws xob qis hluav taws xob
Txhawm rau koom tes nrog cov cuab yeej tiv thaiv xob laim xws li cov cuab yeej tiv thaiv hluav taws xob hauv cov tshuab hluav taws xob qis kom tso tawm hluav taws xob, cov hauv av hauv cov tshuab hluav taws xob tsawg hluav taws xob yuav tsum ua raws li cov hauv qab no:
1. Cov ntaub ntawv hauv av ntawm qhov qis qis tuaj yeem muab faib ua peb hom: TN, TT, thiab IT. Ntawm lawv, TN system tuaj yeem muab faib ua peb hom: TN-C, TN-S thiab TN-C-S.
2. Daim ntawv hauv av ntawm lub tshuab hluav taws xob qis hluav taws xob yuav tsum tau txiav txim siab raws li cov kev cai tshwj xeeb ntawm kev tiv thaiv hluav taws xob kev nyab xeeb ntawm lub cev.
3. Thaum cov kev tiv thaiv hauv av thiab kev ua haujlwm hauv av sib koom tib yam khoom siv hauv av, cov kev cai tsim nyog rau kev tiv thaiv hauv av yuav tsum tau ntsib ua ntej.
4. Cov khoom siv hluav taws xob nthuav tawm ntawm cov khoom siv hluav taws xob yuav tsum tsis txhob siv los ua cov kab sib txuas sib txuas rau kev tiv thaiv lub ntiaj teb conductors (PE).
5. Tus neeg xyuas pib tiv thaiv lub ntiaj teb (PE) yuav tsum ua raws li cov cai hauv qab no:
1.Lub ntiaj teb tiv thaiv tus neeg xyuas pib (PE) yuav tsum muaj kev tiv thaiv tsim nyog tiv thaiv kev puas tsuaj, tshuaj lom neeg lossis hluav taws xob puas tsuaj, electrodynamic thiab thermal cuam tshuam, thiab lwm yam.
2. Cov khoom siv tiv thaiv hluav taws xob thiab cov khoom siv hloov pauv yuav tsum tsis txhob muab tso rau hauv qhov hluav taws xob tiv thaiv hluav taws xob (PE) Circuit Court, tab sis cov ntsiab lus txuas uas tsuas yog cuam tshuam nrog cov cuab yeej raug tso cai.
3.Thaum siv cov khoom siv hluav taws xob saib xyuas hauv av, cov khoom tshwj xeeb xws li kev ua haujlwm sensors, coils, tam sim no transformers, thiab lwm yam.
4. Thaum tus neeg xyuas pib tooj liab txuas nrog txhuas tus neeg xyuas pib, yuav tsum siv cov khoom sib txuas tshwj xeeb rau tooj liab thiab txhuas.
6. Qhov chaw hla ntawm qhov chaw tiv thaiv hauv av (PE) yuav tsum ua kom tau raws li cov kev cai rau kev siv hluav taws xob tsis siv neeg txiav tawm tom qab luv luv Circuit Court, thiab tuaj yeem tiv taus cov neeg kho tshuab kev ntxhov siab thiab thermal cuam tshuam los ntawm qhov kev cia siab tam sim no nyob rau hauv kev txiav- tawm lub sijhawm ntawm cov khoom siv tiv thaiv.
7. Qhov tsawg kawg nkaus qhov chaw hla ntawm qhov sib cais nteg tus neeg tiv thaiv lub ntiaj teb (PE) yuav tsum ua raws li cov cai ntawm Tshooj 7.4.5 ntawm tus qauv no.
8. Tus neeg xyuas pib tiv thaiv lub ntiaj teb (PE) yuav muaj ib lossis ntau dua ntawm cov khoom hauv qab no:
1.Conductors nyob rau hauv multi-core cables
2.Insulated los yog liab qab conductors koom nrog nyob conductors
3.Bare los yog insulated conductors rau taag installation
4.Metal cable tsho thiab concentric conductor fais fab cables uas ua tau raws li dynamic thiab thermally ruaj khov hluav taws xob txuas ntxiv
9. Cov hlau hauv qab no yuav tsum tsis txhob siv los ua cov khoom tiv thaiv hauv ntiaj teb (PE):
1. Hlau kav dej
2. Cov kav hlau uas muaj roj, kua, hmoov, thiab lwm yam.
3.Slexible lossis bendable hlau conduit
4.Slexible hlau qhov chaw
5. Kev them nyiaj yug hlau, cable tais, hlau tiv thaiv conduit
