Cov qauv hauv theem rau qhov siab hloov hluav taws xob
Apr 22, 2021
1. Txhawm rau kom muaj kev nyab xeeb ntawm kev saib xyuas cov neeg ua haujlwm thiab cov cuab yeej siv, txhua qhov hauv lub cheeb tsam uas yuav tsum muaj kev sib txuas lossis muab kev nkag mus yuav tsum tau ua ntej ua ntej, tsis suav cov cais lossis tshem tawm uas tuaj yeem nkag tau tom qab sib cais los ntawm lub siab- voltage hloov pauv.
2. Dedicated grounding conductors yuav tsum tau muab nyob rau hauv tag nrho ntev kev taw qhia kev ntawm txhua txhua high-voltage hloov txee. Yog tias nws yog tooj liab, qhov ceev tam sim no thaum lub hauv av txhaum yuav tsum tsis pub tshaj 200A / `mm ^ 2' Tus txheej txheem av yuav tsum tau nruab nrog lub davhlau ya nyob twg txuas nrog rau ntawm daim phiaj av, thiab yuav tsum muaj qhov cim tseg rau hauv av. Yog tias tus pib tswj kav hauv av tsis yog tooj liab, nws tseem yuav tsum ua kom tau raws li qhov xav tau ntawm tib lub ncov laus tiv thaiv tam sim no thiab luv luv-tam sim no.
3. Lub ncov tiv taus tam sim no thiab luv luv tiv thaiv tam sim no uas lub hauv hluav taws xob hauv av tuaj yeem tiv thaiv yuav tsum tsim nyog rau hauv Circuit Court loj. Tus pib tsaws hluav taws xob tshwj xeeb yuav tsum tiv taus qhov siab tshaj plaws luv luv-tam sim no uas yuav tshwm sim. Lub tsheb npav tsaws tsag thiab tus neeg xyuas pib txuas nrog rau nws yuav tsum tau xaiv tau tom qab dhau 87% ntawm cov ntsuas hluav taws xob luv luv tam sim no ntawm lub npe npog raws li cov qauv hauv Cov Lus Qhia B ntawm qhov xwm txheej no.
4. Lub hlau ncej ntawm lub tshuab hluav taws xob high-voltage hloov txee thiab cov hlau txhawb nqa ntawm qhov hluav taws xob hluav taws xob siab ntau qhov nruab rau hauv lub txee yuav tsum tau ua raws li cov kev ua haujlwm thiab khov kho thiab txuas nrog cov khoom lag luam tshwj xeeb hauv av.
5. Txhua qhov sib xyaw ua ke uas tuaj yeem muab cais tawm ntawm cov hluav taws xob tseem ceeb yuav tsum tau grounded, suav nrog hauv av los ntawm qhov hloov cov khoom siv hluav taws xob mus rau qhov chaw kaw ntawm lub pob hluav taws xob.
6. Raws li qhov xwm txheej ib txwm, cov hlau qhov uas yuav tsum tau muab tso rau hauv qhov chaw rho tawm yuav tsum muaj qhov sib txuas tau zoo nyob rau hauv cov kev mob uas tau hais tseg hauv qhov kev ntsuas, qhov chaw nyob tus kheej lossis pob txha lov (saib DL / T 486), thiab thaum lub chaw pabcuam tiv thaiv. nyob rau hauv ib txoj hauj lwm nruab nrab Thaum tsis kaw kiag li.
Qhov pib tshwj xeeb hauv av ntawm txhua qhov hluav taws xob high-voltage switchgear yuav tsum tau txuas nrog txhua qhov kev sib txuas thiab khov kho los ntawm cov chaw hais tshwj xeeb.
