Ntawm -Site Requirements for Distribution Box Installation

Raws li lub zog faib hluav taws xob, kev teeb tsa ntawm lub thawv xa khoom yuav tsum tau teeb tsa hierarchically -tshwj xeeb nyob rau hauv cov kab ke ntawm cov thawv xa khoom loj, cov thawv xa khoom thib ob, thiab cov thawv hloov pauv- yog li tsim kom muaj peb tus qauv -tier faib qauv. Kev tsim kho vaj tse yuav tsum ua raws li cov qauv kos duab engineering. Tsis tas li ntawd, nyob rau ntawm - qhov chaw tso chaw ntawm cov thawv xa khoom thiab cov thawv hloov pauv yuav tsum tau muab faib ua kom muaj txiaj ntsig: lub thawv xa khoom loj yuav tsum nyob ze ze rau lub tshuab hloov hluav taws xob lossis lub zog hluav taws xob sab nraud los pab txhawb lub zog nkag, thaum lub thawv xa khoom thib ob yuav tsum tau teeb tsa ze ntawm lub hwj chim- siv cov khoom siv lossis thaj chaw uas muaj cov khoom hnyav kom ntseeg tau qhov sib npaug ntawm peb{{7}. Hloov lub thawv yuav tsum tau muab tso rau ze li sai tau rau cov ntsiab lus ntawm kev siv hluav taws xob, raws li cov xwm txheej tshwj xeeb ntawm qhov chaw tsim kho.

 

Hais txog lub zog hluav taws xob rau ob qho tib si lub zog thiab teeb pom kev zoo ntawm qhov chaw tsim kho, yuav tsum tau tsim ob qhov hluav taws xob sib txawv; yog li ntawd, cov thawv ntim khoom sib cais yuav tsum raug xaiv rau lub zog thiab lub teeb pom kev zoo.

 

Txhua lub thawv xa khoom yuav tsum tau nruab nrog lub ntsiab disconnector, ceg Circuit Court disconnectors, lub ntsiab fuse, thiab ceg Circuit Court fuses; qhov ntsuas qhov muaj peev xwm ntawm cov cuab yeej hloov pauv tseem ceeb thiab cov cuab yeej hloov pauv yuav tsum tau ua kom zoo sib xws.

 

Residual Current Devices (RCDs) uas ua raws li cov qauv tsim yuav tsum tau muab tso rau hauv lub thawv xa khoom, feem ntau nyob rau sab load ntawm lub ntsiab fais fab disconnector. Cov thawv ntim khoom thiab cov thawv hloov pauv yuav tsum tau khaws cia tsis muaj lwm yam khib nyiab thiab khaws cia rau hauv qhov chaw huv si; Kev sib txuas ntawm cov khoom siv hluav taws xob tsis raug cai lossis ib ntus raug txwv nruj heev. Yog tias kev ua haujlwm tsis ua haujlwm rau lub sijhawm ntev tshaj li ib teev, cov thawv tsim khoom yuav tsum raug kaw kom ruaj ntseg rau kev tiv thaiv.
