Installation Specifications rau Distribution Boxes

Cov kev qhia tshwj xeeb ntawm lub thawv xa khoom yog ntau-faceted thiab ntau- tus qauv. Lub hom phiaj tseem ceeb yog ua kom muaj kev nyab xeeb ntawm lub zog hluav taws xob thiab kev nyab xeeb ntawm cov neeg ua haujlwm. Cov nram qab no yog lub ntsiab installation specifications rau siv:

I. Kev teeb tsa qhov siab thiab ib puag ncig yuav tsum tau ua
1. Txoj cai ntawm txoj haujlwm:
Nws yuav tsum nyob ze rau ntawm qhov chaw thauj khoom los pab txhawb kev ua haujlwm, kev saib xyuas thiab tshuaj xyuas, thiab yuav tsum tsis txhob muab tso rau hauv qhov chaw uas cuam tshuam rau kev khiav tawm ntawm cov neeg ua haujlwm thiab muaj kev sib tsoo lossis kev vibration hnyav.

2. Qhov siab tus qauv:
Pem teb- hom sawv: Hauv qab ntawm lub thawv yuav tsum yog 100mm ~ 200mm siab tshaj hauv av, feem ntau yog ua los ntawm cov pob zeb hauv paus lossis steel puag.

Phab ntsa-mounted:
Lub thawv teeb pom kev zoo: Lub npoo hauv qab ntawm lub thawv yog feem ntau 1.5 meters txog 1.8 meters los ntawm hauv av, thiab qhov sib nrug deb yog 1.5 meters, uas yooj yim rau kev khiav lag luam.
Meter box: Feem ntau qhov chaw nruab nrab yog 1.6 meters mus rau 1.8 meters deb ntawm lub hauv av, uas yooj yim rau kev nyeem ntawv 'meter'.
Yog tias tsis muaj qhov tshwj xeeb uas yuav tsum tau ua, nws yog qhov tsim nyog rau qhov chaw nruab nrab ntawm lub thawv kom txog li 1.6 meters los ntawm hauv av.

Embedded: Rau cov thawv ntim rau hauv phab ntsa, lub vaj huam sib luag yuav tsum nyob ze rau ntawm phab ntsa, thiab cov qhov khoob nyob ib puag ncig yuav tsum tau ntim nrog mortar, tab sis lub thawv yuav tsum tsis txhob raug nyem los yog deformed.

3. Ib puag ncig tej yam kev mob:
Tsis muaj hluav taws kub, tawg, corrosive gas lossis plua plav, tsis muaj plua plav ua paug.
Qhov ntsuas kub nyob ib puag ncig feem ntau tsis tshaj 40 degree, thiab cov av noo yuav tsum tsis txhob siab dhau.
Nws yog nruj me ntsis txwv tsis pub rau nruab nws nyob rau hauv chav dej zones 0 thiab 1 los yog nyob rau hauv ib tug ntub qhov chaw nws yuav ua rau condensation. Yog tias nws yuav tsum tau muab tso rau hauv qhov chaw ntub dej, yuav tsum tau siv lub thawv ntim khoom pov thawj uas tsis muaj dej tsawg dua IP54.

II. Enclosure thiab Component Requirements

1. Cov ntaub ntawv pov thawj:Lub thawv xa khoom yuav tsum yog ua los ntawm txias- dov steel phaj nrog lub thickness Ntau dua los yog sib npaug li 1.5 hli los yog nplaim taws- cov khoom siv insulating retardant.

2. Cov Txheej Txheem Txheej Txheem:Cheebtsam yuav tsum tau mounted rau ntawm hlau los yog nplaim taws- retardant insulating boards; Circuit Court breakers yuav tsum muaj insulating partitions ntawm theem, thiab nthuav tawm nyob rau hauv yuav tsum muaj daim hlau tiv thaiv.

3. Enclosure Function:Cov ntaub thaiv npog yuav tsum tsis muaj nag thiab plua plav, thiab qhov ntsuas IP tiv thaiv yuav tsum ua tau raws li qhov xav tau ntawm ib puag ncig.

III. Kev Siv Hluav Taws Xob Hluav Taws Xob thiab Kev Siv Hluav Taws Xob

1. Kev tiv thaiv hauv av:Cov hlau enclosure, mounting phaj, thiab hlau casing yuav tsum muaj kev ntseeg siab hauv av los ntawm PE davhlau ya nyob twg thaiv. Lub qhov rooj kaw yuav tsum tau txuas nrog daj / ntsuab bicolor mos tooj liab hlau.

2. N thiab PE Kab:Ib qho N- kab davhlau ya nyob twg thiab PE- kab davhlau ya nyob twg thaiv yuav tsum tau muab tso rau hauv lub thawv. Lub N-kab davhlau ya nyob twg thaiv yuav tsum tau insulated los ntawm cov hlau mounting phaj.

3. Hlau Specifications:Kev sib txuas ntawm cov xov hlau yuav tsum siv cov xov tooj tooj liab, xim - coded raws li cov qauv: L1 daj, L2 ntsuab, L3 liab, N lub teeb xiav, thiab PE daj-ntsuab.

4. Cable Inlet / Qhov hluav taws xob:Cable inlets / outlets yuav tsum nyob rau hauv qab ntawm lub enclosure. Insulating lub tes tsho yuav tsum tau muab ntsia rau ntawm cov kav dej, thiab lub taub hau cable yuav tsum ruaj ruaj. N thiab PE xov hlau los ntawm ntau lub voj voog yuav tsum tsis txhob txuas rau tib lub qhov ntawm lub davhlau ya nyob twg thaiv.
