Shenhai Explosion-Proof
Txhawm rau kom muaj kev nyab xeeb thiab siv tau zoo ntawm LED tawg-pov thawj teeb, Nws yog ib qho tseem ceeb uas yuav tau xav txog cov ntsiab lus hauv qab no thaum xaiv cov xaim hluav taws xob:
1. Xaiv qhov chaw:
Lub Circuit Court yuav tsum nyob rau hauv cov cheeb tsam uas muaj qhov tsawg dua qhov kev pheej hmoo tawg lossis nyob deb ntawm qhov chaw ntawm qhov hluav taws kub.
2. Txoj kev xaim:
Hauv qhov chaw tawg, Cov txheej txheem tseem ceeb ntawm kev siv hluav taws xob muaj xws li kev siv hluav taws xob tawg-pov thawj steel conduits thiab cable thaiv.
3. Kev rho tawm thiab sealing:
Rau circuits thiab cov kav dej tiv thaiv, kab, los yog cov kav dej hlau hla cov phab ntsa los yog cov slabs sib cais sib txawv ntawm kev phom sij tawg, Cov ntaub ntawv uas tsis yog-combustible yuav tsum tau siv rau nruj sealing.
4. Kev xaiv cov khoom siv coj los siv:
Rau thaj chaw categorized nyob rau hauv explosion txaus ntshai theem 1, tooj liab hlau los yog cables yuav tsum tau siv. Hauv cov xwm txheej uas muaj kev vibrations hnyav, ntau txoj hlua tooj liab tub ntxhais cables lossis cov xov hlau raug pom zoo. Aluminium core fais fab cables tsis haum rau underground coal mines.
Nyob rau hauv explosion txaus ntshai theem 2 ib puag ncig, Cov kab hluav taws xob yuav tsum tau ua los ntawm txhuas cov xov hlau lossis cov kab hluav taws xob uas muaj qhov sib txawv ntawm thaj tsam ntau dua 4mm², thiab cov teeb pom kev zoo yuav tsum muaj thaj tsam ntawm 2.5mm², muab tso rau saum lub aluminium cores los yog cables.
5. Muaj peev xwm nqa tau tam sim no:
Rau thaj tsam 1 thiab 2, cov kev xaiv hla ntu ntawm cov kab hluav taws xob thiab cov kab hluav taws xob yuav tsum muaj lub peev xwm conductive tsis tsawg dua 1.25 lub sij hawm qhov ntsuas tam sim no ntawm lub fuse thiab qhov teeb tsa tam sim no ntawm lub sij hawm ntev overcurrent tso tawm ntawm Circuit Court breaker.
Qhov tso cai tam sim no muaj peev xwm rau ceg circuits ntawm qis-voltage squirrel tawb asynchronous motors yuav tsum tsis txhob tsawg dua. 1.25 lub sij hawm qhov ntsuas tam sim no ntawm lub cev muaj zog.
6. Hluav taws xob Circuit Court Connections:
1. Cov kev sib txuas nruab nrab ntawm circuits hauv cheeb tsam 1 thiab 2 yuav tsum nyob ze ntawm qhov tawg-pov thawj hlws ris los yog kev sib txuas cov thawv sib haum nrog qhov chaw muaj kev phom sij. Zone 1 yuav tsum tau siv cov thawv ntawv flameproof, thaum zone 2 tuaj yeem siv tau nce kev nyab xeeb hom junction boxes.
2. Yog tias aluminium core cables lossis cov xov hlau raug xaiv rau thaj tsam 2 circuits, cov kev sib txuas yuav tsum txhim khu kev qha kom yooj yim installation thiab txij nkawm los ntawm cov neeg siv.
Cov kev taw qhia no yog txhawm rau pab xaiv cov kab tsim nyog rau kev txhim kho LED tawg-pov thawj teeb, kom ntseeg tau tias muaj kev nyab xeeb thiab kev ua haujlwm.
