Shenhai Explosion-Proof
Cov khoom tawg-pov thawj hluav taws xob yuav tsum muaj cov hlau casings uas yog hauv av. Ntxiv thiab, Kev sib txuas ntawm equipotential yog qhov tsim nyog los tiv thaiv qhov muaj peev xwm ntws tawm los ntawm kev rwb thaiv tsev tsis ua haujlwm thiab kom tsis txhob muaj kev pheej hmoo ntawm cov hluav taws xob hluav taws xob los ntawm cov hluav taws xob stray igniting explosive gas mixs..
Rau cov khoom siv zoo li no, grounding thiab equipotential bonding yuav tsum tau siv nyob rau hauv ib tug dual system, qhov twg txhua lub cuab yeej yog nruab nrog ob sab hauv thiab sab nraud grounding terminals. Cov terminals no yuav tsum tau khaws cia ntawm tib lub peev xwm thiab txuas nrog rau hauv av system los xyuas kom meej qhov ua tau zoo ntawm cov av thiab kev sib txuas.
Internal grounding yuav tsum tau teeb tsa nyob rau hauv cov kab txuas (junction box los yog lub ntsiab chamber), thiab sab nraud grounding yuav tsum tau nyob rau ntawm tus ntaus ntawv lub ntsiab casing. Qhov no ua kom ntseeg tau tias cov khoom siv hlau tseem ceeb, zoo li tus ncej, nyob rau tib lub peev xwm raws li hauv av.
Cov conductors siv rau grounding thiab equipotential bonding yuav tsum tau raws li ib tug tsawg kawg nkaus cross-sectional cheeb tsam, S. Nyob rau hauv ib theem tseem ceeb Circuit Court, yog tias qhov chaw hla ntu S0 tsis ntau tshaj 16mm², ces S yuav tsum tsawg kawg yog S0. Rau S0 ntawm 16mm² thiab 35mm², S yuav tsum yog 16 mm². Yog S0 tshaj 35mm², S yuav tsum ntau tshaj ib nrab ntawm S0. Yog S0 tsawg heev, Qhov tsawg kawg nkaus ntu ntu yuav tsum yog tsawg kawg 4mm².
Txhua qhov kev sib txuas hauv av thiab equipotential sib txuas yuav tsum ua kom muaj kev sib raug zoo ntawm cov neeg xyuas pib thiab cov khoom siv hauv av., nrog rau kev ntsuas los tiv thaiv loosening los yog corrosion.
Rau cov khoom siv hluav taws xob portable powered los ntawm daim phiaj, sab nraud grounding yuav bypassed, tab sis sab hauv av yuav tsum tau ua los ntawm kev siv lub cable nrog lub hauv paus hauv av. Yog hais tias powered los ntawm lub roj teeb pob nrog ungrounded ncej, grounding tsis tsim nyog. Ntxiv thiab, cov khoom siv hluav taws xob uas muaj ob chav los yog muaj zog rwb thaiv tsev yuav tsum tsis txhob muaj av.
