Shenhai Explosion-Proof
Tawg-prof hluav taws xob khoom yuav tsum muaj hlau casings uas yog grounded. txuas ntxiv, equipotential bonding yog tsim nyog los tiv thaiv tej leakage tam sim no vim insulation tsis ua hauj lwm thiab kom tsis txhob muaj hluav taws xob sparks ntawm stray tam sim no igniting explosive roj mixtures.
Rau tej khoom siv, Av thiab equipotential bonding yuav tsum tau DVR nyob rau hauv ib lub cev dual, Qhov twg txhua ntaus ntawv yog nruab nrog ob leeg thoob ntiaj teb thiab lwm grounding terminals. Cov davhlau ya nyob twg yuav tsum khaws cia tib yam thiab txuas nrog rau qhov hauv pem teb Lawv yuav xyuas kom meej tias cov zoo ntawm hauv pem teb thiab bonding.
Internal grounding yuav tsum tau teeb nyob rau hauv lub wiring compartment (hlws ris lub thawv los yog lub ntsiab chamber), Thiab lwm grounding yuav tsum tau nyob rau ntawm tus ntaus ntawv lub ntsiab casing. Qhov no xyuas kom meej tias tus ntaus ntawv loj hlau components, ncej, Tib yam li hauv pem teb.
Tus cwjpwm siv rau hauv pem teb thiab equipotential bonding yuav tsum tau ntsib ib cheeb tsam tsawg kawg nkaus-seem, S. Nyob rau hauv ib theem ib zaug xwb circuit Court, Yog hais tias tus ntoo khaub lig-seem S0 tsis pub tshaj 16m², Ces yuav tsum muaj tsawg kawg yog S0. Rau S0 ntawm 16m² thiab 35mm², Yuav tsum muaj 16mm². Yog hais tias S0 tshaj 35mm², Yuav tsum tau ntau tshaj ib nrab ntawm S0. Yog hais tias S0 yog ib qho me me, Qhov tsawg kawg nkaus yuav tsum muaj tsawg kawg yog 4mm².
Txhua grounding thiab equipotential bonding ntaus ntawv yuav tsum xyuas kom txhim khu kev qha ntawm tus cwjpwm thiab hauv pem teb terminals, kev ntsuas los tiv thaiv loosening los yog corrosion.
Rau portable hluav taws xob li powered los ntawm daim phiaj, Lwm grounding yuav tau bypassed, Tiam sis internal grounding yuav tsum tau ua siv ib cable nrog ib tug tub ntxhais grounding. Yog powered los ntawm ib lub roj teeb pob nrog ungrounded ncej, tsis tsim nyog. txuas ntxiv, Hluav taws xob li nrog ob npaug los yog reinforced insulation yuav tsum tsis tau grounded.
