Kev Taw Qhia Kev Xaiv rau Tib Neeg Lub Cev Electrostatic Discharge Devices (Key Focus: Explosion{0}}proof & Safety)
1) Kev xaiv raws li kev faib cov cheeb tsam txaus ntshai (Ua raws cai)
Tsis yog- thaj chaw muaj kev phom sij (Kev cob qhia dav dav / Cov chav neeg rau zaub mov): Txheem stainless hlau kov pob; qauv yooj yim, tus nqi qis.
Standard stainless hlau tib neeg lub cev electrostatic paug ntaus ntawv
Cov cheeb tsam uas muaj kev phom sij (Zones 0/1/2; cov chaw tso roj / tshuaj nroj tsuag / chaw nres tsheb roj): Yuav tsum xaiv qhov kev tawg tsis zoo ntawm qhov chaw ({3}} qauv pov thawj (Ex ia IIC T4 Ga); kov lub taub hau ua los ntawm sub-conductive (semiconductor) khoom; ua-nyob rau hauv tam sim no- txwv resistor (10⁶–10⁸ Ω) kom tshem tawm sparking.
Kev tawg- pov thawj tib neeg lub cev electrostatic tso tawm khoom
Cov qauv ntse (cov ntsiab lus tseem ceeb / siab- qhov yuav tsum tau muaj): tawg- pov thawj + suab- pom / lub suab ceeb toom + kev saib xyuas hauv av + cov ntaub ntawv kaw; Lub teeb ntsuab qhia tias kev tso tawm tiav, tiv thaiv "tso tawm cuav."
Lub suab ntse- pom lub tswb ceeb toom tib neeg lub cev hluav taws xob tawm hluav taws xob
2) Core parameters (Yuav tsum tau specifications)
Tawm tsis kam: 10⁶–10⁸ Ω (National Standard GB 12158); qeeb dhau yog tsis muaj kev nyab xeeb, ceev heev txaus ntshai sparking.
Lub sijhawm tso tawm: Tsawg dua lossis sib npaug li 1 thib ob (txo qhov muaj peev xwm ntawm ± 15kV mus rau qis dua ± 100V).
Grounding kuj: Tsawg dua los yog sib npaug rau 10 Ω (qhov chaw txaus ntshai) / Tsawg dua lossis sib npaug rau 100 Ω (cov cheeb tsam dav); siv ntau dua los yog sib npaug rau 16mm² stranded tooj liab hlau rau hauv av.
Cov ntaub ntawv: Kov lub taub hau yog sub-conductive/semiconductor (rau tawg- qauv pov thawj); kem yog stainless hlau los yog anti-corrosion carbon steel.
3) Kev teeb tsa thiab ua raws (GB 50074 / GB 12158)
Qhov chaw teeb tsa: Sab nraum lub twj tso kua mis lub qhov rooj, ntawm qhov chaw cia khoom nkag, chaw thau khoom / tshem tawm qhov chaw nkag, thiab lub davhlau ya nyob twg / chaw nres tsheb.
Qhov siab: Kov pob ntawm 1.0-1.2m; qhia meej.
Txwv tsis pub nruj: Siv cov khoom siv hlau hauv cov chaw muaj kev phom sij (kev pheej hmoo ntawm sparking).
