Ex db IIC T6 Gb thiab Ex ib IIC T6 Gb yog ob qhov sib txawv tawg - cov ntawv pov thawj pov thawj, sawv cev sib txawv tawg- cov qauv pov thawj thiab qib kev tiv thaiv. "Ex" stands rau tawg- pov thawj, "db" rau flameproof, "ib" rau intrinsically muaj kev nyab xeeb, "IIC" rau siv nyob rau hauv Class IIA, IIB, thiab IIC explosive gas atmospheres, "T6" rau qhov siab tshaj plaws kub ntawm 85 degree, thiab "Gb" rau siab tiv thaiv theem.
1. Kev tawg tawm - hom pov thawj (Kev Tiv Thaiv Hom)
Ex db: stands rau "flameproof" (d stands for flameproof). Cov cuab yeej lub thawv tuaj yeem tiv taus qhov tawg hauv qhov tsis muaj kev puas tsuaj thaum tseem tiv thaiv cov pa tawg sab nraud. Nws tsim nyog rau siab - cov khoom siv fais fab thiab siab - qhov chaw muaj kev pheej hmoo (xws li roj av thiab tshuaj lom neeg kev lag luam).
Ex ib: stands for "intrinsically safe" (i stands for intrinsically safe). Qhov no tiv thaiv sparks los yog thermal cuam tshuam los ntawm igniting explosives los ntawm limiting lub zog hluav taws xob (voltage / tam sim no). Haum rau qis- cov khoom siv hluav taws xob thiab qhov chaw muaj kev cuam tshuam (xws li sensors thiab PLC modules).
2. Gas Group (IIC)
Ob leeg yog tsim nyog rau siv nyob rau hauv Class IIC gas ib puag ncig (xws li, siab- gases txaus ntshai xws li hydrogen thiab acetylene), qhia tau hais tias cov cuab yeej muaj peev xwm tswj tau cov pa phem tshaj plaws.
3. Pab pawg kub (T6)
Ob leeg muaj qhov kub siab tshaj plaws ntawm qhov kub tsis tshaj 85 degree, kom ntseeg tau tias lawv yuav tsis cuam tshuam qhov chaw nyob ib puag ncig.
4. Kev Tiv Thaiv Qib (Gb)
Ex db IIC T6 Gb: Gb qhia tias cov cuab yeej yuav tsis dhau los ua qhov hluav taws xob thaum lub sijhawm ua haujlwm ib txwm muaj lossis nyob rau hauv qhov kev xav tau ua txhaum cai thiab tsim nyog siv rau thaj tsam 1 thiab 2 (siab- thaj chaw muaj kev pheej hmoo).
Ex ib IIC T6 Gb: Intrinsically muaj kev nyab xeeb cov cuab yeej feem ntau muaj kev tiv thaiv Gb, tab sis qee qhov Ex ib pab kiag li lawm yuav muaj Ga tiv thaiv (kev tiv thaiv siab dua) thiab tsim nyog siv rau hauv Zones 0, 1, thiab 2.
5. Cov xwm txheej siv tau
Ex db: Feem ntau siv rau siab - cov khoom siv fais fab xws li lub cev muaj zog thiab lub thawv xa khoom, tsim nyog siv rau hauv siab - tawg- qhov chaw muaj kev pheej hmoo.
Ex ib: Feem ntau siv rau qis- cov khoom siv hluav taws xob xws li sensors thiab transmitters, haum rau siv hauv thaj chaw uas xav tau kev nyab xeeb siab.
Ex db IIC T6 Gb: Flameproof tsim qhia txog qhov tawg - pov thawj muaj peev xwm ntawm lub qhov rooj thiab tsim nyog siv rau hauv siab - cov khoom siv hluav taws xob thiab siab - cov pa phem ib puag ncig.
Ex ib IIC T6 Gb: Intrinsically kev nyab xeeb tsim qhia txog kev txwv lub zog hluav taws xob thiab tsim nyog siv rau hauv qis - cov khoom siv hluav taws xob thiab thaj chaw rhiab heev.
Ex db IIC T6 Gb thiab Ex ib IIC T6 yog ob qho tib si tawg - pov thawj ratings. Ex db IIC T6 Gb muaj kev tiv thaiv ntau dua li Ex ib IIC T6 hais txog kev tawg-cov ntaub ntawv pov thawj thiab qib kev tiv thaiv, ua rau nws tsim nyog rau cov ntawv thov nrog tawg ntau dua - cov ntaub ntawv pov thawj.
