Mining faib lub thawvyog tsim los rau ib puag ncig uas muaj hluav taws kub hnyiab tau thiab tawg (xws li methane) xws li cov mines hauv av thiab yuav tsum muaj kev tawg- pov thawj ua haujlwm; thaumzoo tib yam faib lub thawvyog siv nyob rau hauv ib puag ncig ib puag ncig yam tsis muaj kev phom sij tawg (xws li chaw ua haujlwm thiab chaw ua haujlwm hauv tsev) thiab feem ntau xav txog kev tiv thaiv hluav taws xob thiab dej thiab plua plav.
1. Explosion-proof Performance
Mining Distribution Box:
Qhov tseem ceeb yog qhov tawg- cov khoom siv hluav taws xob pov thawj. Nws lub luag haujlwm tseem ceeb yog txhawm rau tiv thaiv cov hluav taws xob sab hauv los ntawm kev cuam tshuam cov pa hluav taws xob sab nraud. Nws feem ntau siv cov flameproof los yog intrinsically zoo tsim.
Qhov Yuav Tsum Tau Ua: Yuav tsum muaj kev tawg- pov thawj ua haujlwm. Qhov no yog qhov txawv tshaj plaws.
Flameproof: Lub casing muaj zog txaus los tiv thaiv lub siab tsim los ntawm kev tawg ntawm cov khoom tawg hauv qhov sib xyaw thiab tiv thaiv cov nplaim taws los ntawm kev sib kis mus rau sab nraud.
Intrinsically Safe: txwv lub zog nyob rau hauv Circuit Court kom txawm hluav taws xob sparks generated nyob rau hauv luv luv-circuit los yog fault tej yam kev mob yog tsis txaus rau ignite ib puag ncig explosive gases.
Nameplate Marking: Feem ntau cim nrog "Ex" (kev tawg- cov cim pov thawj), thee mines feem ntau siv "Ex d I" (Kuv qhia txog kev siv thee).
Ordinary Distribution Box:
Qhov tseem ceeb yog qhov dav dav - lub hom phiaj cov khoom siv hluav taws xob. Nws lub luag haujlwm tseem ceeb yog kev nyab xeeb kev faib hluav taws xob, tiv thaiv hluav taws xob poob siab thiab khoom siv ntau dhau.
Core Requirement: Tiv thaiv hluav taws xob poob siab thiab overload; tsis muaj tawg- pov thawj ua haujlwm.
2. Cov khoom siv plhaub thiab cov qauv
Mining Distribution Box:
Khoom siv: Feem ntau siab - lub zog cam khwb cia hlau, cam khwb cia hlau, los yog welded los ntawm tuab steel phaj.
Qauv: Hnyav-lub cev lub cev; flanges ntawm cov pob qij txha yog precision-machined; tawg- pov thawj qhov khoob yog qhov me me kom ntseeg tau tias tsis muaj nplaim taws yuav dim.
Ordinary Distribution Box:
Khoom siv: Feem ntau txias- dov steel phaj lossis yas.
Qauv: Lub teeb yuag thiab aesthetically pleasing; cov pob qij txha tsuas yog yuav tsum tau ua kom tau raws li cov kev xav tau ntawm cov plua plav thiab dej.
3. Siv tau ib puag ncig
Mining Distribution Box:Coal mines, underground metal thiab non{0}}metal mines, thiab cov chaw uas muaj kev pheej hmoo ntawm cov pa roj los yog thee hmoov av tawg.
Ordinary Distribution Box:Factory rhiav, khw malls, chaw nyob, chaw ua hauj lwm vaj tse, substations, thiab lwm yam pa ib puag ncig yam tsis muaj explosion txaus ntshai.
4. Cable nkag
Mining Distribution Box:
Inlet/Outlet Method: Siv tawg -cov ntaub ntawv pov thawj cable nkag.
Sealing: nruj nreem kaw. Siv compression-hom tawg- pov thawj sealing rings los tiv thaiv ob qho tib si kev nthuav tawm ntawm cov nplaim hluav taws tawg thiab nkag mus ntawm cov pa hluav taws xob sab nraud.
Ordinary Distribution Box:
Inlet / Outlet Wiring: Txheem knockout qhov lossis cable txuas.
Sealing: Feem ntau cov plua plav thiab tsis muaj dej, tiv thaiv kab nkag.
5. Cov qauv kev nyab xeeb
Mining Distribution Box:Yuav tsum muaj ob qho kev tawg- Daim Ntawv Pov Thawj Pov Thawj (Ex) thiab Daim Ntawv Pov Thawj Kev Nyab Xeeb Kev Nyab Xeeb Mining (MA/KA).
Ordinary Distribution Box:Yuav tsum xeem dhau National Compulsory Product Certification (3C Certification) thiab ua raws li lub teb chaws cov qauv, tab sis tsis tas yuav tsum muaj kev sib tsoo- pov thawj.
