Shenhai Explosion-Proof
Enhanced-kev ruaj ntseg hluav taws xob yuav tsum tau encased nyob rau hauv ib tug tsim enclosure. Qhov no casing no tseem ceeb heev tsis zoo xwb rau assembling hluav taws xob components tab sis kuj rau shielding lawv los ntawm lwm ntshai heev txawm xws li solid particles, moisture, dej thiab dej. Cov hais teeb meem loj li lawv yuav ua rau luv circuits, breakdowns, thiab uas hazardous hluav taws xob discharges.
Nws yog paub tias hluav taws xob li yog lam tau lam ua rau tej yam zoo. Solid contaminants, piv txwv, muaj peev xwm ua tau kom muaj circuits, Thaum moisture yuav degrade insulation, ua kom muaj teeb meem thiab sparks – ib yam teeb meem yus xwb. Siv enclosures nrog ib qho kev tiv thaiv tsim nyog yuav tiv thaiv tau cov teeb meem no.
Raws li tus GB4208-2008 txheem, uas specifies enclosure tiv thaiv theem (IP codes), Cov theem no muaj uas muaj tuaj los ntawm IP code raws li ob tug zauv thiab tej zaum kuj ntxiv ntawv. Thawj tus xov tooj qhia txog qib uas tiv thaiv tsis tau khoom, thiab tus thib ob tiv thaiv dej. Piv txwv, Ib qho enclosure nyob IP54 muaj ib yam kawm ntawv tiv thaiv cov khoom thiab kua. GB4208-2008 categorizes tiv thaiv tsis tau solids rau hauv 6 theem thiab tiv thaiv dej rau hauv 8 theem.
Thaum nws tawm los enclosures:
Nrog cov neeg nyob qhov chaw, Yam tsawg kawg nkaus ntawm IP54 yuav tsum tau txhaj.
Nrog insulated nyob qhov chaw hauv, Nws yuav tsum muaj tsawg kawg yog IP54.

rau venting:
Nyob rau hauv Hoob Kawm Kuv cov khoom, Yam tsawg kawg yog IP54 (Rau cov-teeb-emitting nyob qhov chaw) LOS YOG IP44 (insulated nyob qhov chaw) yuav tsum muaj.
Rau Hoob Kawm II khoom, Qhov kev ntsuam xyuas yuav tsum tsis txhob tsawg tshaj IP44, Tsis hais seb hom components thoob ntiaj teb.
Yog enhanced-kev ruaj ntseg hluav taws xob li muaj intrinsically muaj kev ruaj ntseg circuits los yog lub nruab nrog cev, Cov no yuav tsum tau nyias txheej txheem ntawm cov-intrinsically zoo circuits. Cov-intrinsically zoo circuits yuav tsum tau tsev nyob rau hauv ib compartment uas tsawg kawg yog ib IP30 ntsuam xyuas, cim nrog lus ceeb toom: “Tsis txhob qhib thaum powered!”
Lub enclosure ntawm enhanced-kev ruaj ntseg hluav taws xob khoom yog tseem ceeb heev rau kev tiv thaiv thoob ntiaj teb components los ntawm lwm cuam tshuam thiab xyuas cov insulation kev kawm ntawm lub circuitry tshua intact, li no lub sij hawm “enhanced-kev nyab xeeb enclosure.”
