Classification ntawm Explosion-Proof Electrical khoom

GB3836.1-2010 “Explosive Atmospheres Part 1: Cov Khoom Siv Hauv Kev Siv Rau Cov Khoom Siv” classifies tawg-proof hluav taws xob khoom Mus rau hauv ob hom raws li lawv tej chaw siv: Hoob Kawm kuv thiab hoob kawm II hluav taws xob li.

Hoob Kawm Kuv Hluav Taws Xob

Hom no yog specifically tsim los siv nyob rau hauv tej cheeb tsam hais txog underground thee tsuas thiab qhov chaw txheej txheem ntawm thee. Nws feem ntau hais txog hluav taws xob li kev khiav hauj lwm rau tej thaj chaw uas ob methane thiab thee plua plav yog tam sim no. Tus underground thee tsuas ntau lawm ib puag ncig yog notoriously nyuaj, characterized los ntawm qhov muaj qhov khuv gases xws li methane, combustible plua plav xws li thee ntoo tshauv, thiab ntxiv adversities xws li moisture, humidity, pwm. Cov mob no tswj stringent tshiab zov rau tus tsim, manufacturing, thiab siv cov khoom hluav taws xob.

Hoob Kawm II Hluav Taws Xob Khoom Siv

Cov li cater rau explosive Roj tej chaw sab nraum thee mines thiab feem ntau xa mus rau hluav taws xob khoom functioning nyob rau hauv tej yam mob (xws li ob combustible roj thiab plua plav tej chaw).
