氣體防爆電機和粉塵防爆電機有什麼區別

氣體防爆電機不適用於需要粉塵防爆電機嘅環境. 係由於佢哋遵守嘅不同國家電氣防爆標準: 氣體防爆電機符合GB3836, 而粉塵防爆電機則緊隨其後GB12476.

Motors that meet both these standards and pass tests for each can be referred to as dual-marked explosion-proof motors. These motors are versatile, allowing interchangeability in environments requiring either gas or dust explosion-proof standards.
