防爆燈不一定防水.
隔爆原理 (封閉的) 防爆燈的作用是隔離爆炸性氣體的點火源. 它們的外殼不是完全密封的,有很小的間隙. 這些間隙對於預防爆炸起著至關重要的作用; as the 火焰 passes through these narrow spaces, it encounters resistance and heat dissipation, reducing the heat to levels insufficient to ignite explosives. For requirements that demand both explosion-proof and 防水的 能力, ensure the casing’s protection rating is specified as IP65 or IP66.
