防爆电气设备的防爆等级和防护级别(bié)是完全不同的概念(niàn)。具有防爆能力,不一定具有防水能力,也不(bú)一定具有防尘(chén)能力(lì)。在使用过程中,不可混(hún)为一谈(tán),只有正确理解和掌握了防爆与防护等级知识,才能在各种不同的使用环境下,正(zhèng)确选择和安(ān)全使(shǐ)用防爆电气设备。在恶劣环境下,要使用防爆(bào)等级(jí)高和防护(hù)等级(jí)比较高的(de)设备。用(yòng)户在电气设备选型时,应该分别对防(fáng)爆与防护等(děng)级提出要求,选(xuǎn)择防爆等级和防护等级都能满足使用环(huán)境(jìng)要求的(de)产品。
The explosion-proof level and protection level of explosion-proof electrical equipment are completely different concepts. It is explosion-proof, not necessarily waterproof, and not necessarily dust-proof. In the process of use, it should not be confused. Only by correctly understanding and mastering the knowledge of explosion-proof and protection levels can we correctly select and safely use explosion-proof electrical equipment in various use environments. In harsh environments, use equipment with a high explosion-proof level and a relatively high protection level. When selecting electrical equipment, users should separately put forward requirements for explosion-proof and protection levels, and choose products that can meet the requirements of the environment of use in explosion-proof levels and protection levels.
