防爆电气设备的防爆等级和防护级别是完全不同的概念。具有防爆能力,不一定具有防水能力,也不一定具有防尘能力。在使用过程中,不可混为一谈,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,正确选择和安全使用防爆电气设备。在恶劣环境下,要使用防爆等级高和防护等级比较高的设备。用户在电气设备选型时,应该分别对防爆与防护等级提出要求,选择防爆等级和防护等级都能满足使用环境要求的产品。
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.
