防爆電氣設(shè)備的防爆等級(jí)和防護(hù)級(jí)別是完全不同的概念。具有防爆能力,不一定具有防水能力,也不一定具有防塵能力。在使用過(guò)程中,不可混為一談,只有正確理解和掌握了防爆與防護(hù)等級(jí)知識(shí),才能在各種不同的使用環(huán)境下,正確選擇和安全使用防爆電氣設(shè)備。在惡劣環(huán)境下,要使用防爆等級(jí)高和防護(hù)等級(jí)比較高的設(shè)備。用戶在電氣設(shè)備選型時(shí),應(yīng)該分別對(duì)防爆與防護(hù)等級(jí)提出要求,選擇防爆等級(jí)和防護(hù)等級(jí)都能滿足使用環(huán)境要求的產(chǎn)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.
