防爆電氣設備的防爆等級和防護級別是完全不(bú)同的概念。具有防(fáng)爆能力,不一定具有防水(shuǐ)能(néng)力,也不一定具有防塵(chén)能力(lì)。在使用過程中,不可混為一談,隻有正確理解和掌(zhǎng)握了防爆與防護等級知識,才能在各種不同的使用環境下,正確選擇和安全(quán)使用防爆電氣設備。在惡劣環境下,要使用防爆(bào)等級高和防(fáng)護等級比較高的設備。用戶在電氣設備(bèi)選(xuǎn)型時,應該分別(bié)對防爆與防護等(děng)級提出要求,選擇防爆等級和防護等級都能滿足使用環境要求的產品。
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.
