防爆電氣設備(bèi)的防爆等級(jí)和防護級別是完全不同的概(gài)念。具有防爆能力,不一定具有防水能力,也不一定(dìng)具有(yǒu)防塵能力。在(zài)使用過程中,不可混為一談,隻有正確理解和掌握了(le)防(fáng)爆(bào)與防護等級知識,才(cái)能在(zài)各種不同的使用環境下,正確選擇和安全使用防爆電氣設備。在惡劣(liè)環境下,要使用防爆等級高和防護等級比較(jiào)高的設備。用戶在電氣設備選型時,應該分別對防爆與防護等級提出要求,選(xuǎn)擇防爆等級和防護等級都能(néng)滿足使用(yòng)環境(jìng)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.
