      一.區域的劃分

       

      1.1爆炸性氣體環境危險區域的劃分
        不同的國家和地區,按各自的標準劃分爆炸危險區域。我國根據爆炸性氣體混合物出現的頻繁程度和持續時間,將爆炸性氣體環境分為O區、1區和2區。(與IEC國際電工委員會一致)
        0區:連續出現或長期出現爆炸性氣體混合物的環境。
        1區:在正常運行時可能出現爆炸性氣體混合物的環境。
        2區:在正常運行時不可能出現爆炸性氣體混合物的環境或即使出現也僅是短時存在的爆炸性氣體混合物的環境。
        0區一般只存在于密封的容器,貯罐等內部氣體空間,在實際設計過程中1區也很少存在,大多數情況屬于2區。
        1.2防爆電器設備分為二類:
       、耦惷旱V井下用電氣設備
       、蝾惓V井以外的場合使用的電氣設備
        1.3Ⅱ類電氣設備,按其適用于爆炸性氣體混合物***大試驗安全間隙或***小點燃電流比,分為ⅡA,ⅡB,ⅡC三類;并按其***高表面溫度分為T1-T6六組。
        1.4爆炸性氣體混合物按引燃溫度分組,見表1。
        1.5爆炸性氣體混合物,按其***大試驗安全間隙(MESG)或***小點燃電流比(MICR)分級。

          引燃溫度t(℃)
        T1450   T685   表2類別
        ***大試驗安全間隙(MESG)(mm)、***小點燃電流比
       、駻≥0.9>0.8
       、駼0.5  、駽≤0.5、<0.45
      二.產品特點

      1. 本產品為復合型,開關箱采用隔爆型結構,母線箱及出線箱采用增安型結構。采用模塊結構,各種回路可以自由選擇組合。

      2. 內裝高分斷小型斷路器,具有過載及短路保護功能。

      3. 本產品全面推出新型優化的設計方案及操作機構,結構緊湊合理、通用性強、操作靈活方便、手感好。

      4. 所有緊固件均采用抗強腐蝕的304不銹鋼緊固件。

      5. 鋼管或電纜布線均可。

      6. 可根據用戶要求特制。 

       

      三、防爆儀表箱主要參數

      防腐等級:WF1      額定電壓(V): 220/380    額定電流(A):10-100A  

      防爆標志ExdeIIBT4  ExdeIICT4     支路數:DIPA20 TA,T4 4、6、8、10、12

      防護等級:IP55*IP65

      四.訂貨須知

      用戶在訂貨時,須注明配電箱的回路數、回路電流及斷路器的極數,若帶總開關則需注明總開關電流及極數,并注明進出線口方向、數量、大小。若照明、動力及漏電等混配時,則需提供原理圖。

      六、防爆儀表箱由于產品變化種類比較多,外形安裝尺寸及拼裝形式需與客戶交底后另行提供。

      同時防爆儀表箱也稱防爆儀器箱 。由于防爆儀表箱產品變化種類多,質量要求嚴格,用戶在選購時要仔細斟酌。如騰陽防爆電器有限公司生產的防爆儀器箱,具有設計合理、結構堅固、外形美觀等特點,是各種防爆儀器箱首選的理想箱體。雙門防爆儀表控制箱    防爆正壓型儀表箱     防爆多表框儀表箱  不銹鋼304 防爆儀表電箱 不銹鋼防爆溫控儀表箱   bXK-g不銹鋼防爆儀表箱    不銹鋼防爆儀表殼體
