      XD-J防爆檢修動力配電箱(自耦減壓起動)(IIB IIC)

         

      適用范圍
      1、爆炸性氣體環境:1區、2區
      2、場所中危險氣體或蒸氣:IIA、IIB、IIC
      3、溫度組別:T1~T6
      4、戶內、戶外(防護等級IP54, 可達IP65)




      產品特點
      1、該產品適用于14-135KW三相異步電動機不頻繁自耦降壓起動和停止用
      2、鑄鋁合金或鋼板焊接外殼,表面噴塑
      3、殼體內裝有自耦變壓器、真空交流接觸器、時間繼電器、熱繼電器、中間繼電器、電流互感器、轉換開關、熔斷器、電 壓表、電流表、指示燈等元件
      4、起動電流不超過電機額定電流的3-4倍,起動時間為5-120秒,并可調整。若連續起動時間總和己達120分鐘,需有足 夠的冷卻時間,一般不小于4小時,才能再次起動,不適宜頻繁操作
      5、具有過載、短路保護功能
      6、進線腔、元件腔、出線腔分別獨立
      7、輸入、輸出三相五線制(3P+N+PE)
      8、可根據用戶要求特制
      9、可鋼管或電纜布線,電纜布線須配電纜夾緊密封接頭

        Applying scope
      1、Explosive gas atmospheres:Zone 1&2
      2、Dangerous gases or vapors zone: IIA、IIB、IIC
      3、Temperature classes:T1~T6
      4、 Indoor and outdoor (IP 54,It could be designed as IP65 according to user′s requirements)

      Features
      1、Suitable for 14-135KW three-phase asynchronous motor,which is not frequently auto transformer started and stopped
      2、Enclosure is made of casting aluminum alloy or steel plate,surface is sprayed with plastics
