       詳細說明: 
      1、 用途、工作條件
      定做各種防爆磁力啟動器1.1用途BQC□系列防爆磁力起動器(以下簡稱起動器)
      用于II類、B級或C級,T4組及以下級別組別的含有爆炸性氣體混合物的危險場所中,作為控制交流50Hz、
      額定電壓至380V、額定工作電流至100A、控制功率至50KW的三相異步電動機的起動、停止、換向,并具有
      過載、短路保護。
      定做各種防爆磁力啟動器1. 2工作條件
      定做各種防爆磁力啟動器a. 海拔不超過2000米;
      定做各種防爆磁力啟動器b. 周圍環境溫度為-20℃~+40℃;
      定做各種防爆磁力啟動器c. 周圍空氣相對濕度不大于90%(+25℃時);
      定做各種防爆磁力啟動器d. 在無顯著搖動和劇烈沖擊振動的地方;
      定做各種防爆磁力啟動器e. 在無破壞金屬和絕緣的腐蝕性氣體的地方;
      2、 結構與特點
      定做各種防爆磁力啟動器2. 1型號含義
      BQC  □ - □   □ N為可逆額定電流  設計序號 防爆磁力起動器
      定做各種防爆磁力啟動器2.2結構概述
      a. 起動器是按照GB3836.1~3—2000標準要求設計制造,并經國家指定檢驗機關檢驗合格,頒發防爆合格
      證;
      b. 起動器分復合型起動器和隔爆型起動器,復合型起動器外殼由鑄鋁合金壓鑄成型,表面噴塑,強度高,
      外形美觀,主腔為隔爆型結構,接線腔為增安型結構。隔爆外殼內裝交流接觸器、熱繼電器、Ex防爆按鈕
      或萬能轉換開關等電器元件,通過殼蓋上的按鈕或操作機構控制殼體內的元件,以達到控制電動機的起動
      、停止及換向的目的。隔爆型起動器外殼由鋼板焊接而成,表面噴塑,外形美觀,分隔爆型主腔和接線腔
      。
      3、安裝及維修
      定做各種防爆磁力啟動器3.1安裝前檢查起動器銘牌的技術數據是否符合實際使用條件。
      定做各種防爆磁力啟動器3.2安裝時注意電纜由出線口金屬墊圈、密封圈依次引入接線腔內,將出線口擰
      緊,使之密封,再將壓線板壓緊,以防止電纜拔脫。如不用的引出裝置,必須有封堵將其密封。
      定做各種防爆磁力啟動器3.3起動器的內外接地必須牢固可靠。
      5.4運行前檢查所有隔爆結合面緊固螺栓是否擰緊,沒有彈簧墊圈的及時配置,防止自行松脫。
      5.5檢修時,必須先斷開前級電源,等殼內電氣元件均不帶電時方可開蓋檢修。
      5.6隔爆面應予妥善保護,不得磕碰、劃傷、并保持清潔,如有損傷可按防爆有關規定修理。
      5.7檢修安裝時,應在隔爆面上涂204-1置換型防銹油。
      5.8非*技術人員嚴禁開蓋檢修。
      6、訂貨須知訂貨時必須說明產品的完整型號、名稱、規格及訂貨數量
