      詳細信息

      三相防爆箱  BXMD-4K

      一、應用 

      騰陽三相防爆箱產品性能優越,密封性好、外觀美觀、安裝接線方便,具有防塵、防腐蝕、防爆、阻燃等功能。用于交流三相380V低壓配電系統中,能防止雷擊、工業噪聲或其它原因產生的感應過電壓、過電流現象和其它瞬間浪涌電壓對系統或設備造成永久性損壞或瞬間中斷等危害。本產品采用并聯方式安裝。   

      二、原理

      騰陽三相防爆箱屬于三相并聯型SPD,采用并聯瞬態浪涌釋放方式,當供電線路遭受過電壓、過電流時將雷電能量或其它干擾過電壓、過電流有效抑制,使各線路間的電位差基本保持不變,雷擊后自動恢復并指示雷擊次數,確保電氣設備安全運行。

       三、主要技術條件

      1、通流量:   60KA(8/20µs沖擊波形)  

      2、額定電壓:380V

      3、殘壓:    ≤1800V

      4、導通電壓:≥510V(相電壓)

      5、漏電流:  ≤10μA

      四、安裝與維修:

      1、將SPD安裝在配電設施或設備前端。

      2、采用并聯安裝,要求接線務必牢固。

      3、接地導線至少為16㎜2,引線長度不應大于1米。

      4、定期檢查模塊窗口指示狀態,綠色時正常,紅色時為損
