                                                               DXN indoor high-volt charged display device

一﹑適用范圍和特征 

     戶內(nèi)高壓帶電顯示裝置由三個傳感器和一個顯示器經(jīng)導線連接組成。適用于額定頻率50Hz，額定電壓40.5KV以下的戶內(nèi)高壓電氣設備上，既可放映回路帶電狀況，還可于電磁鎖配合，實現(xiàn)強制閉鎖開關(guān)手柄﹑閥門等。帶電顯示和強制閉鎖均受同一高壓信號所控制，但電路系統(tǒng)又是相互﹑互不干擾，只要高壓回路帶電，即使顯示電路和閉鎖電路同時出故障，電磁鎖仍處于閉鎖狀態(tài)，誤操作，誤入帶電間隔。 

The first item：application range and characteristic

      The indoor high volt charged display device is composed of three sensors and display（through lead connection），it is applied to certain indoor high volt electric equipment of rated frequency 50Hz and rated volt below 40.5KV，by this device，it could indicate charged condition in circuit，besides，it can be coordinate-operated with electromagnetic lock，which realizes forced lockout of switch handle and controlled by one high volt signal，while，its circuit system is stand-alone and not interfered one another。Just needing the high volt circuit electrified，even if display circuit and latching circuit arise fault simultaneously，the electromagnetic lock still stay in locking state，which could prevent from mishandle or entering into charged spacing。
