帶電顯示器
Voltage Detecting Indicator
Integrated capacitive voltage detecting system shall includes the coupling dielectric ,the capacitive coupling electrode and a built-in voltage indicator with testing point. The device CVD series shall includes an indicating element and the connecting lead with voltage limiting device.
The voltage indicator CVD series is used in medium voltage switchgear systems exceeding 1KV connected to capacitive coupling electrodes.
Phase comparator CVD/TC-R is designed for comparing two phases and/or detection of primary voltage via capacitive voltage dividing system.
CVD*-IL/IX系列戶內高壓帶電顯示器配合容性高壓傳感器構成高壓帶電顯示裝置，用于顯示高壓線路帶電狀態(tài)。具有閉鎖功能的顯示器CVD*-IL系列可同時閉鎖高壓電氣設備，以防止電氣誤操作，誤入帶電間隔。
CVD*-IL/IX系列戶內高壓帶電顯示器配合容性高壓傳感器，可用于1KV以上的中壓開關柜系統(tǒng)。
驗電/核相器CVD/TC-R顯示器CVD*-IL/IX上的驗電端口，可顯示高壓線路是否帶電或核對兩臺電氣設備上的相序。
