日期:2017-02-16 瀏覽次數: ...
儀器外觀
    
主要特點
1.300米超遠距離無線傳輸,無需現場遠距離拉線。
2. 采用win7系統的平板電腦進行操作、陽光下可清晰顯示、儀器自帶高速熱敏打印機。
3. 配套上層設備管理軟件,具備設備及歷史數據管理、查詢、比較、列表、報告打印、報表生成等功能。2個USB接口支持與平板電腦的數據交換。
4. 內帶高能鋰離子電池,特別適合無電源場合。
5. 真正意義上的三相同時測量。三相電流輸入通道,有2mA和10mA兩個檔位進行選擇。
6. 模塊供電,保留接口,支持高精度鉗形微電流傳感器接口。
7. 特征數據、波形同屏顯示。
8. 多種電壓基準信號取樣方式:
有線方式:從PT端計量繞組取信號,數字信號有線傳輸。
無線方式:從PT端計量繞組取信號,數字信號無線傳輸,省去電纜長距離連接。
無電壓方式:不需要從PT端子取信號,采用軟件計算的方式找到電壓基準。
9. 安全可靠,電壓通道采用隔離變換,避免PT二次側短路,減小信號失真。
10. 帶電、停電、試驗室均可適用。
11. 體積小,重量輕,便于攜帶。
技術指標
1. 電源:電壓采集單元和儀器主機使用內部鋰電池供電。
2. 參考電壓輸入范圍(電壓基準信號):50Hz 、30V~100V。
3. 測量參數:
泄漏電流全電流波形、基波有效值、峰值。
泄漏電流阻性分量基波有效值及3、5、7次有效值。
泄漏電流阻性分量峰值:正峰值Ir+、負峰值Ir-。
容性電流基波,全電壓、全電流之間的相角差。
運行(或試驗)電壓有效值。
避雷器功耗。
4. 測量準確度:
電流:全電流>100μA時:±5%讀數±1個字;
電壓:基準電壓信號>30V時:±2%讀數±1個字。
5. 測量范圍:泄漏電流:100μA~10mA(峰值);
電    壓:30~100V(有效值)。
6. 外形尺寸:280×200×160 (mm)
7. 主機重量:4.5kg
電壓取樣方式為:電壓互感器(或試驗變壓器儀表繞組)的電壓信號經過帶保險絲的電壓測試線接入電壓通道,作為參考電壓信號。
電流取樣方式:電流通道為內置穿芯式小電流傳感器取樣方式,信號失真小。
