Product description

产品简介

　　用于精密测量各种高压电气设备的绝缘介质损耗因数tgδ与电容Cx,可鉴别电气绝缘设备污染、破裂、穿孔、受潮等引起的缺陷和隐患。适用于变压器、互感器、套管、电力电缆、电容器、绝缘子、高压开关、避雷器等设备的测量。

主要特点

　　◆仪器配备了大屏幕(105mm×65mm)中文菜单界面，屏显分为左右两部分，左边为功能菜单区，右边为相关状态信息提示，每一步都非常清楚，操作简便;

　　◆仪器内部配备有日历芯片和大容量存储器，能将检测结果按时间顺序保存，随时可以查看历史记录，并可以打印输出;

　　◆仪器能够分别使用正接法、反接法、CVT自激法等多种方式测试;

　　◆仪器可在不拆除CVT高压引线的情况下正确测量CVT的介质损耗值和电容值;

　　◆仪器内部的逆变器和采样电路全部由数字化控制，输出电压连续可调;

　　◆仪器具备输入电压波动、输出短路、过压、过流、温度、接地检测等多重保护措施和功能，保证了仪器安全、可靠。
