CN207148223U 一种大型电力设备宽频阻抗特性的测量系统 有权

一种大型电力设备宽频阻抗特性的测量系统
摘要：
本实用新型公开了一种大型电力设备宽频阻抗特性的测量系统。目前，尚未有人提出利用较长同轴电缆测量大型电力设备宽频阻抗特性的接线方式。本实用新型的测量系统包括阻抗分析仪，所述的阻抗分析仪的测量端口连接两根第一同轴电缆，所述的两根第一同轴电缆的屏蔽层双端接地或始端接地末端短接，两根第一同轴电缆的芯线末端用于连接被测设备。本实用新型采用同轴电缆屏蔽层两种连接方式中的任一种，即屏蔽层双端接地或屏蔽层首端接地末端短接，就可以消除长电缆空间位置变化对电缆电气参数的影响，电力设备宽频阻抗特性的测量结果准确。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model discloses a measurement system of large power supply equipment wide band impedance characteristic. At present, someone does not provide to utilize longer coaxial cable to measure themode of connection of large power supply equipment wide band impedance characteristic as yet. The utility model discloses a measurement system includes impedance analyzer, impedance analyzer's measuring port connect two the 1st coaxial cable, two the 1st coaxial cable's the terminal short circuit of shielding layer bi -polar ground connection or top ground connection, two the 1st coaxial cable'sheart yearn end is used for connecting equipment under test. The utility model discloses an in two kinds of connected modes of coaxial cable shielding layer arbitrary kind, the measuring result accuracy that long cable spatial position changes the influence to the cable electric parameter, power equipment wide band impedance characteristic just can be eliminated to the terminal short circuit of shielding layer bi -polar ground connection or shielding layer head end ground connection promptly.
