Example Embodiment
[0030] Combine below figure 2 , Explain the specific implementation of the shunt of the present invention:
[0031] Taking the measurement of 1kA pulse current source standard as an example, the available shunt structure parameters are: 8 pairs of cage poles inside and outside, cage pole radius 1mm, outer cage pole length 105mm, inner cage pole length 80mm, the conductor material is constantan , Its nominal resistance is about 1.5mΩ.
[0032] In use, the current input and output can be connected to the first conductive disk 4 and the second conductive disk 5 of the shunt through the radio frequency coaxial connector, and the voltage measurement can be measured by measuring the potential difference between the center wire 8 and the third conductive disk 7 Obtained, the voltage is about 1.5V.
