瞬间变化电流检测仪的设计和应用

Design and Application of Transient Current Measuring Equipment

设计一种基于短路电流放大器的瞬间变化电流的检测仪,并对其电路工作原理和测量精度做了分析。该检测仪适合于要求损耗较小和待测回路电阻较小时的瞬变电流检测,可作为物理及电子实验低成本的检测仪器,用于单根导线电磁感应现象等实验。

Based on short circuit current amplifier, an current meter for measuring transient current is made up. The work principle and the measuring accuracy are dissertated in a detail. It is fit for measuring transient current of the circuit with small loop internal resistance and requiring loss power consumption from instrument. As physical and electronic demo experiment instrument, it can be used for single conducting wire electromagnetic induction experiment and so on.
