电器触点接触电阻测量装置的研究

Study on measurement of the contact resistance of electric apparatus

介绍了一种新研制的采用脉冲电流式的电器触点接触电阻测量装置，该装置采用脉冲大电流测量触点的接触电阻，实现了对接触电阻的无损伤精确测量。测量过程由计算机控制，并自动保存测量结果。

：A new instrument to measure the contact resistance was introduced in this paper． This instrument applied impulse great currents to measure the contact resistance of electric apparatus． The great current will not affect the contact of electric apparatus．The process and the results of measurement were saved automatically．
