摘要
介绍了用于电流注入法实验的三同轴和三平行实验装置及实验方法。研究了皮电流波形对芯电压的影响、电缆始末端电阻变化对芯电压的影响以及芯电压随电缆长度的变化关系。提出了电缆末端电阻变化对芯电压幅度影响的等效电压源模型,该模型可以对外场试验的结果给予合理的解释。
The three-coaxial and three-parallel experiment equipments and method are introduced for the experiment of current injecting.The influence of skin current waveform on core voltage is studied.The effects of the starting and ending resistance change on core voltage and the change relation of core voltage with cable length are also researched.The model of equivalent voltage source for the influence of cable ending resistance change on amplitude of core voltage is put forward,a reasonble explanation is given for the results of outside field testing using the model.
