摘要（英）：

The utility model discloses a portable lightning current production device for earthing device impact resistance testing, including generator and the proof box of thunder current generator major loop, rectification silicon stack D, charging resistor R1 and dc voltage divider establish ties at step up transformer T2's output, energy-storage capacitor C and dc voltage divider are parallelly connected, energy-storage capacitor C's positive pole is connected to discharge switch S one end, and adjustable impulse modulation resistance R2's one end is connected to the other end, and adjustable impulse modulation inductance L one end is connected to adjustable impulse modulation resistance R2's the other end, and the other end of adjustable impulse modulation inductance L is through the earthing test current injection point connection ground net that awaits measuring, what await measuring the ground net has arranged all around that the earthing test backward flow utmost point and reference voltage are extremely, the earthing test backward flow utmost point is connected to the energy-storage capacitor C's of thunder current generator major loop negative pole. The device can real simulaed inductance effect and soil spark discharge effect, and ground resistance is strikeed to real test the out.
