1接地装置的参数接地装置包括各种多功能的设备,并且需要满足防止浪涌和电磁兼容性接地的所有安全和操作的要求。为了达到这个标准,电气接地设备(输入电阻、工作时长及触摸和跨步电压等)的操作特性必须同时符合交流(频率为50Hz)和脉冲电流的要求。接地装备的波形参数具备实用和科学的研究价值,例如:波的传播常数和速度、兴波阻力、反射和折射指数等。在研究离散接地设备的雷击电流和电压分布情况时需要参考这些参数。雷电流的能谱很宽,电流范围为2kA(约85%~90%)~200kA
1 grounding device parameters Grounding devices include a variety of multi-functional devices, and need to meet the surge and electromagnetic compatibility to prevent ground for all safety and operational requirements. To meet this standard, the operating characteristics of electrical grounding devices (input resistance, operating hours, touch and stride voltages, etc.) must comply with both ac (frequency 50 Hz) and pulsed current requirements. Grounding equipment waveform parameters with practical and scientific research value, such as: wave propagation constant and speed, wave resistance, reflection and refraction index. These parameters need to be referenced when studying the lightning strike current and voltage distribution of discrete grounded equipment. The energy spectrum of lightning current is very wide, the current range is 2kA (about 85% ~ 90%) ~ 200kA
