摘要
为了能对雷云背景下的感应电荷进行研究,搭建了模拟雷云的试验平台和研制了感应电荷测试仪。模拟雷云的试验平台由一个直径3m的金属圆盘构成。通过对该金属圆盘施加变化的电压,模拟电场的快慢变化。在金属圆盘上施加的直流电压,通过瞬间断电方式模拟电场的缓慢变化;在金属圆盘上施加冲击电压模拟电场的快速变化。感应电荷测试仪测量这两种方式下的感应电荷。试验结果表明,研制的感应电荷测试仪能够实现对模拟电场缓慢变化和快速变化的测量,该设备可以应用于感应电荷测试研究。
To study induced charge with simulated thundercloud background, a thundercloud simulation test platform has been built, and the induced charge tester developed. The test platform consists of a metal disk with a 3m diameter. Change of electric field can be simulated by applying changing voltages to the metal disk. Slow changes of the electric field can be simulated by applying instantaneous power-off of the DC voltage to the disk, while fast changes can be simulated by applying impulse voltages to the disk. The induced charge can be measured with the tester using these two methods. The results show that the induced charge tester can measure simulated fast and slow fields. Therefore the developed tester can be use in the study of induced charge.
