The scene includes a wide span of towering transmission towers carrying power lines against a clear, bright sky. The lines buzz with electricity, creating a central point of focus. In the foreground, a variety of scientific instruments, such as oscilloscopes, volt meters, and computers with live data displays, are set up for monitoring and experimenting with the power carried by these lines.

使用高压输电线进行科学实验

YouTube频道“Double M Innovations”上提出的最新想法之一是利用230千伏的输电线路进行科学实验。在最近的一个视频中,他们展示了使用普通围栏从这些输电线路获取电能的概念测试。

这个实验涉及一个容量为88微法的电容器,电压为1200V,一个完整的整流电路,以及一个73米长的同轴电缆,在输电线路下方运行。电缆安装在1.2米(4英尺)的高度,与地面保持相同高度以避免接触。同轴电缆的铜屏蔽层的一端连接到整流桥,另一端连接到插入地面的金属棒。然后电容器被充电。

实验的结果既令人担忧又令人印象深刻。最大交流电压为1000VAC的万用表在整流桥的交流侧偏离了刻度,电容器在实验中到1000V之前慢慢充电。

根据电容器的电容和最终实现的907VDC的电压,可以估算收集了大约36.2焦耳的能量。这给出了在放置在这种输电线路下的几公里长围栏上可以获得的功率的概念。但是,如果收集能量不是目标,建议对这些围栏接地。

关于在围栏上感应区域存储能量是否可以合法利用,需要与当地的电力公司讨论。

特别感谢Keith Olson提出这个想法。
