摘要
探讨了开尔文滴水起电机要求环境凉爽、干燥的原因,并对传统的开尔文滴水起电机进行了改进,通过改善传统滴水起电机的表面绝缘性,增大水溶液的离子浓度以及预加初始电荷等方法使其能在潮湿的环境下快速获得较大的高压静电,起电效果明显.
Why Kelvin dripping-water charge collector requires cool and dry external environment was discussed and the traditional Kelvin dripping-water charge collector was improved by improving the collector's surface insulation,increasing the ion concentration in the solution and introducing initial electrical charge in advance.The improved collector could gain relatively remarkable high electrostatic voltage within a short period of time even in humid atmosphere.
