摘要
提出一种新型防雷方法,以抑制雷电下行先导的发展为基本原理,采用新型抑雷装置,通过向下行先导发送极性相反的地电荷来中和先导通道的电荷,以此来降低雷电流的幅值和陡度,从而降低雷击产生的过电压的幅值,同时,配合隔离电源和等电位连接等措施来对电力设备进行防护。
This paper presents a new lightning protection method with restraining the lightning downward precursor to be the fundamental principle.The paper uses a new type of lightning suppression device to neutralize the charge of the precursory channel by sending a ground charge with opposite polarity to the downward precursor,in which way to reduce the amplitude and steepness of lightning current so as to lessen the amplitude of the overvoltage caused by thunder stroke,simultaneously with isolated power supply and equipotential connection and other measures to protect the power equipment.
