摘要
针对雷电产生时雷电流通过设备电源线、接地线及信号线进行传导对设备的损坏,提出了一种具有雷电波频率同步阻抗特性的装置,串联在雷电流入侵的通道中,阻断了雷电在设备间的传播途径,大大降低了雷电流对设备造成的损坏。通过对变电站二次接地系统的试验结果表明,95%的雷电流都被雷电流频率阻抗控制器进行了隔离,实现了高压反击的抑制。
Aiming at the damage caused by thunder and lightning current passing through the equipment power line, grounding line and signal line, the artiele proposes a kind of device with synchronous impedance characteristic of lightning wave frequency, which is connected in lightning eurrent intnlsion of the channel, blocking the lightning in the transmission of equipment between the way, greatly reducing the lightning current damage to the equipment. The experimental results of the secondary grounding system show that 95% of the lightning current is isolated by the lightning current frequency impedance controller and the suppression of the high voltage counterattack is realized.
