【摘要】：为向输电线路雷击大电流测量装置提供稳定可靠的电源,基于电磁感应原理设计了一种自供能雷电流监测装置,在雷电流入地通道(杆塔、避雷针、接地引下线)上安装信号线圈和取能线圈,当取能单元被雷电流触发后,即开始获取雷电流电磁能量,同时,信号线圈将对雷电流极性和峰值进行采样和存储。通过理论推导并借助Saber软件,最终确定取能和信号线圈的结构,并合理选取其尺寸等参数。研究结果表明,前置取能线圈能够通过连接相应的电能适配电路,向负载电路进行稳定供能。雷电流传感器能够对幅值介于10~200 kA之间的雷电流进行线性测量。
[Abstract]:In order to provide a stable and reliable power supply to the high current measuring device of lightning strike of transmission line, based on the principle of electromagnetic induction, a kind of self-supplying lightning current monitoring device is designed. When the energy collection unit is triggered by the lightning current, it begins to acquire the electromagnetic energy of the lightning current, and at the same time, The signal coil will sample and store the polarity and peak value of lightning current. Through theoretical derivation and with the help of Saber software, the structure of the signal coil and the structure of the signal coil will be determined, and the parameters such as the size of the coil will be reasonably selected. The results show that, The front-end coil can supply energy stably to the load circuit by connecting the corresponding electric power adaptor circuit. The lightning current sensor can measure the lightning current between 10kA and 200kA linearly.
