| 摘 要： | 剩磁法是一种测量雷电参数的重要方法,其成本低,可大批量安装,能直接有效地记录到实际雷电流,但因其测量误差较大,在实际应用中受到了很大的限制.本文就如何提高其测量精度对传统的磁钢剩磁法进行了改进,并对一些影响因素进行了分析和讨论.改进后的磁钢式剩磁法选用一种具有较好剩磁特性的新型材料来制作磁钢棒,使用数字高斯计来测量磁钢...

| Abstract: | Magnetic-steel remanence method is an important method of measuring parameters of lightning. It can be used in large quantities for its low coast. It also can measure the actual lightning current directly and effectively. However, because of its greater measurement error, its practical application has been greatly restricted. In this paper, the measurement accuracy of the conventional magnetic-steel remanence method is improved, and a number of factors are analyzed and discussed. The improved method, using ... |
