摘要: 在对带电极电缆的空中磁场进行实场测量验证时,电缆的形态通常与理想状态有较大差别,理想状态下的磁场模型无法对其进行有效验证。针对此问题,分析了实场条件下电缆形态与理想状态的区别,对海水中带电极电缆的空中磁场模型进行改进,并对改进前后的两种模型进行仿真计算对比。通过模型计算值与实场测量值对比表明,改进后的空中磁场模型的计算值误差较小,能够更好地适用于海水中带电极电缆空中磁场的理论验证。

Abstract: The shape of electric cable quitely differs from that of straight wire in the process of measuring the magnetic field of electric cable with electrodes in seawater, so it cannot be checked by the models of straight wire. For this question, the formula is improved by analyzing the difference between straight wire and electric cable in seawater, and the original and improved formulas are compared through simulation calculation. Comparison of calculated and measured values shows that the improved formula has smaller error, and it's more applicable to the checking of the magnetic field of electric cable with electrodes in seawater.
