摘　　要：为了分析罗氏线圈非理想工作情况对测量结果的影响,在假设线圈绕制完全均匀的前提条件下采用了积分算法对非理想工作情况进行分析计算,包括:被测电流导体偏离线圈中心位置、线圈周围存在干扰磁场。计算结果表明:在绕线完全均匀的条件下,上述两种非理想情况对线圈测量结果没有影响。最后分析了被测电流导体与线圈平面不垂直的非理想工作情况的影响。In order to analyze the impact of the non-ideal work situation of the Rogowski coil on the measurement result, the integration algorithm is used for analytical calculation of the non-ideal work situation under the assumption that the coil is winded uniformly, including the measured current-carrying conductor deviating from the center of the coil, and an disturbing magnetic field existing around the coil. Calculation results indicate that the above two kinds of non-ideal situation do not affect the coil measurement results when the coil is winded uniformly. FinallyI this paper analyzes the impact of the non-ideal situation where the measured current-carrying conductor and the coil plane are not vertical to each other.
