摘 要:谐波电流可对电话线产生噪声干扰。文中全面分析了等效干扰电流和噪声计电流的参考标准,对比试验设备、测点以及噪声加权系数分布之间的差异,然后将不同速度等级动车组和电力机车等效干扰电流测试数据进行分析,并绘制不同功率等级下的J_(p)值曲线,最后针对同一列地铁列车的加速运行数据分别计算J_(p)和I_(pso)值,数据分析表明J_(p)值大于I_(pso)值,变化趋势一致。Harmonic currents could cause noise interference to telephone lines. Reference standards of equivalent interference current and psophometric current are analyzed in this article, which include analyzing and contrasting test equipment and measure points as well as weighting coefficient the weighted coefficient. The equivalent interference current test data of EMUs with different speed classes and one electric locomotive were analyzed by J_(p) curves at different power levels. Finally, the values of J_(p) and Ipso were calculated based on the acceleration data of the same subway train. The data analysis showed that J_(p) value was larger than Ipso value and the variation trend was consistent.
