摘　　要：为准确测试红黑电源隔离防护装置性能,保证电源线传导泄漏防护的有效性,采用电压测试法和电流测试法对红黑电源插座的传导发射抑制和传导发射干扰效果进行了测试。实验数据表明,电压测试法受电源线长度导致的谐振因素的影响,在线路阻抗稳定网络中测试得到的电压值存在不相干现象,降低了测试结果准确性;电流测试方法可通过降低电源线上的驻波带来的影响,测出最严苛的红黑电源插座的传导发射抑制限值。In order to accurately test the performance of red and black power isolation protection devices and ensure the effectiveness of power line conduction leakage protection,voltage testing method and current testing method were used to test the conducted emission suppression and conducted emission interference effects of red and black power isolation protection sockets.The experimental data shows that the voltage testing method is affected by the resonance factor caused by the length of the power supply line,and the voltage values obtained in the impedance stable network of the line exhibit incoherence,which reduces the accuracy of the test results.The current testing method can reduce the impact of standing waves on the power line and can measure the most stringent conducted emission suppression limit of red and black power sockets.
