摘要
按GB 14023-2011和GB/T 18387-2008对电动三轮摩托车电磁辐射骚扰特性进行评估测试,结果表明,低频段9 k Hz^30 MHz电磁场辐射发射在16 k Hz附近超标,高频段30 MHz^1 GHz电场辐射发射在45 MHz附近超标严重。利用近场探头进行骚扰源定位后,提出了在不同位置加镍锌磁环、金属屏蔽壳、屏蔽线缆等整改方案,整改后的测试结果满足标准要求。
According to GB 14023-2011 and GB / T 18387-2008 electric three-wheeled motorcycle electromagnetic radiation disturbance characteristics evaluated test results show that the low frequency band 9 kHz - 30 MHz electromagnetic radiation emission in the vicinity of 16 kHz overweight, high frequency 30 MHz - 1 GHz field radiation emission in the vicinity of 45 MHz higher than the standard. Using near-field probe disturbance source positioned, presented at different locations plus nickel zinc magnetic ring, metal shielding shell, shielded cables and other reform proposals, test results after the rectification to meet the standards.
