摘要

为了满足大功率广播发射机的电磁兼容性(EMC)要求,保证其稳定运行,对发射机各功能单元均采取了机柜屏蔽措施。通过分析机柜缝隙对屏蔽效能的影响,结合机柜缝隙泄漏对大功率广播发射机运行造成干扰的实际故障案例,提出了高频电磁环境下抑制缝隙干扰的措施。
In order to meet the electromagnetic compatibility(EMC) requirements of high-power broadcasting transmitters to ensure its stable operation,the transmitter's various functional units have taken the cabinet shielding measures.By analyzing the influence of the gap on the shielding efficiency of the cabinet,combined with the actual fault cases of the interference caused by the gap leakage on the operation of the high power broadcasting transmitter,the measures to suppress the gap interference in the high frequency electromagnetic environment are put forward.
