摘要
针对防雷设计中电子设备的防雷接地,从外部防雷装置中接地体的选用、有效降低接地电阻的大小来符合国家标准要求以及选择合适的联合接地方式等3个方面阐述了合理接地的问题。通过对布线、屏蔽和接地方式,空间电磁场对通信线路的电磁感应影响情况和降阻剂对接地电阻的影响试验,总结出了能够保护电子设备的安全布线和接地方式。
For the lightning-protection and grounding of electronic devices in lightning-protection design,this article,in terms of selecting earth conductor,decreasing earth resistance and choosing proper means of grounding to protect the electronic equipment,describes how to realize the grounding properly.By simulating different wiring,shielding and grounding modes,and by the experiments on the effect of space electromagnetic field on electromagnetic induction of communication lines as well as the effect of resistance reducer on earth resistance,the safe means of lightning-protection and grounding for protecting the electronic devices are concluded.
