高层建筑物及电子设备防雷接地的几点思考

防雷必须接地,接地却未必能防雷。文章提出有异于传统意义上的接地观念,简析公共接地网（CBN）、雷击地电位升高造成反击的防护、变压器4点共地、屏蔽电缆埋地与接地的机理与特点,指出在这些方面应注意改进的问题与措施,并阐述接地技术、措施的新理念,以使防雷接地技术能发挥出更好的作用。

Some Thoughts of Lighting Proof and Grounding of High Rise Buildings and Electronic Devices

To prevent lightening, grounding is a must, however, grounding cannot surely prevent lightening. This article, beyond the conventional grounding concept, analyses CBN, the protection of reacting caused by ground potential rise, four poing grounding of transformer, the mechanism and characteristics of the buried and grounding shielded cable, points out problems for improvement and countermeasures. This article also expounds some new ideas on grounding technology and measures so as to bring into better effects of lightening proof grounding technology.
