    Abstract：At present,a clear lightning protection grading standard is short in the explosion hazard area and the existing lightning protection codes only conceptually grade from the perspective of possibility and consequences of lightning troubles. The design and safety management codes in various industrial explosion hazard sites are deeply studied based on the practice,contrastive analysis and simulation calculation are combined to gain the lightning protection classification standard for explosion hazard areas in Chongqing region,which better solves the classification of lightning protection of such places.

  摘　要：目前爆炸危险场所缺少明确的防雷等级划分标准，既有的防雷规范仅从发生雷电事故的可能性和后果的角度出发，概念性地进行了划分，可操作性较低。以实践为基础，深入研究各种行业爆炸危险场所设计和安全管理规范，结合对比分析和模拟计算得出重庆地区爆炸危险场所防雷分类标准，较好地解决了该类场所雷电防护类别划分问题。
