摘　　要：建筑物电子信息系统电涌保护是建筑物防雷保护系统的重要构成部分,已有国内外多项标准。但是由于其本体系统构成多样性、复杂性和易变性,难有简单、统一的保护方案,其保护原则也不甚清晰。本文对建筑物电子信息系统电涌保护原则中SPD选配、风险评估等若干问题进行讨论,以期促进保护方案的提高。Surge protection of building electronic information system is a key composition in protection system against lightning. Several standards have been established home and abroad. However, due to the variety, complexity and volatility of system compositions, a simple and unified protection scheme is hard to be established and the protection principles are unclear. In this article, issues like SPD selection and matching and risk assessment in surge protection principle of building electronic information system are discussed for the propose of facilitating the improvement of protection scheme.
