建设综合性大楼内通信机房防雷电过电压系统的必要性

Necessity of building up telecomcenter protection systems against thunderbolt overvoltage in a comprehensive building

通过了解雷电过电压的产生,分析了雷电引起的静电感应、电磁感应、雷电电磁脉冲各种危害的原理,说明随着现代大规模应用的电子器件工作电压的不断降低,其受到过压特别是雷电袭击而受到损害的可能性就大大增加,雷电和浪涌电压已成为电子时代的一大公害,因此综合性大楼内通信机房必须建设防雷电过电压系统。

By finding out the development of the thunderbolt overvoltage,all the harm of static electricity induction,electromagnetic induction and thunder electromagnetic impulse is clearly analysed. So the lower working voltage of modern massivelyapplied electronic appliances is,the more likely they will be destroyed by overvoltage,especially thunderbolt.Thunderbolt and surge overvoltage has become public enemies in this era of electronics.A comprehensive building must be equipped with antithunderbolt overvoltage systems.
