防止和减少雷电对监控中心系统造成的危害,保护人民的生命和财产安全,在进行监控中心系统防雷设计时,应根据监控中心系统的环境因素特点采取相应的防雷措施,进行全面规划,做到安全可靠,技术先进,经济合理。 Install corresponding surge protectors to prevent and reduce the damage caused by lightning to the monitoring center system, protect people's lives and property safety. When designing the lightning protection design of the monitoring center system, it should take corresponding measures according to the environmental factors of the monitoring center system. Lightning protection measures, comprehensive planning, safety, reliability, advanced technology, economical and reasonable.

Since the energy of a lightning strike is very large, it is necessary to gradually release the energy of the lightning strike to the ground through a gradual release method. We need to install corresponding surge protectors at the junction of each partition in the computer room to discharge the energy induced by lightning in layers, reducing the surge voltage, and protecting user-end equipment.

First, we need to determine how many protected zones to make. For example: we can do one, two, and three levels of lightning protection for all three defense zones in the computer room, and one or two levels of lightning protection in LPZ1 and LPZ2 areas, two or three levels of lightning protection in LPZ2 and LPZn areas, or LPZ1 Area and LPZn area for one or three levels of lightning protection.

Then, select the corresponding surge protector for the voltage. For example, the voltage is 380V, the first level of protection can choose the switch-type surge protector, model AL-SPD-52-S25 / 4; the second level of protection can choose the voltage-limiting surge protector, model AL-SPD-52 -80/4; The third level of protection can choose the voltage-limiting surge protector, model AL-SPD-51-60 / 4; the fourth level of protection can choose the voltage-limiting surge protector, model AL-SPD-51 -40/4.
