Protectiou Measures of the Campus Network to Prevent Thunder and Lightning and Voltage Excess

The capability of the campus network system to prevent thunder and lightning and the voltage excess of LEMP is poor.Once there is a thunder and lightning,the function of the network system will be partly or even completely destroyed,which will cause heave economic losses.Thunder and lightning attack in the campus network system is mainly through power supply circuit,various network circuits and earth potential.To avoid being attacked by thunder and lightning,we should take comprehensive protection measures.This thesis aims at introducing a concrete methods to prevent thunder and lightning and voltage excess in the campus network.
