Design And Impliment Of Lightning Protection For Campus Network

Both lighting and overvoltage are very harmful to computer network hardware which can not only cause data losing , mis-operation of controlling equipment ,machine death , but also destroy devices severely , interrupting service ,even making network paralysis . Therefore , knowing the dangerous of Lighting Induction deeply and protection reasonably to computer electronic information systems is urgent .Firstly ,this article clarified the forms of lighting and its dangerous and analyzed the need of university computer network lighting protection and its status quo of prevention development .Chapter ii Analyzing Lighting Current Spectrum and energy distribution by establishing Buttom Current and Channel Current . Furthermore calculate the electromagnetic field around servicing for calculating coupling overvoltage on cable .Chapter iii Analying the different ways of invasive computer network systems about zhijilei and induction lei and also calculating the voltage sensors and current with its electromagnetic around . Thus give intergrated protection systems .Chapter iv analyze the specific circumstances of Chengde Medical College Campus network systems and geogropy weather circumstance . Actually the overall program of lighting prevention systems include grounding , equipotential connection , power system and signal system prevention , shielding and planning cabling etc ,which expressed he theory of both building and maintenance .This article adapted an efficient protection measures to zhijilei and induction lei according to calculating and analyzing for computer network feature .The establishing complete lighting protection systems guide engineering practice eventually .
