Abstract
The thunder and lightning disaster is 1 kind currently the mankind return and can't resist of severity nature disaster, the thunder and lightning result in the affairs of personnel's dead and injured and equipments damage often have with business enterprise information-based construction of continuously development, nicety electronics equipments drive extensive application every trade of calculator work system in, because of nicety electronics equipments the anti- conduct electricity to press, conduct electricity to flow and ism pulse of the ability be very low and have no to guard against of system once suffer thunder, the equipments will suffer serious with our country information-based construction progress of speed, information system of devotion enlargement, the information system of the work just impersonation e more importance of role, thunder and lightning disaster as to it's result in of threat and endanger also e more big, every year is several because of thunder result in calculator munication facilities damage, cause thus the information deliver break off, the information be damaged to b
e go to threat Human body safety of trouble occurrence.
[Keyword] the low pressure go together with an electricity circuit thunder to defend thunder measure
