Description
Technical field
The utility model relates to a kind of lightning protection earthing system.
Background technology
Thunder and lightning is to occur in the phenomenon that strongly sparks between the thundercloud interlayer that forms because of strong convective weather and thundercloud and the earth.May occur each season, the frequency especially occurring with summer is the highest.Thunder and lightning is a kind of natural phenomena with extremely strong destructive power, brings very large harmful effect to the mankind's production and life.Natural thunderbolt mainly contains direct stroke and LEMP two classes.Direct stroke acousto-optic is concurrent, and lightning flashes and thunder rumbles, and it is with powerful thunder-strike current, red-hot high temperature, fierce shock wave, the electromagnetic field of transition etc., damages building, power transmission line on discharge channel, hits and extremely wound people and animals etc.LEMP quietly occurs, and is difficult for discovering, and consequence is serious.It is the electromagnetic field inducing effect of the impulse form that space produces around during due to lightning discharge, make the metal objects on building, inner metal tube, reinforcing bar, hardware, power cable, signal cable etc. induce thunder and lightning high voltage, large electric current, and the approach such as the earth potential counterattack by power circuit, signal line, antenna feeder circuit and earth connection and space introduce that indoor damage is electric, electronic system equipment.Induction high voltage and the amplitude of overcurrent and the distance of lightning strike spot are inversely proportional to, and are directly proportional to amplitude and the steepness of thunder-strike current.Lightning strike spot is nearer, and the steepness of lightning current is larger, and induced pulse surge, overcurrent are just larger, also just more dangerous, just larger to the destructiveness of electric and electronic system equipment.Thunderbolt consequence may be both fire, mechanical damage, casualties, the damage of electric and electronic system equipment, also may jeopardize power supply, computer control and regulating system, caused power failure, loss of data, production to pause.According to incompletely statistics, nationwide in 1998, the information system that the grid of take is master causes the Cases of Lightning Strokes of direct economic loss units up to a million just to have 19, and annual total losses has surpassed hundred million yuan.So the important sensitive electronic equipment of building needs special lightning protection.
Recently during the last ten years, in railway power system, such as the increasing electronic equipment such as complex automatic system, telecontrol system, security video system, alternating current-direct current screen, be provided to the scenes such as electric substation, power distribution institute, switching station, bringing into play its irreplaceable important function.These electronic equipments and system are all operated under low-voltage and little current status, and its Electromagnetic Compatibility is low, and the ability of anti-lightning electromagnetic pulse overvoltage, overcurrent is very fragile, and the vulnerability under lightning environment is higher.In fact, the equipment such as the synthetic automatic device in rail traction substation, alternating current-direct current screen, were all once struck by lightning, and sometimes caused system, the serious damage of equipment, or during being struck by lightning, occurred the out-of-work dangerous situation of overprotection device.These situations, seriously jeopardize the safe operation of electric power system and management system thereof, traffic safety are caused to serious threat.These systems are carried out to the protection of direct lightning strike and LEMP, there is importance and urgency very.
