Abstract
The utility model discloses a large-protection angle protection device against direct lightning strike, which consists of an induction cap, an induction ring, an induction cap strut, an induction ring support rod, an induction switch and a grounding support, and the components are fixed into a whole in a penetration manner and called as a group; and the induction cap and the induction ring are connected into a whole through the induction cap strut and the induction ring support rod, and arranged above the induction switch, and the grounding support is arranged below the induction switch. The utility model provides a novel lightning arrester with large protection range and small discharge current against the problems of a Franklin lightning rod in application, thereby achieving the purposes of excellent lightning protection effect and small lightening hazard and having obvious economic benefits and social benefits.
Description
Technical field
The utility model relates to brand-new direct striking thunder prevention device; being applicable to that electric power, post and telecommunications, TV, finance, railway, chemical industry, oil, munitions etc. need the various device of strict lightning protection and the lightning protection of civil buildings, specifically is a kind of big shielding angle direct striking thunder prevention device.
Background technology
Since American Franklin invention lightning rod in 1749, the history in existing more than 200 year, this lightning rod is used till today, it is by arrester (needle point), downlead and earthing device are formed, its effect is to attract lightning by arrester, and by downlead and earthing device the thunder and lightning electricity is leaked into the earth.Theory and practice proves that all there are many defectives in the Franklin lightning rod, and 1. protection range is little, and uncertain, cause the shielding accident easily.2. it is big to connect the amplitude of lightning current that flashes into ground, and in its vicinity aerial or underground the counterattack problem arranged goes into ground moment can produce higher step voltage and touch voltage, jeopardizes personal safety and device security.3. connect the high-intensity magnetic field that the powerful lightning current when dodging produces, form induction overvoltage on metal tube that can be around protected object, the plain conductor, this moment, the safe operation to microelectronic element and equipment had sizable threat.
The utility model content
It is good that the purpose of this utility model provides lightning protection effect, and reducing damage to crops caused by thunder is the big shielding angle direct striking thunder prevention of purpose device.
The purpose of this utility model is achieved in that big shielding angle direct striking thunder prevention device, is made up of induction cap, inductance loop, induction cap pillar, inductance loop support bar, inductive switch and grounded bracket, runs through to be fixed as an integral body and to be called one group; Induction cap and inductance loop connect as one by induction cap pillar, inductance loop support bar, and it is arranged at the top of inductive switch, and grounded bracket is arranged at the below of inductive switch.
It establishes one group or establish more than one group at least by big shielding angle direct striking thunder prevention device provided by the utility model.Described induction cap is positioned at the center of inductance loop, and its bottom surface and inductance loop are on a horizontal plane.
Operation principle of the present utility model is: thunderbolt is the electrical breakdown of air, and can electric field strength be mainly measuring of puncturing of air.Metallic conductor surface field intensity is proportional to the charge density of conductive surface, and the conventional lightning conductor area is little, the charge density height, and electric field strength is big, so subject to thunderbolt.Use a kind of spherical convex device; be installed in the peak in the regional area; the guide who is thunder and lightning interacts down; the partial charge surface density is impaired in the safe range; weaken the thunder and lightning development of guiding protection zone earlier; stop thunder and lightning formation of main discharge channel over the ground, and reach the purpose that reduces damage to crops caused by thunder in this zone.
The utility model and conventional lightning conductor compare: 1. protection range is big, and shielding angle is 60 °-70 °, and the shielding angle of traditional lightning rod is worth much smaller than this.2. discharging current is little, and in seven kilo-amperes, and the amplitude of lightning current that conventional lightning conductor connects when dodging is that tens kilo-amperes are to hundreds of kilo-amperes.Therefore application of the present utility model does not have the counterattack problem, reduces greatly even has eliminated " step voltage " and touch voltage, guarantees personal safety and device security.Can or seldom not produce induction overvoltage on the metal tube around it and the lead when 3. discharging, guarantee the safety of system's microelectronic element such as electric power, post and telecommunications, finance, TV, chemical industry, oil, munitions and equipment thus.And the Franklin lightning rod connects when dodging discharge, can produce very strong electromagnetic field around down conductor system, this electromagnetic field in its vicinity metal tube and lead on produce induction overvoltage and damage microelectronic device.
The utility model designs a kind of big shielding angle direct striking thunder prevention device, and it can overcome conventional lightning conductor (Franklin lightning rod) defective technically at secure context.Little as protection range, to connect when dodging discharging current big, and counterattack problem or the like is arranged, the utility model all will be overcome, and lead thereby reduce damage to crops caused by thunder greatly.

Among the figure: 1: induction cap 2, inductance loop 3, induction cap pillar 4, inductance loop support bar 5, inductive switch 6, grounded bracket
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further: shown in Fig. 1-4, big shielding angle direct striking thunder prevention device, form by induction cap, inductance loop, induction cap pillar, inductance loop support bar, inductive switch and grounded bracket, run through being fixed as an integral body and being called one group; Induction cap and inductance loop connect as one by induction cap pillar, inductance loop support bar, and it is arranged at the top of inductive switch, and grounded bracket is arranged at the below of inductive switch.It establishes one group or establish more than one group at least.Described induction cap is positioned at the center of inductance loop, and its bottom surface and inductance loop are on a horizontal plane.Except that inductive switch, they all are the good conductors of electricity.The utility model is installed the high point of each building, and the safety requirements that height should satisfy the protection thing is set, and accomplishes that protected object all covers in the safe range of protection, and is big as protection range, and promptly with many group devices, the down conductor sectional area should be not less than 80mm
2Round steel or greater than 100mm
2Band steel.The earth resistance requirement, the relevant regulations value of formulating by country is provided with.
