Abstract

Provided is a novel lightning arrester, solving the problem that when a lightning arrester in the prior art receives and guides thunder, current slope is extremely large and then the earth surface potential rises, and objects to be protected can be damaged because of the secondary lightning stroke effect and the ground potential counterattack effect. The novel lightning arrester is characterized in that a reflective plate (3) is arranged on a housing (1), an exciting plate (4) is arranged under the reflective plate (3), a plurality of reflective holes (31) are arranged in the reflective plate (3), a plurality of exciting rods (41) are fixed on the exciting plate (4), the plurality of exciting rods (41) are arranged under the reflective holes (31), and a central collection rod (2) and the reflective plate (3) are grounded. The novel lightning arrester is provided with the exciting rods and a flow discharge column to guide thunder in advance, so that the flow discharge time of the thunder current is moved up, the flow is increased, and the amplitude and the rising slope of the current are reduced, thereby reducing the secondary lightning stroke effect and the ground potential counterattack effect.

Description

Novel lightning arrester
Technical field
The utility model relates to a kind of lightning arrester, is specifically related to a kind of Novel lightning arrester.
Background technology
Existing lightning rod consists of with the earthing device being connected with arrester arrester mostly, there is the effect that guides and thundercloud discharge passage is provided, therefore the electric current that conventionally has tens of kilo-amperes and kilo-amperes up to a hundred flows into the earth through lightning rod, and lightning current steepness is very big, can cause the rising of surface potential, the secondary that produces thunderbolt effect and earth potential counterattack effect, can cause the damage of protected object; Meanwhile, after powerful thunder and lightning inflow surface, can in surrounding space, form induction field, weakness equipment and combustible and explosive articles are brought to potential safety hazard.
Utility model content
In order to overcome the deficiency of background technology; the utility model provides a kind of Novel lightning arrester; mainly solve existing lightning arrester and drawn thunderstorm hour connecing; electric current steepness is very big; can cause the rising of surface potential; the secondary that produces thunderbolt effect and earth potential counterattack effect, can cause the problem of the damage of protected object.
The technical scheme that the utility model adopts is: a kind of Novel lightning arrester, comprise housing, in described housing, pass and have central authorities to collect bar, described housing is provided with reflecting plate, described reflecting plate below is provided with activation plate, and described reflecting plate is provided with some reflection holes, is fixed with some rods that excite in described activation plate, the described rod that excites is positioned under reflection hole, and bar and reflecting plate ground connection are collected by described central authorities.
Described housing is wrapped with electro-insulating rubber.
Described housing lower end is connected with support bar, is welded with earial drainage post on described support bar, and described earial drainage post is cylindrical.
Described excites rod tapered with the nearer end of reflection hole.
Described activation plate and excite between rod and be provided with base, described base consists of synthetic resin.
Described support bar end is provided with adpting flange.
The beneficial effects of the utility model are: be provided with and excite rod, earial drainage post, can draw in advance thunder, make the earial drainage time advance of lightning current, through-current capacity increases, and reduces amplitude and the rising steepness of electric current, have reduced secondary thunderbolt effect and earth potential counterattack effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-housing in figure, 11-electro-insulating rubber, bar is collected by 2-central authorities, 3-reflecting plate, 31-reflection hole, 4-activation plate, 41-excites rod, 5-support bar, 6-earial drainage post, 7-base, 8-adpting flange.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
If Fig. 1 is in conjunction with as shown in figure, a kind of Novel lightning arrester, comprise housing 1, in described housing 1, through there being central authorities to collect bar 2, described housing 1 is provided with reflecting plate 3, and described reflecting plate 3 belows are provided with activation plate 4, described reflecting plate 3 is provided with some reflection holes 31, in described activation plate 4, be fixed with some rods 41 that excite, the described rod 41 that excites is positioned under reflection hole 31, and bar 2 and reflecting plate 3 ground connection are collected by described central authorities.
Described housing 1 is wrapped with electro-insulating rubber 11.Prevent that reflecting plate 3, activation plate 4 are communicated with, and cause current potential to equate.
Described housing 1 lower end is connected with support bar 5, on described support bar 5, is welded with earial drainage post 6, and described earial drainage post 6 is cylindrical.Increase mechanism's earial drainage speed and through-current capacity, protection mechanism.
Described excites rod 41 tapered with the nearer end of reflection hole 31.Be more prone to produce electric spark, ionized air.
Described activation plate 4 and excite rod to be provided with base 7 between 41, described base 7 consists of synthetic resin.Base 7 good corrosion resistances, long service life.
Described support bar 5 ends are provided with adpting flange 8.By screw, support bar 5 is fixed on to top, house, installs firmly, do not get loose.
The concrete use of the utility model is as follows: before thunder and lightning forms, reflecting plate 3 collects bar 2 with central authorities and the earth has good electrical connection, in equipotential state.Generally, between activation plate 4 and reflecting plate 3, have electric field strength, before lightning occurs, electric field strength can increase rapidly, and the potential difference between activation plate 4 and reflecting plate 3 increases rapidly, and is exciting the most advanced and sophisticated electric discharge phenomena that form of rod 41.Bar 2 air ionization between causing with exciting electromagnetism between rod 41 to increase sharply is collected by central authorities, forms descending guide, makes lightning and descending guide junction, completes and draws thunder.
The beneficial effect of utility model is: be provided with and excite rod, earial drainage post, can draw in advance thunder, make the earial drainage time advance of lightning current, through-current capacity increases, and reduces amplitude and the rising steepness of electric current, has reduced secondary thunderbolt effect and earth potential counterattack effect.
