The auxiliary thunder and lightning utmost point that draws can greatly increase and draws thunder effect, and semiconductor support bar, except supporting role, can also more effectively improve the distribution character of electric field, also possesses the function that discharges a certain amount of charge inducing simultaneously.
On the basis of the above, the utility model can also be improved further as described below:
Described master draws the thunder utmost point 1 and the auxiliary thunder utmost point 2 that draws is tip sharp shaped material upward, is fixed on a spherical equal ball 3, and all a ball is fixed on column top; Described grading ring is fixed on and draws around the thunder and lightning utmost point and lower than thunder eletrode tip 5cm.Voltage equalizing ball coordinates with grading ring, and the space electric field that can effectively improve lightning lead-in needle point place distributes; Adopt after semiconductor support bar, more effectively change the distribution character of space electric field.
Described column lower end for most advanced and sophisticated and as upper end electrode, pass and be fixed on 11 of the insulating ceramicses of handstand tubular at the bottom of, the nozzle of insulating ceramics is down fixed on conductive chassis, conductive chassis in insulating ceramics is provided with tip lower end electrode 14 upward, leaves discharging gap 13 between upper and lower end electrode; On the conductive chassis of lower end electrode below, have pressure releasing hole 15, play and well let out and can act on, can prevent from occurring galvanic corrosion expansion and vibration and the blast of generation in discharge process; Described discharge cavity is comprised of the tube wall of upper/lower electrode, discharging gap 13, pressure releasing hole 15 and insulating ceramics 11, draws the thunder and lightning utmost point and is connected with the column of discharge cavity by conduction, and conductive chassis has 4 bolts hole and uses for fixing.
Described insulating ceramics is provided with full skirt 10 around, can increase creepage distance.
Described lower end electrode is connected with described conductive chassis by connector.
Beneficial effect: the utility model, can not produce corona discharge phenomenon, and present the electric performance of a large sized object near local and form in the process of thundercloud electrostatic field at thundercloud.When thunder discharge starts to form guide earthward and occurs, the utility model is by the discharging gap discharging in advance in discharge cavity, thereby change space electric field, distribute, thunder and lightning has been formed to the physical electrical performance at a ground connection tip, thereby realized the thunder technology of effectively drawing.In appropriate position, install, can form initiatively ascending charge, large-area increase protection range, is not destroyed by thunderbolt generally in the scope of 500 meters of circumferences.The utility model can extensively be generalized to electric power system, building lightning protection engineering, electric railway, oil depot, airport etc. and subject to the region that thunder and lightning destroyed and deposited potential safety hazard, become a kind of effective means of disaster reduction and prevention, be also applicable to the thunder and lightning research of Climatology aspect etc. simultaneously.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model is implemented schematic diagram in the concrete installation of system for distribution network of power.
Embodiment
It is same as the prior art that the present embodiment does not relate to part.
As shown in Figure 1, halo-free lightning rod embodiment of the present utility model, comprise column, be located at the horizontal grading ring 6 that draws the thunder and lightning utmost point, supports with horizontal support bar 4 and oblique support bar 8, the discharge cavity below column and the conduction fixed underpan 16 on column top on column, draw the thunder and lightning utmost point and connect discharge cavity through column.
The outer end of horizontal support bar 4 is fixed on horizontal grading ring, inner end is fixed on column with bolt 7, the upper end of oblique support bar 8 is fixed on horizontal grading ring upper and lower end and also with bolt 9, is connected on column, and on conductive chassis, having hole 17 can be connected with miscellaneous part with bolt.
Draw the thunder and lightning utmost point and be divided into the main thunder and lightning utmost point 1 and the auxiliary thunder and lightning utmost point 2 that draws of drawing, the auxiliary thunder and lightning utmost point that draws is located at and mainly draws the thunder and lightning utmost point around, and support bar is semiconductor support bar.
The auxiliary thunder and lightning utmost point that draws can greatly increase and draws thunder effect, because like this when discharge cavity discharges, it can change rapidly the distribution of space electric field on room and time, corona is stopped immediately, guiding discharge chamber stops electric discharge, revert to normal level, and semiconductor support bar is except supporting role, the distribution character that can also effectively improve electric field simultaneously, main cause is that it can also discharge a certain amount of charge inducing.
The utility model designs the most advanced and sophisticated reversed polarity space charge layer principle forming after corona that produces of ground object according to thundercloud electric field, because discharge cavity of the present utility model can effectively and by phased manner discharge, thereby destroyed the main and auxiliary extremely lasting corona of thunder and lightning that draws, reached and draw thunder object.
