Description

Technical Field

[0001] The invention belongs to the technical field of lightning protection equipment, and in particular relates to a passive pulse excitation corona field lightning driver. Background Art

[0002] Lightning is a natural discharge phenomenon caused by the formation of cumulonimbus clouds in nature. Cumulonimbus clouds are charged by the convection of cold and hot air, and when it reaches a certain level, a potential difference will be formed. When the potential difference reaches a certain level, lightning will be generated. The lightning current is usually 3-30 amperes, and the voltage of lightning is very high, which is extremely destructive to ground buildings. In the process of cumulonimbus clouds generating charges, the upper part of the cloud layer is positively charged and the lower part of the cloud layer is negatively charged. Due to the principle of electrostatic induction, a large amount of positive charges gather on the ground, forming a strong electric field between the ground and the thundercloud.

[0003] In order to prevent lightning from damaging objects stored in buildings or important outdoor open spaces, various lightning protection measures have emerged. Among them, lightning repellent is a good and effective means to prevent lightning damage. However, with the use of existing lightning repellents, it is found that the current lightning repellent has poor lightning repelling effect and cannot effectively repel lightning. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a passive pulse excitation corona field lightning drive device which can actively excite corona ions without providing additional power, has good lightning drive effect, and is safe and reliable.

[0005] The technical solution of the present invention is as follows:

[0006] A passive pulse excitation corona field lightning driver comprises a metal cover, a discharge tube and a discharge electrode. A discharge ball head is mounted on the discharge electrode, and a plurality of discharge needles are mounted on the discharge ball head. The metal cover and the discharge tube are assembled to form an excitation cavity. A pulse high-voltage discharge component is mounted in the excitation cavity. The pulse high-voltage discharge component uses the potential difference between the cloud layer and the earth as a power source to excite corona ions. The discharge electrode comprises a main electrode mounted on the top of the metal cover and a secondary electrode mounted in other areas on the outer side of the metal cover.

[0007] Furthermore, an activator is installed at the lower end of the discharge tube, and the activator is installed on the support seat through a flange, and an insulating plate is arranged between the activator and the support seat.

[0008] Furthermore, the pulse high-voltage discharge component mainly includes a first inductor coil, a second inductor coil, a rectifier circuit, a capacitor and a gas ceramic discharge tube integrated on a PCB board, the second inductor coil is electrically connected to the input end of the rectifier circuit, the capacitor is electrically connected to the output end of the rectifier circuit, and the gas ceramic discharge tube is electrically connected to the capacitor.

[0009] Furthermore, one end of the wire wound on the first inductor coil is connected to the main electrode through an electric wire, and the other end is connected to the outside of the support base through an electric wire.

[0010] Furthermore, the PCB board is installed in the discharge tube through an insulating support.

[0011] Furthermore, the main electrode is mounted on the top of the metal outer cover through an insulator, and the PCB board is fixed on the insulator.

[0012] Furthermore, a plurality of discharge holes are provided on the peripheral wall of the discharge tube.

[0013] Furthermore, a down conductor is connected to the discharge tube.

[0014] Furthermore, the detachable connecting piece includes a connecting tube with one end larger than the other end, the small diameter end of the connecting tube is threadedly connected to the metal outer cover, the secondary electrode is threadedly connected to the large diameter end of the connecting tube, and a reinforcing bolt threadedly connected to the small diameter end of the connecting tube is arranged inside the metal outer cover.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention uses a pulsed high-voltage discharge component arranged in an excitation cavity formed by assembling a metal cover and a discharge tube, and uses the potential difference between the cumulonimbus cloud and the earth as a power source to excite corona ions. The positive corona charges in the corona ions are released into the air, interacting with the thundercloud charges, weakening the speed and intensity of the downward development of the thundercloud, and at the same time forming a corona shielding layer above the lightning repellent and the protected object, thereby effectively repelling lightning.

[0017] 2. The present invention adopts a method of not providing power supply, but uses the potential difference between the thundercloud layer and the ground during thunderstorms as power supply, and adopts a method of actively exciting corona ions to effectively drive away lightning;

[0018] 3. The present invention utilizes the arrangement of the main electrode and the auxiliary electrode to guide the negative charge in the cloud layer to the pulse high voltage discharge component on the one hand, and to introduce part of the negative charge into the earth on the other hand, thereby performing lightning driving and lightning protection simultaneously;

[0019] In summary, the present invention has the advantages of being able to actively excite corona ions without providing an additional power source, having a good lightning drive effect, and being safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, a passive pulse excitation corona field lightning driver comprises a metal cover 1, a discharge tube 2, and a discharge electrode, on which a discharge ball head 4 is mounted, on which a plurality of discharge needles 5 are mounted, and the metal cover 1 and the discharge tube 2 are assembled to enclose an excitation cavity, in which a pulse high-voltage discharge component is mounted, and the pulse high-voltage discharge component uses the potential difference between the cloud layer and the earth as a power source to excite corona ions, and the discharge electrode comprises a main electrode 301 mounted on the top of the metal cover 1 and a secondary electrode 302 mounted on other areas of the outer side of the metal cover 1.

An insulating plate 8 is provided between the activator 6 and the support seat 7, wherein the insulating plate 8 has a good insulating effect on the activator 6 and the support seat 7, thereby preventing the vertical pole used to install the support seat 7 from directly serving as a conductor.

[0028] In this embodiment, one end of the wire wound on the first induction coil 9 is connected to the main electrode 301 through an electric wire, and the other end is connected to the outside of the support seat 7 through an electric wire, wherein the support seat 7 is installed on a lightning protection rod commonly used in the field by bolts, so that the main electrode 301 receives the negative charge of the lower part of the thundercloud layer, and the support seat 7 is positively charged after being connected to the ground through the lightning protection rod, so that the guiding ends of the first induction coil 9 have a potential difference and the wire on the first induction coil 9 passes current. After the first induction coil 9 is energized, a magnetic field is generated, and the second induction coil 10 is in the magnetic field and generates current according to the electromagnetic effect, so that the current generated by the second induction coil 10 is stored in the capacitor as a power source.

[0029] like Figure 1 As shown, the PCB board is installed in the discharge tube 2 through an insulating support, and the insulating support provides good insulation between the pulse high-voltage discharge component and the discharge tube 2.

[0030] like Figure 1 As shown, the main electrode 301 is installed on the top of the metal cover 1 through an insulator. The insulator can be a ceramic insulator, so as to insulate the main electrode 301 from the metal cover 1, so that the charge received by the main electrode 301 is directly led to the first induction coil 9 on the PCB board; as another implementation method of PCB board installation, the PCB board is fixed on the insulator, and the PCB board is at the upper part of the excitation cavity; the main electrode 301 can be installed on the insulator by threading.

[0031] like Figure 1 As shown, a plurality of discharge holes 13 are provided on the peripheral wall of the discharge tube 2. The arrangement of the discharge holes 13 facilitates the corona charges released by the pulse high-voltage discharge component to quickly enter the atmosphere.

[0032] In this embodiment, the discharge tube 2 is connected with a down conductor 14, and the other end of the down conductor 14 is grounded, so as to conduct the charges received by the auxiliary electrode 302 to the ground.

[0034] The passive pulse excitation corona field lightning drive provided by the present invention utilizes the characteristics of the high and low potential difference in the space where the lightning drive is located on a thunderstorm day, generates a magnetic field around a first induction coil 9 through the principle of electromagnetic induction, and the second electromagnetic induction coil 10 induces a current through the principle of electromagnetic induction and stores it in a capacitor 11. When the amount of electricity stored in the capacitor 11 is sufficient to break through the gas in the gas ceramic discharge tube 12, the gas ceramic discharge tube 12 performs corona field discharge, thereby achieving the purpose of lightning drive and providing good lightning protection for the protected object. Since the electricity in the capacitor 11 is used to excite the charge of the gas ceramic discharge tube 12, it will enter the stage of electricity replenishment again. When the electricity inside the capacitor 11 reaches the level that can break through the gas inside the gas ceramic discharge tube 12 again, the corona charge is excited and released again, thereby forming a pulsed discharge.

[0035] In the present invention, the first induction coil 9, the second induction coil 10, the capacitor 11, and the gas ceramic discharge tube 12 can all adopt existing technologies, and those skilled in the art can make reasonable choices of specific models according to actual conditions.
