Abstract

The utility model discloses a lightning rod with a function of weakening magnetic field coupling. The lightning rod comprises an arrester, a through-flow cylinder and a grounding pedestal. The through-flow cylinder is fixedly connected between the arrester and the grounding pedestal. The lightning rod with the function of weakening magnetic field coupling also comprises spiral coil which winds the through-flow cylinder. Taps of the two ends of the spiral coil are in short circuit, and are also in short circuit with the grounding pedestal. When the lightning rod with the function of weakening magnetic field coupling leads thunder, the short-circuit spiral coil is enabled to generate induced electromotive force via a magnetic field generated by the through-flow cylinder. Current formed by the induced electromotive force in the spiral coil is led into the ground via the grounding pedestal so that magnetic field coupling formed by the magnetic field via space is effectively weakened, and thus equipment in a peripheral circuit system is protected.

Description

A kind of have a lightning rod that slackens magnetic Field Coupling function
Technical field
The utility model relates to a kind of lightning rod, relates in particular to a kind of lightning rod that slackens magnetic Field Coupling function that has.
Background technology
Lightning rod is for protecting building to avoid the device of thunderbolt, being conventionally arranged on the top of building.The arrester of lightning rod receives cloud layer and is with thunder and lightning lotus, and by through-flow conductor and lead-in wire, thunder and lightning lotus is introduced to the earth, prevents that the electric current of thunder and lightning lotus formation from causing danger by building.But, when lightning rod draws thunder, when a large amount of electric currents flow through lightning rod conductor, it is produced to powerful magnetic field around, Space Coupling is passed through in this magnetic field, other are possessed to the electric power of sensed conditions, the Circuits System generation induced electromotive force of electronics, affect devices in system and run well, even make its device damage.How slackening the magnetic Field Coupling producing when lightning rod draws thunder is that those skilled in the art have problem to be solved.
Utility model content
For the above-mentioned problems in the prior art, the utility model object is to provide a kind of lightning rod, can effectively slacken the magnetic Field Coupling producing in the time drawing thunder, and it is simple in structure, easy for installation, and coefficient of safety is high.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of have a lightning rod that slackens magnetic Field Coupling function, comprising: arrester, through-flow cylinder, ground connection pedestal, wherein, described through-flow cylinder is fixedly connected between described arrester and described ground connection pedestal
Described have the lightning rod that slackens magnetic Field Coupling function and also comprise helical coil, and described helical coil is wound around described through-flow cylinder, the two ends tap short circuit of described helical coil and with described ground connection pedestal short circuit.
Preferably, described helical coil is wound around and closely supports and paste with described through-flow cylinder along one end to the other end of described through-flow cylinder.
Preferably, the two ends tap of described helical coil is connected with a cable by waterproof wiring terminal respectively, described cable and described ground connection pedestal short circuit.
Compared with prior art, the beneficial effect with the lightning rod that slackens magnetic Field Coupling function of the present utility model is: because helical coil is wrapped on through-flow cylinder, and the shorted on both ends of helical coil and with ground connection pedestal short circuit. when this lightning rod draws thunder, the magnetic field that through-flow cylinder produces makes the helical coil of short circuit produce induced electromotive force, the electric current being formed by induced electromotive force in helical coil is introduced the earth by ground connection pedestal, effectively slacken the magnetic Field Coupling that magnetic field forms by space, thereby protected the equipment in peripheral circuits system; In addition, this helical coil structure is simple, only need be wrapped in through-flow cylinder and by its short circuit.
Brief description of the drawings
Fig. 1 is the decomposition texture schematic diagram of having of the embodiment of the present utility model lightning rod that slackens magnetic Field Coupling function;
Fig. 2 is the overall structure schematic diagram of having of the embodiment of the present utility model lightning rod that slackens magnetic Field Coupling function.
Embodiment
For making those skilled in the art better understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As Fig. 1, shown in Fig. 2, embodiment of the present utility model provides a kind ofly has a lightning rod that slackens magnetic Field Coupling function, comprising: arrester 1, and through-flow cylinder 2, ground connection pedestal 3, through-flow cylinder 2 is fixedly connected between arrester 1 and ground connection pedestal 3; The lightning rod that the having of embodiment of the present utility model slackens magnetic Field Coupling function also comprises helical coil 4, and helical coil 4 is wound around through-flow cylinder 2, the two ends tap short circuit of helical coil 4 and with ground connection pedestal 3 short circuits.With reference to figure 1, through-flow cylinder 2 is fixedly connected with arrester 1, ground connection pedestal 3 by the external screw thread at two ends, and the advantage of this connected mode is that installation and removal are convenient.Shown in Fig. 1 of the present embodiment and Fig. 2 is that through-flow cylinder is rod, will be appreciated that, through-flow cylinder also can adopt U-shaped cylinder, Curved cylinder etc., all belongs in optional scope of embodiments of the present utility model.
Because helical coil 4 is wrapped on through-flow cylinder 2; and the shorted on both ends of helical coil 4 and with ground connection pedestal 3 short circuits; therefore the through-flow cylinder 2 of this lightning rod is equivalent to the elementary of high frequency switch power; helical coil 4 is equivalent to the secondary of high frequency switch power; the magnetic field that through-flow cylinder 2 produces makes the helical coil 4 of short circuit produce induced electromotive force; the electric current being formed by induced electromotive force in helical coil 4 is introduced the earth by ground connection pedestal 3; effectively slacken the magnetic Field Coupling that magnetic field forms by space, thereby protected the equipment in peripheral circuits system.
Improve as one, lightning rod is installed on towering buildings top, often be subject to the impact of larger wind speed, for making helical coil 4 and through-flow cylinder 2 stable connections, and slacken greatly the magnetic Field Coupling that magnetic field forms by space, the helical coil 4 of the present embodiment is wound around along one end to the other end of through-flow cylinder 2, and helical coil 4 closely supports and pastes with through-flow cylinder 2, namely, as shown in Figures 1 and 2, the internal diameter that helical coil 4 surrounds is not more than the external diameter of through-flow cylinder 2.
As further improvement, the two ends tap of the helical coil with the lightning rod that slackens magnetic Field Coupling function of the present embodiment is connected with a cable by waterproof wiring terminal respectively, cable and ground connection pedestal short circuit.In conjunction with Fig. 2, the shorted on both ends of helical coil 4 also has multiplely with the mode of ground connection pedestal 3 short circuits, for example, the metal core at the two ends of helical coil 4 can be wound around and tighten, and be fixed on ground connection pedestal 3 by metallic screw.Although this short circuit mode is feasible, due to metal core wire is outside exposed, in ray process, easily cause electric leakage drawing.The cable 5 that a kind of binding post 51 with waterproof is as described in Figure 2 provided in a preferred embodiment of the present utility model, for short circuit helical coil 4 and ground connection pedestal 3, has effectively stoped helical coil 4 to leak electricity.
