Problems solved by technology

[0041] The problem is that the detection of the value of the electric field does not allow the determination of the moment at which the electric field is sufficient to cause free charges capable of creating an avalanche of electrons

Embodiment Construction

[0072] In this section, embodiments of the invention are shown within the scope of their application to protection against lightning.

[0073] Figures 1a, 1b and 2a to 2c have been described above and relate to the principle of the tip effect and its application to protection against lightning.

[0074] respectively corresponding to image 3 In the two embodiments shown in FIG. 4 , the device includes a collector 1 , 2 .

[0075] The collectors 1 and 2 include a metal rod body 1 , the first end portion 1 a of the metal rod body can be pointed, and the second end portion 1 b of the metal rod body is connected to the ground through a conductor 2 .

[0076] The first end portion 1 a can also have a different profile than a pointed, tapered profile, for example a circular profile.

[0077] As stated above, in this application, the purpose is to facilitate timely initiation of the uplink tracer, and through the rupture of the dielectric medium composed of air, the uplink tracer wi...

Abstract

The invention relates to a device for protecting against the electric effect of a physical phenomenon capable of inducing the ionisation of the medium in which it occurs, such as lightning. The device includes: means (3, 4, 5) for detecting the on-coming physical phenomenon; at least one physical phenomenon collector (1, 2) for collecting the effect of the physical phenomenon; and means (7) for initiating the collection by the collector, capable of generating an ionised channel from the collector and monitored by the detection means. The detection means are electrically insulated from the collector and include a corona effect detector capable of directly detecting a corona effect occurring at the collector.; Therefore, by observing the natural ionisation phenomenon or corona effect induced by the on-coming phenomenon and by detecting same, it is possible to trigger the action of the collector at the right moment.

Description

technical field [0001] The object of the invention is a device for protection against the effects of a physical event, such as the effects of lightning, which generate an electric current in an electrical conductor. Therefore, the invention is particularly applicable to devices known as lightning rods. Background technique [0002] Lightning is actually a high-intensity electrical discharge with great destructive power. This natural phenomenon is still difficult to predict. [0003] To confront this situation, known lightning protection systems seek to direct the discharge towards the earth in a controlled manner in order to avoid damage in industrial installations and population centers. [0004] The lightning rod remains one of the fundamental elements in these lightning protection systems. [0005] Devices of the lightning rod type in practice are thus known, arranged for example on top of certain buildings, the purpose of which is to attract lightning so that it is ch...
