Embodiment Construction

[0034] figure 1 Shown is a storm detection device 1 comprising a cylindrical housing 2, eg made of stainless metal. The longitudinal axis of the housing 2 is almost parallel to the direction Z (ie the vertical direction). The upper part of the housing 2 is closed by a panel 3, eg made of stainless metal, and the lower part of the housing is closed by a bottom shell 4, eg made of stainless metal.

[0035] The device 1 comprises a measuring device for the electrostatic field of the atmosphere, comprising a set of electrodes E. The set of electrodes E for example includes E 1 ,E 2 ,E 3 ,E 4 ,E 5 ,E 6 ,E 7 ,E 8 ,E 9 ,E 10 ,E 11 ,E 12 , these electrodes are along a circle 6 of radius r (at figure 2 Indicated by dashed lines) are regularly arranged on the upper surface of the panel 3. Electrode E 1 to E 12 sufficiently separated from each other to avoid short circuiting of the electrodes by water droplets, hail grains, or any other conductive object that could be l...

Abstract

Storm detection device (1) comprises at least one pair of electrodes for measuring the atmospheric electrostatic field, a rotating screen (5), capable of simultaneously subjecting each electrode of said at least one pair of electrodes to the atmospheric electrostatic field and then of simultaneously isolating each electrode of said at least one pair of electrodes from the atmospheric electrostatic field, and a central processing unit capable of processing signals coming from said electrodes in order to determine a possible risk of a storm, characterized in that said rotating screen comprises a disc having slots capable of exposing said electrodes during a portion of a revolution of said rotating screen in order to subject them to the atmospheric electrostatic field.

Description

technical field [0001] The object of the present invention is to provide a storm detection device. Background technique [0002] In many situations, lightning can be dangerous to people or equipment, and awareness of the potential for a storm can take appropriate precautions. Said hazards can occur, for example, when people work on equipment that is not protected against lightning, when explosives are used for civil or military purposes, during operations with liquid fuels (diesel or gasoline), when electronic When the equipment is not fully protected against overvoltages caused by lightning, etc. [0003] For detecting storms, inter alia, radio wave measuring devices, weather radars and atmospheric electrostatic field measuring devices have been provided. [0004] The atmospheric electrostatic field, which is vertically oriented and can be positive or negative, is of the order of 100 to 150 V / m in good weather. In the vicinity of charged storm clouds, the atmospheric ele...
