Improved lightning elimination device

Abstract

The invention discloses an improved lightning elimination device, which is composed of a base, an insulating ring arranged on a protruding ring of the base, and a cap-shaped electric field intensifiersupported by the insulating ring. The cap-shaped electric field intensifier is also equipped with a needle-shaped lightning arrester. A circle of outward expansion band is arranged at the lower edgeof the cap-shaped electric field intensifier, and multiple annular corona discharge electrodes are processed on the lower surface of the expansion band. A circle of outward expansion band is also arranged at the upper edge of the protruding ring of the base, and multiple annular corona discharge electrodes are processed on the upper surface of the expansion band. The upper annular corona dischargeelectrodes and the lower annular corona discharge electrodes are horizontally symmetrical in shape and have the same diameter, and the number of the lower annular corona discharge electrodes is one to two smaller than that of the upper annular corona discharge electrodes. By using the lightning elimination device, the problem that an existing lightning elimination device fails when meeting wateris solved. Moreover, the efficiency of corona discharge is greatly improved, the amplitude of corona current is greatly increased, and the lightning elimination effect of the device is improved.

Description

technical field [0001] The invention relates to a lightning elimination device, in particular to a lightning elimination device for pilot-type elimination of thundercloud electric field. Background technique [0002] At present, in the field of lightning elimination technology, a kind of pilot type thundercloud electric field elimination device has been released, (see attached figure 1 ), its main structure is composed of a base, an insulating ring installed on the convex ring of the base, a cap-shaped electric field enhancer supported by the insulating ring and a needle-shaped lightning receptor on it, at the lower edge of the cap-shaped electric field enhancer There is an annular discharge gap at the upper edge of the protruding ring of the base. But this product has two disadvantages: (1) The discharge gap between the cap-shaped electric field enhancer and the convex ring of the base has only a pair of ring-shaped corona electrodes, and its corona discharge current is sm...

Problems solved by technology

But this kind of product has two disadvantages: (1) The discharge gap between the cap-shaped electric field enhancer and the convex ring of the base has only a pair of ring-shaped corona electrodes, and the corona discharge current is small; (2) The ring-shaped There is no rain-proof device at the discharge gap, especially the anti-creepage skirt design of the insulating ring is unreasonable. When the product encounters rain, the discharge electrodes are easily short-circuited and the lightning elimination function will fail.
