Corona-free lightning rod

Abstract

The invention discloses a corona-free lightning rod, comprising an upright column, lightning attraction electrodes arranged on the top end of the upright column, a horizontal grading ring arranged on the upright column and supported by a horizontal support rod and an inclined support rod, and a discharge cavity and a fixed chassis which are arranged under the upright column, wherein the lightning attraction electrodes are connected with the discharge cavity through the upright column, the lightning attraction electrodes include a main lightning attraction electrode (1) and auxiliary lightning attraction electrodes (2), the auxiliary lightning attraction electrodes are arranged on the periphery of the main lightning attraction electrode, the support rods are semiconductor support rods, the main lightning attraction electrode and the auxiliary lightning attraction electrodes are fixedly arranged on a spherical uniform field ball (3), and the uniform field ball is fixedly arranged on the top end of the upright column; and the grading ring is fixedly arranged on the periphery of the lightning attraction electrodes and is 5 cm lower than the tip ends of the lightning attraction electrodes. The invention provides a corona-free lightning rod based on changing space electrical field distribution, and further, the lightning effect is greatly increased, the lightning protection is reliable, the manufacturing is easy, and the mounting and construction are convenient.

Description

technical field [0001] The invention relates to a lightning rod, in particular to a corona-free lightning rod which prevents corona based on changing the spatial electric field distribution. Background technique [0002] At present, a large number of lightning protection works have been carried out in power systems, industries, buildings, etc., but the problem of lightning disasters still occurs from time to time, indicating that there are still problems in the current lightning protection tools and measures. In the lightning protection of the power system, because the problem of direct lightning strike cannot be solved, remedial measures such as lightning rods and lightning protection fittings are mainly used to reduce the damage effect. The lightning protection of telecommunication towers, industries and buildings mainly adopts the method of installing lightning rods to prevent direct lightning strikes, but it often cannot effectively lead lightning, and sometimes even lea...

AI Technical Summary

Problems solved by technology

The lightning protection of telecommunication towers, industries and buildings mainly adopts the method of installing lightning rods to prevent direct lightning strikes, but it often cannot effectively lead lightning, and sometimes even leads lightning to other places, causing greater losses

The main reason for these phenomena is that the current lightning protection method based on the Franklin type (ordinary lightning protection) still has certain defects, and the reason for preventing direct lightning strikes has not been fundamentally solved.
