Direct lightning protection device

Abstract

The invention provides a direct lightning protection device. The device comprises a high-energy voltage-sharing and current-dispersing protective cover, a current conduction positioning shaft and a high-energy biexponential function charge loading bin; the high-energy voltage-sharing and current-dispersing protective cover is arranged at the upper part of the device, the high-energy voltage-sharing and current-dispersing protective cover is rotatably connected with the current conduction positioning shaft, and the current conduction positioning shaft is electrically connected with a semiconductor in the high-energy biexponential function charge loading bin; a positioning lightning receiving area is arranged at the central point of the highest curved surface of the high-energy voltage-sharing and current-dispersing protective cover; a high-electric-field focusing lightning receiving positioning end of a columnar semicircular electric field is installed at the center circle point of a positioning lightning receiving area, each lightning receiving point of the device occurs at the high-electric-field focusing lightning receiving positioning end in the lightning receiving process of the device and an atmospheric electric field, and a high-energy double-exponential-function charge loading bin attenuates lightning current. According to the invention, the lightning receiving phenomenon is positioned without the phenomena of surrounding lightning and side lightning, the lightning ball rolling effect can be ensured to the maximum extent, and the technical significance of functionallightning receiving of the protection angle is improved to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of lightning protection, in particular to a direct lightning protection device. Background technique [0002] On September 1, 2012, the General Armament Department of the Chinese People's Liberation Army promulgated GJB7581-2012 "Lightning Protection Requirements for Mobile Communication Systems". The standard applies to the mandatory requirements for the design, development and use of direct lightning strikes and lightning electromagnetic pulse protection for mobile communication systems. Part 4.6 of the standard stipulates that the direct strike lightning protection of the mobile communication system is Class A, and the lightning electromagnetic pulse is Class B protection. The protection of mobile communication systems located in areas with many minefields, high minefields, and strong minefields is Class A and Class B, and the protection of mobile communication systems located in areas with few minefield...
