Lightning protection device for ultra-large steel structure radar

Abstract

The invention relates to a lightning protection device for ultra-large steel structure radar, which comprises a plurality of lightning rods, a plurality of insulated supports, a plurality of lightningprotection strip plates, a downlead and a ground network, wherein the plurality of lightning rods are respectively connected to a lightning protection strip, the lightning protection strip is arranged on a main body frame of the radar steel structure in an insulated manner, the plurality of lightning rods disperses and leads received lightning into the lightning protection strip and then introduces the lightning to the ground network via the lightning protection strip, or the lightning protection strip directly receives the lightning and introduces the received lightning to the ground network, and the ground network discharges the lightning to the ground. According to the invention, the lightning is effectively dispersed and led into the ground. The lightning protection device is small inoverall height and simple and convenient to assemble and disassemble, plays a role of lightning protection for the whole radar equipment, solves the problems of difficult installation and maintenanceand huge work amount caused by the construction of an ultra-high lightning protection tower in the field for the ultra-large radar with the height being over 45m in the prior art, and thus effectively reduces requirements for the field infrastructure and area of the ultra-large radar.

Description

technical field [0001] The invention relates to the field of lightning protection devices, in particular to a lightning protection device for super-large steel structure radar. Background technique [0002] At present, the application range of large-scale radars is getting wider and wider. With the development of technology and the increase of demand, the size of radar antennas is also developing in the direction of super-large; usually, radars with antenna sizes above 20m are not suitable for mobile radars. It can only be made into fixed station radar; but with the diverse requirements of the army for combat radars, large fixed station radars are also required to have functions that can be moved and disassembled. For this requirement, the main frame of large fixed station radars Bolted steel structure form. [0003] The lightning protection of traditional large-scale fixed station radar usually requires the construction of lightning protection towers in the position, and l...

Problems solved by technology

However, there are currently no national standards, military standards or industry standards for the protection range of photoelectric lightning rods. Only some foreign countries have relevant standards, and the lightning rod is an active lightning rod, which requires regular inspection and maintenance. It is operated on a high tower. The performance is poor, and there are potential safety hazards; the main problem is: currently large or super large radars need to build ultra-high lightning protection towers in the position
