Aviation obstruction light lightning protection measures-obstruction light lightning rod
When the rainy season approaches, the probability of aviation obstruction lights being struck by lightning will increase, especially the obstruction lights installed on the top floor. During the installation and design of aviation obstruction lights, the lightning protection facilities and lightning protection methods of aviation obstruction lights will be considered in advance. Aviation obstruction light lightning rod is a simple measure for aviation obstruction light to protect from lightning.
The lightning rod is to erect a conductive needle on the mounting bracket of the aviation obstruction light, and the height of the needle should be higher than the overall height of the lamp. The needle should have super high conductivity or conductivity, and connect the needle with the installation bracket and the overall lightning protection facilities of the building. Therefore, when the lightning strikes the position of the obstruction light, the lightning rod at the height will distract the lightning and lead it to the ground of the building. So as to avoid the phenomenon of lightning damage to the lamps.
Obstacle light lightning rods can avoid small and medium lightning strikes. For large lightning strikes, professional lightning protection facilities are needed to avoid them. Because the lightning rod can withstand a certain range of lightning strike intensity. In areas where lightning strikes frequently occur, a professional lightning protection system needs to be set up at the top level, taking into account the lightning protection of aviation obstruction lights.
Aviation obstruction lights are installed in high-rise locations and need to withstand severe weather conditions such as high temperature, low temperature, high wind pressure, and lightning strikes under certain conditions. Therefore, the Civil Aviation Administration of China issued a new inspection specification for aviation obstruction lights AC-137-CA-2017-05 "Aviation Obstruction Light Inspection Specification", which clearly defines the requirements for the use environment of aviation obstruction lights. Only the aviation obstruction lights that have passed the full inspections of the new inspection specifications and obtained the CAAC net notice can they be allowed to be sold in the market, and then they can be accepted by the civil aviation or military aviation related departments.
