Product Description
When a single-ball optimized lightning rod is struck by lightning, the lightning current amplitude and steepness are reduced and the discharge time is extended through the air gap discharge shunt unit and the current limiting unit, so that di/dt is reduced, thereby reducing the destructive effect of lightning induction.
Working principle of single-ball optimized lightning rod
The spherical single-ball lightning lightning arrester is a non-inductive, low-impedance metal inner conductor down conductor, which transmits the lightning current after lightning to the earth and prevents the protected antenna tower or building from being side-struck and electrified.
Product Features:
Single-needle ball lightning rod characteristics: a ball-shaped single-needle lightning air-termination device, which is a non-inductive, low-impedance metal inner conductor leading down the wire, transmits the lightning current after flashing to the earth, and makes the protected antenna tower or The building will not be flanked and charged.
Scope of application
Wireless communication base stations, flammable and explosive warehouses, high-rise buildings, universities, hospitals, civilian, military ships, historic airport buildings, racetracks, sports field chemicals, rubber, oil depots, weather stations, petroleum gas stations, military bases and mines Field and so on.
Technical Parameters
Maximum discharge current (KA) 300
Wind resistance (m/s) 40
Ball diameter (mm) φ200
Needle diameter, needle length, needle number (φmm*Mmm*P) φ16*300*1 main needle number: 1
Weight (Kg) 3.5 Total height (m) 1.5~2.0
Flange specification
1. It is necessary to cast a cement base in advance at the installation location, and embed anchor bolts or use expansion screws.
2. Install the lightning rod, fix the lightning rod base on the prefabricated cement base, and reliably connect the lightning rod tower base and the cement base with anchor bolts (or expansion screws).
3. The lightning rod should be installed on a pole, iron tower or other building. The flange of the lightning rod must be more than 1.5m higher than the highest protection object. According to this requirement, set the extension pole height or iron tower height.
4. The protection distance between the independent lightning rod and its grounding device and the entrance and exit of the road or building shall comply with the regulations. The distance shall be greater than 3m. When it is less than 3m, equalization measures shall be taken or pebbles or asphalt shall be laid.
5. The installation and detection of lightning rods shall not be carried out on thunderstorm days.
6. The grounding wire of the lightning rod must be reliably connected to the earth, and the grounding resistance value shall meet the requirements of national standards.
7. Check regularly (once a year) whether the connecting screws and welding parts of the lightning rod are firm, and whether the grounding down conductor is reliably connected to the grounding system. If the connecting screws and welding parts are found to be seriously corroded, the screws must be replaced and reconnected, and the original welding parts must be re-welded.
