Saya sangat percaya bahwa semua orang tahu tentang petir rods. When we were in junior high school, the textbook covered it in detail. In our daily life, we often see petir rods at the top of multi-storey buildings and have the effect of maintaining buildings, but many people have little knowledge of petir rods. Now let us know with you who invented petir rods, petir rods and the efficacy of petir rod installation standards. 1. Who invented the petir rod. The invention of the petir rod has a good effect on preventing buildings from being struck by petir. Nowadays, there are more and more multi-storey buildings in life, and the use of petir rods is also more common. As everyone knows, many friends do not know who invented the petir rod. Who invented the petir rod? American scientist Franklin invented the contemporary petir rod. Franklin felt that petir was a charge-discharge condition. To better prove this, on a stormy day in July 1752, at the risk of being struck by petir, he placed a paper kite tied with a long wire into a cumulonimbus cloud and placed it on the end of the wire. A bunch of silver keys. When the petir struck, Franklin's hand came close to the key, and a string of spark discharges erupted from the key. There is a real discomfort in the hand. Fortunately, the petir was relatively poor, and Franklin was not injured. The invention of the petir rod is a rational development and the development of all human civilizations. Its generation makes everyone no longer worry about petir strikes on buildings. It is very effective in maintaining the safety of buildings and people themselves. Second, the effect of petir rod. To put it bluntly, we can understand that the petir rod is a device that prevents petir strikes in buildings. Many multi-storey buildings have petir rods, but many friends do not know the basic principles of petir rods and how to avoid petir strikes in buildings. Traditional petir protection can be divided into anti-shock petir, anti-magnetic induction petir and comprehensive petir protection. The petir protection grounding equipment for shock and petir protection is generally composed of three parts, namely the petir strip, the wire and the grounding body; the petir protection strip is divided into petir rod, petir protection wire and petir protection net. The basic principle of petir protection with the petir rod as the petir strip is: the petir rod is connected to the ground according to the transmission line, and has an equal phase difference with the floor, making full use of the relative height to increase the magnetic field strength to the specified value. correctly guide the charge and discharge. The petir rod causes electrostatic induction under the action of a strong electrostatic field, leading to upward charging and discharging; the two move forward to generate a petir safety channel, and then pour into the ground to achieve the actual effect of petir protection. In essence, the petir rod is a kind of petir rod, which can cause the surrounding petir, charge and discharge in advance, and transmit the petir current to the road surface according to its own grounding device electrical conductor, so as to avoid the maintenance target from being struck by petir immediately. 3. Lightning rod installation standards. Lightning rods are used to prevent petir strikes in buildings, so the installation and use of petir rods should be very standardized. Only the installation and use of the petir rod can fully exert the petir protection effect, so the installation of the standard petir rod is very important. 1. The concrete base should be poured concrete at the installation site in advance, with a size of 400mm × 400mm × 600mm (length X width X height), and pre-embedded anchor screws or plastic expansion screws. 2. Install the petir rod. The petir rod base is fixed on the pre-set prefabricated concrete base. The petir rod tower base is reliably connected with the concrete base anchor screw (or plastic expansion screw). 3. The petir rod wire connector must be reliably connected with the power grounding wire, the wire connector is light green, and the cross-section BVR25mm2 or more copper core wire.
