Sò un fermu credente chì tutti sanu lampu rods. When we were in junior high school, the textbook covered it in detail. In our daily life, we often see lampu rods at the top of multi-storey buildings and have the effect of maintaining buildings, but many people have little knowledge of lampu rods. Now let us know with you who invented lampu rods, lampu rods and the efficacy of lampu rod installation standards. 1. Who invented the lampu rod. The invention of the lampu rod has a good effect on preventing buildings from being struck by lampu. Nowadays, there are more and more multi-storey buildings in life, and the use of lampu rods is also more common. As everyone knows, many friends do not know who invented the lampu rod. Who invented the lampu rod? American scientist Franklin invented the contemporary lampu rod. Franklin felt that lampu was a charge-discharge condition. To better prove this, on a stormy day in July 1752, at the risk of being struck by lampu, 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 lampu 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 lampu was relatively poor, and Franklin was not injured. The invention of the lampu rod is a rational development and the development of all human civilizations. Its generation makes everyone no longer worry about lampu strikes on buildings. It is very effective in maintaining the safety of buildings and people themselves. Second, the effect of lampu rod. To put it bluntly, we can understand that the lampu rod is a device that prevents lampu strikes in buildings. Many multi-storey buildings have lampu rods, but many friends do not know the basic principles of lampu rods and how to avoid lampu strikes in buildings. Traditional lampu protection can be divided into anti-shock lampu, anti-magnetic induction lampu and comprehensive lampu protection. The lampu protection grounding equipment for shock and lampu protection is generally composed of three parts, namely the lampu strip, the wire and the grounding body; the lampu protection strip is divided into lampu rod, lampu protection wire and lampu protection net. The basic principle of lampu protection with the lampu rod as the lampu strip is: the lampu 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 lampu 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 lampu safety channel, and then pour into the ground to achieve the actual effect of lampu protection. In essence, the lampu rod is a kind of lampu rod, which can cause the surrounding lampu, charge and discharge in advance, and transmit the lampu current to the road surface according to its own grounding device electrical conductor, so as to avoid the maintenance target from being struck by lampu immediately. 3. Lightning rod installation standards. Lightning rods are used to prevent lampu strikes in buildings, so the installation and use of lampu rods should be very standardized. Only the installation and use of the lampu rod can fully exert the lampu protection effect, so the installation of the standard lampu 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 lampu rod. The lampu rod base is fixed on the pre-set prefabricated concrete base. The lampu rod tower base is reliably connected with the concrete base anchor screw (or plastic expansion screw). 3. The lampu 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.
