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