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