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