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