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