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