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