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