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