Nani aligundua fimbo ya umeme Kazi ya fimbo ya umeme Mahitaji ya vipimo vya ufungaji wa fimbo ya umeme

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