So a lot of people say, well, what's the current when lightning is so bright? Why is it so bright? What if there were no lightning rods? How powerful are lightning rods? And so on and so forth and so on and so on and so today we are going to talk to you about the electrothermal sink when is it going to rain? Lightning and thunder tell us that if there is already a lot of water vapor in the air that has condensed into water vapor, it's a sign that rain is likely. When is it going to rain? When positively charged and negatively charged rain clouds rub against each other in the sky, lightning is generated, just like wearing a cotton-padded jacket in winter, when you take it off, there is static electricity。
So a lot of people ask: Why do our parents tell us to turn off our appliances and TVS when it's thundering? Does our district have lightning protection device? Electric heat collects tell you: the area does not have lightning rod to be unable to pass acceptance check and undertake selling so need not worry! And why do some homes turn off appliances? Because some floor is taller, can lead electric, as to the house of a few bungalow and country, it is general shorter, generally speaking, although thunder also does not matter, tall floor or object of height lead thunder to go but! For external TV antenna satellite receivers, it is important to unplug the power supply when lightning strikes, because such objects are more vulnerable to lightning strikes, although household appliances can be used in buildings with lightning protection。
But there are two caveats: 1 thunder when had better not use mobile phone 2 second, do not use the installation position of solar water heaters because solar water heater in general than in the roof of the lightning rod, it is easy to become the target of a lightning strike 3 indoor lightning prevention, the television outdoor antenna in the thunderstorm day away from the TV, and connected to the ground, should shut the doors and Windows, prevent spherical thunder into indoor harmful. 4 When thunderstorm, the human body had better leave the line that may transmit thunder wave to invade and equipment 1.5m above, that is to say, do not use electric equipment temporarily as far as possible, had better unplug power supply plug, do not make a phone call, do not close to indoor metal equipment, if radiator come from water pipe downpipe; Want to leave power line telephone line broadcast line as far as possible, in order to prevent these lines and equipment to the second discharge of the human body 5 do not wear wet clothes, do not close to the damp wall above is today electric heat sink to bring about the Oriental Pearl is struck by lightning, how much current? Will hitting the neighborhood affect home appliances? In detail, the comparison of security issues is the top priority, so everyone is bound to avoid these problems
