electricity is inseparable from our daily life. It is inseparable from mobile phone charger and large to urban construction. Electricity is transported by a "grid" composed of low -voltage lines, and transformed stations of low -voltage lines. The most common in the "grid" is the high -voltage line, which is the wires on the "iron tower". While the electricity brings us convenience, it is very dangerous because of its huge energy. Everyone knows the danger of home electric shock. So do you know the harm of high -voltage electrical transmission line electric shock and how to stay away from high -voltage electricity? The voltage level of
in my country is generally 35kV, 110kV, 220kV, 330kV, 500KV, 750KV, etc. 110kV and 330kV are mostly used in the northern region. Generally known as the transmission voltage below 220 kV is called high -voltage transmission , 330 to 750 kV transmission voltage is called ultra -high voltage transmission, and transmission voltage of more than 1,000 kV is called U. Even if the low -level high -voltage electricity is reached, it is very very dangerous. The possibility of surviving is very small. I have heard that one meter eight people will be beaten one meter and five! Intersection So how far we have so many levels of high -voltage electricity is safe? It is 1 meter away, 2 meters away, or 3 meters far ... I don't know if it is really dangerous! After watching the following content of
, everyone is at ease ...
is transmitted underground underground in cities that high -voltage power transmission is generally used in the city. As long as the safe construction plan is regularly operated, there will be no problems. We focus on the safety of high -voltage lines transmitted by an overhead line carried by the tower in the wild. Based on - State Grid Corporation "Power Safety Work Regulations" power line part (trial), State Power Grid Security Supervision [2005] No. 83 specifications, 10kV and below are 0.70 meters, 20 and 35KV safety distances are the safety distance of 20 and 35KV is the safety distance of 20 and 35KV. 1.00 meters, 110kV safety distance is 1.50 meters, 220kV safety distance is 3.00 meters, 330kV safety distance is 4.00 meters, and 500kV safety distance is 5.00 meters. The judgment of the voltage level is generally obvious on the electric tower . Of course, if we can't visually, the farther the high -voltage line is better.

may be asked here. Sometimes when I walk under the high -pressure line, I will hear the sound of nourishing when I walk under the high -pressure line. So what's going on?
High -voltage line will form a strong electric field around the wires, so that the air will be ionized and the electric discharge will be formed. So, when you hear the sound of "嗞嗞嗞" next to the high -voltage line, don't doubt it, it is discharge! Moreover, the higher the voltage level, the stronger the electric halo, the greater the noise. At night or rain and mist, near 220 kV and 500 kV high -voltage transmission lines may also observe a faint blue -purple halo.
In short, for everyone's safety, stay away from the high -voltage line!
