1. Safe distance - I hope everyone pays attention when encountering high voltage lines in the wild. If they don't see it, the farther the better. 10KV and below - 0.70m · 20, 35KV - 1.00m · 66, 110KV - 1.50 m·220KV——3.00m·330KV——4.00m·500KV——5.00m (according to – State Grid Corporation “Electric Safety Work Regulations†Power Line Part (Trial), State Grid Safety Supervision [2005] No. 83) The minimum vertical distance between the conductors of the 220kV overhead transmission line and the building is 6 meters, and the minimum distance between the side conductors and the building is 5 meters (the distance between the conductor and the urban multi-storey building or planned building refers to the level distance). 2, how to judge the voltage level is more professional is to look at the tower, wire, insulator form, etc. The easiest way is to look at the tower markings at least in Beijing: 3. Changes in safety distance The above safety distance is under normal weather and normal conditions, but the actual situation may be more complicated and more hidden. For example, trees are too high, too close, such as special terrain such as narrow mountain passes, such as human special behaviors.甩 fishing rods, kite flying, climbing towers - including the rabbits pointed by the trekking pole! ! ! 4, the process of electric shock High-voltage electricity has different situations for people, 5, the judgment of electric shock can be seen from the above, But be careful: Wifi Dongle,LTE Wingle,LTE Dongle,Sim Dongle Shenhzhen Tongheng Weichuang Technology Co., Ltd , https://www.thwclte.com
The electromagnetic radiation intensity of the 220 kV high-voltage line in the range of 100 meters exceeds 0.4 micro-tesla; experts believe that the magnetic field safety value generated by the high-voltage line is 0.4 micro-tesla (μt), above which the child will face illness. risk.
Safety is relative, and more or less time will cause harm to the human body.
·Written with "50XX" is 500KV
· 220KV written with "22XX"
·Written with "11X" is 110KV
·Written with "3X" is 35KV
—— Relatively the most dangerous is the 35KV line, because in Beijing, especially in a few suburbs such as Mentougou, Haidian, Miyun, Huairou, etc., some 35KV lines remain neutral grounded, which is more dangerous to people than other higher voltage grades.
· For example, the special case of the high voltage line itself - such as wire breakage, such as wire breakage and grounding, such as lightning strikes (lightning strikes, lightning strikes)
· Of course, there are changes in the weather. . .
In short, even professionals in the power industry must be vigilant at all times.
· For example, hitting (flying out, as long as it doesn't fall, it won't burn)
· For example, electric shock (similar to thunder, can make a hole in a certain part of the body)
· The rabbit's vivid and cruel description is an electric burn. After a long time of electric shock, it can't be undone and can only be burned dry. . .
———— Therefore, the degree of damage caused by high-voltage electricity to people is mainly at the time of contact – in fact, (Beijing) is currently damaged by wires, and the high-voltage line is very small because: 1. It is far from the active area, 2, 110KV At the beginning, there is a perfect "relay protection". As long as someone gets an electric shock and trips within 1 second, the power will be cut off. If the person does not leave, the top will automatically power off again after the multiple times - so the person is shocked twice more times. It may be hit and injured, and will not be burned continuously. The most harmful to people is 35KV and below. Because of the neutral grounding method, people will not automatically trip after electric shock (only abnormal voltage signal is emitted). ), if the human body can not be separated, then it is the real slow burning. . .
Electricity is very dangerous, but high-voltage electricity is no more dangerous than low-voltage electricity. Beijing dies every year at 10000V, 6000V, 380V, 220V. It is not much in my work that really dies at higher voltage levels. Was hit by 110KV voltage, but also experienced the 110KV tower in operation was dumped and dismantled by the life, and the real death of electricity is basically 10KV and below. As for the high voltage line in the outdoor, Normal walking has no harm to people (the theory of electromagnetic radiation has been denied by scientific research departments, environmental protection departments, and the judicial department. Only some real estate developers are secretly provoke residents to make trouble)
· Do not do special movements that may cause tip discharges - climbing, raising metal objects ( trekking poles, fishing rods, kite lines, etc.)
· Pay attention to special terrain - narrow mountain pass, too high trees (high pressure corridors will be regularly carried out to go to the tree)
·Special climate - the rabbit has said · special signs - such as snoring or snoring (may be the sound of high-voltage discharge), hats, fingers appear halo (you can't see it, you may be Occasionally see) or sparks in the sharp part of the discharge (do not have to wait for rain, this is a common phenomenon in the large substation equipment area)
—— At this time, you must not panic and run, lest you run closer and closer; you must not rush to escape, there will be striding voltage; you must not easily rescue each other, each person's potential is different, close to each other is more dangerous! ! ——You can only see the dangerous direction (high-voltage line, especially the position of the broken line and the grounding line), and then slowly retreat in small steps. Others can use long insulating objects while ensuring insulation. Help him.
