With the changing times, electricity has become a part of our lives and exists in every corner of our lives. We have become so accustomed to it that we have gradually forgotten how much harm it can cause us...
I think everyone should have some understanding of the principle of electrocution. When an electric current of a certain intensity passes through the body, it will cause stimulation of various tissues in the human body, causing them to lose their normal functions and causing breathing or heartbeat to stop. If it is high voltage, it will cause heat and burns...
But since we rarely come into contact with energy sources in our lives, there is usually a leak protector. , the word “electrocution” has therefore always been relatively distant from our lives. However, according to surveys, thousands of people still dieore every year due to electrocution accidents in China, but compared to the millions of accidental deaths, this ratio is indeed not easy to attract people's attention...
Therefore, heavy rain The horror is not only that it will cause flooding, but also because we cannot predict the conditions in the water. In addition to sewers without manhole covers, there are also deadly currents that are not visible to the naked eye...
But everyone There is no need to panic because of this. After all, electrocution in water does not happen so easily. First of all, leaks are not common and flooding is even rarer. However, we never know which will come first, tomorrow or the accident. Therefore, in order to avoid bad luck, it is best to pay attention to some things in heavy rain to avoid unnecessary injury.
The safety distance depends one voltage, equipment type, installation method, water purity and other factors. According to different conditions, the distance is also different.
The higher the voltage, the greater the safety distance. Water has resistance, and the higher the purity of the water, the higher the resistivity. However, water is generally not very pure and is therefore generally considered conductive. Especially during floods there are many impurities. In addition, the cross section of the water is large and the length is limited, so there is no safe distance. Any leak less than 20 meters is dangerous. Under no circumstances should you enter water with a voltage of 220 V.
