Yes. At the point of contact between the line of fire and the ground, an electric field will be formed with this point as the center of the circle, and from the center of the circle outward, the voltage will gradually drop, and every two points, a voltage will be formed, so that when a person walks, a step voltage will be generated before each two points.
As a result, a voltage or current will be formed between the feet of the human body, and an electric shock accident will occur when the voltage value or current value exceeds the safety value of the human body.
To prevent the harm of step voltage to the human body, the following should be done:
First, stay away from the firing line. Do not go close to the high-voltage line that has fallen to the ground.
Second, when you have to pass through the area, you should walk on one foot or jump on both feet.
Third, it should move away from the center and not in the opposite direction.
Fourth, wear shoes with insulated soles when passing UHV.
Still dangerous, there is a risk of arc electric shock.

A leakage of electricity from a fire wire on damp ground will surely electrocute a person. This is because the live wire is electrified, and an electrical circuit is formed when the fuse comes into contact with the earth. Wet ground is a good conductor and there is a risk of electric shock when people come into contact with it.
In the case of high voltage, step voltages may also be formed. That's even more dangerous.
-
This is a very serious question, the answer is yes, as long as people are under the condition of poor insulation protection, people will become conductors between the wet ground and the leakage of the live wire, the probability of electrocution is quite large, remember, immediately eliminate potential safety hazards, life is only once, absolutely can not let this safety hazards happen around us, especially the elderly and children must have a sense of safety.
-
The conductivity of the wet ground is high, so the fire wire leaks electricity on the wet ground, and people are easily electrocuted on the wet ground.
-
The live wire voltage of the mains is low, and it is generally not in direct contact, but it is different if it is a high-voltage line, and the step voltage will also cause an electric shock accident.

Summary. Hello, I am glad to answer for you: a live wire can leak kilowatt-hour electricity for a day, a live wire leakage voltage is 220V, the live wire grounding is a short circuit, at this time the current is the maximum, but there is a leakage protector, the current between the live wire and the ground wire will trip.
Hello, I am glad to answer for you: a live wire can leak kilowatt-hour electricity for a day, a live wire leakage voltage is 220V, the live wire grounding is a short circuit to sell the thick sell Sun, at this time the current is the largest, but there is a leakage protector, the current between the live wire and the ground wire will trip.
Related information: live wire leakage means that in the process of normal transmission of current in the phase wire, due to the destruction of the insulation layer somewhere, the current in the circuit may be quietly returned from there. For example, it is connected to the earth or some other metal material.
Just like the metal casing of the household appliances in our home has electricity, it is all due to this reason. =
-
The fire wire at home leaks on the wet ground, which will cause tripping, and the regular family distribution box will be installed with a leakage circuit breaker, except for the use of Ming Hu Fei in accordance with the safety regulations, it is inevitable that the accident will occur. Slam on.
-
Yes, the line of fire is a potential difference, that is, the voltage, and its stuffy performance can press the electrons into the wet ground, and the same wet ground can also press the electrons into the body of the person located in it, so that the body is in a state of high potential and the person in the mask dies.
-
Absolutely! The voltage of the live wire is 220V, the safe voltage of He Ze in the dry environment of the human body is 36V of Liang Xin, and 36V in the humid environment is likely to threaten personal safety (the physique of the human body is different) 220V can definitely electrocute people!
-
Possibly, the voltage of the live wire is 220 volts, if the ground is wet, the leakage of the live wire is likely to be life-threatening, and it should be dealt with as soon as possible.
-
When the human body is energized, the resistance of ordinary people is generally about 5000 ohms, and the range is between 3000 ohms and 8000 ohms. Individual differences are greater. When the average person is sick (such as a cold), or the weak person has a small resistance value, generally more than 3000 euros.
And people with good physical fitness will have 8,000 euros or even some as high as 1m euros. The passing voltage and the resistance of the human body can roughly calculate the value of a land current passing through the human body. According to the test results, when the current passing through the human body exceeds 50 mA seconds, it will cause irreversible damage to the human body's functions.
In other words, if an electric current of 50mA passes through the body for more than a second, it will cause organic damage or even death to the person. Then according to the ordinary resistance, the electric shock is about 44mA current. So there is danger after a hail for more than a second.
In general, more than a second can cause unpredictable damage or death. The risk of electrocution will also be greater for the frail and sick, especially on the wet ground.
-
This situation is a great safety hazard, as for whether the person can be electrocuted depends on the insulation of the person to the ground, such as wearing dry shoes may not be too big, such as the shoes are more humid and disturb the cover or the sole is damaged, it is very dangerous, and the electric shock part of the body is also very related!
-
In this case, it is very likely that the person will be electrocuted, because the dampness of the ground will increase the conductivity of the human body and the earth. If you find that there is leakage, you should turn off the power in time.
-
I'm leaking electricity on the wet ground now, will it be when the electricity is there? I think that the rocket leaks electricity on the wet ground, which will be ignited by those who do not care about it, because its voltage is not so high, but it will have a numb feeling.
-
Of course, there is such a danger, so if this situation occurs, it must be dealt with as soon as possible, after all, safety comes first.

The wire itself is electrified, it is not in contact with the earth, and there is a voltage of 220 volts between it and the earth. But the metal iron.
is electrically conductive, it conducts electricity.
Gone, the current passes through the iron, and the conductivity of the iron is better than that of the human body, so the current passes through the iron and not from the human body, so it will not electrify the person.
When we talk about electric shock in humans or animals, we actually mean that an electric current passes through the body of a person or animal (plants, bacteria, and viruses will not be electrocuted). The wires that lead out of the power plant are usually four, and one is connected to the earth, which is called the ground wire; The other three are not connected to the earth and are called the wires of fire. However, there are generally only two wires introduced to individual users, one is the live wire and the other is the ground wire.
Light bulb. There are two contact points on the lamp head, one is connected to the live wire, and the other is connected to the ground wire, and the electricity should come from the live wire, through the filament, and then go back from the ground wire or the earth, so on. The light bulb will come on.
If one contact point is connected to the live wire and the other contact point is not connected to the wire, then there is no way for electricity to go, the current cannot pass through the filament at all, and the bulb does not light up.
If a person touches a line of fire and the person is standing on the ground, an electric current can pass through the human body and an electric shock accident occurs. The reason why swallows stand on high-voltage wires and do not get electrocuted is because they only touch one live wire, not the other ground wire, and they are not standing on the ground, so there is no electric current in their bodies.
-
If the live wire touches the iron, there are insulators all around, only the iron is charged, and there will be no leakage, if the iron is next to the conductor, such as, earth, water, other conductors, leakage, the zero wire itself is not charged, usually there will be no leakage, if it comes into contact with the conductor is still very dangerous ,...

Summary. The fire wire at home leaks on the wet ground, which will cause tripping, and the distribution box of the regular family will be installed with a leakage circuit breaker, unless it is not used in accordance with safety regulations, it is inevitable that the accident will occur.

There is no leakage protector for the light wire.
You're not professional.
Many people think that the probability of lighting leakage is relatively small, so there is no installation regulation to install leakage protection. Although the current of the lighting line is not very large, because there are still a lot of lighting wires at home, if it is installed in a place that can be in direct contact with the human body, it is best to connect it to the ground wire or install leakage protection. In this way, it can also play a certain role in security.

<> first case: A is standing on an insulated wooden bench and touches the fire wire with one hand and the neutral wire with the other. In this case, there will definitely be an electric shock, but the leakage protector will not trip, because the human body does not touch the earth, and there is no leakage of electricity in the reed.
The second case: Trembling Grip B stands on the ground and one hand touches the line of fire, at this time the person will be electrocuted. If the leakage current does not reach 30 mA, the leakage protection will not trip, and the minimum leakage protection starting current for household use is 30 mA.
Because most of the shoes are insulated, but the insulation effect is not very good, so the hand touches the fire wire and has the feeling of electric shock, but the leakage current does not reach the jumping standard, in this case people can break free.
-
If the body parts are not in contact with electricity, and then the fire wire touches the orange and the zero line will cause the switch to jump to call the Wusun gate, and this is also a very dangerous thing, the square should be especially careful not to let this situation and chain things happen!
-
Summary. If you double touch the line or the ground is damp, it will kill people.
If the live wire and the neutral line fall to the ground, will the fire wire be electrocuted and the leakage will not electrocute passers-by.
If you double touch the line or the ground is damp, it will kill people.
If the ground is dry, people are not small: if you touch it, a live wire will not be electrocuted, and the air switch will not trip.
If you only touch one line, there will be something wrong with zero, and there will be something wrong with the line of fire.
The zero line is fine, the line of fire will die.
If the hand touches the live wire, will the air switch trip, will it electrocute people?
Won't trip, all very dangerous.
If the current is too large, it won't trip.
Will the leakage protection switch trip.
Depending on the degree of dust grounding, if the ground is relatively dry, or not very wet, and the capacity of the empty opening is relatively large, it will not trip early. This is related to the problem of ground resistance, because the resistivity of the soil is different in different places. It is also related to humidity and other conditions.
Don't try.
Spare parts or machines, there is a possibility of failure, so the focus should be on the probability of damage, Borui GE has been on the market for several years, from the market feedback, basically did not see Borui GE battery damage related information, after all, for hybrid models, the battery is a very core component, quality control can not be sloppy. The new energy vehicle battery is a little expensive, Borui ge is no exception, often proportional to the quality, cheap battery quality is difficult to be guaranteed, the first is not easy to damage and other problems, the subject can rest assured.
The concept of artificial intelligence has greatly surpassed the concept of industry, it is a collection of problems such as imitating and studying human intellectual activities such as decision-making, optimization, control, learning, planning, and collaboration, and almost all industries can and can have close connections. At present, the so-called artificial intelligence promoted by some enterprises and products is just the most simple computer application technology that is the easiest to implement in this concept, but wearing an artificial intelligence vest immediately looks tall.
Maybe everyone will have their own place to shine, just like the Yi at the beginning! Everyone is always a mixed bag! First of all, let's analyze Sun Yue with my own feelings. >>>More
It should all be there!
In 1790, there was a Frenchman named Sifrak, who was particularly fond of using his brains. One day, he was walking on a street in Paris, because it had rained the day before, and there was a lot of rain on the road, and it was very difficult to walk. Suddenly, a four-wheeled carriage rolled from behind him, the street was narrow, and the carriage was wide, and Sifrak ducked but was not knocked over, but was splashed with mud and rain. >>>More
