How can you touch the fire wire without being electrocuted! 5

There are only 2 possibilities for touching the line of fire without being electrocuted.

First, your insulation is good, that is, your shoes are high-strength insulation, or your feet are stepping on non-conductive materials, such as plastic, wood, paper and other insulating materials.

Second, there is no power supply or the voltage is low, and the switch may not be closed, or it may be below the safe voltage of 42V.

Friends, don't touch it knowing it's a line of fire, you can't see or smell electricity, it's not a joke, please pay attention to your life safety.

Pure hand typing, I hope it helps you, hope, thank you.

As soon as you stand on the ground, you will be electrocuted. Reason? Because the human body is a conductor.

The current can be passed. Even if you have two feet, then electricity will pass through your feet (whether you are apart or not) and into the ground. The bird is not electrocuted because it does not touch the ground.

If you have one foot on the ground. It's just as electrocuted. If you are holding the line of fire with both hands hanging.

You won't be electrocuted. If you stand on one foot, pass on one foot! If you are electrocuted with one hand.

Burn your hand first. If you keep getting electrocuted. Then your whole body including the internal cataracts are injured!

1.Wear insulated plastic shoes.

2.Insulating gloves for electricians.

3.Both hands touch the line of fire at the same time.

4.only on a dry wooden bench.

In short, it is enough not to form a closed loop.

Isolated from the ground with one hand and footFor example, stepping on a wooden bench, etc.

It's okay to keep your feet off the ground. 100% OK

You think you can fly? Or you have people drop you up! Fool around!

Tear down the line of fire, touch it as much as you want, why do you still have this habit.

Because when we stand on an insulated stool and touch the live wire, because the human body is insulated from the earth, we have the same potential as the live wire, and there is no potential difference in the voltage will not be generated.

There is no circuit between the live wire and our body and the transformer, so there is no current passing through our body, so there is no electric shock. Let's look at the circuit diagram of a light bulb that lights up.

Probably, if one hand touches the live wire and the soles of the feet are not insulated, you will definitely get electrocuted. As long as there is no circuit with the wide paulownia earth, it will not be electrocuted, which means that standing on a wooden stool is a good pants with no problem. Therefore, this operation needs to be done with caution.

Electric shock is a common name for electrical injury, which usually refers to the tissue damage and dysfunction caused by the human body directly touching the power supply or high-voltage electricity passing through the human body through air or other conductive media to transmit the current through the human body, and in severe cases, cardiac and respiratory arrest occur. High voltage voltages above 1000 V (volts) can cause burns. Lightning damage (lightning strike) falls under the category of high-voltage electrical damage.

When the human body is exposed to electric current, the mild person immediately appears panic, sluggishness, paleness, muscle contraction at the contact site, and dizziness, tachycardia and general fatigue. In severe cases, coma, persistent convulsions, ventricular fibrillation, and arrest of heartbeat and breathing may occur. Some people with severe shocks have symptoms that are not severe at the time but suddenly worsen after 1 hour.

Therefore, the following precautions should be taken to prevent electric shock:

1. To prevent electric shock and short circuit;

Second, pay attention to the switch to control the live line;

3. It is best not to connect the fuse on the zero line;

Fourth, the center of the lampholder is connected to the fire wire;

5. Do not mix the grounding wire and the neutral wire;

Sixth, the electrical appliances are cut off, so that the electrical appliances will not be electrocuted, and if the zero line is broken, the electrical appliances will be electrocuted.

Because electricians come with insulating gloves and a range of insulating products.

The iron suit (isotope electrical suit) worn by the electrician applies the electrostatic shielding phenomenon in physics: (putting the electronic instrument into the metal spherical shell can avoid the interference of the external electric field on the electronic instrument, which is also limited), the strong current in the wire will cause the conductor to produce magnetic electricity, wearing this can make the iron cloak weak current but not fatal, to avoid human conduction.

Because you are standing on the ground, the neutral line has a "zero" voltage to the ground and cannot produce current. The fire wire has a very high voltage to the ground, so the current will flow from the fire wire through the human body to the earth. If you are standing in the line of fire (like a bird), then touching the line of fire will not be electrocuted, while touching the neutral line will be electrocuted.

There is no voltage in the grounding of the neutral wire, so only contact the neutral wire without electrocution, the circuit you said, you connect the live wire with one hand, and connect the zero wire with the other hand will also be electrocuted, because there is a voltage between the live wire and the neutral wire.

Figuratively speaking, you will understand that the earth is regarded as the negative pole of the power supply, and it is connected to the zero line. The live wire is connected to the positive pole, so when you touch the live wire, and you have to connect your feet to the ground, you are equivalent to connecting the positive and negative poles, and you are equivalent to using electrical appliances, that is, like TVs and refrigerators, in parallel in the circuit. Touching the zero line is equivalent to connecting in parallel with the wire, your resistance is greater than the wire, and the current must go through the wire.

Because the live wire has a voltage of 22ov to the ground, when the human body touches the live wire, the current flows back from the human body to the earth, and when the current through the human body is large and 50mA will cause harm to the human body. The zero line is equipotential to the earth, and when the human body touches the neutral line, no current passes through the human body, so it will not cause harm to the human body. When the live wire is connected to the neutral wire (the metal part), it will cause a short circuit, causing the upper level switch to trip.

At this time, the live wire will not be electrified, and if there is an insulating material between the live wire and the neutral wire, contact with the live wire will also cause an electric shock.

The safety voltage of the person is 36V, U=IR, which can obtain a safe current load, and the wire will have current through. The neutral line also has current.

1. You stand on the ground and touch the live wire with one hand, and you, the person with resistance, and the load in the line are connected in parallel.

The current you get is big and deadly.

2. You stand on the ground and touch the zero line with one hand, and you, the person with resistance, are connected in parallel with the line (at this time, the wire also has an R value, which is very small).

The current you get is small and not lethal.

For example, if you are looking for someone to carry the pot, 1, you are touching the line of fire, and you are helping the load to carry the pot.

2. You touch the zero line, and the equivalent small resistance value of the zero line is helping you to carry the pot.

Whoever has a small resistance will take the blame.

Because electricians come with insulating gloves and a range of insulating products.

The iron suit (isotope electrical suit) worn by the electrician applies the electrostatic shielding phenomenon in physics: (putting the electronic instrument into the metal spherical shell can avoid the interference of the external electric field on the electronic instrument, which is also limited), the strong current in the wire will cause the conductor to produce magnetic electricity, wearing this can make the iron cloak weak current but not fatal, to avoid human conduction.

Because they wear insulated gloves.

The resistance of a good insulating pad is very large, usually more than 1m ohm, the relative ground voltage of the low-voltage circuit is usually 230V, people stand on the insulating mat (the resistance of the human body is negligible for one or two thousand ohms), and the leakage current flowing through the human body will not exceed milliampere, and there is no harm to the human body.

Electricity doesn't have to come into contact with it to get you, air can break down. If it's just ordinary voltages of 220 and 380, then yes, vacating (or standing on an insulator such as a wooden bench) and only grabbing fire or zero will not be electrocuted.

If it's not necessary, don't touch it, in case something happens, although the chance of being electrocuted is not large, but the 1 10,000 is also unbearable for you. Don't touch the wires just to pretend to be in front of others.

In fact, when dealing with low-voltage circuits, experienced electricians often put an insulating board under their feet, and they will not be shocked if they accidentally touch the live wire while working. Another example is that some leather shoes with some insulating ability can also play the same protective role.

Because there is insulated equipment and the system is trained to know how to use electricity safely, there will be no electric shock.

When operating high-voltage equipment, electricians must use auxiliary insulation safety equipment (insulating gloves, insulating shoes, insulating pads and insulating tables). Wipe it clean with a clean dry cloth before use to ensure it is dry and clean. After the equipment is overhauled, it is necessary to check whether the personnel, tools, test instruments and replaced materials and accessories are complete before power transmission.

When installing the lamp, the single-pole switch must control the phase wire; The phase wire must be connected to the spring blade of the lamp head, and the lighting in more dangerous places should be controlled by a bipolar switch. In the case of local lighting or moving lights in dangerous situations such as moisture, the power supply should be supplied with a safe voltage, and a high-sensitivity leakage protector should be installed for protection under normal circumstances.

Among the people who died of electrocution, many of them were not electricians, but those who did not understand electrical knowledge but thought that they were very capable and would do it themselves, and that was a trivial matter. Some people who don't understand electrical common sense think that there is no electricity after the switch is opened, and they don't distinguish between the power side and the load side of the switch, so they fiddle with the switch.

There is a high chance of an accident when such a person goes to repair electrical equipment.

The electrician's hand is ordinary, and he is also a conductor of electricity.

Unless it is a last resort, no one should work with electricity!

The condition for an electric shock of a live wire is: there must be an electric current passing through the human body, when only one live wire is touched, the human body to the ground (or zero, or to another live wire) will produce a voltage of 220 volts, but no current through the human body, there is no discomfort.

But at this time, if he touches the earth (or the zero line, or another live wire) at the same time, the current will form a path from the electric fire wire, through the human body, the earth, etc., and the person will be electrocuted!

As I said earlier, when the human body only touches one line of fire, the whole human body carries a voltage of 220 volts, and the person standing on the ground at this time must not mention metal objects to him! Such as brackets, wrenches, etc.! Because his body touching the fire wire has a voltage of 220 volts, when someone on the ground touches his hand through the metal, the two people form a 'series' ground, and the current will flow at the same time to form an electrocution!

In the past, the electricity consumption was not standardized in the early stage, and there were such cases of double electrocution, out of 'ignorance' and 'recklessness'.

The above is just to talk about the principle of whether the 'touch the fire wire' is electrocuted**, if someone pulls someone who has been electrocuted, the same will be electrocuted at the same time!

Notice: General live work is expressly prohibited!

How to wire the live wire so as not to be electrocuted, the old electrician: the live wire and the zero wire are connected like this, and there will be no electric shock.

I think that electricians dare to touch the line because they have protective measures, after all, they are professional, so we must not touch themselves when we see others can touch them, there is danger!

Because they have insulating gloves, good insulating pads have very large resistance, usually more than 1m ohms. The relative voltage of the low-voltage circuit is usually 230 volts, and the leakage current flowing through the human body when a person stands on an insulating mat does not exceed milliamperes, which is harmless to the human body.

The reason why they dare to touch the live wire with their bare hands is because they are well insulated and grounded, and they are not connected to the earth, so the resistance is very large, and there is no current, so it is very safe.

Theoretically, it does not form a closed loop and does not conduct electricity, but this is the premise of insulator insulation and conductor conductivity, ordinary 220V you stand on a wooden stool and wear insulated shoes only pinch a single phase (although the theory is fine, it is not recommended to try to die), but the actual high voltage and so on there is such a thing as insulation breakdown.

You don't understand this, they either wear insulating gloves, or they have no electricity, or they are stepping on the template. It is easy to understand that those who know how to electrify are far away from these. But electricians have been spotted a lot.

Because the electrician himself does this business, and he has this insulating glove, don't imitate it casually, otherwise it is really easy to have problems.

It may be that the shoes are well insulated, last month I connected the machine to 380 electricity, and tightened the binding post with a wrench, and found that the binding post was actually energized.

It is not the ability to touch a single line of fire, but the ability to touch the zero line.

I asked the electrician, and they all said that they were used to hemp.

Standing on the ground and touching the line of fire will cause you to be electrocuted. The voltage of the fire wire is 220 volts, and people stand on the ground and touch the fire wire with their hands, and the fire wire, people, and the earth form a loop. The live wire is the positive pole of the power supply, the earth is equivalent to the negative pole of the power supply, the voltage between the two poles is 220 volts, and the person is equivalent to the resistance.

Does this have anything to do with the formation of loops?

The earth potential is 0, the high potential flows to the low potential, passes through the human body, and the current is large enough that the heart no longer beats. This is called an electric shock.

Power plants produce power, and we use power. In the end, the electricity went back to **, and we can all be regarded as returning to the earth.

When a power plant produces electricity (or energy), it must be the energy of something else that is converted into electricity (or energy).

So for the whole planet, the energy is constant.

As for why the earth potential is 0, it is because we define it as 0.

The amount of energy that the earth can store is almost infinite, because it is storing and releasing at the same time. It's always balanced.
