Why doesn t the zero line electrocute people, does the zero line electrocute people, why?

The 220V mains we use is AC power, and the entrance to the house is two wires, which form a circuit with the load. The currents in the two wires vary from time to time, but are equal everywhere.

Since the power plant connected one of the two wires to the earth, it was named the "zero line" and the other "fire line". In this way, the potential difference between the "zero line" and the earth and the "live wire" is 220V AC.

Our human body stands on the earth, and the earth is equipotential, so the potential difference with the "zero line" is also 0, and the hand touching the "zero line" will not be "electrocuted", which is what people say "uncharged".

In general, the potential of the neutral line is relatively low, so it does not electrify people.

However, in some special cases, the potential of the neutral line is enough to cause harm to the human body, and even that dangerous situation may last for a long time. Be careful!

Neutral line (N): Mainly used in the working circuit, the main line is drawn out after the neutral point of the transformer is grounded. The potential of the neutral line is zero, and the voltage between the neutral line and the ground is 0V, so there will be no electricity to people. Got it?

Three-phase balance, the zero line has almost no current, and the zero line is grounded, and the electricity is directly directed to the ground. However, some enterprises have poor three-phase balance and are not grounded, and the zero line still has current, which will electrify people.

1. The phase wire is nothing more than the live wire used by residents, with a line voltage of 220V; Or two-phase wires for general industrial electricity, with a phase voltage of 380V, they have a voltage of 220V or 380V to the ground. The neutral line is grounded through the neutral point, that is, the voltage to the ground is 0V.

2. In order to make the alternating current have a very convenient power conversion function, usually the industrial electricity adopts three-phase sinusoidal alternating current, and the current phase (reflecting the direction of the current) is 120 degrees different from each other. Usually we refer to each of these wires as phase wires (live wires).

3. The neutral line is the line drawn from the neutral point on the secondary side of the transformer, which forms a circuit with the phase wire to supply power to the electrical equipment.

The neutral line is not necessarily not electrified, it depends on whether the neutral point of the transformer is grounded, if it is not grounded, then the neutral line and the ground are not equipotential, and it will be electrified.

Hello: The zero line is a wire without electricity, of course, it is not electricity.

Hope mine is helpful to you, good luck!

The neutral line has a ground row on the transformer side and communicates with the earth.

It's the line of fire that electrocuts people.

1. Because the person and the neutral line are grounded, the person and the neutral line are at the same potential, and there is no potential difference between the two. There is no voltage, so there is no current between the two, and naturally it will not die.

2. If the person is not on the ground, but as long as the person touches the zero line, the person will be grounded, and the electricity will not die. The key is to have a potential difference and voltage before it can electrocute a person.

3. If the person only touches the fire wire, and the rest of the human body does not touch other things, then the person is not in danger, because at this time, the person and the fire wire are equal potential, and there is no voltage and current. When one part of the human body touches the live wire and the other part touches the neutral line, there is a voltage of 220 volts between these two contact points, and there is a large current flowing between these two points, and people are in danger.

4. But it is not necessarily dead, for example, the two contact points are the feet and knees, and the person's calf will be reimbursed, but the person will not die, because the current basically does not pass through the important heart and brain.

If the zero line is open, it will also electrocute people. Because electric current will pass through the body, as long as the current flowing through the body exceeds the minimum allowable bottom line, the person will be electrocuted.

Yes, the neutral wire is the circuit of the live wire, but the chance of being electrocuted by only touching the neutral wire alone is very small, about 80%, and the live wire is as high as 99%. The neutral wire is a single electrode with the smallest voltage, and the general electrolytic capacitor cannot store electricity, while the live wire can use the electrolytic capacitor to store the left and right electric energy if the current is large. It can electrocute people because the voltage flows to the ground through the heart to form a circuit, and the neutral line forms a circuit, so the voltage is small, so it can electrocute people, but for an adult, there is a chance to escape within 10 seconds.

The neutral line will not electrocute a person because the neutral line has a voltage of 0v to ground, so it will not. However, in actual use, we should also regard the neutral line as having electricity, because we are afraid that the fire wire will turn the neutral line into a live wire through electrical equipment.

Under normal circumstances, the zero line should not be electrified, so under normal circumstances, touching the zero line will not be electrocuted, but if the end of the zero line is not in good contact, or the zero line current is too large, a certain voltage will be generated on the zero line, and even in some places where the electrical environment is complex and the wiring and grounding are not standardized, the zero line will show a voltage of up to 50V, which has exceeded the safe voltage of 36V. This creates a circuit that can cause harm to the human body.

If you just touched the zero line. It shouldn't be electrocuted by e-commerce.

No, only the firewire will electrify people.
