IEC standards.

The wire that is loaded with a multiphase unbalanced current is called a neutral wire, which is often referred to as the "zero line". It is a line drawn from the neutral point on the secondary side of the generator or transformer, and the phase wire.

It forms a circuit to supply power to electrical equipment. Normally, the neutral wire is repeatedly grounded with the PGND at the neutral point on the secondary side of the transformer.

It plays a double role of protection.

Neutral (neutral): Mainly used in the working circuit, the main trunk line that leads from the neutral point of the generator and transformer and is grounded.

Ground Wire (PE): Not used in working circuits, only as a protective wire. Using the absolute "0" voltage of the earth, when the leakage of the device housing occurs, the current will quickly flow into the ground, even if a PE line occurs.

If there is an open path, it will also flow into the ground from a nearby grounding body. (Ground from the transformer neutral.)

After leading out the main line and repeating the grounding every 20-30 meters).

1. The definitions are different.

Neutral line: The neutral line is the line drawn from the neutral point (n) on the secondary side of the transformer, which forms a loop with the phase wire (L) to supply power to the electrical equipment. Under normal circumstances, the neutral line is repeatedly grounded (PEN) with the protective ground wire (PE) at the neutral point (N) on the secondary side of the transformer, which plays a double protection role.

Neutral wire: There is a point in the winding of the transformer and generator, which is equal to the absolute value of the voltage between the external terminals, which is called the neutral point, and the wire drawn from the neutral point is called the neutral wire.

2. The voltage is different.

Neutral line: The neutral line is grounded, and the voltage is theoretically zero.

Neutral wire: The neutral wire is connected to the neutral point, not necessarily grounded, the voltage can be zero when not in use, zero when the three-phase electricity is balanced, and it is not zero when the single-phase electricity is used. When the three phases are unbalanced, it is not zero.

3. The role is different.

Neutral line: In household electricity, the neutral line usually refers to the wire drawn from the transformer grounding body, and its connection resistance has strict regulations, which must be less than or equal to ohms to ensure the normal use of electrical equipment.

Neutral wire: It is the wire that connects the metal shell of the electrical equipment with the grounding wire of the power supply (generator and transformer) as a metal, which requires the fuse or air switch in the line of the power supply to the electrical equipment, and can disconnect the circuit in the shortest time when the electrical equipment touches the shell, so as to protect the equipment and human safety.

There is no difference, the neutral line is the zero line.

The AC power cord is divided into a neutral line (the letter of the symbol is"n": neutral wire) and Firewire (marked with the letters"l"：live wire）。Electrical appliances are connected to the ground wire - the wire connected to the earth.

The live wire, neutral wire, and ground wire are all wires connected to a three-prong socket, and the voltage difference between the live wire and the neutral wire is maintained in a sinusoidal oscillating pattern. Since the ground and neutral potentials are the same, the voltage difference between the live and ground wires also remains sinusoidal oscillations.

When the human body touches the live wire, the current of the live wire flows through the human body into the earth or the neutral line, and an electric shock accident will occur, while the contact neutral wire will not be shocked.

If the shell of an electrical appliance with a conductive shell is connected to the ground wire, in the case of leakage, the current will flow directly through the ground wire to the earth without passing through the body, thus avoiding electric shock accidents.

The neutral line is grounded, and the voltage is theoretically zero.

The neutral wire is connected to the neutral point, not necessarily grounded, the voltage can be zero when not in use, zero when the three-phase electricity is balanced, and it is not zero when the single-phase electricity is used. When the three phases are unbalanced, it is not zero.

The zero line is the neutral line, which is the n line, and there is no difference. In the three-phase five-wire system, the ground wire is PE.

There is no difference between the neutral line and the neutral line.

The tail of the three-phase winding of the three-phase electrical appliance is the neutral wire, and the neutral wire is the neutral line with a wire.

The neutral line is relative to single-phase electricity, which is composed of a live wire and a neutral wire, at the transformer, the neutral wire is grounded, and the voltage of the neutral line to the ground is zero, so it is called the neutral line.

The neutral line is grounded, and the voltage is theoretically zero.

The neutral wire is connected to the neutral point, not necessarily to ground, and the voltage may theoretically be zero.

The neutral line is generally the grounding of the transformer of the substation, which is the working neutral line, and the working nature is: live wire - load - finally return through the neutral line to form a loop.

The ground wire is generally randomly grounded by the user, that is, the user's equipment is connected to the ground, which is generally connected to the metal shell, and does not participate in the circuit part in order to protect the human body from electric shock.

It turns out that there is such a big difference between the neutral line and the neutral line, and I have been working as an electrician for so many years, and I have always thought that it is the same.

The working is zeroed, and the protection is grounded.

The IEC standard refers to the conductor that is loaded with multiphase unbalanced currents as the neutral (N-wire), which is often referred to as the "zero wire".

A wire used by a ground wire to bring an electric current to the earth; When electrical equipment leaks or the voltage is too high, the current enters the ground through the ground wire.

In electrical engineering, the term grounding has several meanings depending on the field of application. Ground is a potential reference point inside a circuit. From this reference point, other potentials can be measured.

Ground can also be thought of as a common regression path for electric currents (called a ground loop or ground loop), or as a direct physical connection to the earth. Electrical engineers connect circuits to ground for several reasons: In electronic circuit theory, ground is often idealized as an infinitely charged power supply or charge absorbing slot that can absorb current indefinitely while maintaining the same potential.

The common connection point at which the head (or tail) of a three-phase winding is connected together is called the power neutral point. When the neutral point of the power supply has a good connection with the grounding device, the wire drawn from the neutral point is called the neutral line. The wire used to introduce an electric current to the earth is the ground wire.

Summary. Hello, there is a difference between the control line and the neutral line. Because the control line in the security industry refers to the line of the control loop, which is relative to the main circuit.

In general production equipment, there is always a main circuit and a control circuit. For example, a motor forward and reverse line, the main circuit is the line through which the large current passes, and the wire cross-section is relatively large, mainly through contactors, thermal relays, etc. The control loop is a button, intermediate relay, control transformer and other small currents, wire cross-section selection of a relatively small circuit, with a small current to control the large current, to achieve the purpose of starting, forward, reversing, stopping and so on.

If the control line is extended, the purpose of remote control can be achieved.

Is there a difference between the control line and the neutral line.

The neutral line is the line drawn out of the neutral point of the transformer, and the phase wire forms a loop to supply power to the electrical equipment, under normal circumstances, the neutral line is repeatedly grounded with the ground wire at the neutral point of the transformer, and the voltage is the potential difference between the two points. With voltage, electrons flow through the wires to form an electric current. It's the same as the principle that water flows from high to low.

Water does work in the process of flowing, and electricity does work in the process of flowing.

The wire is divided into three kinds: zero wire, live wire, and ground wire, and they play different roles, so you must figure it out when wiring, and you can't reverse it, or it won't bring unnecessary trouble. Let's introduce to you what is the difference between the neutral line and the neutral line.

There is no difference between the zero line and the neutral line.

The neutral wire is often referred to as the "neutral line", which leads from a transformer and can form a circuit to supply power to electrical equipment. Under normal circumstances, the neutral line is repeatedly grounded with the protective ground wire at the neutral point of the transformer, so it plays a double protection role.

Neutral line (neutral wire): It is mainly used for the working circuit, and is the main trunk line that is connected from the neutral point of the generator and transformer.

How to choose wires and debate.

1. Load power.

The cross-sectional area of copper wire and aluminum wire is the same, relatively speaking, the power of copper wire will be larger than that of aluminum wire, for example, both are square wires, aluminum wire load 2,500 watts, copper wire can load 3 kilowatts.

2. Flexibility.

Copper wire is relatively flexible in terms of performance, easy to bend, and also has the effect of anti-fatigue, but aluminum wire is different, it may break when bending, and it will be relatively hard.

3. Stability.

Aluminum wire is easy to oxidize, and the resistance is easy to become larger, which leads to the reduction of the load of the wire, which is easy to cause accidents when used, which is very unsafe, and the copper core wire has good stability and is more suitable for use.

4. Look at the packaging.

First of all, look at whether there is a certificate on the packaging, and there will be specifications, dimensions and other relevant information on the certificate, and at the same time, we should also see if there is a pre-3C certification and license, and whether the certificate can meet the standard?

5. Check the wire size.

The length can not exceed 2%, the wire diameter can not be exceeded, many lengths and cross-sections on the market do not meet the standard, special attention should be paid when choosing.

6. Look at the color of copper.

The color of the wire copper core is generally purple-red, and the gloss is better, if the color of the wire copper core of poor quality is called for the lack of purple color, it is recommended not to choose this product.

Summary: What is the difference between the neutral line and the zero line, the relevant content is introduced here, generally speaking, there is no difference between the two, both play the role of a loop. If you want to know more about related knowledge, you can consult Qijia.com.

Both neutral and neutral wires are wires in a circuit system, but their roles and characteristics are different.

A neutral wire is a wire in an AC power system whose voltage is close to zero with respect to the ground wire. In the three-phase four-wire power supply system, one of the wires is a neutral wire, which is used to connect the neutral point of each load and return the current from the load to the power supply.

The neutral wire is the connecting wire between the ground wire (PE) and the wires inside the equipment, which plays an important role in the safety protection in the event of equipment failure. When leakage occurs inside the equipment, the current will return to the grounding wire of the power supply through the neutral line, causing the short-circuit fuse to blow, and the power supply will be cut off to protect personal safety. At the same time, the neutral line can also be used to eliminate electromagnetic interference and voltage fluctuations in the power supply, and improve the use effect and life of electrical equipment.

Neutral first scramble chain and neutral wire are two common wires in circuits, and their differences are as follows:1The features are different:

The neutral wire is used to connect the load circuit and at the same time play the role of balancing the voltage. The neutral wire is connected to the grounding system for safety. 2.

The potential is different: in single-phase alternating current, the potential of the neutral wire is equal to the average value of the line voltage (i.e., the phase angle is 0), while the potential of the neutral wire is different in color: in domestic circuits, the color standard of the wire is red for the phase wire, black for the neutral line, and blue for the neutral wire.

However, in foreign circuits, the color standard may be different. 4.Security is different:

The access location and purpose of the neutral wire and the neutral wire are different, so it is necessary to pay attention to their correctness when using them in the sun. If not properly connected, it can cause circuit failure or danger. Especially when using electrical appliances, if the wires are broken, leakage and other problems, the correct connection method will affect people's life safety.

The neutral line is the neutral line. The IEC standard refers to the conductor that is loaded with multiphase unbalanced currents as the neutral (N-wire), which is often referred to as the "zero wire".

Under the operation mode of direct grounding of the neutral point, it should be done:

1) All the metal parts of electrical equipment that are not charged under normal conditions must be protected to zero or grounded;

2) In the same low-voltage distribution system of three-phase four-wire system, protection zero and protection grounding can not be mixed, that is, one part of the protection zero connection, and the other part of the protection grounding, but if the same equipment at the same time use protection zero and protection grounding is allowed, because its safety effect is better;

3) It is required that the neutral wire must be repeatedly grounded, because in the case of the neutral wire is disconnected, the zero connection equipment shell has a voltage of 220 volts to ground, which is absolutely not allowed.

1. Neutral line (N): It is mainly used in the working circuit, and the main line is drawn out after the neutral point of the transformer is grounded.

2. Ground wire (PE): not used for working circuit, only as a protective wire. Using the absolute "0" voltage of the earth, when the equipment shell leaks, the current will quickly flow into the ground, and even if there is an open circuit in the PE line, it will flow into the ground from the nearby grounding body.

After grounding from the neutral point of the transformer, the main line is drawn out and the grounding is repeated every 20-30 meters).

3. There is a point in the winding of the transformer and generator, which is equal to the absolute value of the voltage between the external terminals, which is called the neutral point, and the wire drawn from the neutral point is called the neutral wire.
