Which wire is wrong to elution and turn together?

It should be that the functional lines are all connected. may be launched at the same time.

Which wire is wrong to elution and turn together? Well, it's possible, try as I say. In the general two-phase circuit, the neutral wire and the live wire are reversed, which has no impact on the role of electrical appliances, but for personal safety, it is equivalent to a layer of protection.

If the fire wire and the neutral wire are reversed, it is equivalent to connecting the switch to the neutral wire. When it is necessary to change the light bulb, we always turn off the electric light, at this time, the metal part of the light bulb is electrified, and when the person touches the metal part of the light bulb, there is a risk of electric shock.

The live wire refers to any phase in the three-phase four-wire power grid A b C, and the neutral wire refers to the three-phase four-wire wire that has no voltage and current to the ground, and the ground wire is the grounding protection line. In order to make the alternating current have a very convenient power conversion function, usually the power transmission is in the form of three-phase four-wire, the three ends of the three-phase electricity are called phase wires, and the three tails of the three-phase electricity are connected together and called neutral wires"Zero line"。The reason why it is called the neutral line is that there is no current passing through the neutral line at the time of three-phase equilibrium, and then it is directly or indirectly connected to the earth, and the voltage with the earth is close to zero.

The mainland generally uses red to indicate the L (live) line, which is the line of fire; Blue represents the n (neutral) line, which is the zero line; The yellow-green color (commonly known as the flower line) indicates the ground line (E line).

Look at the red and blue lines.

Wouldn't you know if you tried it with a new turner? If the new one can be turned, then the previous one burns. If it still doesn't turn, it's a wiring error.

If you connect the wrong wire, you will only burn the handlebar, not other things, and the voltage of the handle is 4V, and even the bulb can't be burned.

The motor does not sound to prove that the motor is good, change the handlebar, and if it doesn't work, change the three-wire pipe in the motor, a total of 20 yuan to 30 yuan.

The handle wire is connected to the motor part: the motor item is reversed.

3 All hello: The air conditioner runs for a long timeUncontrolledThere should be two reasons: ,Refrigerantsleakage or inadequacy; ②Temperature sensorOr a faulty control circuit.

Hello, I don't think anyone can tell you how to connect each line specifically.

Because I don't know exactly what each line is.

Use a multimeter to measure the three wires of the motor, two of which have the largest resistance, and connect the capacitors.

The two terminals with the lowest resistance are connected to the power supply L and N. As long as you don't connect the neutral wire and the live wire together, you won't burn things.

Try it as I say.

How many items does your washing machine have? Which lines are used exactly?

A converter is a device that converts one signal into another. A signal is the form or carrier in which information exists. In automated instrumentation equipment and automatic control systems, one signal is often converted into another signal compared with a standard or reference quantity in order to connect two types of instruments, so the converter is often an intermediate link between two instruments (or devices).

Without opening the lid of a burned out converter, it is impossible to guess which component has burned out.

Your wiring is really messy, it's really ugly, horizontal and vertical is the basic requirement.

That won't help you see what's wrong.

Can this switch be pushed up? If it can be pushed, check the circuit to check the wiring at which intermediate point it should be, and the wiring in the socket should be connected.

Some people may think that it is not a big deal if the zero line of the live wire is reversed, anyway, the electrical appliances can still be used, in fact, from a professional point of view, this situation will not only damage the electrical appliances, but also easily cause safety accidents.

First of all, because the switch of the electrical appliance is to control the live wire, if the zero line of the live wire is reversed, it will cause the switch to control the zero line, in this case, even if the power is turned off, the electrical appliance is still live, which is easy to cause electric shock accidents.

Second, even if the power is turned off during voltage fluctuations or lightning strikes, electrical appliances can still be damaged.

Third, because even if the power is turned off, the electrical appliance is still connected to the live wire, which means that the electrical appliance is connected to the live wire all year round, and the circuit board and insulation layer in the electrical appliance are more likely to age.

Fourth, it will cause damage to air conditioners, refrigerators and other electrical appliances with compressors.

Fifth, most families use power strips, that is, plug boards, you can use the power test test, the zero line of the live wire will make the power plug in the state of power off is still live, touch even if the power has been turned off the power strip plug door, the same will occur life-threatening serious electric shock, families with children at home should pay special attention to this problem.

In short, safety is no trivial matter, the circuit standards formulated by the state are not a joke, and it is very necessary to strictly abide by the national standards.

If you first connect with the live wire, generally speaking, there is no danger on the socket will not have an impact, one end is connected to the wire, a week is connected to the live wire AC regardless of positive and negative which end is connected to which end, but the coffin is not good, the coffin must be the live wire into the control line out of the light, and then the lamp is connected to the zero line, so that when your switch is disconnected, the lamp is not charged, the switch is reversed and the light is electrified, and the switch is turned off if the energy-saving lamp is reversed. And when the switch is turned off, the light will not flash again.

If you use this kind of leakage protection at home, don't connect the wrong line when connecting the zero line of the fire wire, it is not safe to connect the wrong line of the fire wire.

There is a possibility of electric shock to the metal shell electrical appliances, because the electrical appliances are designed according to the provisions of the power switch. When you turn off the electrical switch, you actually turn off the zero wire, and when you stop taking a test pen, you can measure that the metal shell has a strong induction. There is a feeling of electric shock when touched by the hand, and in severe cases, it will cause injury to people.

The zero line of the live wire is connected to the wrong light, and the light will not be on, it must be changed, and the current equipment has been marked very clearly, **connect the live wire, **connect the zero line, and you will know it at a glance.

The wiring of the meter can refer to the wiring diagram on the meter cover.

The wiring is as follows: 1. The terminal block of the meter 1 is connected to the live wire.

2. The terminal block of the meter 3 is connected to the live wire.

3. The terminal block of meter 2 is connected to the zero line of the incoming line.

4. The terminal block of the meter 4 is connected to the zero line of the outgoing line.

Faulty wiring can lead to short circuits or even burnout of the meter.

Will the new meter burn out if the new meter is 1 connected to a large 2 connected to a zero and 3 out to a large 4 zero meter will burn out?

1. If the "zero line" and the "live wire" in the incoming line are reversed, the speed of the meter is uneven, resulting in inaccurate measurement of electric energy consumption.

2. If the two lines of the incoming line and the outgoing line are reversed, the phenomenon of "reversal" of the meter will occur.

3. The old mechanical meter inlet and outlet lines will be reversed, but it will not accelerate the rotation, and the speed is determined according to the load size. Today's smart meters are not reversed.

It is the incoming terminal, there is no right or wrong in this, which one can be connected to the zero line. Originally, the requirement was 1 live wire, but there may be changes outside our household line, so it doesn't matter. However, if the incoming and outgoing lines are reversed, the telegram will be reversed.

There will be no difference! As long as it's 1, 3 in, 2, 4 out! It's as if your socket isn't connected to the left-zero-right fire, and it still works with appliances!

If the meter is connected incorrectly, the meter will be damaged and a short circuit will occur.

It's been two years, and that is, the fire zero has not been received together, so it is not a big problem. It's been two years, and they've definitely charged you for your appliances, so it won't be a meter that will walk backwards or a meter that won't go. At most, the meter will have a reverse indication, no big problem.

Of course, for the docker, such a connection is not standardized.

Our daily electricity is alternating current, as long as you understand what alternating current is, you will understand, that will not affect the meter. As long as you don't plug the input line into the or pin at the same time, there is no problem. Ha ha.

What are the causes of miswiring of energy meters?

1. Causes and classification of miswiring of electric energy meters.

There are many reasons for the miswiring of the electric energy meter, one is in the metering cabinet, the wiring error occurs, the second is in the process of installing the electric energy meter, the wiring error, and the third is that some power users in the act of stealing electricity and stealing electricity, random wiring caused errors. It should be noted that the above three situations can occur at the same time, but relatively speaking, the more common is the wiring error in the installation link of the electric energy meter, if there is a problem of reversal of the polarity of the motor or the interchange of the secondary circuit, it may cause wiring errors. At the same time, if the voltage or current is disconnected, or the voltage phase sequence is wrong, it will also affect the accuracy of power metering.

There are three types of miswiring of electric energy meters, one is that the power line is reversed with the load line, which leads to the reversal of the pointer of the electric energy meter, which affects the metering of electric energy and the collection of electricity charges, and at the same time damages the interests of power enterprises, it will also bring great inconvenience to power users; The second is the reverse connection of the zero live wire, in this case, the zero line is in a state of disconnection, the power load is between the ground wire and the live wire, and there is no current passing through the electric energy meter, so the pointer will stop moving, affecting the result of power metering. The third is the wiring error of the current coil and the voltage line, in this case, the current generated by the excitation in the voltage coil may cause power latent movement when passing through the current coil, which affects the accuracy of power metering.

Therefore, when the power staff installs and wiring, they must operate in strict accordance with the relevant specifications, do a good job of acceptance, and ensure the accuracy of the wiring, so as to reduce the problem of power metering errors.

2. The impact of miswiring of the electric energy meter on power metering.

Simply put, the power metering work is to record the electric energy used by the user in the past period of time, in order to charge the electricity fee flat, the more common metering methods are direct meter metering and transformer meter metering, but no matter which method, the electric energy meter is the core device of metering, which directly affects the effectiveness of power metering.

Once the electric energy meter is installed, there is a wiring error, it may lead to three different situations, one is the normal rotation of the electric energy meter pointer, but there is an error between the measured data and the actual electricity consumption of the user, the second is that the electric energy meter pointer does not rotate, and the third is the reversal of the electric energy meter pointer. In either case, it will directly affect the accuracy of the power metering results. Therefore, doing a good job in the installation of electric energy meters and ensuring the accuracy and reliability of wiring is a problem that power technicians must focus on.

Can the meter burn out if it is connected to the electricity with electricity?

The speaker output power supply is 12VDC, and it is impossible to burn the power amplifier. If the wire is reversed, at most, the sound is small, and it is impossible to affect the host. Let's look at the other reasons

I don't think there's anything wrong with the reversing wire.

Definitely can, it should just be a part of the burned out, go fix it and see it, it's best to look at it on the spot.
