Is there a zero live wire for the 22OV plug on the TV board?

State a few facts:1The live wire and neutral line are for alternating current (220v 50hz for mains power in Chinese mainland), and the positive and negative poles are for direct current.

First of all, you have to figure this out. 2.The socket at home, the left and right holes are defined, and the left zero and right fire (facing the socket) are required.

Plumbers should follow this rule when renovating their homes. 3.However, the plug of some household appliances is two-phase (hole), and it can be plugged in both front and back, why?

Because this appliance does not need to distinguish between the live zero line and works normally. Moreover, its safety is not compromised by the neutral connection of the live wire (this is what the electrical design engineer should do, that is, even if the plumber turns the neutral line of the live wire in the first place (the same principle as the forward plug and the reverse plug, it will not become unsafe when used in the end). 4.

Someone else said that the three-pin socket at home, the kind with the grounding wire, may also be reversed between the live wire and the neutral wire, and the reason is the same as above. 5.The subject talked about distinguishing the zero line (or positive and negative poles) of the fire wire when connecting the electric light, one:

If you need to connect a direct current lamp, of course you need to distinguish between the positive and negative poles, otherwise it will not light up; 2: If it is a lamp that needs to be connected to AC power, distinguishing the neutral line of the live wire is generally based on safety considerations. Examples:

The thread of the lamp holder is required to be connected to the zero wire, and the bottom is connected to the live wire, why? Because the bottom position is more difficult to touch; The switch to control the light should be installed in the live line, why? When you turn off the switch and change the bulb, it's safe because you cut off the live wire, and there is no voltage at the lamp head.

6."Isn't that weird? Could it be that some of the chips automatically distinguish the conversion? After reading the above facts, you shouldn't still feel weird. By the way, there is no such thing as a distinction. Home electrical appliances work needs live wire and zero line, just like you need to buy a chicken leg with 15 yuan, whether you give five yuan first and then ten yuan, or give ten yuan and then five yuan, it will not affect the success of your purchase this time, as long as you hand over the ten yuan and five yuan.

The 220-volt plug on the TV version should also have zero live wires, but although there is this point in this plug, you can plug it in at will when you plug it in, and it doesn't matter.

In the process of using the TV version, the marked voltage must ensure that there is enough voltage and it is necessary to distinguish between the neutral line and the live wire.

As long as it is a 220V power cord, it will be divided into live wires and zero wires. No matter any household appliance, as long as it is a conventional household electricity, it will be distinguished in this way.

The input power supply of the TV is 220V alternating current, regardless of positive and negative poles, that is, there is no separation between live wire and neutral line.

There are step-down circuits and rectifier circuits on the circuit board inside the TV to make it meet the requirements of the TV.

Some TVs also come with a wide voltage design, and the input voltage can be used from 90V to 240V.

No, this one can be plugged in at will!

The 220-volt plug on the TV version does not have a zero live wire, and there is no problem even if the zero live wire is connected incorrectly.

The live wire and the neutral wire are just definitions, the two wires have a voltage difference, so the socket has electricity, at this time the neutral wire becomes the live wire, and the live wire becomes the neutral line.

Personally, I think that the entrance line should be no less than 6 square meters in this era, plug-in line square, lighting circuit trunk line square, room including hall and staircase access line can be separated, room and hall circuit and lamp head line can choose square line, staircase and channel lamp light number hail mu head power supply and loop can be used 1 square, air conditioning with 4 square direct switch, now is generally layered and then divided into modular cloth line, so that the cloth is enough for general household use.

Hello, n in AC 22ov represents the zero line, L is represented by the live wire. I hope mine is helpful to you, and at the same time I hope you can, pure hand.

Break the zero line. There are single-phase equipment, three-phase load asymmetry, zero point displacement.

First of all, if 380V is a 4-wire system, there is no zero wire, only ground wire, 220V takes the live wire and ground wire to the bulb, the bulb is bright and indicates that there is a loop, but it trips to indicate that the leakage protection has played a role. If the 380 end is a 5-wire system, you must find the right zero line!

Shame.

First of all, popular science:

Neutral line (n): Mainly used in working circuits, the main trunk line that leads from the neutral point of generators and transformers and is grounded. 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.

Ground Wire (PE): Not used in working circuits, 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).

The voltage of the live wire to the neutral wire and the regular ground wire is 220V, so it is normal for the equipment to work, but if there is a leakage protection switch, it will cause the switch to trip.

Normally, the protection neutral line is grounded near the transformer and the n line, that is, the two are connected together.

Normal. Protecting the zero line is just two more words in front of the zero line.

Very normal, brightness depends on the current of the load being stringed. The load is small, the brightness is low, the load is large, the current is close to the short circuit, and the brightness is bright to full bright.

The normal fire line is best to use an electric pen and the ground line can be connected to the leakage protection power tripping for the ground zero line without tripping. Of course, there is no abnormal situation.

Normal. The protective neutral wire should be called the protective ground wire, which should be grounded. The neutral wire, also known as the neutral wire, is also grounded in the transformer. So both the live line to the neutral line and the zero line to the zero line are 220V.

It can only be said that the rat was not electrocuted, and the possible reason:

1.The wires have no voltage.

2.The rats did not touch the line of fire at all.

There's no harm! Air conditioner is 750w, 5 horses is, this is refrigeration, heating you look at the nameplate, but I feel that 6 square is enough!

The diameter of the ground wire is smaller than the diameter of the power supply line, and the shell voltage is high in the event of leakage, and the ground wire is easily soldered. Therefore, the specification requires that the diameter of the ground wire is not less than the diameter of the power supply line.

In fact, in the case of the correct use of the leakage protector, it will be fine without a grounding wire.

The diameter of the ground wire is less than the zero live wire, and in the event of a short circuit to the ground, it is possible to burn the ground wire, so that the shell of the air conditioner is electrified, and there is a threat of electric shock to people.
