What components will burn out if the neutral line is broken?

The zero line of the outgoing line from the home appliance meter is open, and the fan will not burn out, of course, the fan will not work.

The neutral line outside the meter is opened, and since it is generally three-phase electricity when entering the house, it is turned on when the power of the fan is turned on.

Mechanical speed control fans may burn out the capacitors and motors.

The electronic speed regulation may not only burn out the capacitor and motor, but also burn out the electronic speed regulation part.

Of course, if there is a fuse in the fan power input, the probability of the device burning out will be much reduced. Or even just damage the fuse.

Three-phase four-wire power supply line, if the total neutral line is broken, the voltage of a phase with a lighter single-phase load can reach more than 340 volts, and the coil of the fan will be burned out. If the neutral line (single-phase 220V power supply) in your home is broken, it will not damage the electric fan.

And there is only one zero line, which is shared by three companies. Once the main zero line is disconnected, these three live wires are connected to each other through the electrical equipment with their respective belts, and are connected in series into a circuit with a voltage of 380V.

If the neck of the electric fan is broken, it can be glued in the following ways: 1. If it is made of plastic, it can be glued with such super glue, but these glues cannot fill the gap, that is to say, the fracture should be a large gap; 2. If there is a small gap, it can be used in a small container, mixed with super glue and baby powder or prickly heat powder, stirred evenly, and filled in a paste; 3. If it is metal, it can only be welded.

If it is two electricity, the zero line will not cause the fan to break, because the lack of two electricity will not cause things to burn if one hectare is missing.

For three-phase wires, the voltage between the lines is 380V, if the phase load is not balanced, the voltage will not be distributed in each phase according to the usual 220, resulting in a heavy phase voltage increase, resulting in electrical appliances burning out or accidents.

At this point, the switch is off. Nothing will burn out.

Summary. Dear, hello, I'm glad to answer for you, the zero line burns out and causes the electrical appliances to burn out? A:

Not only will it burn the computer; If you use other household appliances, it will also burn; This is called an electrical appliance"Mass explosion"Phenomenon; Because the whole building generally uses three-phase four-wire power supply; After the zero line of a certain layer is broken, the three-phase load imbalance makes the zero point drift, which will make the zero line also live or cause the dual-purpose electrical appliances to become series connected to the 380 volt power supply through the zero line; At this point, the voltage will reach 380 volts; Thus burning out all 220-volt electrical appliances. Therefore, the construction requires that the zero line is not allowed to install a taekbreaker protector (fuse). As a user, once the zero line is broken, there is only the fire line at home.

As far as the whole building is concerned, the power supply is generally a three-phase five-wire system, because the zero line is connected to the whole building, and the live line is divided into ABC three-phase power supply ** each unit. If the neutral wire is disconnected at one point, the live wire will enter the socket through the neutral wire, which will turn the 220-volt socket into a 380-volt outlet. The voltage rises, so it burns out the computer or TV.

As soon as the neutral wire is broken, the two live wires are connected, so the appliance will burn out.

The zero line will burn out and cause the electrical appliances to burn out.

Hello, let you wait for a long time, is consulting information for your questions to answer, please be patient Dear, hello, I am happy to answer for you, the zero line burns out and causes the electrical appliances to burn out?

When the live wire is reversed with the pure zero line of the jujube, the fan will burn out.

Use the electric tester to determine which one is the live wire and which one is the neutral line stool. The neutral line, mainly used in the working circuit, leads out the trunk rough posture after grounding from the neutral point of the transformer; Live wire is mainly used for the transmission of electrical energy.

Therefore, when wiring the ceiling fan, it is necessary to distinguish which wire is the live wire and which wire is the neutral line, and it must not be reversed.

Causes of the charge of the neutral line.

Under normal circumstances, there should be no electricity on the neutral line. Therefore, once there is electricity, it must be a sign of failure; The simplest is electromagnetic induction, and at this time, the zero line is not well grounded and fails to form a loop;

Secondly, the electrical equipment leaks or the phase wire touches the shell, but the current is not large, so it has not tripped; The neutral line is electrified, and the neutral wire is definitely not well grounded; After the problem is solved, go to the cause of the device.

In the three-phase four-wire power supply system, if the neutral line is not well grounded or the ground terminal is broken, the consequence is that the potential of the neutral line is not equal to 0 when the three-phase load is unbalanced, that is, the neutral point is offset.

No. The live wire is reversed from the neutral wire, and the voltage level of the electrical appliance (fan) remains unchanged, which is still 220 volts.

If the zero line of the fire wire is reversed, some electrical appliances will be burned, and some electric banquets will not. The line should follow the principle of "left zero and right fire". Kaga is the zero line on the left and the fire line on the right.

Dear, I'm glad to answer for you: the zero line is burned out, causing the electrical appliances to burn outA: The situation under normal conditions of the zero line in the line:

Why do you burn electrical appliances when the zero line is broken at home? Many old electricians are vague and unclear1 Therefore, when we work on electrical appliances at home, we rely on one of the phases of three-phase electricity to form a loop with the zero line to load electrical work, and when designing the power distribution system of the whole building, the problem of three-phase balance is fully considered, and there will be no problems in electrical work. 2. Our household voltage is 220V, that is, single-phase electricity, single-phase electricity is the phase wire taken from one of the live wires of three-phase electricity, and then a single working zero line, and the normal voltage between the live wire and the zero line is about 220V; In the case of the total zero line disconnection in the line:

Why do you burn electrical appliances when the zero line is broken at home? Many old electricians are vague and unclear.1 If the total zero line is disconnected, the original flow of current through the circuit of the line live wire zero line is destroyed, and the current no longer flows through the zero line, but is transmitted in the live wire; 2. At this time, there is a voltage shift, the lower the resistance, the greater the voltage, and the smaller the resistance; That is to say, at the beginning, the voltage of less household appliances is large, and the electrical appliances are burned out, and the voltage of many household appliances is small, and the household appliances cannot work normally and cannot be brought up. 3 At this time, the situation is that the fire line of the power distribution system of the entire broken zero line constitutes a loop, that is, all electrical appliances are connected in series on the fire line;

The indoor 22ov power supply zero line can not be turned into a loop, and it is okay. If the outdoor is disconnected, other homes and your home are not using the same phase of electricity, and 38ov voltage will be generated through the common neutral line, which will inevitably burn out the electrical appliances.
