Can 380V power be used as 220V electricity?

380V electricity, of course, can not be used as 220V, the moment the power is on, it will burn out the electrical appliances without tripping.

The national standard stipulates that the allowable value of voltage deviation is:

a. If the voltage of 35 thousand volts and above is supplied for power, the sum of the absolute value of the positive and negative deviations of the voltage shall not exceed 10% of the rated voltage;

b. For three-phase power supply of 10 thousand volts and below, the allowable deviation of voltage is 7% of the rated voltage. c. For 220 volt single-phase power supply, the allowable voltage deviation is +7% and -10% of the rated voltage.

Regardless of the voltage level, if the allowable voltage deviation is exceeded, it will cause damage to the electrical appliance.

Our country's 380V 220V power supply system, is the 380V and 220V common use of the system, the transformer's three-phase coil is connected into a star, the head end of the three-phase coil becomes a three-phase live wire respectively, the three ends, the ends are connected together as the common end, the common end connected together is grounded, the potential is zero, so it is called the zero line.

The three live wires drawn from the three heads are phase A, phase B and phase C, and the neutral line and any phase constitute a single-phase circuit with a voltage of 220V. The voltage between any two phases (between the live wires) is 380V. Two single-phase circuits are included between any two-phase line, enabling 380V and 220V to share a single system.

380V power supply refers to the phase-to-phase voltage of 308V, that is to say, the voltage between the three live wires is 380V, but each live wire to PE, is 220V, now the power supply system is three-phase four-wire or three-phase five-wire system, use the voltmeter to find out the three are live wires, make marks, find out the zero line, only use a live wire and a neutral line is 220V voltage.

If it is used at home, regardless of the price of electricity, the electrical appliances at home will be burned.

220V appliances cannot be used at 380V.

If the electrical appliance with a power supply voltage of 220V is connected to the 380V power supply, the electrical appliance will be damaged due to overvoltage. The power supply voltage of electrical appliances has a permissible working range, generally 10%, especially the maximum working voltage value has stricter regulations, if it exceeds this range, the electrical voltage can not work.

Precautions for using voltage:

1. The voltage transformer should be activated once and then twice, and the opposite should be done when it is deactivated.

2. When deactivating the voltage transformer, the voltage transformer should be considered to be protected by the volt pin and automatic device, and the relevant protection and automatic device should be deactivated in order to prevent the possibility of misoperation. It should also be considered that the AC voltage transfer switch of the faulty microwave should be invested in the operating bus voltage transformer.

3. When the voltage transformer is out of service or overhauled, its secondary should be separated, and the secondary fuse should be removed to prevent reverse power transmission.

4. The secondary parallel switch of the voltage transformer running with the double bus should be disconnected during normal operation, and the secondary switch of the voltage transformer should be put into operation after the bus tie switch is running and the room is not automatic, in order to prevent the voltage from bearing too large the unbalanced load of the voltage transformer. At the end of the inverted bus, the parallel switch is deactivated before the bus tie switch is changed to automatic. <>

Summary. The power of 380V electrical appliances and 220V can not be generalized, some can be used and some cannot be used. A small three-phase motor of 380V can be connected to a suitable capacitor with 220V.

Can 380v appliances be used with 220v electricity?

The power of 380V electrical appliances and 220V can not be generalized, some can be used and some cannot be used. A small three-phase motor of 380V can be connected to a suitable capacitor with 220V.

380 volt electrical appliances cannot be connected to 220 volt circuits. Because the voltage of 380 volts is much higher than that of 220 volts, the electrical appliances will not work, but they will not burn out. The voltage at both ends of the appliance can only work properly if it is equal to its rated voltage.

The actual voltage is too low to work with electrical appliances, the actual voltage is too high, the light ones are burned out, and the serious ones will cause disasters.

Normally, 380V appliances cannot be directly connected to 220V electricity. If the voltage is insufficient, the electrical appliance cannot work properly, for example, the electric furnace cannot reach the required temperature. However, most appliances will not be damaged.

No. 380 volts is an industrial voltage, generally speaking, 220 volts of civil electrical appliances connected to the industrial voltage will be burned due to excessive voltage, which is a more dangerous behavior; But it also depends on the specific equipment manual, some electrical appliances use a wide range of voltage, which can be used. China's low-voltage 380V power supply is generally a three-phase four-wire system, and its phase voltage is 220V.

If you want to use a 380V appliance at 220V, can you do it?

The 380V power supply can be connected to a 220V electrical appliance, but it should be used in the case of three phases and four wires. In fact, what we call 220V is itself part of a three-phase 380V power supply. If it is a three-phase three-wire, there is no neutral line, and 220V will appear in the "Y" connection in a completely balanced state, but 220V electrical appliances cannot be used in this way.

How can you use 380 volts with 220 volts? We know that the line voltage of the three phases in the AC power supply system is 380 volts, but for each phase it is 220 volts. The user can choose a three-phase power supply or a single-phase power supply according to the rated voltage of the load.

If the load voltage is single-phase, just introduce a one-phase power cable, a neutral wire and a ground wire into the three-phase power supply.

Can a 380 volt voltage be connected to a 220 volt electrical appliance? Hello dear, 380 volts can not be connected to 220 volt electrical appliances, this is because the rated voltage of 380 volts is greater than the rated voltage of 220 volt electrical appliances, the rated voltage between the two can not be matched, and the voltage of 380 volts is three-phase electricity, 22o volt electrical appliances are two-phase electricity for household use, if the voltage of 380 volts is connected to 220 volts electrical appliances, the electrical appliances will be burned out. I hope it can help you.

If my answer is helpful to you, please give a thumbs up (in the lower left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress. Finally, I wish you good health and a good mood!

The 380V voltage can be connected to 220V electrical appliances, but it needs to be modified.

The voltage between the live wire and the neutral wire is 220 volts, and the voltage between the live wire and the ground wire is also 220 volts. Temporary electricity can be made as a ground pile, and the ground pile must be done by professionals, safety first.

Transformation method: pseudo-zero line.

Precautions for ground piles: use No. 4 galvanized angle steel to sharpen one end as the grounding electrode, the depth of vertical driving into the ground should not be less than 2 meters, galvanized flat steel for connection, and its grounding resistance is required to be less than 4 ohms after it is done.

Summary. Yes, there is no problem, the three wires on the input side are actually one wire to ground, and the other two are connected to a 380V power supply. After connecting to the 220V power supply, there will be no damage to the transformer, but the output voltage should be lower than 13V

It's about 6V--9V.

The difference between three-phase power supply and single-phase power supply: the power supply sent by the generator is three-phase, and each phase of the three-phase power supply (as shown in Figure 1: X, Y, Z as shown in the four-wire three-phase power generation diagram) and its neutral point (such as O) can form a single-phase circuit to provide users with power energy.

Note that the AC circuit here can not be called the positive or negative pole, it should be called the phase wire (called the live wire in civil electricity) and the neutral wire (called the zero line in civil electricity).
