The manufacturer of household automatic voltage protectors introduces the household voltage range, precautions, and voltage and frequency standards

This article mainly introduces the household voltage range, precautions, voltage frequency standards, etc. by the manufacturer of household automatic voltage protectors. Understanding these related knowledge can help to use the automatic voltage protector correctly.

The manufacturer of household voltage protectors introduces the normal range of household voltage

The voltage of household electricity is usually AC, and the voltage range is generally 220 volts. This range is considered to be a normal voltage value. However, during the peak period of electricity consumption, the output loss of the power department is relatively large, so the staff of the power department will adjust the voltage to between 220 volts and 250 volts. However, the voltage may fluctuate slightly, as long as the fluctuation is within this range, it will not have a significant impact on electrical equipment. If the voltage exceeds this range, it may cause damage to the electrical equipment or affect its performance.
Warm reminder: The voltage of household electricity varies from country to country. China usually uses 220 volts, 50 Hz, and is generally single-phase AC. The constant safety voltage is a voltage of no more than 36 volts. When used, it cannot be in contact with the live wire or the conductor connected to the live wire, otherwise, there will be an electric shock accident, and the owner’s safety cannot be guaranteed.

The manufacturer of household automatic voltage protectors talks about precautions for household electricity use

To better protect the personal and property safety of the owner, we must also be careful when using electricity. The following are some detailed precautions.

1. Pay special attention to electrical safety during thunderstorms, and try not to use electrical appliances, because thunderstorms can cause the voltage outside to be too high, up to hundreds of thousands of volts, while the normal voltage indoors is only 220 volts, which will cause strong current from the outside to enter the room and burn out the fuse, or even cause a fire.
2. Whether you are replacing light bulbs or repairing home appliances, you must turn off the main switch in the room to prevent electric shock. If the insulation of the wires is peeling off, you must replace it immediately or wrap it with insulating tape. Do not touch the exposed wires, otherwise you cannot guarantee your safety.
3. Be careful when using electricity in daily life. If you have just washed your hands, you cannot plug or unplug the plug to avoid electric shock. If the plug is not unplugged, you cannot touch the socket with your hands, because people are also conductors. If they are not handled properly, electric shock will still occur.

The manufacturer of household voltage protectors introduces the differences in power systems

At present, the power systems of countries around the world usually adopt different voltage and frequency standards. According to the voltage, there are two types: low voltage of 100~130V and high voltage of 220~240V.

Automatic voltage protector manufacturers tell you that countries that pursue efficiency generally use high voltage and low frequency. For example, most European countries and my country use 220-240 volts and 50 Hz, while countries such as the United States and Canada focus more on safety and use 110 volts and 60 Hz.
