EnglishElectricity is an indispensable and important energy source in life. While it brings convenience to people's lives, I believe everyone knows that electricity is different from other things. It cannot be seen or touched, but it is extremely dangerous. Power sockets are electrical appliances that are often used in daily life. How much do you know about the safety common sense of smart socket?
Question 1: Is there any danger when sparks appear when plugging in or pulling out electrical plugs?
When the electrical appliance (load) is inserted, there is current passing through it. The electrical current is very large when the electrical appliance is energized, and the plug and socket have contact resistance, so sparks are generated. If there is a switch on the power socket, it is recommended to turn off the switch when plugging or unplugging. If the plug is always sparking when the electrical appliance is working, this is not normal. This is due to the poor contact between the plug and the wire, and it should be handled as soon as possible, otherwise it is easy to cause a fire. Choosing a power socket with a silver contact switch can solve this problem very well.
Question 2: Can high-power electrical appliances use the same power socket at the same time?
try to avoid. Multiple high-power electrical appliances share one socket, causing the socket to heat up, affecting its service life, damaging electrical appliances and even causing fires. The editor reminds everyone not to plug high-power household appliances such as air conditioners and microwave ovens into sockets with small rated current values. It is best to use independent fixed sockets for high-power appliances, not mobile sockets.
Question 3: Will charging with the USB port of the power socket hurt the phone?
Has little effect. Nowadays, mainstream mobile phones on the market often have their own power management chips inside to monitor the voltage and current levels of the charging equipment. If the input voltage or input current is too high or too low, the system will automatically report an error. And if it fluctuates within the current and voltage that the mobile phone can accept, the battery loss will not be too high.
Therefore, in use, it is still necessary to use it. The capacity of the battery will decrease in about a year no matter how it is maintained. The difference is that the maintenance may be reduced by 5%, and the maintenance of the battery will decrease by 7%. After all, the internal components of the battery are aging. is unavoidable.
