If the total power of high-power electrical appliances used in the dormitory is greater than this limit, the dormitory will trip and lose power.
This is also for security reasons.
Because if high-power electrical appliances are used for a long time, which exceeds the load capacity of the line, the wires will heat up until they burn red, which will ignite the insulation of the wires and cause huge security risks. This is also the main reason for frequent fire accidents in colleges and universities. Therefore, for the safety of myself and my classmates, it is necessary to prevent such incidents.
Common high-power power supply, such as:
Electric kettle: about1000 w ~1500 w.
Induction cooker: about 600W~2000W
Hair dryer: about 600W~ 1800W
Generally speaking, the power parameters of electrical appliances are marked with trademarks, so you can refer to the power yourself.
For example, the rated power of the vacuum cleaner shown above is 200W W.
In addition, it should be noted that many people should not use high-power electrical appliances at the same time.
For example, the power of notebook computers is about 30W~80W. If six people in the dormitory turn on their laptops at the same time, the maximum power is 480W W. This power is not high.
But the power of a desktop computer, for example, is about 80W~450W. If six people use desktop computers at the same time, only the computer can reach the highest power of 2700W W. If other electrical appliances are used at the same time, the power will be higher. If used for a long time at the same time, there will be safety hazards.
The solution is not to use it at the same time for a long time.
In addition, if there are not enough wire sockets in the dormitory, plug-ins will be used to expand the number of sockets.
If the quality of the socket you buy is not up to standard, it is more likely to cause safety problems. Is the actual load power of some inferior sockets far less than its standard rated power, or even less than 500W? If high-power electrical appliances are connected to such sockets, it is very easy to get hot and catch fire. There is a danger of electric shock after burning out the insulation of the wire. The damage caused is something we don't want to see.
Therefore, when using high-power electrical appliances, we should pay attention to the power limit of the dormitory to prevent tripping. And be sure to pay attention to the allowable rated power of your socket and use reliable electrical appliances.
