Second, in the case of sufficient light, turn off the lighting power supply or reduce the number of lighting sources as much as possible.
3. If you are in office equipment such as computers, photocopiers and printers for a long time, please turn off the power as much as possible.
When people leave the room, please turn off the power of lamps, air conditioners and office equipment.
When the weather is hot, there is no need to adjust the air conditioning temperature too low, and 26 degrees is the most suitable. Close the doors and windows at the same time. It is often seen that someone's office adjusts the air conditioning temperature to 18 degrees, which causes the air conditioner to work all the time and increases the maintenance cost of the air conditioner. If the room temperature is adjusted too low, the temperature difference between indoor and outdoor is large, which is easy to cause a cold. In winter, the air conditioning temperature is not too high, and 18 degrees is more suitable.
It's unbearable hot in summer, and the air conditioning fans are all on. Fire and electric shock accidents caused by the use of these electrical appliances occur every year. How to make science of electricity safe is an important matter that every family must pay attention to. First of all, the bearing capacity of watt-hour meter and low-voltage line should be considered. The electric power that a watt-hour meter can withstand is similar to the value of voltage multiplied by current. The voltage of domestic electricity is 220 volts. For example, if a 2.5-amp watt-hour meter is installed at home, the power it can withstand is 550 watts, and a 600-watt rice cooker cannot be used. In this way, the electric power that a 5-amp watt-hour meter can bear is 1 100 watt.
Secondly, it should be considered that a socket allows several appliances to be plugged in. If the sum of the maximum power of all electrical appliances does not exceed the power of the socket, there is generally no problem. When using sockets with more than three pairs of jacks and using high-power appliances such as air conditioners, electric cookers, rice cookers and electric water heaters at the same time, the sum of the powers of these appliances should be calculated first. If the limited power of the socket is exceeded, the socket will burn out due to excessive current. At this time, the number of electrical appliances used at the same time should be reduced to keep the total power within the allowable range of the socket.
In addition, the installed circuit breaker must use the corresponding standard fuse. Do not use other metal wires instead, otherwise it will easily cause fire and damage electrical appliances. If the fire is caused by the fire of household appliances, you must cut off the power supply first and then put out the fire to avoid electric shock and personal injury.
Pay attention to safety when using power supply.
The popularity of household appliances such as refrigerators, televisions, washing machines and air conditioners has brought a lot of convenience to people's lives. But pay attention to the safe use of power supply to avoid unnecessary harm.
Electrical appliances with metal shell should use three-pin power plug. Some household appliances may leak electricity when they fail or get wet. Once the shell is charged, use a two-pin power socket, which may cause electric shock after human contact. Household appliances that consume a lot of electricity should use a separate power socket. Because both wires and sockets have specified current carrying capacity, if a variety of electrical appliances share a power socket, when the current exceeds its rated flow, the wires will heat up, and the plastic insulating sleeve may melt and cause combustion.
When the voltage fluctuates greatly, use a protector. In daily life, there is often an instantaneous power failure or power supply voltage fluctuation, which is a threat to the refrigerator. If the power supply is restored within a short time (3 ~ 5 minutes) after the power failure, the starting current of the refrigerator compressor is several times larger than the normal starting current, which may burn out the compressor.
