The socket, also known as the power socket, switch socket.The socket refers to a seat that can be inserted in one or more circuit wiring, which can be inserted into various wiring through it.This is convenient to connect with other circuits.Through the connection and disconnection between the line and the copper parts, the connection and disconnection of the circuit will be reached in the end.
How to choose the socket
1. Power sockets should adopt products that are qualified by the national product quality supervision department.Generally, mid -to -high -end products with flame retardant should be adopted, and low -grade and pseudo -inferior counterfeit products should be used;
2. The electric power socket in the residential house should be used in a safe socket, and a splash -proof socket should be used in humid places such as bathroom;
3. The rated current of the power socket should be more than 1.25 times that of the rated current of the known equipment.Generally, the rated current of single -phase power sockets is 10A, the special power socket is 16A, and the power distribution loading circuit and connection power supply method of special high -power household appliances should be selected according to the actual capacity;
4. In order to insert it convenient, one 86mm × 86mm unit panel, the number of combination sockets is best, the most (including switches) does not exceed three, otherwise the 146 panel porous socket is used;
5. For household appliances (such as washing machines) with electric shock dangers in the power supply supply, the socket that is turned off the power supply should be used.
6. In a more humid place, installing the socket should be installed at the same time.
Misunderstanding of socket use
With the popularity of household appliances, the number of power sockets at home has gradually increased.But if it is not installed properly, it will become a "invisible bomb" buried in the wall.According to the relevant survey data of the Ministry of Public Security, in the cumulative fire accidents in my country in the past 10 years, about nearly 30%of the total fire caused by power sockets, switches, and circuit breakers short circuit, ranking first of various types of fires.
Too low position
When installing the socket, many families feel that it is too high to be beautiful and will be installed in a lower concealed position.However, Dr. Xia Dong, Institute of Electric, Institute of Electric, the Chinese Academy of Sciences, said that it is easy to splash water into the socket when it is mopping, which leads to a leakage accident.The industry stipulates that it is best not to be less than 1.8 meters from the ground; the dark -loaded socket should not be less than 0.3 meters from the ground.The sockets in the kitchen and toilet should be more than 1.5 meters from the ground, and the socket of the air conditioner is at least 2 meters.
Free installation
The power wire must be cross -section of the copper wire.If you live in an old house, you must replace the original aluminum line with copper thread.Because the aluminum line is very easy to oxidize, it is easy to fire at the joint.There have been surveys that the incidence of electrical fires using aluminum lines is dozens of times the incidence of electrical fires.In addition, in order to be beautiful, many families will adopt the method of slotting and buried lines and dark pipes. Xia Dong reminds that when the wiring, you must follow the principle of "cable into the switch, zero line into the lamp head", but also set up leakage protection on the socket protection protection on the socket protection.Device.
Lack of protection
There are often water and oil fumes in the kitchen and bathroom. Therefore, it is best to install splash -proof box or plastic baffle on the socket panel.
In addition, when installing a three -hole socket, some decoration companies often let the ground -to -line lines be available, and even directly connect the ground wire to the gas pipeline.Professionals pointed out that these practices are dangerous, and the ground line is connected to the electrical shell. Once the electrical leakage is leaked, it will cause people to shock.
This method will cause the electrical appliances to run over load, which will cause a fire.Large -power electrical appliances such as air conditioners, washing machines, and range hoods are best to use independent sockets.Generally speaking, it is best to install 4 groups of sockets in the bedroom. The living room is one group per 2.5 square meters and a group of 1.2 square meters in the kitchen.
Lack of circuit
There is only one circuit in the old house. Once any line is short, the electricity consumption of the entire room will be paralyzed.Generally speaking, there are two or three circuits of the sockets. The kitchen and bathroom can go all the way, and the air conditioner uses a loop.
Old national standard
The universal hole socket, that is, the jack can be compatible with poles or tritinals at the same time, and even non -daily plug -in sockets such as British standards, US standards, and European standards.However, due to the large jack, the contact area of ??the socket and the electrical plug is too small, which can easily cause the contact film to cause the fire accident.
The two -core socket is easier to distinguish from the shape. There are two plugs on the plugs on the plug, but there are only two plugs on the socket itself. They are two -core problem sockets.This type of socket lacks a ground wire. During the use, once a certain insulation parts inside the electrical appliance is damaged, the current will be covered with the entire electrical surface. Because the current cannot be imported through the underground through the two -core socket, it is easy to cause electrical shock accidents.
Network meaning
Socket: Internet new meaning: It means that the joke is very cold, the smile is stiff, and it can also smile.
Sites: Network terms, indicating that they can be attacked or attacked, there are plugs in front, and the latter is the jack.
