Misunderstanding of socket use

With the popularity of household appliances, there are more and more power outlets in the home. But if it is improperly installed, it will become a "stealth bomb" buried in the wall. According to the relevant survey data of the Ministry of Public Security, among the cumulative fire accidents in China 10, fires caused by short circuits of power sockets, switches and circuit breakers accounted for nearly 30% of the total, ranking first among all kinds of fires.

The position is too low

When installing a socket, many families think it is too high and unsightly, and will install it in a lower hidden position. However, Dr. Xia Dong from the Institute of Electrical Engineering, Chinese Academy of Sciences said that when mopping the floor, water could easily splash on the socket, leading to leakage accidents. According to industry regulations, the exposed socket should be no less than1.8m from the ground. The concealed socket shall not be less than 0.3m from the ground. The socket of kitchen and bathroom should be more than 1.5 meters from the ground, and the socket of air conditioner should be at least 2 meters.

Optional installation

The power cord must use copper wire section. If you live in an old house, you must replace the original aluminum wire with copper wire. Because the aluminum wire is easy to oxidize, the joint is easy to catch fire. A survey shows that the incidence of electrical fires in houses using aluminum wires is dozens of times that of copper wires. In addition, for the sake of beauty, many families will adopt the way of slotting and burying wires and laying concealed pipes. Xia Dong reminded that when wiring, the principle of "live wire enters the switch and zero wire enters the lamp holder" must be followed, and a leakage protection device should be installed on the socket.

Lack of protection

There is often water and oil smoke in the kitchen and bathroom. It is best to install a splash box or plastic baffle on the socket panel.

In addition, when installing three hole socket, some decoration companies often make the ground wire exist in name only, or even directly connect the ground wire to the gas pipeline. Professionals point out that these practices are very dangerous. The grounding wire is connected with the electrical shell. Once the electric appliance leaks electricity, it will cause people to get an electric shock.

* * * and

This practice will overload the electrical appliances and cause a fire. It is best to use independent sockets for high-power appliances such as air conditioners, washing machines and range hoods. Generally speaking, it is best to install four sets of sockets in the bedroom, one for every 2.5 square meters in the living room and one for every 1.2 square meters in the kitchen. Wrong idea

Less cycle

There is only one circuit in the old house. Once any line is short-circuited, the electricity consumption of the whole room will be paralyzed. Generally speaking, the socket can choose two or three loops, one for the kitchen and one for the bathroom, and one for the air conditioner.

Use the old national standard

Universal hole socket, that is, the jack can be compatible with two or three poles at the same time, even if it is a socket with non-daily plugs such as British standard, American standard and European standard. However, due to the large jack and the small contact area between the contact piece and the electric plug, this socket is easy to overheat the contact piece and lead to fire accidents.

The two-core socket is easy to distinguish in appearance. Any product with a three-pole socket on the plug board but only two pins on the plug itself is a two-core problem socket. This socket has no ground wire. In the process of use, once an insulation part inside the electrical appliance is damaged, the current will spread all over the surface of the electrical appliance. Because the current can't be led into the ground through the two-core socket, it is easy to cause electric shock accidents.

Network meaning

Socket: the new meaning of the network: it means that the joke is cold, the smile is stiff, and it can also mean a knowing smile.

Socket: network term, indicating that it can be attacked and accepted, with a plug in front and a jack in the back.
