First, the introduction of weak current socket
According to the intensity of power transmission, power applications can be divided into two categories: strong electricity and weak electricity. Building and building electricity generally refers to high-voltage alternating current above 220 V and 50 Hz. It mainly provides people with electric energy and converts it into other energy sources, such as air conditioning electricity, lighting electricity, power electricity and so on. There are two main types of weak electricity in intelligent buildings. One is low-voltage electric energy such as safe voltage grade and control voltage specified by the state, which is divided into AC and DC, with AC below 36V and DC below 24V, such as 24V DC control power supply or emergency lighting standby power supply. The other is information sources including sound, images and data, such as telephone, television and computer information.
Second, how to lay out weak current sockets
1, weak current socket installation layout in the living room.
(1) The living room is the center of people's party and life activities. The main equipment includes audio, air conditioning, television, network (providing network camera products), telephone, water dispenser, etc. , which is characterized by diversification of equipment and quantity. The design position ensures that the horizontal distance between the high-voltage and low-voltage sockets is greater than 0.2m If the distance is too close, it will easily cause electromagnetic interference and impact signals (signal amplification products are provided). Generally speaking, TV and stereo together need two sets of sockets. At the same time, temporary power supply is provided to two groups of sockets nearby.
(2) In addition, there are two sets of power sockets on both sides of the sofa opposite the TV, and telephone and network sockets are also installed on the wall. According to the location of air conditioners, water dispensers and other equipment, arrange the number of other exits. To sum up, in the living room, there are at least 9- 12 groups of TV and telephone sockets with strong network sockets, each with 1 group, which can meet people's living needs. Therefore, although there are many kinds of architectural planes, we can install the living room and the main wall in the living room and then make a comparative design.
2. Installation layout of weak current socket in bedroom
The main equipment in the bedroom includes telephone, TV, internet, air conditioning, etc. Determining the position of the bed is the key to the layout of the bedroom exit. There are 1 sets of power sockets, 1 sets of network and telephone sockets on both sides of the bedside, 2 sets of power sockets and 1 sets of TV, air conditioner and special air conditioner near the air outlet, 1 sets of spare other appropriate settings, and 6-8 sets of high-voltage sockets.
Third, the weak current socket matters needing attention
1. The conduit is laid directly on the ground. Under special circumstances, if it is necessary to walk around the wall or on the roof, it is necessary to indicate the irregular construction in the agreement in advance or fill in the customer approval form before construction.
2. The horizontal distance between power cord and socket and TV cable, network cable, audio-visual cable and socket should not be less than 500mm.
3, wear into the pipe wire joint should be located in the junction box, joint lap firmly, insulation tape package should be uniform and tight.
4. When connecting the wires of the switch and the screw lamp, the phase wire should be connected to the switch first, the phase wire led from the switch should be connected to the terminal in the center of the lamp, and the zero wire should be connected to the threaded terminal.
5. When wiring the power cord, the cross-sectional area of the conductor used should meet the maximum output power of the electrical equipment.
6. The connector of the cassette should be 30cm long, and all lines should be labeled, indicating the model, specification, date and project leader.
7. At the joint between the threading tube and the cassette, the cassette is not allowed to be cut, and the original tube hole must be opened to thread the threading tube out. The threading tube is kept 5 mm in the box.
Some of our friends didn't know much about putting some sockets at home at first, and didn't realize that there were weak sockets in the sockets and how to lay them out. But through the above article, friends all know what a weak socket is, or want to know about the decoration knowledge, you can also pay attention to it.
