Intelligent Times Analysis of Common Methods for Indoor Lighting Wiring
Clear-laying cabling - that is, no decorative ceiling plate inside the room, laying along the wall and the top surface of the floor, or decorative ceiling plate in the room, and the line laying along the wall and the outer surface of the ceiling plate, can be seen directly to the direction of the laying of the line , Called the Ming Tu wiring.
Concealed cabling - refers to the laying of the line along the wall inside the decorative ceiling or floor top, can not directly see the direction of the line called the dark line. In the construction process, indoor lighting sockets, weak wires, etc., are fixed in the pipe and placed in the cement board. After the completion of pouring, they cannot be changed. In home furnishings, it is common to slot the wall to a wall outlet or a switch or a small electric box. When you need to pass through the entire room, you usually have to go through the floor and go through the pipeline. You can also use the ceiling or roof angle line to walk the pipeline.
Light and dark mixed wiring - its characteristics are that some of the lines can be seen in the direction of the other part of the line is not visible to the laying method. For example, in some interior decoration projects, the electrical design of the interior part is to adopt the concealed wiring in the wall part, and to enter the top part of the decoration hanging part, it is the wiring of the open floor.
Among the commonly used wire-laying methods are directly applied wires for insulated wires, through-pipe wiring, and trunk wirings:
<br> <br> direct the wiring lines directly deposited insulated conductor laid in two points should be noted:
1. The wiring in the house should be covered with insulated conductors. The cross-section should not exceed 6m, and the spacing between the fixed points of the wiring should not exceed 300mm.
2. It is strictly forbidden to use insulated conductors or direct wiring in the roof canopy, wall or pillar of the building. Metal pipes and metal trunking wiring must be used.
<br> <br> wear tube wiring the insulated wire through pipe laying, it is noted that the AC voltage level not less than 750V.
1. The surface of the metal pipe laid in a humid environment or buried directly in the earth should be welded steel pipe. The metal pipe wiring of an open or dark application in a dry environment may be a wire-pipe or galvanized steel pipe with a wall thickness of not less than 1.5 mm.
2. Corrosion of flame-retardant plastic pipes should be used in the environment where acid and alkali salts are used to corrode the medium. However, it is not appropriate to use the surface coating in places where mechanical damage is appropriate. When laying in the dark or buried, the section that leads to the ground should be taken to prevent mechanical damage; in the dangerous explosion environment, galvanized steel pipe should be used;
3〠When the three or more insulated conductors pass the same pipe, the total cross-sectional area of ​​the conductor (including the outer sheath) should not exceed 40% of the net area of ​​the pipe. When the two conductors pass the same pipe, the internal diameter of the pipe should not be less than 2 1.35 times the sum of the wire diameters;
4. When laying electric conduits, hot water pipes and steam pipes at the same time, they should be laid under the hot water pipes and steam pipes; when there are difficulties, they can be laid on the top and the distance from the hot water pipes should not be less than 0.3m. The above shall not be less than 1.0m; the parallel distance between the conduits and other conduits shall not be less than 0.1m.5. The AC line passing through the metal conduit shall be such that all the phase and neutral lines are within the same conduit;
Wiring trunking wiring trunking <br> <br> suitable for drying and less susceptible to mechanical damage place. Trays include plastic (PVC) trunking, metal trunking, and floor trunking. The ground trunk is connected to a distribution board or outlet board every 4~8m. In Putrajaya, it is very easy to pull the wire, so the distance is not limited. Strong and weak currents can be routed along the adjacent ground trunks, and they can be connected to their respective sockets in the same box. Of course, the grounding trough must be grounded and shielded, and the product quality must pass through. If the office or business hall is large, the computer is far from the wall. If you use long jumpers to connect information jacks and power outlets directly on the wall, it is obviously not appropriate. At this time, leaving an outlet box near the ground trunk can solve the problem of network access and power supply at the same time.
Conclusion:
With the improvement of living standards, home intelligence is a common demand. In addition to the advancement of the Internet of Things, it is believed that integrated wiring will have a breakthrough in smart homes. With the realization of the Internet of Things technology to achieve data management and control, smart home development will achieve greater success, but also to promote integrated wiring in the smart home application field has made great breakthroughs, to promote integrated wiring to keep up with the pace of life, comply with the rhythm of life .
Indoor lighting as an important part of smart home, even if no matter how intelligent control, no matter how innovative the wireless communication technology, wireless transmission of energy in the ultra-long distance, so that before the realization of science fiction technology, we have to cohabit with a large number of large number of cables Live to participate in lighting and controlling lighting equipment. The indoor lighting circuit is mainly composed of three types of surface wiring, concealed wiring, and mixed light and shade wiring.
