How to wire indoor lighting in the era of intelligence

indoor lighting is an important part of smart home. No matter how intelligent control and wireless communication technology are, we still have to live with a large number of cables to participate in lighting and control lighting equipment before the realization of such sci-fi technology as ultra long-distance wireless transmission of electric energy. Indoor lighting lines are mainly divided into three categories: exposed wiring, concealed wiring and mixed wiring

exposed wiring refers to the laying method in which there is no decorative ceiling board indoors, the line is laid along the wall and the top surface of the floor, or there is decorative ceiling board indoors, and the line is laid along the outer surface of the wall and ceiling board, and the line direction can be directly seen, which is called exposed wiring

concealed wiring refers to the wiring that is laid along the wall, decorative ceiling or floor top, and the direction of the line cannot be directly seen, which is called concealed wiring. During construction, indoor lighting sockets, weak current wires, etc. are poured into cement slabs after being fixed through pipes, and cannot be changed after pouring. In home decoration, it is usually slotted on the wall to take pipelines to sockets or switches or small electrical boxes. When it is necessary to pass through the whole room, it is usually slotted on the ground to run the pipe. If the machine is equipped with a computer, then the line. You can also use the ceiling or the internal corner line of the roof to route the pipeline

mixed light and dark wiring - it is characterized by a laying method in which the direction of one part of the line is visible and the direction of the other part of the line is invisible. For example, in some interior decoration projects, the electrical design adopts concealed wiring in the wall body, and the part entering the decorative ceiling layer is exposed wiring

the commonly used wiring methods include direct wiring of insulated conductors, wiring through pipes, and wiring through trunking:

direct wiring

direct wiring of insulated conductors. Two points should be paid attention to when laying:

1 The sheathed insulated conductor shall be used for direct wiring in the house, and its cross section shall not be greater than 6m ㎡, and the spacing between fixed points of wiring shall not be greater than 300mm

2. In the roof shed, wall and column of the building, it is strictly prohibited to use insulated wires for direct laying or open laying wiring, and metal pipes and metal trunking must be used for wiring

wiring through pipes

if the insulated wire is laid through pipes, pay attention that its voltage level should not be lower than AC 750V

1. Welded steel pipes shall be used for the wiring of metal pipes exposed in humid environment or directly buried in the soil. The wire steel pipe or galvanized steel pipe with the pipe wall thickness of not less than 1.5mm can be used for the wiring of metal pipes laid in a dry environment

2. In the environment with acid, alkali and salt corrosive media, flame-retardant plastic pipes should be used for corrosion, but in places suitable for mechanical damage, exposed laying should not be used. In case of concealed laying or buried laying, measures shall be taken to prevent mechanical damage at the section leading out of the ground; Galvanized steel pipe shall be used in dangerous explosion environment

3. When more than 3 insulated conductors pass through the same tube, the total cross-sectional area of the conductor (including the outer sheath) should not be greater than 40% of the net area in the tube. When two conductors pass through the same tube, the inner diameter of the tube should not be small. Intellectualization can improve the product quality level to 1.35 times the sum of the two conductor diameters

4. The electric wire pipe, hot water pipe and steam pipe strongly embody the spirit and concept of 'care'. When the steam pipe is laid at the same time, it should be laid under the hot water pipe and steam pipe; In case of difficulty, it can be laid on it, with a distance of no less than 0.3m from the hot water pipe and no less than 1.0m above the steam pipe; The parallel clear distance between wire pipe and other pipes shall not be less than 0.1m

5. For AC lines passing through metal tubes, all phase lines and zero lines shall be in the same tube

trunking wiring

trunking wiring should be used in places that are dry and not prone to mechanical damage. Trunking includes plastic (PVC) trunking, metal trunking, ground trunking, etc. Since the high-speed railway was built on the ground, the trunking has been connected with a distribution panel or outgoing panel every 4-8M It is very easy to pull wires in Putrajaya, so the distance is unlimited. Strong and weak current can go through the ground trunking adjacent to the same route, and can be connected to their sockets in the same first-line box. Of course, the ground trunking must be grounded and shielded, and the product quality should also be qualified. For example, the area of the office or business hall is large, and the computer is far from the wall. It is obviously inappropriate to use long jumpers to connect directly to the information socket and power socket on the wall. At this time, leave an outlet box near the ground trunking to solve the problems of network access and power supply at the same time

with the improvement of living standards, smart home is a common demand of people. In addition, with the promotion of IOT, it is believed that generic cabling will make a successful breakthrough in smart home. As IOT technology realizes the management and control of data room, the development of smart home will achieve greater success. At the same time, it will also drive generic cabling to make a breakthrough in the application field of smart home, and promote generic cabling to keep pace with life and conform to the pace of life
